Abstract
PURPOSE: To obtain the identification result which is identical to that obtained through the human eyes for the colored pictures by utilizing the colors and the positional relation.
CONSTITUTION: For the input picture, the 3-dimensional histogram is produced based on the luminosity and chromaticity and then divided into regions of different luminosities. And the comparison is given among the threshold levels designated to each region, and the region featuring the highest level is extracted for leveling. And then the extraction control process is carried out to detect the adjacency to the region in the immediately preceding process part space, and then the picture element of the picture corresponding to the process part space is extracted to carry out the leveling process. These processes are carried out from the space of low luminosity to those of higher luminosity in sequence, and at the same time the extraction results are piled on to each other. When such extraction and leveling complete, the extraction result is read out of picture memory 1024 and then undergoes the expansion process through expansion process unit 1025 to be then applied to picture memory 1028. The contents of memory 1028 is transferred to memory 1024 to repeat the expansion process.
