| 20080219585 | Image Processing Apparatus, Image Apparatus, Image Processing Method, and Computer Program - An image processing apparatus includes the following elements. An image input unit receives a long-time exposure image and a short-time exposure image. An image analysis unit detects a brightness-change pixel in which a brightness change has occurred during a photographic period on the basis of analysis of pixel values in the long-time exposure image and the short-time exposure image. A pixel value correction unit corrects a pixel value of the detected brightness-change pixel. In the pixel value correction unit, a combined image generator selectively combines pixel values in the long-time exposure image and pixel values in the short-time exposure image to generate a combined image; an intermediate image generator generates a blurred image of the combined image; and an output image generator determines a pixel value of the detected brightness-change pixel using a pixel value of a corresponding pixel in each of the combined image and the blurred image. | 09-11-2008 |
