Patent ID: 8624977

Claim:
A vehicle-peripheral image displaying system comprising: a vehicle-mounted external camera mounted on a vehicle and configured to shoot an image of a vehicle-periphery; a monitor provided in a vehicle interior at a position to cause the monitor to be visible for a driver; and a monitor-image producing unit configured to produce an image to be displayed on the monitor based on an actually shot camera image input from the vehicle-mounted external camera, wherein: the monitor-image producing unit includes: an image processor configured to perform a viewpoint conversion of the actually shot camera image input from the vehicle-mounted external camera into a virtual camera image which is to be converted as if it is viewed from the driver's eye position; an image memory configured to store a vehicle interior image, being previously shot from the driver's eye position, as a vehicle interior image; and an image composition circuit configured: to make the vehicle interior image output from the image memory translucent to form a translucent vehicle interior image, to perform an image composition such that the translucent vehicle interior image is superimposed on the virtual camera image output from the image processor, to produce a composite image representing the virtual camera image transparently through the translucent vehicle interior image, wherein: the image composition circuit displays, of an entire area of the vehicle interior image being previously shot from the driver's eye position, an area in which dimensions and a form of the vehicle are vertically projected on a road surface as a shadow, and the image composition circuit includes a blending circuit configured to set, of the vehicle interior image, the shadow area in which the vehicle is projected on the road surface as an opaque part having a transmissivity of 0% of the vehicle interior image, and set an area corresponding to a window glass of the vehicle as a transparent part having a transmissivity of 100% of the vehicle interior image, also set areas other than the shadow and the window glass as a translucent part having an arbitrary transmissivity.
