Abstract: According to an aspect, an imaging display system includes an imaging device, a display device, and a processing device. The imaging device includes a rolling shutter image sensor that takes an image. The display device displays the image. The processing device performs image processing on the image. The imaging display system is mounted on a movable body that moves in a certain direction on a reference plane. The imaging device is arranged at an angle with respect to a moving direction of the movable body on the reference plane. An imaging scanning direction of the image on the image sensor is horizontal with respect to the reference plane. A display scanning direction of the image displayed on the display device coincides with the imaging scanning direction.

Abstract: According to an aspect, a display device includes an image display panel and a signal processing unit. The signal processing unit derives a generation signal for a fourth sub-pixel in each of pixels based on an input signal for a first sub-pixel, an input signal for a second sub-pixel, an input signal for a third sub-pixel, and an extension coefficient. The signal processing unit derives a correction value based on a hue of an input color corresponding to a color to be displayed based on the input signal for the first sub-pixel, the input signal for the second sub-pixel, and the input signal for the third sub-pixel. The signal processing unit derives the output signal for the fourth sub-pixel in each of the pixels based on the generation signal for the fourth sub-pixel and the correction value and outputs the output signal to the fourth sub-pixel.
