Cameras are defined of a certain resolution according to the image sensor while often a certain region maybe of an interest to the user. The partial scan mode provides the function to provide output of a certain region of interest (ROI) which may have advantage in data transfer speed resulting faster operation. As described in binning mode speed gain would occur only in vertical resolution decrease. Partial Scan is supported only in Format 7 by setting the following registers described in the IIDC1.31 specification. Unit size of the partial scan is described in the camera specification which user must consider in increment configuration.
