摘要： A stereoscopic image aligning apparatus (200) automatically aligns image pairs for stereoscopic viewing in a shorter amount of time than conventional apparatuses, which is applicable to image pairs captured by a single sensor camera or a variable baseline camera, without relying on camera parameters. The stereoscopic image aligning apparatus (200) includes: an image pair obtaining unit (205) obtaining an image pair including a left-eye image and a right-eye image corresponding to the left-eye image; a corresponding point detecting unit (252) detecting a corresponding point representing a set of a first point included in a first image that is one of the images of the image pair and a second point included in a second image that is the other of the images of the image pair and corresponding to the first point; a first matrix computing unit (254) computing a homography transformation matrix for transforming the first point such that a vertical parallax between the first and second points is smallest and an epipolar constraint is satisfied; a transforming unit (260) transforming the first image using the homography transformation matrix; and an output unit (210) outputting: a third image that is the transformed first image; and the second image.

摘要： An image capturing device includes: a pre-capturing module which captures an imaging target at each of different focus positions in a predetermined focus range and outputs, as a capturing result, a plurality of pre-captured images lower in resolution than the output image; an object sharpness evaluating module which computes a sharpness level of each of the pre-captured images captured by the pre-capturing module; a focus varying range determining module which determines a focus position varying range within the predetermined focus range based on sharpness levels computed by the object sharpness evaluating module, such that a signal-to-noise ratio of the output image is greater than or equal to a predetermined threshold; and an image capturing module which captures the imaging target while varying the focus position according to the focus position varying range determined by the focus varying range determining module, and outputs the output image as a capturing result.

摘要： A distance estimation device (1x) prevents the variation in distance estimation accuracy that has been a problem in distance estimation performed using an all-in-focus image and an arbitrary-focal-depth image. The distance estimation device can estimate a focal distance of any subject with a high degree of accuracy, and includes: a first generation unit (10w) generating a first distance map indicating a focal depth determined from an all-in-focus image and a first focal-depth image; a second generation unit (11w) generating a second distance map indicating a focal depth determined from the all-in-focus image and a second focal-depth image; and a distance map synthesis unit (14) synthesizing the generated first distance map and the generated second distance map to generate a synthetic distance map.
