20110115982 | VIDEO SIGNAL PROCESSING DEVICE AND VIDEO DISPLAY DEVICE - In an X-Y conversion chart, a threshold Th is defined as Y=0, that is, the threshold Th is defined on the X axis, a range from −Th to +Th is defined as a range in which smoothing (noise elimination) processing is performed, and a range outside the range from −Th to +Th is defined as a range in which sharpening processing is performed. As shown in equations in drawings, among equations denoted by Y | 05-19-2011 |
20110216967 | SPECIFIED COLOR AREA DEMARCATION CIRCUIT, DETECTION CIRCUIT, AND IMAGE PROCESSING APPARATUS USING SAME - A specified color area demarcation circuit | 09-08-2011 |
20120062622 | LUMINANCE CONTROL DEVICE, DISPLAY APPARATUS USING THE SAME, LUMINANCE CONTROL METHOD AND LUMINANCE CONTROL PROGRAM - Power consumption is cut down by reducing backlight light source luminance in accordance with the variability of luminance of the picture displayed on a display panel. A picture luminance detector calculates information (luminance information) representing luminance of the picture at intervals of a time unit. A picture luminance storage is a memory capable of storing the past records of luminance information within a fixed period of time (some seconds to some ten seconds). A processor is configured of a variation detector and a light source luminance determiner. Variation detector performs detection of the variability of picture luminance based on the luminance information on the current picture detected by picture luminance detector and the past records of picture luminance information stored in picture luminance storage to output variation information. Light source luminance determiner determines light source luminance based on the luminance information on the current picture detected by picture luminance detector and the variation information output from variation detector and outputs a light source information control signal. | 03-15-2012 |

20130004062 | COLOR JUDGING APPARATUS, COLOR JUDGING METHOD, IMAGE PROCESSING CIRCUIT AND PROGRAM - With a pixel included in image data as a reference pixel, a pixel that shares the same pixel value as the reference pixel or a pixel similar to the reference pixel is judged as a shared pixel, and for the pixel judged as the shared pixel, color of the reference pixel is regarded as a color judgment result of the shared pixel, thus making it possible to reduce color calculation processing for the shared pixel. This makes it possible to provide a color judging apparatus operating at higher speed and the like. Thereby, it is possible to provide the color judging apparatus operable at high speed and the like by reducing the number of times of the color calculation processing executed for an input image. | 01-03-2013 |

20150054780 | OPERATION INPUT DEVICE, OPERATION INPUT METHOD, AND PROGRAM - A touch pad outputs a detection signal indicating a coordinate corresponding to a contact state where a finger is in contact with the coordinate detecting unit, and a detection signal indicating a coordinate corresponding to a proximity state where the finger is in proximity to, without contact with, the coordinate detecting unit. An operation input device detects, based on the detection signals, a contact region in which the finger is in contact with the coordinate detecting unit, and a proximity region in which the finger is in proximity to, without contact with, the coordinate detecting unit. Then, the operation input device determines a pointed coordinate based on the contact region detected and the proximity region detected. | 02-26-2015 |
