Title:
REAR IMAGE PROCESSING DEVICE AND REAR IMAGE DISPLAY METHOD
Document Type and Number:
WIPO Patent Application WO/2020/079831
Kind Code:
A1
Abstract:
A rear image processing device (10) comprises: a rear image acquiring unit (11) which acquires a rear image which is an image depicting an environment to the rear of a vehicle; a distance acquiring unit (12) which acquires the distance from the vehicle to an object shown in the rear image; an image processing unit (13) which executes a screening process on the rear image; and a display processing unit (14) which displays the rear image after the screening process on a display device. The image processing unit (13), when the distance from the vehicle to the object is greater than a pre-determined threshold value, sets a screening coefficient to a fixed reference value and executes the screening process on the rear image, and, when the distance from the vehicle to the object is equal to or less than the threshold value, changes the screening coefficient such that the rear image reduces in size as the distance decreases, and executes the screening process on the rear image.
