MT9D111 - 1/3.2-Inch 2-Megapixel SOC Digital Image Sensor
Feature Description
Micron Confidential and Proprietary
Figure 25: 64 Pixels in Normal and Column Skip 16x Readout Modes
Digital Zoom
Digital zoom is not used in SOC.
Binning
The sensor core supports 2 x 2 binning of 4 pixels of the same color. This mode can be
activated by asserting R0x20:0[15] (R0x21:0 if context A is used).
Binning is primarily used instead of 2x skip as a way of decimating the picture without
losing information. The effect of aliasing in preview mode is eliminated when binning is
used instead of just skipping rows and columns.
Activating binning has a few implications:
• It adds a level of skip, so the picture that comes out has the same dimensions as a pic-
ture read out with the next higher skip setting.
• It increases the minimum hblank and minimum row time requirements (see Table 33
and Table 34).
Binning Limitations
To achieve correct operation, the following conditions must be met:
