Abstract: A sensing device includes a light source, a light-receiving device including at least one light-receiving element that performs photoelectric conversion, and a processing circuit that controls the light source and the light-receiving device. The processing circuit causes the light source to emit light to a scene at least once, causes the light-receiving device to receive reflected light in each of a plurality of exposure periods, the reflected light being resulting from the emitted light, generates, based on received-light data from the light-receiving device, luminance data that indicates distributions of amounts of reflected light corresponding to the respective exposure periods and that are used for generating distance data for the scene, and outputs the luminance data and timing data indicating timings of the respective exposure periods.

Abstract: A video transmission method according to the present disclosure includes: generating a transmission signal including, in a time series, first video data having a first luminance dynamic range and second video data having a second luminance dynamic range wider than the first luminance dynamic range; and transmitting the transmission signal generated. In the generating of the transmission signal, a signal level corresponding to a luminance value is limited to a value lower than a limit value that is predetermined, in a transition period provided for switching from one of the first video data and the second video data to the other.
