Abstract: A luminance determining unit determines a luminance distribution of an exterior circumstantial image in a line-of-sight direction of a driver, and a luminance changing unit determines a bright region of this luminance distribution. Further, the luminance changing unit determines a luminance after the change in a peripheral region of this bright region. A virtual-image creating unit creates a virtual image based on the determined luminance, and a display processing unit displays this virtual image on a display unit. In this manner, since a display system displays the virtual image for use in increasing the luminance in periphery of the bright region, the feeling of the brightness for the driver can be moderated, and therefore, the visual recognition can be improved. That is, the display system can output the virtual image depending on the circumstances.

Abstract: The present disclosure provides an image calibration method capable of easily calibrating a camera with a wide-angle of view which captures an image through a windshield. A calibration image is acquired by imaging, by a camera, a calibration object having a linear portion extending in one direction intersecting an optical axis of the camera through a windshield (step S1). A linear portion image corresponding to the linear portion is extracted from the calibration image (step S2). Distortion of the calibration image is corrected based on the linear portion image and the virtual linear portion image assumed in a case where the linear portion is imaged without through the windshield by the camera (step S3).
