General Description
This is a single-chip digital color imaging device. It incorporates a 352 x 288 sensor array operating at
max. 30 frames per second in progressive manner. Each pixel is covered by a color filter, which formed a
so-called Bayer pattern. Correlated double sampling is performed by the internal ADC and timing
circuitry.
Depending on the brightness of the scene, the raw data can be adjusted by the digital gain for all pixels, or
be adjusted separately for the 4 Bayer pattern pixels. This is done either by the built-in automatic
exposure control circuit, or can be done manually by the external CPU via serial bus control.
The data are then processed by the color interpolation module so that each pixel will get a complete set of
RGB values. To correct or enhance color, automatic white balance circuit is built-in. The user may
perform white balancing and color correction manually by external CPU via serial bus too. Color
saturation control is programmable via serial bus, if user is not satisfied with the default settings
At the final stage, the gamma correction can also be performed, in addition to default value. The output
formats include 8/16-bit YUV or YCbCr, 24-bit, 16-bit RGB, and 8-bit raw data which can be fed to other
DSP, color processing, or compression chips.
