摘要： When gradation of a mixed video signal is equal to or less than a predetermined gradation, a subframe data generator generates subframe data so that an applied voltage to a display element is turned off during a first predetermined period from a start of the frame of a video signal for a visible light image or a video signal for an infrared light image. A light source controller turns on a visible light source after a lapse of a second predetermined period from a start of the frame of the video signal for a visible light image, and turns off the visible light source at the timing when the frame of the video signal for a visible light image is ended.

摘要： A display device includes a display pixel unit and a signal processing unit. The display pixel unit includes a plurality of pixels arranged in a horizontal direction and a vertical direction. The signal processing unit determines a correction value corresponding to a target pixel based on differences between gradation data of the target pixel and gradation data of peripheral pixels disposed in the horizontal direction, the vertical direction, and an oblique direction with respect to the target pixel, respectively, among the plurality of pixels, increases or decreases a pixel value of the target pixel based on the correction value, and corrects the gradation data of the target pixel to reduce the differences.

摘要： A signal processor converts an input 3D image signal into a signal in which a left-eye signal and right-eye signal are rearranged temporally alternately. A driver of a liquid crystal display element includes a sub-frame data generator configuring all the sub-frames with step bit pulses and generating sub-frame data by using a drive gradation table in which the last sub-frame reaches a drive state when a drive gradation is “1” and the number of sub-frames reaching the drive state is increased one by one toward ahead of a sub-frame which has already reached the drive state, every time the drive gradation is increased by one. The liquid crystal display element is driven by the driver. An illumination optical system causes illumination light to enter into the liquid crystal display element. A projection lens projects modulated light emitted from the liquid crystal display element.
