Image processing apparatus and computer-readable storage medium

摘要

According to one embodiment, an image processing apparatus includes a dividing unit, a calculating unit, a determining unit, and an output unit. The dividing unit is configured to divide an image into a plurality of regions. The calculating unit is configured to calculate a standard deviation and an entropy per region divided by the dividing unit based on tone information of pixels comprising each region, and calculate a ratio between the standard deviation and the entropy. The determining unit is configured to determine a region in which the ratio exceeds a reference value. The output unit is configured to output information based on a determination result obtained by the determining unit.
