Disclosed is an apparatus for forming a composite image of a scene from a plurality of overlapping elemental images, the apparatus comprising:a selector for selecting one point in one of the plurality of images and another point in a second one of the plurality of images, the first point and the other point being overlaid in the composite image and being of substantially the same point in the scene;a determiner for determining, when the first point and the other point are overlaid, the gradient across the overlap between the first and other elementary image; andan adjuster for adjusting one of the first and second elementary image to minimise the gradient across the overlap. A corresponding method is also disclosed.

A two-dimensional image can be displayed in a desired position, a desired aspect ratio of the display image can be maintained, and such an elemental image array as to maximize an interpolating effect can be produced. A producing method of an elemental image array for three-dimensional image display includes: converting the resolution of the two-dimensional image into substantially the same resolution of a three-dimensional image display device; obtaining multipoint images by shifting the position to sample the two-dimensional image after the resolution conversion at regular intervals in the horizontal direction; and rearranging the multipoint images according to the positional relationship between exit pupils and projecting directions.

A stereoscopic display apparatus includes a liquid-crystal display device that has display pixels arranged in a matrix and displays an elemental image array formed from a plurality of field images on the display pixels to render stereoscopic display, a parallax creating unit provided on the front surface or the rear surface of the liquid-crystal display device, and a directional backlight that emits light through the liquid-crystal display device then through the parallax creating unit and switches directions of the thus-emitted light among a plurality of directions according to a display of the field image is disclosed.

It is possible to provide a three-dimensional image display device which can improved a final resolution balance and can prevent display blocking. A three-dimensional image display device includes: a two-dimensional image display device where pixels constituting a pixel group displaying an elemental image are arranged in a matrix shape; and an optical plate which has exit pupils corresponding to the pixel group and controls light rays from the pixels of the pixel group, wherein the exit pupils in the optical plate are constituted so as to be continued in an approximately vertical direction, and an angle formed between a direction in which the exist pupils are continued and a column direction of a pixel arrangement in the two-dimensional image display device is given by arctan (1 / n) when n is a natural number which is different from multiples of 3.

This invention provides a stereoscopic image display apparatus and a stereoscopic image display method capable of preventing a luminance difference from being caused between left and right eyes irrespective of the observation position even if the viewing zone is wide and the number of parallaxes is large. The stereoscopic image display apparatus includes: a display unit (10) including pixels arranged in a matrix form in a longitudinal direction and a lateral direction; an optical plate (20) installed so as to be opposed to the display unit and having linear optical openings prolonged in a longitudinal direction and arranged in a lateral direction; and a luminance compensation processing unit which, for each of elemental images associated with the optical openings, sets a brightness of an image displayed on a pixel located in a center of the elemental image smaller than a brightness of an image displayed on a pixel located in each of boundaries of the elemental image.

Measurements made by a pulsed neutron tool with two or more gamma ray detectors are used to provide a mineralogical and / or elemental image of the formation. This may be used in reservoir navigation and in furthering the understanding of the geology of the prospect. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).

In a three-dimensional image display apparatus in which a lenticular plate and shutter device are arranged in front of a display module, one frame image is displayed using n field images. To display each field image, a shutter device is driven to substantially simultaneously open a group of shutter elements for every n lenses along a horizontal direction. Thus, light beams are transmitted from lenses through the shutter elements to an observing zone. The group of the opened shutter elements is sequentially changed in response to n switchings of the field. The switching of shutter elements is synchronized with the pixels on the display surface sequentially rewritten from top to bottom by linear sequential driving during the switching of the field. The elemental image is projected on the viewing zone via the lenses and the shutter elements.
