  • Patent number: 7688363
    Abstract: An albedo estimating section produces an albedo image of an object from an original image captured by an image-capturing section by using light source information estimated by a light source information estimating section and shape information of the object obtained by a shape information obtaining section. An albedo super-resolution section performs super-resolution of the albedo image according to a conversion rule obtained from an albedo DB. A super-resolution section produces a high-resolution image obtained by performing super-resolution of the original image by using the super-resolution albedo image, the light source information and the shape information.

  • Publication number: 20100046906
    Abstract: A recording process records low-resolution video data while obtaining a high-resolution image in a window region being a portion of an entire image. Then, the process learns, as a resolution conversion rule, a resolution increasing parameter by using the high-resolution image. In a resolution increasing process, the resolution of the recorded low-resolution video data is increased by using the resolution increasing parameter learned in the recording process.

  • Publication number: 20100027879
    Abstract: The process captures a plurality of images under a light source whose luminance varies over time, such as a fluorescent lamp, under such an imaging condition that a plurality of images that are different from one another in terms of light source conditions can be captured (S11). The process detects a temporal luminance variation from the plurality of captured images (S12), estimates a shadow area by using the temporal luminance variation (S13), and performs an image process such as a process of synthesizing a linearized image or an image segmentation based on optical characteristics (S14).

  • Publication number: 20100013948
    Abstract: A multi-color image processor according to the present invention includes an image capturing section 101 and a signal processing section 104. The image capturing section 101 includes a color separating section 10 for separating visible radiation into at least two light rays with first- and second-color components, respectively, and first and second imagers 12 and 14 that receive the light rays with the first- and second-color components. The image capturing section 101 gets images with the first- and second-color components by making the first imager 12 decimate pixels to read, but making the second imager 14 read every pixel, on a field-by-field basis on respective arrangements of pixels of the first and second imagers 12 and 14.

  • Publication number: 20090304299
    Abstract: The resolution of an image of an object is increased. The illumination equation parameters of the object are estimated, and a resolution-increasing process is performed on the estimated illumination equation parameters. Then, the resolution-increased illumination equation parameters are synthesized together to produce a high-resolution image. If there is a pixel for which the estimation precision of the estimated illumination equation parameters does not satisfy a predetermined precision, the illumination equation parameters are estimated again while feeding back the resolution-increased illumination equation parameters.

  • Patent number: 7626585
    Abstract: A polarized image acquisition section shoots a subject through a polarizing element operable to set principal axes of which directions are different from each other. An incident plane specifying section specifies an incident plane of each pixel, and an incident angle computation section computes an incident angle of each pixel. A classifying section clusters pixels similar to each other in both incident plane and incident angle. A reflection component separation section performs reflection component separation on each clustered pixel set on the assumption of probabilistic independence between the diffuse reflection component and the specular reflection component.

  • Patent number: 7623174
    Abstract: For a first region being a portion of a storage section (202), a read-out pulse produced by a progressive scanning shift register (206) is used to perform a progressive read-out operation of reading out signals from all rows of image-storing pixels (221). For a second region including an entire region other than the first region, a read-out pulse produced by a skip scanning shift register (205) is used to perform a skip read-out operation of reading out signals from intermittently-selected rows of image-storing pixels (221). The progressive scanning shift register (206) produces the read-out pulse so that the first region moves every frame and an entire region of the storage section (202) is scanned over a plurality of frames.
