A photodetector of the present disclosure includes multiple pixels including a light receiving element, and a sampling circuit that is provided corresponding to the multiple pixels, and samples light reception data output from the pixel on the basis of multiple clock signals having different phases, in synchronization with input of a trigger signal. The sampling circuit switches the phase of the clock signal every time a trigger signal is input. Additionally, a distance measuring device of the present disclosure includes a light source that irradiates an object to be measured with light and a photodetector that detects light reflected by the object to be measured. As the photodetector, a photodetector having the above configuration is used.

Photodetector, driving method of photodetector, and distance measuring device

A pixel is appropriately interpolated regarding a histogram image in which a distance histogram is allocated to each pixel position. A signal processing apparatus according to the present technology includes a histogram generation unit that inputs a histogram image in which a distance histogram indicating results of a plurality of times of distance measurement as frequency information for each distance is allocated to each pixel position and generates a distance histogram of an interpolation target position in the histogram image on the basis of distance histograms of a plurality of pixel positions near the interpolation target position.

Signal processing apparatus and signal processing method

The present technology relates to a distance measuring device and a distance measuring method that can improve the accuracy of distance measurement. A control unit controls a light emitting operation by supplying a light emitting unit with a light emission timing signal for controlling the light emitting operation for emitting irradiation light and controls the light receiving operation by supplying a light receiving unit with a light reception timing signal for controlling the light receiving operation for receiving reflected light. A measuring unit measures a deviation time between the light emission timing at which the light emitting unit emits the irradiation light and the light reception timing at which the light receiving unit receives the reflected light, using the light emission timing signal and the light reception timing signal. The present technology can be applied, for example, to a case where distance measurement is performed by using the ToF method.
