Photographing apparatus and method for compensating brightness of an image
First Claim
Patent Images
1. A photographing apparatus comprising:
- an image sensor for capturing a first image and a second image sequentially, said first image including a reference image part;
a calculation module for calculating average brightness degree of said reference image part as a reference brightness value, wherein a brightness difference between said reference brightness value and average brightness degree of an adjacent part of said first image succeeding said reference image part is greater than a threshold value, brightness of said first image and said reference brightness value cooperatively defining a first compensation ratio; and
a compensation module for compensating brightness of said second image according to said first compensation ratio.

Abstract
A photographing apparatus includes an image sensor for capturing first and second images sequentially, the first image including a reference image part; a calculation module for calculating average brightness degree of the reference image part for serving as a reference brightness value, wherein a brightness difference between the reference image part and an adjacent part succeeding the reference image part is greater than a threshold, brightness of the first image and the reference brightness value cooperatively defining a compensation ratio; and a compensation module for compensating brightness of the second image according to the compensation ratio.

14. A method for compensating brightness of an image in a photographing apparatus, comprising the steps of:
-
(1) capturing a first image, said first image including a reference image part;
(2) calculating average brightness degree of said reference image part for serving as a reference brightness value, wherein a brightness difference between said reference image part and an adjacent part succeeding said reference image part is greater than a threshold, brightness of said first image and said reference brightness value cooperatively defining a first compensation ratio;
(3) capturing a second image; and
(4) compensating brightness of said second image according to said first compensation ratio. - View Dependent Claims (15, 16, 17, 18, 19, 20)
