PROBLEM TO BE SOLVED: To provide an image display device and method, suppressing color breaking in video tracking in a field sequential system. SOLUTION: A color component image with a relatively high luminance level is extracted as a fundamental image from an input image. A differential image is obtained by subtracting color component of the fundamental image from an input image, and is decomposed into a plurality of color components. The differential image for each color component is divided into two so that a signal value is reduced to substantially half. The differential images for each color component divided into two and the fundamental image are selectively output on a display section as a plurality of field images. The output order is controlled so that the fundamental image is displayed at a middle timing of a frame period. The half-divided differential images are displayed at timings before and after the middle timing for the fundamental image so that the half-divided differential image with higher luminance level with consideration for visibility characteristic is displayed at a timing closer to the middle timing for the fundamental image.

PROBLEM TO BE SOLVED: To prevent the insufficiency of luminance using a backlight. SOLUTION: A necessary light emission level calculation unit 101 calculates a necessary target block light emission level of a target block of the backlight, which satisfies a necessary luminance based on an image signal. When a maximum light emission level in which the target block of the backlight can emit light is insufficient, a first neighboring block light emission level calculation unit 103 calculates a light emission level of a first neighboring block compensating the insufficient luminance and neighboring the target block, which compensates the lack of necessary luminance by an amount of light emission contribution to the target block of light emission of the first neighboring block. The target block of the backlight is caused to emit light in the maximum possible light emission level, and the first neighboring block of the backlight is caused to emit light in the first neighboring block light emission level. The present invention may be applied to an image processing apparatus like a liquid crystal display. COPYRIGHT: (C)2010,JPO&INPIT

PROBLEM TO BE SOLVED: To correct blur in an image while details of the image are retained. SOLUTION: An image captured using an imaging unit 14 of a camera 11 is subjected to gamma processing using a gamma processing unit 15 so that an image is obtained. Thereafter, the image is supplied to the inverse gamma processing unit 22. The inverse gamma processing unit 22 performs inverse gamma processing to the image supplied from the gamma processing unit 15 so that the image has characteristics the same as those of the image, which is the same as the original image before it is subjected to the gamma processing using the gamma processing unit 15. The correction processing unit 23 performs correction processing to the image, which is subjected to the inverse gamma processing using the inverse gamma processing unit 22, so that the image including blur is corrected. The gamma processing unit 24 performs gamma processing, which is the same as that performed using the gamma processing unit 15, to the image, which is subjected to the correction processing and thereafter, the processed image is supplied to a display unit 13. This invention can be applied to a TV receiver. COPYRIGHT: (C)2008,JPO&INPIT

Abstract:
PROBLEM TO BE SOLVED: To make it possible to easily detect a motion vector taking harmony with the ambient. SOLUTION: A histogram part 35 determines a motion vector candidate with the highest frequency out of motion vector candidates in an attention pixel and respective surrounding pixels supplied from a template matching part 34 as a motion vector in the attention pixel, and supplies it to a motion vector correction part 36. The motion vector correction part 36 evaluates reliability of the motion vector supplied from the histogram part 35 based on a luminance slope of surrounding pixels of the attention pixel detected by the luminance slope detection part 33 and a control signal which is supplied from the template matching part 34, and orders to execute correction or not. If the unit evaluates that the reliability of the motion vector is low, the unit corrects the motion vector. COPYRIGHT: (C)2005,JPO&NCIPI
