  • Publication number: 20090102956
    Abstract: Method and apparatus for a fast (low F/number) computational camera that incorporates two arrays of lenses. The arrays include a lenslet array in front of a photosensor and an objective lens array of two or more lenses. Each lens in the objective lens array captures light from a subject. Each lenslet in the lenslet array captures light from each objective lens and separates the captured light to project microimages corresponding to the objective lenses on a region of the photosensor under the lenslet. Thus, a plurality of microimages are projected onto and captured by the photosensor. The captured microimages may be processed in accordance with the geometry of the objective lenses to align the microimages to generate a final image. One or more other algorithms may be applied to the image data in accordance with radiance information captured by the camera, such as automatic refocusing of an out-of-focus image.

  • Patent number: 7515189
    Abstract: Described is a method of image dissection that utilizes random, non-rectangular scan patterns and irregular size and shape picture elements. To do this, matched faceplates would be cut from a fused scrambled fiber optic bundle with fibers of random diameters and cross sections. One faceplate would be placed in contact with the imager focal plane surface. The other faceplate would be placed in contact with the light-emitting surface of the display device. Thus, the images input and output from the imaging system of the invention would match. A video link would connect the focal plane imager and the raster scan display. The raster scan would be accomplished in a random manner so as to provide the best quality refresh rate and image.

  • Patent number: 7515317
    Abstract: A method of compensating a zipper image by a K-value, and a method of calculating the K-value. Whether the nth primitive pixel of the mth line is obtained by primary line scan is determined. If the nth primitive pixel of the mth line is obtained by primary line scan, the nth primitive pixel of the mth line is compensated as the nth primitive pixel of the mth line minus a sum of the (n?1)th primitive pixel of the (m?k)th line and the (n+1 )th primitive pixel of the (m?k)th line multiplied by the K-value. If the nth primitive pixel of the mth line is obtained by secondary line scan, the nth primitive pixel of the mth line is compensated as the nth primitive pixel of the mth line minus a multiplication of the K-value and a sum of the (n?1)th primitive pixel of the (m+k)th line and the (n+1)th primitive pixel of the (m+k)th line.

  • Patent number: 7492412
    Abstract: A solid-state image pickup apparatus includes a low-sensitivity decision section made up of an arithmetic circuit and a data decision circuit. During RAW mode recording operation, the arithmetic circuit executes sensitivity correction on low-sensitivity pixel data. The data decision circuit compares the low-sensitivity pixel data thus corrected with high-sensitivity pixel data to thereby produce map data pixel by pixel. Subsequently, pixel data are omitted on the basis of an embedding condition assigned to basic data set beforehand and the map data, whereby recording data a regenerated. The recording data are then recorded in a recording medium together with the map data and high-sensitivity pixel data.

  • Patent number: 7432962
    Abstract: A method of broadening a dynamic range is applied to a solid-state image sensor of the type including photodiodes each being divided into a main and a subregion different in photosensitivity from each other. While the quantity of light to be incident on a photodiode is reduced, a signal charge is read out only from the main region of the photodiode. The signal charge is digitized and then written to two image memories. Digital signals thus stored in the image memories are respectively amplified by white balance gain circuits with different gains. The resulting digital signals are combined by an image synthesizer. The method can therefore broaden the dynamic range of the image sensor by using only the main regions of the photodiodes.

  • Patent number: 7420607
    Abstract: A solid-state imaging element contains a plurality of photoelectric converting regions, vertical transfer portions, a horizontal transfer portion, and an output portion. These photoelectric converting regions are arranged on a surface of a semiconductor substrate along a row direction, and a column direction perpendicular to the row direction. The photoelectric converting regions are subdivided into main regions “m” having relatively wide light-receiving areas, and sub-regions “s” having relatively narrow light-receiving areas. These main areas “m” and sub-areas “s” produce signal electron charges corresponding to light having predetermined spectral sensitivities, and then store the produced signal electron charges. A partial photoelectric converting region within the photoelectric converting regions corresponds to different color light with respect to the main region “m” and the subregion “s.
