Abstract: This invention solves the problem that objects in the field of view of reading glasses using multifocal lenses for correcting ocular refractive errors such as presbyopia appear distorted. This image display device is provided with the following: a distance computation unit that computes the distance to a subject in a field-of-view image; a visual-acuity-information acquisition unit that stores visual-acuity information for the user in advance; a corrected-image generation unit that generates and outputs a corrected image on the basis of the field-of-view image and an eye image generated from the field-of-view image, the distance information, and the visual-acuity information; and a display unit that displays the corrected image by superimposing same onto the user's field of view. Since the corrected image is superimposed without the use of lenses, lenses being the cause of the abovementioned distortion, the user can see close objects clearly.

Abstract: A crossing point detector includes memory and a crossing point detection unit that reads out a square image from a captured image in the memory, and detects a crossing point of two boundary lines in a checker pattern depicted in the square image. The crossing point detection unit decides multiple parameters of a function model treating two-dimensional image coordinates as variables, the parameters optimizing an evaluation value based on a difference between corresponding pixel values represented by the function model and the square image, respectively, and computes the position of a crossing point of two straight lines expressed by the decided multiple parameters to thereby detect the crossing point with subpixel precision. The function model uses a curved surface that is at least first-order differentiable to express pixel values at respective positions in a two-dimensional coordinate system at the boundary between black and white regions.

Abstract: There is provided an image capturing apparatus that captures a plurality of images, calculates a three-dimensional position from the plurality of images, and outputs the plurality of images and information about the three-dimensional position. The image capturing apparatus includes an image capturing unit, a camera parameter storage unit, a position calculation unit, a position selection unit, and an image complementing unit. The image capturing unit outputs the plurality of images using at least three cameras. The camera parameter storage unit stores in advance camera parameters including occlusion information. The position calculation unit calculates three dimensional positions of a plurality of points. The position selection unit selects a piece of position information relating to a subject area that does not have an occlusion, and outputs selected position information. The image complementing unit generates a complementary image, and outputs the complementary image and the selected position information.
