Definition
In addition to windowing mode— in which smaller resolution (CIF, QCIF, user-selected
size frame) is obtained by selecting a small window from the sensor array—the MT9V022
provides the ability to show the entire image captured by the pixel array with smaller res-
olution by pixel binning. Pixel binning is performed by combining signals from adjacent
pixels by averaging. There are two options: binning 2 and binning 4.
When binning 2 is on, 4 pixel signals from 2 adjacent rows and columns are combined.
In the case of binning 4 mode, 16 pixels are combined from 4 adjacent rows and col-
umns. Binning may be used in conjunction with image flip. The binning operation
increases SNR but decreases resolution. Enabling row bin2 and row bin4 improves frame
rate by 2x and 4x, respectively. Column binning does not increase the frame rate.
The user may set the sensor in standby mode by setting STANDBY HIGH. Once the
MT9V022 detects that STANDBY is asserted, it completes the current frame before dis-
abling the digital logic, internal clocks, and analog power enable signal. To release the
sensor out from the standby mode, reset STANDBY back to LOW.
In this mode, the MT9V022 first captures a programmable number of frames and then
goes into a sleep period for five minutes. During the sleep period, all of the analog cir-
cuitry of the MT9V022 is powered-down and only a small portion of the digital circuitry
remains powered.
The MT9V022 thermometer circuit provides a digital output vs. temperature that is
accessible via the serial interface. The resolution of the thermometer is approximately 1
LSB per degree Celsius.
