IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD
First Claim
1. An image processing device configured to be installed in a vehicle, comprising:
- an image acquirer configured to acquire camera images captured by cameras provided on the vehicle;
an image selector configured to select one of the camera images as a representative image based on luminances of the camera images;
a first luminance adjuster configured to adjust a luminance of at least one of the other camera images based on a luminance of the representative image;
a synthetic image generator configured to generate a synthetic image showing a periphery of the vehicle, based on the representative image and the other camera images the luminance of at least one of which has been adjusted by the first adjuster; and
an image provider configured to output, to a display device installed in the vehicle, information corresponding to the synthetic image.

Abstract
An image processing device configured to be installed in a vehicle includes an image acquirer, an image selector, a first luminance adjuster, a synthetic image generator, and an image provider. The image acquirer acquires camera images captured by cameras provided on the vehicle. The image selector selects one of the camera images as a representative image based on luminances of the camera images. The first luminance adjuster adjusts a luminance of at least one of the other camera images based on a luminance of the representative image. The synthetic image generator generates a synthetic image showing a periphery of the vehicle, based on the representative image and the other camera images the luminance of at least one of which has been adjusted by the first adjuster. The image provider outputs, to a display device installed in the vehicle, information corresponding to the synthetic image.

7. An image processing device configured to be installed in a vehicle, comprising:
-
an image acquirer configured to acquire a camera image captured by a camera provided on the vehicle; a first average calculator configured to divide the camera image into a plurality of regions each of which includes a plurality of pixels, and to calculate, for each of the regions, an average value of luminances of the respective pixels as a first average value; a region selector configured to select at least one of the regions in which the first average value is no greater than a threshold value; a luminance adjuster configured to adjust an entire luminance of the camera image based on the luminance of the at least one of the regions selected by the region selector; an image provider configured to output, to a display device installed in the vehicle, information corresponding to the camera image the entire luminance of which has been adjusted by the luminance adjuster; a second average calculator configured to calculate an average value of luminances of the pixels included in the at least one of the regions selected by the region selector, as a second average value; and a threshold updater configured to update the threshold value based on the second average value. - View Dependent Claims (8, 9, 10)
