A time shared histogram chip (80) implemented in a system for manipulating video signal data. The system includes a processor (82) for controlling system operation and for processing a video signal input into the system. The time shared histogram chip (80) accumulates video signal data in a format readable by the processor (82). The histogram chip (80) is operative to perform histogramming, video line summing and video line grabbing functions. Control means (100) is operatively connected to the processor and enables the processor (82) to selectively control the mode of operation of the histogram chip (80).
