FAST FRAME RATE SENSOR READOUT ABSTRACT OF THE DISCLOSURE Prior art electronic cameras that use solid state area image sensors are generally limited to operation at frame rates less than about 120 frames per second. Such frames rates are limited, principally, by the maximum data rate at which solid state sensors may be operated. In a preferred embodiment wherein photosights of a sensor are arranged in rows and columns, the sensor is read out in "blocks" of photosite, with each block being comprised of a plurality of adjacent photosite rows. A block of photosites is enable by the application of an enablement signal to the photosites within the block; and a column address signal is sequentially applied to the photosite columns to effect column-wise readout of the photosite rows within the enabled block. The output signal so produced is, therefore, comprised of block information in a "serial" format, while the information content of each block is comprised of a plurality of line signals in a "parallel" format, such line signals corresponding to the individual photosite rows within that block.
