When a plurality of images are to be overlapped and synthesized, coincidence degrees between the plurality of images in an area near the boundary of a common area are calculated, and the plurality of images are overlapped and synthesized so that an area near the boundary having a high coincidence degree appears on the overlapped image. Thereby, it is possible to avoid the duplexing of the subject in the common area and unnatural ruptures on the boundary made by the overlapping while reducing the number of processes for the synthesizing.

An image processing apparatus creates a basic-structure component image representing an image that an input image except edge is smoothed while preserving the edge in the input image; and creates a detail component image representing an image that the basic-structure component image is subtracted from the input image. Subsequently, the image processing apparatus decomposes the detail component image into a plurality of frequency-band images through multiresolution transform processing, and performs noise removal on the obtained frequency-band images. After that, the image processing apparatus performs inverse multiresolution transform processing of combining the noise-removed frequency-band images, thereby creating a noise-removed detail-component image.

An image processing apparatus includes a face detection processing unit that reduces an image of a frame to be processed to a first level among several reduction levels to generate a reduced image of the frame to be processed, with one of frames included in a moving image as the frame to be processed, and compares the reduced image generated by the reducing unit and the learning data to extract a face image from the reduced image. When the extraction of the face image from the frame to be processed is ended, the face detection processing unit updates the frame to be processed to a next frame subsequent to the frame to be processed and generates a reduced image that is reduced to another level other than reduction levels adjoining the first level.

To perform image correction according to the features of an input image and output a fine and conspicuous image corresponding to a variety of scenes; an image correcting apparatus detects, from the pixels of the input image, the dark pixels that have the respective pixel values equal to or smaller than a first threshold value. Then, for each dark pixel having the pixel value equal to or smaller than the first threshold value, the image correcting apparatus detects calculates the shading variation between the dark pixel and the corresponding surrounding pixels, calculates a correction amount based on the calculated shading variation, and performs image correction with the calculated correction amount.
