摘要: An edge map creation unit detects an intensity of input image in units three types blocks having different sizes. operation parameter adjustment sets initial values reference value and extraction on the basis a dynamic range which is difference between maximum minimum intensity. point extracts from value. Until amount determination determines that appropriate value, repeatedly performs processing adjusting extracting adjusted
