Abstract

To accurately determine whether there is a sharp change in a frame. Provided is an image processing device including: a histogram generating unit configured to generate a previous histogram showing a distribution of pixel values in a previous frame that is generated before a predetermined frame and a current histogram showing a distribution of pixel values in the predetermined frame; a normalizing unit configured to perform normalization to match variations of the pixel values of the previous histogram and the current histogram; and a similarity determining unit configured to acquire a degree of similarity of shapes of the previous histogram and the current histogram after the normalization and determine whether the degree of similarity is greater than a predetermined similarity determining threshold value.
