摘要： A projector is often positioned so that its optical axis is at an imperfect orthogonal angle with respect to a projection screen. This position causes a keystone distortion as well as imperfect focus in the projected image. To correct these undesirable problems, initially, a lens and/or an image-forming plate is independently repositioned to bring the projected image into focus based upon user input data. The keystone distortion is also corrected by redrawing the image on an image-forming surface based upon additional user input data.

摘要： A 3-D visual simulating system stores image data sets in a predetermined viewing space for right and left visual field and selects a portion of the stored image data corresponding to the current visual field for displaying it to an observer. The 3-D image stimulus changes according to the current visual field of the observer and the location of the observer in a predetermined visual space in a manner that undesirable perceptional effects are substantially eliminated. The image data sets are stored in a reduced space in an efficient manner for retrieval.

摘要： A composite image is generated from partially overlapping adjacent images taken at a single location along a plurality of axes. The angular relation among the overlapping images is initially determined based upon a common pattern in an overlapping portion of the images. The overlapping images are each converted to with respect to one of the images selected as a standard image based upon the previously determined angular relation.

摘要： The method and a system for determining coefficients correct distortion aberration based upon corresponding portions of partially overlapping images. These images are generally generated without any specific reference markers in the image for determining the distortion caused by an optical system.

摘要： An intensity value is independently estimated based upon interpolated values as well as measured sensor values according to the location of an individual sensor within a sensor unit. The interpolated values are in either CrCb or RGB values while an estimated intensity value is in Y value. The independent intensity value substantially improves color resolution.

摘要： An information processing apparatus includes a correlation unit that correlates distance information indicating a distance to an emission position of electromagnetic waves emitted in a shooting direction of a plurality of image pickup units with a first pixel in a first image that constitutes images taken by the image pickup units, the distance information being obtained based on reflected waves of the electromagnetic waves and the first pixel corresponding to the emission position of the electromagnetic waves, and a generation unit that generates a parallax image by using the distance information correlated with the first pixel for parallax computation of pixels in a second image that constitutes the images.
