MT9V022: 1/3-Inch Wide-VGA Digital Image Sensor
Color Device Limitations
Color Device Limitations
The color version of the MT9V022 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” on page 34.
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 correc-
tion 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, Aptina
strongly recommends limiting use to linear operation if good color fidelity is required.
Output Data Format
The MT9V022 image data can be read out in a progressive scan or interlaced scan mode.
Valid image data is surrounded by horizontal and vertical blanking, as shown in Figure 6.
The amount of horizontal and vertical blanking is programmable through R0x05 and
R0x06, respectively. LINE_VALID is HIGH during the shaded region of the figure. See
“Output Data Timing” on page 13 for the description of FRAME_VALID timing.
