Abstract: According to one embodiment, a display device which includes a plurality of signal line drivers which drive a display area of a display panel by dividing the display area into a plurality of division display areas is provided. The plurality of signal line drivers include a master signal line driver and a slave signal line diver. Each of the master signal line driver and the slave signal line driver drives at least one of the division display areas. An outward path outputs a direct-current voltage from the master signal line driver to the slave signal line driver. A return path is electrically connected to and is contiguous with the outward path, and returns the direct-current voltage to the master signal line driver.

Abstract: Shown is a diagram showing input-output characteristics for color adjustment. The horizontal axis represents an input, and the vertical axis represents an output. In this color adjustment technique, first, so as to prevent degradation the luminance of white after white correction, correction coefficients are determined so that the smallest value thereof may be 1. Note that “1” here is not a strict value. To be more specific, in contrast to the conventional technique in which correction is performed with the largest value being made equal to about “1,” the present embodiments sets the smallest value at about “1.” This idea itself is a first point which makes the embodiments different from the conventional technique. When doing so, all the correction coefficients are “1” or larger. In the case where a correction coefficient is “1” or larger, when the input is large, the output is saturated.

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: 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.
