A compact perception device for an autonomous driving system is disclosed. The compact perception device includes a lens configured to collect both visible light and near infrared (NIR) light to obtain collected light including collected visible light and collected NIR light. The device further includes a first optical reflector optically coupled to the lens. The first optical reflector is configured to reflect one of the collected visible light or the collected NIR light, and pass the collected light that is not reflected by the first optical reflector. The device further includes an image sensor configured to detect the collected visible light directed by the first optical reflector to form image data; and a depth sensor configured to detect the collected NIR light directed by the first optical reflector to form depth data.

A control unit of an imaging device includes a switching unit that switches between a first process that generates the visible light image from the output signals of the R pixels, the G pixels and the B pixels, and generates a first infrared light image from the output signals of the IR pixels, and a second process that causes the imaging unit to execute imaging in a first state. The infrared light emitting unit emits infrared light and a second state wherein the infrared light emitting unit does not emit infrared light, to generate the second infrared light image from the output signals of the IR pixels in the first state and from the difference values ΔR, ΔG and ΔB between the respective output signals of the R pixels, G pixels, and B pixels in the first state and the respective R pixels, G pixels and B pixels in the second state.
