data in the system of the invention shown in fig3 a video camera 50 detects a scene to be processed the analog to digital converter 41 converts each cd pixel to digital representation which is stored in vam 43 the vam 43 is provided with multiple input and output ports for storing and sending out digital data independent of flag and signal lines the vam should be initialized prior to use that is each cell set to zero each vam addressable location or cell is made up of a plurality of stages the vam architecture is shown in fig4 and contains several structures in the cell including the memory in this simplified form of the invention the detected scene is represented in black and white whereas the analog signal values stored in the ccd represents the luminosity of the corresponding pixels in the scene the preferred embodiment of a single random access memory cell is shown in fig4 has seven structures or stages capable of functioning as registers 21 through 27 each cell contains a digital storage location corresponding to each pixel of the detected scene the memory portion is referred to as register a 21 and thus corresponds to a pixel in the scene being.
