The present invention particularly relates to an image processing apparatus in which motion blur contained in a blurred image can be eliminated. An area specifying unit 103 specifies a non-mixed area formed of a foreground area consisting of foreground object components which form a foreground object and a background area consisting of background object components which form a background object, or a mixed area in which the foreground object components and the background object components are mixed. A separating/blur-eliminating unit 1503 simultaneously performs processing for separating the foreground object components and the background object components from the pixel data of the mixed area and processing for eliminating motion blur from the separated foreground object components based on a result obtained by specifying the area. The present invention is applicable to an image processing apparatus in which a difference between a signal detected by an image-capturing device and the real world is considered.

The invention discloses an image anti-shake method, electronic equipment and a storage medium. The electronic equipment has an optical anti-shake mode and an electronic anti-shake mode, and the methodcomprises the steps: employing the optical anti-shake mode to control a shooting module for shooting, and obtaining the measurement offset of the center of a lens of the shooting module and the current working temperature of the shooting module through measurement; correcting the measurement offset based on a preset offset correction strategy and the current working temperature to obtain a real offset of the center of the lens; and performing electronic anti-shake processing on the shot image by adopting an electronic anti-shake mode based on the real offset of the center of the lens.

A motion-setting section (61) sets a motion amount and a motion direction for obtaining processing coefficients. A student-image-generating section (62) generates student images obtained by adding a motion blur to a teacher image not only based on the set motion amount and the set motion direction but also by changing at least one of the motion amount and motion direction in a specific ratio and student images obtained by adding no motion blur to the teacher image. A prediction-tap-extracting section (64) extracts, in order to extract a main term that mainly contains component of the target pixel, at least a pixel value of pixel in the student image whose space position roughly agrees with space position of the target pixel in the teacher image. A processing-coefficient-generating section (65) generates processing coefficients for predicting the target pixels in the teacher images from the pixel values of extracted pixels based on a relationship between the pixels thus extracted and the target pixels in the teacher images. The processing coefficients that are suitable for any motion blur removing which is robust against any shift of the motion vector can be generated through learning.
