Abstract

Disclesed herein is a method of compensating a signal of an image of one screen for distortions in the horizontal and / or vertical directions of a screen of the image. The method includes the steps of: dividing one screen area of the image into a plurality of picture divisions; and detecting a movement vector of the image for each particular one of the picture divisions from information on a difference in image between the particular picture division on one of two screens and the particular division on the other of the two screens. The method further includes the steps of: finding a difference in the detected movement vector between any specific picture division and a picture division adjacent to the specific picture division in order to detect a velocity of a change in image distortion for the specific picture division; and compensating the image for a distortion for each of the picture divisions on the basis of a velocity detected for each of the picture divisions as the velocity of a change in image distortion.

Description

[0001] Cross References to Related Applications [0002] The present invention contains subject matter related to Japanese Patent Application JP2006-024065 filed in the Japan Patent Office on Feb. 1, 2006, the entire content of which is hereby incorporated by reference. technical field [0003] The present invention relates to a method for compensating an imager-created image for distortions arising in the imager-created image, such as in the process of taking a picture of a subject using an image taking device The invention also relates to means for compensating for such distortions in images produced by an imager. More specifically, the present invention is applicable to a photographing device employing an X-Y addressing solid-state image pickup device such as a CMOS (Complementary Metal Oxide Semiconductor) solid-state image pickup device and a recording / reproducing device having a photographing function. Examples of photographing devices employing X-Y addressing solid-sta...
