Abstract

An object detection device includes: a light emitter that emits light; a sensor that generates a first pixel signal by exposure to reflected light according to a combination of emission by the light emitter and first exposure and a second pixel signal by exposure to reflected light according to a combination of the emission and second exposure; and a distance calculator that generates a distance image by ratio operation using the first pixel signal and the second pixel signal. Timing of the first exposure is set to timing during which the sensor is not exposed to reflected waves from an object included in a first section in which a distance from the object detection device is from 0 to a predetermined value. A time difference between the emission and the second exposure is greater than a time difference between the emission and the first exposure.
