Abstract: A distance measuring device 1 includes a light emitting unit 11 that irradiates a subject with irradiation light, a light receiving unit 12 that receives reflected light from the subject, a distance calculating unit 14 that calculates a distance to the subject from an output signal of the light receiving unit, and an image processing unit 15 that generates a distance image of the subject from the calculated distance. The image processing unit 15 executes image processing within a period when the light emitting unit 11 stops the light emission and stops the image processing during a period when the light emitting unit 11 emits the light. When the image processing unit 15 stops the image processing, a clock frequency of an integrated circuit constituting the image processing unit 15 is further reduced as compared with an image processing time.

Abstract: A power transmission and reception system device includes: a first device including an outer surface on which a first image is represented; and a second device including an outer surface on which a second image is represented, the second device being placed on the first device. One of the first device and the second device is a power transmission device including a power transmission unit, and the other is a power reception device including a power reception unit. In a case where the power transmission device and the power reception device are positioned such that the first image and the second image are aligned, power can be fed such that a received voltage is greater than or equal to a predetermined value at the time of transmitting power to the power reception unit from the power transmission unit.

Abstract: An object position detection apparatus 1 includes a distance image generation unit 10 which generates a two-dimensional distance image by measuring a distance to a subject including an object on the basis of a light transmission time, an object image generation unit 16 which generates an object image in which the object is extracted from the distance image of the subject, and an installation angle detection unit 20 which detects an installation angle of the distance image generation unit 10. The object image generation unit 16 includes a differentiator 17 which performs a process of removing a background other than the object from the distance image of the subject and a threshold value d for removing the background in the differentiator 17 is set in response to the installation angle of the distance image generation unit 10 detected by the installation angle detection unit 20.

Abstract: A distance measurement apparatus 1 includes: a TOF camera 10 having a light-emitting unit 11, a light-receiving unit 12, and a distance-calculating unit 13 to measure a distance to the subject on the basis of light transmission time; and an image processing unit 17 that creates a distance image of the subject from distance data measured by the TOF camera 10. The image processing unit 17 determines whether or not there is a detection target in the created distance image. If there is no detection target in the distance image, the light emission intensity control unit 18 decreases the emitted light intensity from the light source of the light-emitting unit 11, and the operation mode is switched to a power saving mode in which the pixel addition control unit 19 increases an addition ratio of a neighboring pixel signal of the light-receiving unit 12.
