An image of an area ahead of a vehicle is acquired by a camera provided in the vehicle. A traveling speed of the vehicle is acquired. An exposure area in the acquired image is set by a setting section, in which the exposure area is used for exposure control of the camera. By a calculating section, a control value for performing the exposure control is calculated based on pixel values of pixels included in the exposure area. The setting section changes a size of the exposure area based on the traveling speed, such that, when the traveling speed is a first speed, the size of the exposure area in the acquired image is smaller compared to that when the traveling speed is a second speed that is lower than the first speed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Control of exposure of camera","description":"A device for controlling exposure of a camera is provided.
