A solution to the problem of image and video stitching is disclosed that compensates for the effects of lens distortion, camera misalignment, and parallax in combining multiple images. The disclosed image stitching technique includes depth or disparity estimation, alignment, and blending processes configured to be computationally efficient and produce quality results by limiting the presence of noticeable seams and artifacts in the final stitched image. An inter-frame approach applies image stitching to video frames to maintain temporal continuity between successive frames across a stitched video output having a 360-degree viewing perspective. A temporal adjustment is configured to improve temporal continuity between a subsequent frame and a previous frame in a sequence of video frames.

Imaging device, image display device, and program with intruding object detection

An image processing device of the present invention includes a color-gamut determining part, a color-space determining part, and a color-space conversion part. The color-gamut determining part determines a color gamut as a range of color distribution from input image data. The color-space determining part determines a color space substantially covering the color gamut determined by the color-gamut determining part. The color-space conversion part converts the input image data into such image data that is rendered in the determined color space. The colors of the subject can thus be reproduced accurately from the converted image data.

Image processing device, electronic camera, and image processing program

The present invention includes a color converting section carrying out color conversion processing and a coefficient correcting section setting a correcting coefficient group to a coefficient group of the color conversion. The coefficient correcting section sets a local area containing a pixel to be processed, and calculates 'feature information of the local area' containing at least one of averaged color information, averaged luminance information, and flatness on the basis of the pixel signals of the local area. The coefficient correcting section determines a correcting coefficient group to be used for the pixel to be processed on the basis of the feature information of the local area. With this construction, the present invention suppresses influence of noise when changing the color conversion processing for each pixel.

Thus, it divides the image into plural small areas; generates image information indicating a characteristic of the image for each small area; determines an evaluation value indicating luminosity of each pixel constituting the image, according to the image information generated for each small area and image information generated for each of adjacent small areas to the each small area; and performs an image processing on each pixel of the image according to the determined evaluation value. A digital still camera of the invention can appropriately correct a gradation of an image created by shooting in accordance with the image. Moreover, an image-processing program and an image-processing method of the invention realize appropriate gradation correction in accordance with an image to be processed.

A digital still camera includes an image-capturing unit capturing a subject image via an image-capturing lens to create an image, a focus detecting unit detecting focus in accordance with the image created by the image-capturing unit, an image-capturing lens driving unit driving the image-capturing lens in accordance with a result of the focus detection provided by the focus detecting unit, and a receiving unit receiving an instruction to initiate image capture by the image-capturing unit. When the receiving unit receives the instruction to initiate image capture, the image-capturing unit captures the subject image successively to create a plurality of images, while the image-capturing lens driving unit drives the image-capturing lens successively. Accordingly, it is possible to provide an image in a high in-focus state while shortening the time required until an image is actually captured after an instruction is provided to initiate the capture of the image.

Image processing apparatus, image processing program, and image processing method

A color photographing device is equipped with a light-receiving section having a red pixel selectively receiving red light and outputting a red pixel signal and a green pixel selectively receiving green light and outputting a green pixel signal. The color photographing device is further equipped with an optical filter disposed on the side with a light-receiving surface of the light-receiving section. The optical filter substantially equalizes the signal level of the red pixel signal and the signal level of the green pixel signal when achromatic color illuminated by a solar light source in the daytime is photographed. Therefore, a white balance gain Wr at about 5000K can be lowered as compared with a conventional color photographing device. Accordingly, reduction of color noises and enhancement of gradation can be expected.
