1. An imaging system wherein video data from each video frame of video data words is multiplexed serially by a row, including means for enhancing said video data by operating on successive kernels of said data words, comprising: a plurality of main processors and memories individually associated with said processors, each of said processors corresponding to an individually assigned block of video data words in said frame; a plurality of bus control means, individually associated with said processors, each one of said bus control means for selecting those data words from said video data words which lie within the corresponding assigned data word block; data bus means for simultaneously distributing each of said data words to said k bus control means; and a plurality of internal data bus means individually associated with said plurality of bus control means, each of said internal data bus means for carrying the selected ones of said data words from the corresponding bus control means to the corresponding one of said memories and for permitting the corresponding one of said processors to access data words in said corresponding memory, wherein each processor is programmed with selected operator means for generating an enhanced value from each kernel of data words stored in the corresponding memory.
