COLOR DEVICE LIMITATIONS
The color version of the MT9V032 does not support or
offers reduced performance for the following
functionalities.
Pixel Binning
Pixel binning is done on immediate neighbor pixels only;
no facility is provided to skip pixels according to a Bayer
pattern. Therefore, the result of binning combines pixels of
different colors. For more information, see “Pixel Binning”.
Interlaced Readout
Interlaced readout yields one field consisting only of red
and green pixels and another consisting only of blue and
green pixels. This is due to the Bayer pattern of the CFA.
Automatic Black Level Calibration
When the color bit is set (R0x0F[2]=1), the sensor uses
GREEN1 pixels black level correction value, which is
applied to all colors. To use calibration value based on all
dark pixels offset values, the color bit should be cleared.
Other Limiting Factors
Black level correction and row−wise noise correction are
applied uniformly to each color. Automatic exposure and
gain control calculations are made based on all three colors,
not just the green luma channel. High dynamic range does
operate; however, ON Semiconductor strongly recommends
limiting use to linear operation if good color fidelity is
required.
