Vehicle rear monitoring system

Abstract

A vehicle rear monitoring system ( 1 ) includes a camera ( 40 ) that captures an image of an area to a rear of a vehicle, and a processing unit ( 10 ) that processes the image captured by the camera. The processing unit ( 10 ) creates a first vehicle rear image that is displayed in a first display area ( 22 A) that is a portion of a display area of a display device, when traveling forward, and creates a second vehicle rear image that is displayed in a second display area ( 22 ) that is within the display area of the display device and that is an area that includes the first display area and is larger than the first display area, when traveling backward.

1 .- 8 . (canceled) 
     
     
         9 . A vehicle rear monitoring system comprising:
 a camera that captures an image of an area to a rear of a vehicle and outputs the captured image;   a processing unit that processes the captured image, and creates a vehicle rear image;   a display device that displays the vehicle rear image; and   a traveling direction detecting device that detects a traveling direction of the vehicle and notifies the processing unit of the detected traveling direction,   wherein the processing unit creates a first vehicle rear image that is the vehicle rear image that is displayed in a first display area that is a portion of a display area of the display device, when the traveling direction is forward, and creates a second vehicle rear image that is the vehicle rear image that is displayed in a second display area that is within the display area of the display device and that is an area that includes the first display area and is larger than the first display area, when the traveling direction is backward.   
     
     
         10 . The vehicle rear monitoring system according to  claim 9 , wherein the processing unit creates the vehicle rear image by cropping the captured image, and a cropped area when the traveling direction is backward is larger than the cropped area when the traveling direction is forward. 
     
     
         11 . The vehicle rear monitoring system according to  claim 9 , wherein the second vehicle rear image is an image captured at the same focal length as the first vehicle rear image. 
     
     
         12 . The vehicle rear monitoring system according to  claim 9 , wherein the processing unit continuously changes an outer frame of a display area of the vehicle rear image by animation display when a change in the traveling direction is detected. 
     
     
         13 . The vehicle rear monitoring system according to  claim 12 , wherein the traveling direction detecting device is a shift lever, and detects a change in the traveling direction according to whether the shift lever has been shifted into reverse. 
     
     
         14 . The vehicle rear monitoring system according to  claim 9 , wherein the second display area is the entire display area of the display device. 
     
     
         15 . The vehicle rear monitoring system according to  claim 9 , wherein the processing unit places an area except for the first display area of the second display area in a display state of a solid dark color when the traveling direction is forward. 
     
     
         16 . The vehicle rear monitoring system according to  claim 9 , wherein the processing unit creates the vehicle rear image such that an object included in the first vehicle rear image and the second vehicle rear image is the same size and in the same positional relationship when a change in the traveling direction of the vehicle is detected.
