摘要： Disclosed is an image processing apparatus and a control method thereof that can correct the brightness of a pixel in an image. Reflection characteristics of environment light when the image is captured are estimated by applying smoothing to the image. The brightness of the pixel is corrected by computing a correction value for correcting the brightness of the pixel based on the reflection characteristics of the environment light and adding the correction value to the pixel. The brightness can be corrected while suppressing an amplification of noise and a loss of details of a subject.

摘要： An imaging device and its image processing for creating an image with less blur from a small number of images under different exposure conditions in a shortened processing time. The imaging device 10 captures an image by means of an optical system 11 and an imaging element 12 in a short exposure time with a high resolution and much noise and images in a long exposure time with low resolution and less noise. After signal processing by signal processing section 13, a CPU 14 detects the position variation between captured images and blurs, separates the edges blur and the noise by using the threshold from the two difference images, combines the two images at a varied combination ratio, and thereby creates an image with no blur and reduced noise.
