Digital image capture device and brightness correction method thereof |
摘要 |
A digital image capture device and a brightness correction method thereof are described. The digital image capture device is adapted to correct the brightness value of a shot object in a digital image through the compensation of a strobe during shooting. The method includes setting a shooting magnification of the digital image capture device to the shot object; capturing a pre-shot image at least including the image of the shot object; triggering a strobe to emit a main flash onto the shot object, so as to shoot a digital image; setting a plurality of light measuring areas in the digital image; calculating a corresponding object distance of the shot object from each of the light measuring areas; establishing a shading table according to each of the object distances; and loading the shading table to adjust the brightness value of each of the light measuring areas in the digital image. |
