Image processing apparatus and image processing method for displaying a focused portion with emphasis on an image

摘要

There is provided an image processing apparatus including a focused area judgment unit that judges a focused area in target image data, a distribution information generation unit that generates distribution information of an edge evaluation value with the focused area judged by the focused area judgment unit as a target, a threshold value setting unit that variably sets a threshold value for judging an emphasis display portion using the distribution information generated by the distribution information generation unit, and a display data generation unit that selects an emphasis display portion in the image data using the threshold value set by the threshold value setting unit and generates display data for displaying the selected portion with emphasis.

1. An image processing apparatus, comprising:
a focused area judgment unit configured to judge a focused area in target image data; a distribution information generation unit configured to generate distribution information of an edge evaluation value with the focused area judged by the focused area judgment unit as a target, wherein the distribution information generation unit generates the distribution information of the edge evaluation value using a contrast differential obtained as a derivative value of a luminance between adjacent pixel data as the edge evaluation value; a threshold value setting unit configured to variably set a threshold value used for judging an emphasis display portion using the distribution information generated by the distribution information generation unit; and a display data generation unit configured to select an emphasis display portion in the image data using the threshold value set by the threshold value setting unit and generate display data for displaying the selected portion with emphasis.
