Image display control apparatus and method, and program for controlling image display control apparatus

摘要

An image within a search area of an image of interest is rotated from 0 to 345° in increments of 15°. An evaluation value of facial likeliness of an image after rotation thereof by each angular increment is calculated. A correction angle is calculated based upon a rotation angle (rotational manipulated variable θ) that affords the maximum evaluation value calculated. The image of interest is displayed upon being rotated based upon the correction angle calculated. Thus, the image of interest is displayed in an orientation suitable for appreciation.

主权项

1. An image display control apparatus comprising:
an in-area-image rotating device that is configured to scan a search area with a prescribed size on respective ones of a plurality of images of interest with different sizes, each of the plurality of images of interest with different sizes being obtained in such a manner that the size of an image of interest becomes gradually smaller and the image of interest diminishes to a prescribed minimum image size, and configured to rotate an in-area-image, which is located within the search area scanned on images of interest, contained in each image of interest, through a specified angle in prescribed angular increments; an evaluation-value calculating device configured to calculate an evaluation value, which represents facial likeliness of the in-area-image within the search area at each angle for each image of interest through which the in-area-image has been rotated in the prescribed angular increments by said in-area-image rotating device, using detection data for detecting a face image; a rotation correction angle deciding device configured to decide a rotation correction angle which displays the detected face image in a rectangle display window in upright, based upon an angle that affords a maximum value of the evaluation value representing facial likeliness at each angle for each image of interest by said evaluation-value calculating device; and a display control device configured to control a display unit, in such a manner that each image of interest is rotated and displayed in the rectangle display window, using the rotation correction angle decided by said rotation correction angle deciding device, thereby each image of interest in which the image of a person has been rendered upright is displayed on the rectangle display window.
