MT9P031: 1/2.5-Inch 5-Mp Digital Image Sensor Functional Overview Functional Overview The MT9P031 is a progressive-scan sensor that generates a stream of pixel data at a constant frame rate. It uses an on-chip, phase-locked loop (PLL) to generate all internal clocks from a single master input clock running between 6 MHz and 27 MHz. The maximum pixel rate is 96 megapixels per second, corresponding to a clock rate of 96 MHz. Figure 3 illustrates a block diagram of the sensor. Figure 3: MT9P031 Block Diagram Pixel Array EXTCLK RESET# STANDBY# OE# Serial Interface Output 2,752H x 2,004V Array Control TRIGGER Analog Signal Chain Data Path SCLK SDATA SADDR PIXCLK DOUT[11:0] LINE_VALID FRAME_VALID STROBE The sensor is programmed via the two-wire serial bus, which communicates with the array control, analog signal chain, and digital signal chain. The core of the sensor is a 5megapixel active-pixel array. The timing and control circuitry sequences through the rows of the array, resetting and then reading each row in turn. In the time interval between resetting a row and reading that row, the pixels in the row integrate incident light. The exposure is controlled by varying the time interval between reset and readout. Once a row has been read, the data from the columns are sequenced through an analog signal chain (providing offset correction and gain) and then through an ADC. The output from the ADC is a 12-bit value for each pixel in the array. The ADC output passes through a digital processing signal chain (which provides further data path corrections and applies digital gain). The pixel data are output at a rate of up to 96 Mp/s, in addition to frame and line synchronization signals. PDF: 09005aef824c993e/Source: 09005aef824c9943 MT9P031_5100_PB_2.fm - Rev.

MT9P031: 1/2.5-Inch 5-Mp Digital Image Sensor Functional Overview Default Readout Order By convention, the sensor core pixel array is shown with pixel (0,0) in the top right corner (see Figure 6). This reflects the actual layout of the array on the die. By default data is first read out of the sensor at pixel (16,54). When the sensor is imaging, the active surface of the sensor faces the scene, as shown in Figure 6. When the image is read out of the sensor, it is read one row at a time, with the rows and columns sequenced, as shown in Figure 7.

MT9P031: 1/2.5-Inch 5-Mp Digital Image Sensor Functional Overview Readout Modes Subsampling By default, the resolution of the output image is the full width and height of the FOV as defined above. The output resolution can be reduced by two methods: skipping and binning. Row and column skip modes use subsampling to reduce the output resolution without reducing field-of-view. The MT9P031 also has row and column binning modes, which can reduce the impact of aliasing introduced by the use of skip modes. This is achieved by the averaging of two or three adjacent rows and columns (adjacent same-color pixels). Both 2X and 4X binning modes are supported. Rows and columns can be binned independently. Skipping Skipping reduces resolution by using only selected pixels from the FOV in the output image. In skip mode, entire rows and columns of pixels are not sampled, resulting in a lower-resolution output image. A skip 2X mode skips one Bayer pair of pixels for every pair output. Skip 3X skips two pairs for each one pair output. Rows and columns are always read out in pairs. Binning Binning reduces resolution by combining adjacent, same-color imager pixels to produce one output pixel. All of the pixels in the FOV contribute to the output image in bin mode. This can result in a more pleasing output image with reduced subsampling artifacts. It also improves low-light performance. For columns, the combination step can be either an averaging or summing operation. Depending on lighting conditions, one or the other may be desirable. In low-light conditions, summing produces a gain roughly equivalent to the column bin factor. Only certain combinations of binning and skipping are allowed.
