ABSTRACT:
A memory device and an image processing apparatus able to achieve an increase in speed of a region growing algorithm which conventionally involved a long processing time and thereby enabling real time operation, including a memory array comprised of a matrix of a plurality of memory units each having two memory cells adjacent to each other in the same row, one flag cell, and two transfer gates for transferring flag data of the flag cell to the flag cells of the memory units adjacent in a row direction and a column direction in accordance with the stored data of each memory cell and including a region growing circuit for writing correlation data as results of operation of correlation of adjacent pixels into all memory cells, starting the region growing processing from a designated position (address) to extract an object, and outputting the same to an image combining unit.
