DISPLAY DEVICE, ELECTRONIC APPARATUS, AND METHOD FOR DRIVING DISPLAY DEVICE

摘要

According to an aspect, a display device includes a signal processing unit that converts an input value of a input HSV color space of an input signal into an extension value of an extended HSV color space extended with a first color, a second color, a third color, and a fourth color to generate an output signal; performs peaking processing for analyzing the input signal of the imaged image to detect a focusing region; and determines whether to perform display in a peaking mode for highlighting the focusing region. When it is determined to perform display in the peaking mode, the signal processing unit increases a value of the output signal of the fourth color of a pixel in an outer edge of the focusing region.

主权项

1. A display device that displays an imaged image, the display device comprising:
an image display panel in which pixels are arranged in a two-dimensional matrix, each of the pixels including a first sub-pixel that displays a first color, a second sub-pixel that displays a second color, a third sub-pixel that displays a third color, and a fourth sub-pixel that displays a fourth color; and a signal processing unit that converts an input value of an input HSV color space of an input signal into an extension value of an extended HSV color space extended with the first color, the second color, the third color, and the fourth color to generate an output signal, and outputs the output signal to the image display panel, wherein the signal processing unit comprises:
an image processing unit that converts the input value of the input HSV color space of the input signal into the extension value of the extended HSV color space extended with the first color, the second color, the third color, and the fourth color, to generate the output signal;an image processing unit that performs peaking processing for analyzing the input signal of the imaged image to detect a focusing region in which a subject exists at a focal position; anda mode determination unit that determines whether to perform display in a peaking mode for highlighting the focusing region, and when the mode determination unit determines to perform display in the peaking mode, the signal processing unit increases a value of the output signal of the fourth color of a pixel in an outer edge of the focusing region.
