Windowing Capabilities
Registers control the blanking time in a row (called column fill-in or horizontal blanking)
and between frames (vertical blanking). Horizontal blanking is specified in terms of
pixel clocks. Vertical blanking is specified in terms of row readout times.
The user can change the number of columns and rows read out as well as the horizontal
and vertical blanking times to obtain different frame rates.
In addition to having the flexibility to read out smaller standard formats, the sensor can
also read out nonstandard formats. This is particularly useful for zooming in on a partic-
ular segment of the image to perform high-speed mathematical calculations (for
example, a high-speed viewfinder or autofocus applications).
Applications with an autofocus mode may require more horizontal than vertical resolu-
tion. That way, the imager can window to the midsection of the array by changing the
row start address and the window height.
The MT9T031change registers can obtain the different frame rates. The imager can also
perform row skip modes to obtain a larger field of view when high-frequency vertical
resolution is not critical.
