Abstract: A signal processing device includes a converter and a selector. The converter converts an input video signal into the output video signal for the low-brightness display device. The selector selects one of the input video signal and the output video signal, and outputs the selected video signal to the display device. The selector selects the output video signal in a case where a high-brightness flag indicating a video signal for the high-brightness display device is added to the input video signal, and where information indicating that the display device is the low-brightness display device is acquired or information indicating that the display device is the high-brightness display device is not acquired, and selects the input video signal in a case where the high-brightness flag is not added to the input video signal.

Abstract: A stereoscopic display device for displaying left-eye and right-eye images in alternation on a display to show the images as a stereoscopic image.

Abstract: Attempts to achieve a higher resolution and a higher frame rate of a distance image when a distance to an object within a target space is estimated using the TOF method would cause CCD saturation due to shot noise or environment light, and lower distance precision. A distance estimation apparatus illuminates an object with illumination light for distance estimation emitted from a light source that can emit light (electromagnetic wave) having a predetermined illumination frequency, receives reflected light of the illumination light, obtains information about the distance from the apparatus to the object, generates distance image data based on the distance information, extracts edge information of a color image formed using a visible light component obtained in synchronization with the reflected light, and corrects distance information of a target part of the distance image using distance information of a neighboring part of the target part based on the edge information.

Abstract: A display device prevents the display screen from flickering even when the display mode changes automatically. The display device has plural modes, a viewing environment detector that detects the ambient brightness and changes the mode based on the detected ambient brightness, a screen brightness calculator that calculates the brightness of the display screen in each mode based on the average brightness of video data in one frame, and a screen brightness merger that, when the mode changes, gradually changes the brightness of the display screen from the brightness of the display screen before the mode change to the brightness of the display screen after the mode change.

Abstract: An image signal processing apparatus includes an output unit that outputs an image, a detection unit that detects that the output unit is outputting a 3D image, and a light modulation control unit that causes a light emitting apparatus to reduce luminance of a light emitting unit thereof, in response to the detection by the detection unit that the output unit is outputting a 3D image.

Abstract: Flicker occurs in a flicker-noticeable area consisting of pixels with no pixel value variations. An image processing device (100) includes a variance calculation unit (101) that obtains a variance of an area consisting of a target pixel and neighboring pixels included in a first frame, and changes, according to the variance, the rate at which an error generated at the target pixel through tone level restriction is distributed within the frame and between frames. The image processing device (100) includes an error diffusion unit (113) that distributes the error generated at the target pixel to the neighboring pixels included in the first frame based on an intra-frame error diffusion rate and an intra-frame error distribution weight, and distributes the error generated at the target pixel to a target pixel and neighboring pixels included in the second frame based on an inter-frame error diffusion rate and an inter-frame error distribution weight.

Abstract: Conventionally, there has been a danger that CCD saturation may occur because of the influence of the shot noise and the environment light if a higher resolution of a distance image showing the distance to an object present in a target space and a higher frame rate are achieved when the distance image is estimated by the TOF method, and the distance accuracy may degrade. An emission frequency selecting unit (7) receives light (S2) reflected from the object when a light source does not emit light and selects illumination light (S1) having an emission frequency insusceptible to the environment light according to the frequency analysis of the reflected light (S2). An image creating unit (6) selects a light source emitting the illumination light having the optimum emission frequency from among prepared light sources (9A to 9N), receives reflected light of the illumination light from the selected light source, and creates the distance image showing the distance to the object.
