Abstract
An aspect of the present invention is a processor for an electronic endoscope that acquires a captured image of a living tissue and performs enhancement processing. The processor includes: a region detection unit configured to detect an enhancement processing target region in the captured image from pixel information of the captured image of the living tissue; and an enhancement processing unit configured to perform enhancement processing on the enhancement processing target region detected by the region detection unit. The region detection unit detects the enhancement processing target region based on a difference in signal level between a pixel of interest in the captured image and a pixel surrounding the pixel of interest, and the enhancement processing unit performs enhancement processing on the enhancement processing target region such that enhancement is weakened as the difference in signal level is larger and enhancement is strengthened as luminance is higher.
