Abstract: A technique for performing high-quality cluster type FM halftone image output without “anisotropy” or “sweep out texture” phenomenon is provided. An error diffused to a current pixel position and a random number RND are added by an adder to multi-level pixel data as a subject of binarization, and supplied as pixel data Pxy to a selector. The selector compares the pixel data Pxy with thresholds, and supplies the pixel data Pxy to one of a highlight portion processor, a dark portion processor and an intermediate portion processor. The highlight and dark portion processors refer to already-binarized results within a range determined in accordance with the value of the input pixel data Pxy, and determine a binarization result Qxy. The intermediate portion processor compares a threshold, which monotonously increases in accordance with the value of the pixel data Pxy, with the pixel data Pxy, thereby determines the binarization result Qxy.

Abstract: A key region extraction unit (303) extracts a first region including pixels having a predetermined pixel value in a physical space image. A motion vector detection unit (304) calculates motion vectors at a plurality of portions on the physical space image. An object region detection unit (305) specifies, using the motion vectors, a second region to be merged with the first region. When superimposing a virtual space image on the physical space image, an image composition unit (308) excludes a composition region obtained by merging the first region with the second region from a virtual space image superimposition target.

Abstract: An image capturing apparatus performs autofocus control that uses a face detection function. The image capturing apparatus sets a face region as an AF frame if face detection is successful. However, if a state in which face detection is successful transitions to a state in which face detection has failed, and furthermore a variation between subject distances is less than or equal to a threshold value, the image capturing apparatus maintains the previous AF frame setting instead of changing the AF frame setting. If the variation in subject distances is greater than the threshold value, the image capturing apparatus sets the AF frame to a predetermined region that does not follow a face region.
