Abstract: 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.

Abstract: 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.

Abstract: An image processing device (100) includes: a luminance distribution information preparation section (110) for preparing a luminance histogram in which each luminance range serves as a class, by counting the number of pixels belonging to each luminance range; a weight correction section (120) for generating, for each luminance range, a weighting value which is proportional to a corresponding class value; and an image processing section (140) for correcting a luminance value of each pixel so that a difference between a maximum luminance value and a minimum luminance value in the luminance range is determined by an increasing function with respect to both (i) a frequency of the luminance range and (ii) a weighting value of the luminance range.

Abstract: In an X-Y conversion chart, a threshold Th is defined as Y=0, that is, defined on the X axis, a range from ?Th to +Th is defined as a range in which smoothing processing is performed, and a range outside ?Th to +Th is defined as a range in which sharpening processing is performed. Among equations denoted by Y1 and Y2 expressed by two linear straight lines, intersections of both the equations Y1 and Y2 are set to the maximum value and the minimum value of an X-Y conversion equation in this case. The threshold is expressed by an intersection of Y2 and the X axis. This algorithm is formed by three factors of: a coefficient ? indicating the strength of smoothing; a coefficient ? indicating the strength of sharpening; and a threshold Th on the X axis for determining switching between the smoothing processing and the sharpening processing.

Abstract: 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.

Abstract: A specified color area demarcation circuit 6 has a luminance information (histogram) acquisition unit 3 for multiple pixels and a luminance information (histogram) analysis unit 5 for the multiple pixels. The luminance information (histogram) acquisition unit 3 for the multiple pixels acquires luminance information of the multiple pixels in an input image. In order to acquire the luminance information of the multiple pixels, the luminance information (histogram) acquisition unit 3 creates, for example, a histogram of the luminance indicating frequencies. As an example of the histogram, 0 to 255 gray levels in an image are divided into thirty-two (0-7, 8-15, . . . 240-247, 247-255) ranges, and the number of pixels present in each of the divided gray levels (luminance Y) is counted.

Abstract: 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 Y1 and Y2 which are expressed by two linear straight lines, intersections of both the equations Y1 and Y2 are set to the maximum value and the minimum value of an X-Y conversion equation in this case. In addition, the threshold is expressed by an intersection of Y2 and the X axis. This conversion algorithm is formed by only three factors of: a coefficient ? indicating the strength of smoothing; a coefficient ? indicating the strength of sharpening; and a threshold Th on the X axis for determining switching between the smoothing processing and the sharpening processing.
