Abstract: A camera system includes a detection unit that detects fitting errors of a camera as displacement quantities in a first direction, a second direction and an optical axis rotating direction of an image picked up by the camera, a selection unit that selects a rotation correcting quantity corresponding to the displacement quantity in the optical axis rotating direction from plural rotation correction maps prepared in advance, a computation unit that computes the correcting quantities in the first direction and the second direction respectively based on the detected displacement quantities in the first direction and the second direction using linear equations; and a correction unit that corrects the displacements in the first direction, the second direction and the optical axis rotating direction of the picked up image based on the selected rotation correcting quantity and the computed correcting quantities in the first direction and the second direction.

Abstract: When an image processing device subjects images photographed by on-vehicle cameras to viewpoint changing, and joints the images to form a top view image, and superposes boundary indicators at joints of the top view image to display it as an image with boundary regions to be monitored in a display, the boundary regions, or at least partial areas thereof, of the top view image are changed in appearance until a passage of predetermined time after predetermined conditions are established. Thus, the boundary regions can be made conspicuous only when necessary to be presented to an occupant of a vehicle, and an easily seen top view image can be displayed while preventing a reduction in effectiveness of warning of the boundary regions.

Abstract: An image processing system for a vehicle including a plurality of image pickup devices directed toward different predetermined areas around the vehicle to provide captured images and a display unit. Subject areas are extracted from the captured images, wherein the subject areas correspond to partial areas of predetermined areas captured by the image pickup devices that are adjacent to the image pickup devices. Brightness values of the subject areas are equalized to provide processed images, and the processed image are combined to generate a display image.

Abstract: When an image processing device subjects images photographed by on-vehicle cameras to viewpoint changing, and joints the images to form a top view image, and superposes masks on joints of the top view image to display it as an image to be monitored in a display, the masks of the top view image are highlighted until a passage of predetermined time after predetermined conditions are established. Thus, the masks can be made conspicuous only when necessary to be presented to an occupant of a vehicle, and an easily seen top view image can be displayed while preventing a reduction in effectiveness of warning of the masks.

Abstract: To display road situations on front left and front right sides of a vehicle, and so on without fail as a camera video image in an interior of the vehicle. In the case that a running speed of the vehicle is changed along an almost U-shaped line I as indicated by arrows, an image picked up by a vehicle-equipped camera is displayed on a monitor screen in the interior at a display starting speed Vd or less (an arrow B) and display of the monitor screen is executed surely at a speed Vmin or less (an arrow F) during the deceleration, while the display of the monitor screen is stopped at a non-displaying speed Vu or more (an arrow C) and the display of the monitor screen is stopped surely at a speed Vmax or more (an arrow E) during the acceleration.
