ABSTRACT:
Apparatus and method for controlling a high resolution charge coupled device (CCD) image sensor operate in accordance with a television standard to provide horizontal, vertical, and other CCD control signals to obtain a purely sequential high resolution mode of operation on the one hand. Alternatively, there is a modified mode of operation which provides interlaced even and odd groups of video signals to be viewed directly on a television viewfinder display. The apparatus includes a frequency generator, a standard timing generator, a pixel clock generator, and a small number of additional timers and logic units which are driven by signals from the generators to selectably generate the vertical, horizontal, and other CCD control signals for the alternate modes of operation. The method includes generating a plurality of precisely timed pulses referenced to television standard synchronizing and control signals, and logically combining these pulses and standard signals to generate vertical, horizontal, and other CCD control signals.
