MT9V135: SOC VGA Digital Image Sensor General Description Preliminary General Description The MT9V135 is a VGA CMOS image sensor featuring Micron’ s breakthrough Digital- Clarity technology—a low-noise CMOS imaging technology that achieves CCD image quality (based on signal-to-noise ratio and low-light sensitivity) while maintaining the inherent size, cost, low power, and integration advantages of CMOS. The MT9V135 performs sophisticated processing functions including color recovery, color correction, sharpening, programmable gamma correction, auto black reference clamping, auto exposure, automatic 50Hz/60Hz flicker avoidance, lens shading correc- tion, auto white balance (AWB), and on-the-fly defect identification and correction. The MT9V135 outputs interlaced-scan images at 30 or 25 fps, supporting both NTSC and PAL video formats. The MT9V135 includes digital video output that can be switched to the NTSC/PAL encoder. This can be used in conjunction with an external DSP to provide an overlay (such as a logo or a menu screen) on top of the live video. The image data can be output on any one of three output ports: Composite analog video (support for both single-ended and differential) Low-voltage differential signalling (LVDS) CCIR 656 interlaced digital video in parallel 8-bit format Figure 1: MT9V135 Quantum Efficiency vs. Wavelength Table 3: MT9V135 Detailed Performance Parameters Parameter Value Output Gain 28 e-/LSB Read Noise 5.3 e-RMS at 16X Dark Current 1600 e-/pix/s at 70°C 350 450 550 650 750 850 950 1050 Quantum Efficiency [%] Wavelength [nm]

MT9V135: SOC VGA Digital Image Sensor Detailed Architecture Overview Preliminary Image Flow Processor The MT9V135 IFP consists of a color processing pipeline, and a measurement and control logic block (the camera controller). The stream of raw data from the sensor enters the pipeline and undergoes several transformations. Image stream processing starts with 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. 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 accumulate image brightness and color statistics. Based on these measurements, the IFP calculates updated values for exposure time and sensor analog gains that are sent to the sensor core through the control bus. Black Level Conditioning The sensor core black level calibration works to maintain black pixel values at a constant level, independent of analog gain, reference current, voltage settings, and temperature conditions. If this black level is above zero, it must be reduced before color processing can begin. The black level subtraction block in the IFP re-maps the black level of the sensor to zero prior to lens shading correction. Following lens shading correction, the black level addition block provides capability for another black level adjustment. However, for good contrast, this level should be set to zero. Digital Gain Controlled by auto exposure logic, the input digital gain stage amplifies the raw image in low-light conditions. (Range: x1–x8). Test Pattern A built-in test pattern generator produces a test image stream that can be multiplexed with the gain stage. The test pattern can be selected through register settings. Lens Shading Correction Inexpensive lenses tend to attenuate image intensity near the edges of pixel arrays. Other factors also cause signal and coloration differences across the image. The net result of all these factors is known as lens shading. Lens shading correction (LC) compensates for these differences. Typically, the profile of lens shading induced anomalies across the frame is different for each color component. Lens shading correction is independently calibrated for the color channels. Interpolation and Aperture Correction A demosaic engine converts the single color per pixel Bayer data from the sensor into RGB (10-bit per color channel). The demosaic algorithm analyzes neighboring pixels to generate a best guess for the missing color components. Edge sharpness is preserved as much as possible. Aperture correction sharpens the image by an adjustable amount. Sharpening can be programmed to phase out as light levels drop to avoid amplifying noise.

MT9V135: SOC VGA Digital Image Sensor Detailed Architecture Overview Preliminary Defect Correction This device supports 2D defect correction. In 2D defect detection/correction, pixels with values different from their neighbors by greater than a defined threshold are considered defects unless near the image boundary. The approach is termed 2D, as pixels on neigh- boring lines as well as neighboring pixels on the same line are considered in both detec- tion and correction. Color Correction To obtain good color rendition and saturation, it is necessary to compensate for the differences between the spectral characteristics of the imager color filter array and the spectral response of the human eye. This compensation, also known as color separation, is achieved through linear transformation of the image with a 3 x 3 element color correc- tion matrix. The optimal values for the color correction coefficients depend on the spectra of the incident illumination and can be programmed by the user. Color Saturation Control Both color saturation and sharpness enhancement can be set by the user, or adjusted automatically by tracking the magnitude of the gains used by the auto exposure algo- rithm. Automatic White Balance The MT9V135 has a built-in AWB algorithm designed to compensate for the effects of changing scene illumination on the quality of the color rendition. This sophisticated algorithm consists of two major submodules: A measurement engine (ME) performing statistical analysis of the image. A module selecting the optimal color corr ection matrix and analog color channel gains in the sensor core. While the default algorithm settings are adequate in most situations, the user can repro- gram base color correction matrices and limit color channel gains. The AWB does not attempt to locate the brightest or grayest elements in the image; it performs in-depth image analysis to differentiate between changes in predominant spectra of illumination and changes in predominant scene colors. Factory defaults are suitable for most appli- cations; however, a wide range of algorithm parameters can be overwritten by the user through the serial interface. Auto Exposure The auto exposure algorithm performs automatic adjustments to image brightness by controlling exposure time and analog gains in the sensor core, as well as digital gain applied to the image. The algorithm relies on the auto exposure measurement engine that tracks speed and amplitude changes in the overall luminance of selected windows in the image. Back light compensation is achieved by weighting the luminance in the center of the image higher than the luminance on the periphery. Other algorithm features include fast-fluctuating illumination rejection (time averaging), response-speed control, and controlled sensitivity to small changes. While the default settings are adequate in most situations, the user can program target brightness, measurement window, and other parameters as described above. The auto exposure algorithm enables compensation for a broad range of illumination intensities.
