ONBOARD INFORMATION DISPLAY DEVICE AND ONBOARD INFORMATION DISPLAY METHOD

摘要

PPROBLEM TO BE SOLVED: To provide an onboard information display device and an onboard information display method that allow a driver to surely grasp the presence of other vehicles behind its own vehicle or existing posterolaterally and the direction and distance of the other vehicles in a short time. PSOLUTION: When a backward/posterolateral monitoring apparatus 1 detects the distance and the direction of the other vehicles existing behind its own vehicle and a display pattern is displayed on a peripheral vision part of the driver, an image control section 2 determines a display position of the display pattern in the horizontal direction on the basis of the direction of the other vehicles with respect to its own vehicle and determines the size of the display pattern on the basis of the distance of the other vehicles with respect to its own vehicle. The image control section 2 generates a low spatial frequency image with the determined size of the display pattern and resulting from eliminating spatial frequency components at which the luminance contrast sensitivity of the driver is obtained by the center vision only and displays the low spatial frequency image at the display position of the display pattern in the horizontal direction.
