MT9V111 - 1/4-Inch SOC VGA Digital Image Sensor General Description General Description This SOC VGA CMOS image sensor features ON Semiconductor's breakthrough, lownoise CMOS imaging technology that achieves CCD image quality (based on signal-tonoise ratio and low-light sensitivity) while maintaining the inherent size, cost and integration advantages of CMOS. The MT9V111 is a fully-automatic, single-chip camera, requiring only a power supply, lens and clock source for basic operation. Output video is streamed via a parallel eightbit DOUT port as shown in Figure 1. Output pixel clock is used to latch the data, while FRAME_VALID and LINE_VALID signals indicate the active video. The sensor can be put in an ultra-low power sleep mode by asserting the STANDBY pin. Output pads can also be tri-stated by de-asserting the OE# pin. The MT9V111 internal registers can be configured using a two-wire serial interface. The MT9V111 can be programmed to output progressive scan images up to 30 fps in an 8-bit ITU_R BT.656 (YCbCr) formerly CCIR656, YUV, 565RGB, 555RGB, or 444RGB formats. The FRAME_VALID and LINE_VALID signals are output on dedicated pins, along with a pixel clock that is synchronous with valid data.

Flicker avoidance PIXCLK FRAME_VALID LINE_VALID FLASH SRAM Line Buffers The MT9V111 can accept the input clock of up to 27 MHz, delivering 30 fps. With poweron defaults (see Appendix B for recommended defaults), the camera is configured to deliver 15 fps at 12 MHz and automatically slows down the frame rate in low-light conditions to achieve longer exposures and better image quality. Internally, the MT9V111 consists of a sensor core and an image flow processor. The sensor core functions to capture raw Bayer-encoded images that are input into the IFP as shown in Figure 1. The IFP processes the incoming stream to create interpolated, color-corrected output and controls the sensor core to maintain the desirable exposure and color balance. Sensor core and IFP registers are grouped into two separate address spaces, as shown in Figure 2. The internal registers can be accessed via the two-wire serial interface. Selecting the desired address space can be accomplished by programming register R1 which remains present in both register sets. MT9V111_DS Rev.

Figure 3 shows MT9V111 typical connections. For low-noise operation, the MT9V111 requires separate supplies for analog and digital power. Incoming digital and analog ground conductors can be tied together right next to the die. Both power supply rails should be decoupled to ground using capacitors. The use of inductance filters is not recommended.

MT9V111 - 1/4-Inch SOC VGA Digital Image Sensor Image Flow Processor Image Flow Processor Overview of Architecture The image flow processor consists of a color processing pipeline and a measurement and control logic block as shown in Figure 5. The stream of raw data from the sensor enters the pipeline and undergoes a number of transformations. Image stream processing starts from conditioning the black level and applying a digital gain. The lens shading block compensates for signal loss caused by the lens. Next, the data is interpolated to recover missing color components for each pixel and defective pixels are corrected. The resulting interpolated RGB data passes through the current color correction matrix (CCM), gamma, and saturation corrections and is formatted for final output. The measurement and control logic continuously accumulates statistics about image brightness and color. Indoor 50/60 Hz flicker is detected and automatically updated when possible. Based on these measurements the IFP calculates updated values for exposure time and sensor analog gains, which are sent to the sensor core via the communication bus. Color correction is achieved through linear transformation of the image with a 3 x 3 color correction matrix. Color saturation can be adjusted in the range from zero (black and white) to 1.25 (125% of full color saturation). Gamma correction compensates for non-linear dependence of the display device output vs. driving signal (e.g. monitor brightness vs. CRT voltage). Output and Formatting Processed video can be output in the form of a standard ITU_R BT.656 or RGB stream. ITU_R BT.656 (default) stream contains 4:2:2 data with optional embedded synchronization codes. This kind of output is typically suitable for subsequent display by standard video equipment. For JPEG/MPEG compression, YUV/ encoding is suitable. RGB functionality is provided to support LCD devices. The MT9V111 can be configured to output 16-bit RGB (RGB565), 15-bit RGB (RGB555) as well as two types of 12-bit RGB (RGB444). The user can configure internal registers to swap odd and even bytes, chrominance channels and luminance and chrominance components to facilitate interface to application processors. MT9V111_DS Rev.

MT9V111 - 1/4-Inch SOC VGA Digital Image Sensor Image Flow Processor Figure 5: Image Flow Processor Block Diagram IMAGE SENSOR LENS CORRECTION DEMOSAICING AE, AWB, FLICKER AVOIDANCE COLOR CORRECTION FLASH CONTROL GAMMA CORRECTION OUTPUT FORMATTING The MT9V111 features smooth, continuous zoom and pan. This functionality is available when the IFP output is downsized in the decimation block. The decimation block can downsize the original VGA image to any integer size, including QVGA, QQVGA, CIF and QCIF with no loss to the field of view. The user can program the desired size of the output image in terms of horizontal and vertical pixel count. In addition the user can program the size of a region for downsizing. Continuous zoom is achieved every time the region of interest is less than the entire VGA image. The maximum zoom factor is equal to the ratio of VGA to the size of the region of interest. For example, an image rendered on a 160x120 display can be zoomed by 640/160=480/120=4 times. Continuous pan is achieved by adjusting the starting coordinates of the region of interest. Also a fixed 2X up-zoom is implemented by means of windowing down the sensor core. In this mode the IFP receives a QVGA-sized input data and outputs a VGA-size image. The sub-window can be panned both vertically and horizontally by programming sensor core registers. The MT9V111 supports both LED and Xenon-type flash light sources using a dedicated output pad. For Xenon devices the pad generates a strobe to fire when the imager's shutter is fully open. For LED the pad can be asserted or de-asserted asynchronously.

Note: See Sensor Core (MT9V011) data sheet for more details. Figure 6: Sensor Core Block Diagram Control Register Active Pixel Sensor Array Communication Bus to IFP Timing and Control Clock Sync. Signals Analog Processing 10-bit Data to IFP ADC The sensor core's pixel array is configured as 668 columns by 496 rows (shown in Figure 7). The first 18 columns and the first 6 rows of pixels are optically black and can be used to monitor the black level. The last column and the last row of pixels are also optically black. The black row data is used internally for the automatic black level adjustment. There are 649 columns by 489 rows of optically active pixels, which provides a four-pixel boundary around the VGA (640 x 480) image to avoid boundary affects during color interpolation and correction. The additional active column and additional active row are used to allow horizontally and vertically mirrored readout to also start on the same color pixel, as shown in Figure 7.

Propagation Delays for FRAME_VALID and LINE_VALID Signals The LINE_VALID and FRAME_VALID signals change on the same falling master clock edge as the data output. The LINE_VALID goes HIGH on the same falling master clock edge as the output of the first valid pixel's data and returns LOW on the same master clock falling edge as the end of the output of the last valid pixel's data.

MT9V111 - 1/4-Inch SOC VGA Digital Image Sensor Serial Bus Description Serial Bus Description Registers are written to and read from the MT9V111 through the two-wire serial interface bus. The sensor is a serial interface slave and is controlled by the serial clock (SCLK), which is driven by the serial interface master. Data is transferred into and out of the MT9V111 through the serial data (SDATA) line. The SDATA line is pulled up to 2.8V offchip by a 1.5K resistor. Either the slave or master device can pull the SDATA line down-- the serial interface protocol determines which device is allowed to pull the SDATA line down at any given time. The registers are 16 bits wide and can be accessed through 16bit or eight-bit two-wire serial bus sequences. Protocol The two-wire serial interface defines several different transmission codes, as follows: * a start bit * the slave device eight-bit address. SADDR is used to select between two different addresses in case of conflict with another device. If SADDR is LOW, the slave address is 0x90; if SADDR is HIGH, the slave address is 0xB8. * a(n) (no) acknowledge bit * an eight-bit message * a stop bit Sequence A typical read or write sequence begins by the master sending a start bit. After the start bit, the master sends the slave device's eight-bit address. The last bit of the address determines if the request will be a read or a write, where a "0" indicates a write and a "1" indicates a read. The slave device acknowledges its address by sending an acknowledge bit back to the master. If the request was a write, the master then transfers the 8-bit register address to which a write should take place. The slave sends an acknowledge bit to indicate that the register address has been received. The master then transfers the data eight bits at a time, with the slave sending an acknowledge bit after each 8 bits. The MT9V111 uses 16-bit data for its internal registers, thus requiring two eight-bit transfers to write to one register. After 16 bits are transferred, the register address is automatically incremented, so that the next 16 bits are written to the next register address. The master stops writing by sending a start or stop bit. A typical read sequence is executed as follows. First the master sends the write-mode slave address and eight-bit register address, just as in the write request. The master then sends a start bit and the read-mode slave address. The master then clocks out the register data eight bits at a time. The master sends an acknowledge bit after each eightbit transfer. The register address is auto-incremented after every 16 bits is transferred. The data transfer is stopped when the master sends a no-acknowledge bit. The MT9V111 allows for eight-bit data transfers through the two-wire serial interface by writing (or reading) the most significant eight bits to the register and then writing (or reading) the least significant eight bits to Reg0x7F (127). Bus Idle State The bus is idle when both the data and clock lines are HIGH. Control of the bus is initiated with a start bit, and the bus is released with a stop bit. Only the master can generate the start and stop bits. MT9V111_DS Rev. N 5/15 EN 21 (c)Semiconductor Components Industries, LLC,2015. MT9V111 - 1/4-Inch SOC VGA Digital Image Sensor Serial Bus Description Start Bit The start bit is defined as a HIGH-to-LOW transition of the data line while the clock line is HIGH. Stop Bit The stop bit is defined as a LOW-to-HIGH transition of the data line while the clock line is HIGH. Slave Address The 8-bit address of a two-wire serial interface device consists of seven bits of address and 1 bit of direction. A "0" in the least significant bit (LSB) of the address indicates write mode, and a "1" indicates read mode. The write address of the sensor is 0xB8, while the read address is 0xB9; this only applies when SADDR is set HIGH. Data Bit Transfer One data bit is transferred during each clock pulse. The serial interface clock pulse is provided by the master. The data must be stable during the HIGH period of the serial clock--it can only change when the two-wire serial interface clock is LOW. Data is transferred eight bits at a time, followed by an acknowledge bit. Acknowledge Bit The master generates the acknowledge clock pulse. The transmitter (which is the master when writing, or the slave when reading) releases the data line, and the receiver indicates an acknowledge bit by pulling the data line LOW during the acknowledge clock pulse. No-Acknowledge Bit The no-acknowledge bit is generated when the data line is not pulled down by the receiver during the acknowledge clock pulse. A no-acknowledge bit is used to terminate a read sequence. MT9V111_DS Rev. N 5/15 EN 22 (c)Semiconductor Components Industries, LLC,2015. MT9V111 - 1/4-Inch SOC VGA Digital Image Sensor Two-wire Serial Interface Sample Write and Read Sequences (with Saddr = 1) Two-wire Serial Interface Sample Write and Read Sequences (with SADDR = 1) 16-Bit Write Sequence A typical write sequence for writing 16 bits to a register is shown in Figure 16. A start bit given by the master, followed by the write address, starts the sequence. The image sensor will then give an acknowledge bit and expects the register address to come first, followed by the 16-bit data. After each eight-bit the image sensor will give an acknowledge bit. All 16 bits must be written before the register will be updated. After 16 bits are transferred, the register address is automatically incremented, so that the next 16 bits are written to the next register. The master stops writing by sending a start or stop bit.

First the master has to write the register address, as in a write sequence. Then a start bit and the read address specifies that a read is about to happen from the register. The master then clocks out the register data eight bits at a time. The master sends an acknowledge bit after each eight-bit transfer. The register address is auto-incremented after every 16 bits is transferred. The data transfer is stopped when the master sends a no-acknowledge bit.

However, certain hosts only support 8-bit serial communication access. The camera provides a special accommodation for these hosts. To be able to write one byte at a time to the register a special register address is added. The 8-bit write is done by first writing the upper 8 bits to the desired register and then writing the lower 8 bits to the special register address (Reg0x7F). The register is not updated until all 16 bits have been written. It is not possible to just update half of a register. In Figure 18, a typical sequence for 8-bit writing is shown. The second byte is written to the special register (Reg0x7F).

Auto exposure, automatic white balance, 60Hz flicker avoidance, defect correction, and automatic noise suppression in low light conditions are enabled. The frame rate is controlled by AE and can be slowed down to 5 fps in low light. Lens shading correction is disabled. Gamma correction uses gamma = 0.6. Image data are output in YCbCr ITU_R.BT.656 VGA format, with Y, Cb, and Cr values ranging from 16 to 240. The use of the non-default register settings shown in Table 10 are recommended to optimize sensor performance in the above configuration.

Auto Exposure Target image brightness and accuracy of AE are set by IFP R46[7:0] and R46[15:8], respectively. For example, to overexpose images, set IFP R46[7:0] = 120. To change image brightness on LCD in RGB preview mode, use IFP R52[15:8]. AE logic can be programmed to keep the frame rate constant or vary it within certain range, by writing to IFP R55[9:5] one of the values tabulated in Table 12.

The speed should be high in preview modes and lower for video output to avoid sudden changes in brightness between frames. Auto exposure is disabled by setting IFP R6[14] = 0. When AE, AWB, and flicker avoidance are all disabled (IFP R6[14] = 0, IFP R6[1] = 0, and IFP R8[11] = 0), exposure and analog gains can be adjusted manually (see core registers R9, R12, and R43 through R46).

Use IFP R37[2:0] and R37[6:3] to speed up AWB response. Please note that speeding AWB up may result in color oscillation. If necessary, AWB range can be restricted by changing the upper limit in IFP R36[14:8] and lower limit in IFP R36[6:0]. Flicker Avoidance Use IFP R91 to choose automatic/manual, 50Hz/60Hz flicker avoidance and IFP R8[11] = 0 to disable this feature. Flash For flash programming, see IFP R152 description.

Table 13: Decimation, Zoom, and Pan Note: Ifp Registers CIF Output (Correct Aspect Ratio) QVGA Output 2:1 Zoom QVGA Output 1:1 Zoom R165 R166 R167 R168 R169 R170 26 586 352 0 480 288 160 320 320 120 240 240 0 640 320 0 480 240 For fixed 2x upsize zoom, set core R30[0] = 1. Interpolation Use IFP R5[2:0] to adjust image sharpness. By default, sharpness is automatically reduced in low-light conditions (see IFP R5[3]). For RGB565 16-bit capture, set IFP R6[12] = 0 and IFP R5[3] = 0 to avoid contouring. Special Effects To switch from color to gray scale output, set IFP R8[5] = 1. Contact a ON Semiconductor FAE for register settings producing other special effects (e.g. sepia output). Image Mirroring To mirror images horizontally, set core R32[14] = 1 and IFP R8[0] = 1. To flip images vertically, set core R32[15] = 1 and IFP R8[1] = 1. Test Pattern See IFP R72 and IFP Reg58[5:3] description. MT9V111_DS Rev. N 5/15 EN 28 (c)Semiconductor Components Industries, LLC,2015. MT9V111 - 1/4-Inch SOC VGA Digital Image Sensor Appendix B - Overview of Programming Gamma Correction See Table 14 and Table for register settings required to setup non-default gamma correction. Please note that these settings determine output signal range. Use YCbCr settings with ITU_R BTU-compatible devices. Use YUV settings for JPEG capture and RGB preview; switching to YUV mode requires setting IFP R52 = 0 and IFP R53 = 65281.
