proprietary to OmniVision Technologies PRELIMINARY SPECIFICATION version 1.0
4.2 image windowing
An image windowing area is defined by four parameters, x_addr_start, x_addr_end, y_addr_start, y_addr_end. By
properly setting the parameters, any portion or size within the sensor array can be defined as an visible area. This
windowing is achieved by simply masking the pixels outside the defined window; thus, it will not affect the original timing.
