Apparatus, method, and program for processing image |
摘要 |
An image-processing apparatus includes an average-luminance calculating unit that calculates the average luminance of pixels in an image, a correction-factor calculating unit that calculates a correction factor corresponding to the luminance of each pixel, a correction-value calculating unit that calculates a correction value corresponding to each pixel based on the average luminance and the correction factor, and an adding unit that adds the correction value to the luminance. The correction-value calculating unit sets the correction value to a maximum value of zero when the luminance has a maximum value.
