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.

A distance measuring device using a multiple wave enables measurement of long distances with a high resolution and with a high precision by significantly reducing the circuit scale required for demultiplexing circuitry. A distance measuring device () includes an illumination unit () that illuminates using multiple modulated light having a plurality of frequencies satisfying a relationship in which one frequency is an even multiple of another frequency, a light receiving unit () that accumulates the charge of reflected light of the multiple modulated light into a plurality of accumulation units while switching an accumulation unit into which the charge is accumulated at a predetermined timing, and a distance calculation unit () that calculates a distance based on the charge.

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.

Flicker occurs in a flicker-noticeable area consisting of pixels with no pixel value variations. An image processing device () includes a variance calculation unit () 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 () includes an error diffusion unit () 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.
