By setting bit 5 of R0x0D the readout order of the columns is reversed, as shown in
Figure 28 on page 53.
By setting bit 4 of R0x0D the readout order of the rows is reversed, as shown in Figure 29
on page 53.
In addition to windowing mode in which smaller resolution (CIF, QCIF) is obtained by
selecting small window from the sensor array, the MT9V032 also provides the ability to
show the entire image captured by pixel array with smaller resolution by pixel binning.
Pixel binning is based on 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 adja-
cent rows and columns are combined. In binning 4 mode, 16 pixels are combined from 4
adjacent rows and columns. The image mode may work 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. The
feature of column binning does not increase the frame rate in less resolution modes.
