pixel array, and/or by binning 2 x 2 groups of pixels of the same color. Since decimation
by skipping (that is, deletion) can cause aliasing (even if pixel binning is simultaneously
enabled), it is generally better to change image size only by cropping and pixel binning.
The image cropping and decimator module can be used to do digital zoom and pan. If
the decimator is programmed to output images smaller than images coming from the
sensor core, zoom effect can be produced by cropping the latter from their maximum
size down to the size of the output images. The ratio of these two sizes determines the
maximum attainable zoom factor. For example, a 1600 x 1200 image rendered on a
160 x 120 display can be zoomed up to 10 times, since 1600/160 = 1200/120 = 10. Pan-
ning effect can be achieved by fixing the size of the cropping window and moving it
around the pixel array.
The YUV data stream emerging from the decimator module can either exit the color
pipeline as-is or be converted before exit to an alternative YUV or RGB data format.
The JPEG compression engine in the MT9D131 is a highly integrated, high-performance
solution that can provide sustained data rates of almost 80 MB/s for image sizes up to
1600 x 1200. Additionally, the solution provides for low power consumption and full
programmability of JPEG compression parameters for image quality control.
• One each for luminance and chrominance (active)
• Support for three pairs of quantization tables—two pairs serve as a backup for buffer
• 2 AC, 2 DC tables—separate for luminance and chrominance
