A clipping processing portion is provided with: a subject detection portion that detects a main subject and a sub-subject from an input image; a degree-of-relationship calculation portion that calculates the degree of relationship between the main subject and the sub-subject; a clip region setting portion that sets a clip region based on the positions of the main subject and the sub-subject in the input image and the degree of relationship; a clipping portion that clips the clip region from the input image. The clip region setting portion sets the clip region so as to include the main subject and the sub-subject having the high degree of relationship thereof.

Image processing device, image processing method and electronic apparatus

An image-taking apparatus generates an output image from a photographed image obtained by photographing and displays this output image on a display screen of a display section. The image-taking apparatus includes a recognition processing section for recognizing a specific subject (facial region of a person, or a facial component such as eyes) included in the photographed image. Referring to results of this recognition, the image-taking apparatus evaluates the dimension of the specific subject in each photographed image. If the dimension evaluated is relatively large, a relatively small magnification ratio to be employed upon the generation of the output image from the photographed image is provided. If the dimension evaluated is relatively small, a relatively large magnification ratio to be employed upon the generation of the output image from the photographed image is provided. As a result, the dimension of the specific subject in the output image is kept substantially constant.

Image-taking apparatus and output image generation method

An image processing device generates a high-resolution image from a plurality of low-resolution images, in which the high-resolution image has a resolution higher than a resolution of the low-resolution images. The image processing device includes a reference image setting portion for selecting a reference image from the plurality of low-resolution images based on image information of the plurality of low-resolution images. The image processing device generates the high-resolution image by performing a resolution increasing process on the plurality of low-resolution images for increasing a resolution with respect to the reference image.

Image processing device and method, and image sensing apparatus

A super-resolution processing portion has a high-resolution image generation portion that fuses a plurality of first input images together to generate a high-resolution image. The first input images are shot at a shutter speed equal to or faster than the super-resolution limit shutter speed, which is the lower-limit shutter speed that enables super-resolution processing to make the resolution of the output image equal to or higher than that of the input images. According to the amount of exposure, one of the following different methods for super-resolution processing is selected: a first method that yields as the output image the high-resolution image; a second method that yields as the output image a weighted added image resulting from weighted addition of the high-resolution image and an image based on an averaged image; and a third method that yields as the output image a weighted added image resulting from weighted addition of the high-resolution image and an image based on a second input image.

Image-shooting apparatus capable of performing super-resolution processing

A representative-value calculator calculates a representative value of signal values of pixels included in each of divided regions of a neighboring region of a pixel of interest. The divided regions are obtained by dividing the neighboring region into the predetermined number of divisions. The number of divisions is determined based on a frequency band in an input image signal. A difference-absolute-value calculator calculates a difference absolute value between a signal value of the pixel of interest and each of the representative values of the respective divided regions. A weight calculator calculates a weight for each of the representative values of the respective divided regions according to the difference absolute value. A normalization processor normalizes the sum of products of the representative values of the respective divided regions and the weights for the representative values of the respective divided region.

Noise reduction circuit and image processing device

Based on, for example, the image at the start of a movie, a thumbnail image is tentatively generated and is stored in a header file. If a predetermined triggering condition is fulfilled during movie shooting, a thumbnail image is generated from the frame image at the timing that the triggering condition is fulfilled, and the thumbnail image existing in the header file is replaced with the newly generated thumbnail image. The triggering condition is fulfilled, for example, if, after zooming-in, the angle of view has been kept fixed for a predetermined period or longer, or if the focus has been kept locked for a predetermined period.
