Abstract
A video imager which is read out in block format is compensated for fixed pattern noise and shading in a single, economical and efficient manner. In block readout, a plurality of rows of photosites are read out of the sensor simultaneously. According to the invention, a single noise compensation data is stored for each column of photosites in a block, thus reducing the number of compensation data which must be stored and consequently, the size of the memory needed. Additionally, a single set of compensation data for a block may be used for multiple frame rates or for several blocks in a frame, thereby further reducing the memory capacity for storing noise compensation data. The invention is useful in fast frame recorders operable at multiple frame rates.
