Apparatus and method of processing image as well as apparatus and method of generating reproduction information with display position control using eye direction

摘要

An apparatus of processing an image contains a scene-change-detecting unit that detects a scene change of input image based on an image signal relative to the input image, a display-position-controlling unit that determines a display position of an image after the scene change to a display position associated with an image before the scene change based on a detection result in the scene-change-detecting unit, and a display-position-setting unit that sets the display position determined in the display-position-controlling unit as a display position in which the image after the scene change is displayed. The display-position-controlling unit detects a feature value of the images before and after the scene change and determines the display position of the image after the scene change based on the feature value of the images.

1. An apparatus of processing an image, the apparatus comprising: a scene-change-detecting unit that detects a scene change in an input video signal; a display-position-controlling unit that determines a display position of an image of the input video signal after the scene change in relation to a display position of an image of the input video signal before the scene change based on a detection result in the scene-change-detecting unit; and a display-position-setting unit that sets the display position determined in the display-position-controlling unit as a display position in which the image of the input video signal after the scene change is displayed, wherein the display-position-controlling unit detects an eye direction of a face region in the images of the input video signal before and after the scene change and determines the display position of the image of the input video signal after the scene change based on the eye direction of the face region in the images of the input video signal before and after the scene change, and wherein the display-position-controlling unit includes: a first face-region-extracting section that extracts the face region from the input video signal; a first eye-direction-detecting section that detects a first eye direction from the region of face image extracted in the first face-region-extracting section; a delay section that delays the input video signal to generate a delayed input video signal; a second face-region-extracting section that extracts a region of face image from the delayed input video signal received from the delay section; a second eye-direction-detecting section that detects a second direction of an eye direction from the region of face image extracted in the second face-region-extracting section; and a display-direction-deciding section that decides the display direction of the image of the input video signal after the scene change relative to the display position of the image of the input video signal before the scene change based on the first and second eye directions.
