VEHICLE PERIPHERY MONITORING DEVICE AND VEHICLE PERIPHERY IMAGE DISPLAY METHOD
First Claim
1. A vehicle periphery monitoring device comprising:
- a plurality of imaging units mounted on a vehicle and configured to capture images of a vehicle periphery;
an image brightness calculation unit configured to calculate a value corresponding to brightness of an image taken by any one of the plurality of imaging units, from the image taken by the one of the imaging units,a brightness correction unit configured to correct brightness of the images obtained by the plurality of imaging units on the basis of the value calculated by the image brightness calculation unit,an image transformation unit configured to perform a predetermined coordinate transformation process on the image with the brightness thereof corrected by the brightness correction unit,an image combining unit configured to combine the plurality of images after the coordinate transformation process into a single image, andan image display unit configured to simultaneously display the composite image obtained by the image combining unit and the image taken by the one of the imaging units.

Abstract
From a plurality of imaging units (110) which capture images of a vehicle periphery and from an image taken by any one of the plurality of imaging units (any one of 111, 121, 131, 141), a value corresponding to brightness of the image is calculated. Based on the calculated value, brightness of images obtained by the plurality of imaging units (110) is corrected by a brightness correction unit (120). After a predetermined coordinate transformation is performed on the brightness corrected images, the images are combined into a single image, and the single image is displayed together with the image taken by the one imaging unit (any one of 111, 121, 131, 141).
