Abstract: A processing device of a displacement detection device includes an AD conversion device, a switching circuit, and an arithmetic processing unit. The AD conversion device has first and second AD conversion units. The switching circuit periodically switches between a first connection mode in which a first differential signal is AD-converted by the first AD conversion unit and a second differential signal is AD-converted by the second AD conversion unit, and a second connection mode in which the first differential signal is AD-converted by the second AD conversion unit and the second differential signal is AD-converted by the first AD conversion unit. The arithmetic processing unit outputs displacement information of a scale based on an addition average value of the first differential signals output from the first and second AD conversion units and an addition average value of the second differential signals output from the first and second AD conversion units.

Abstract: In a detection system, an LED unit includes a plurality of LEDs, and each of the LEDs applies light toward a different part of an occupant's face in a vehicle. A position detection unit detects a position of a pupil in an occupant's eye on the basis of an image captured by an imaging unit. The LED unit applies light from LEDs with a light emission pattern selected from a plurality of predetermined light emission patterns. The light emission patterns differ from each other in the combination of the LEDs that emit light and the LEDs that do not emit light in the LEDs. An operation controller controls the LED unit to detect the position of the pupil by applying light from the LEDs that emit light with a light emission pattern different from a current light emission pattern when the position of the pupil cannot be detected.

When the signboard course information out of the signboard information is visually recognized continuously, a control device generates course information based on the signboard course information. The generated course information is output to a vehicle control ECU, and course change processing based on the course information is performed by the vehicle control ECU.
