A low cost system for efficiently doubling the data readout rate from a high resolution CCD video sensor having two line outputs includes a pair of analog to digital converters, a separate pair of first-in first-out line stores for each of the analog to digital converters, and a digital to analog converter. Successive lines from the video sensor are fed into alternate ones of the analog to digital converters in sequence at the normal pixel clock frequency used with other than high resolution sensors. The contents of successive lines in each of the analog to digital converters are written into alternate ones of its respective pair of line stores in sequence. The contents of successive lines from all of the line stores are fed into the digital to analog converter. Finally, analog data is read out of the digital to analog converter to the single analog input of a high resolution video monitor at twice the pixel clock frequency. The entire system is made up of off-the-shelf components which are compact and relatively inexpensive.
A system for increasing the data readout rate from a high resolution CCD video sensor by a factor of n, where n is an integer greater than one and said video sensor produces a sequence of frames, each frame comprising a multiplicity of lines of pixels, said system comprising:
