ABSTRACT:
The present invention provides an image processing apparatus which acquires an image of quality desired for an object located in a biological body; sets up exposure values of a plurality of stages for an image pickup means; extracts the contour of an object in image signals output from the image pickup means; for the respective stages, generates first histograms for image signals before extraction and second histograms for image signals after extraction with a criterion representing the broadening of the distribution in the histograms set constant; calculates the amount of the kurtosis change between the first histograms and the second histograms; and selects, of the image signals after the extraction corresponding to the respective stages, an image signal after the extraction corresponding to one of the stages in which the amount of change is larger than a predetermined amount as an optimum image for an object.
