  • Patent number: 8400521
    Abstract: An electronic camera includes an imager, having an imaging surface capturing a scene, which repeatedly outputs a scene image. An extractor extracts a specific reference image coincident with a partial image outputted from the imager corresponding to a predetermined area allocated to the imaging surface, from among a plurality of reference images. An adjuster executes a process of adjusting an exposure amount by emphasizing the predetermined area in parallel with the extraction process. An identifier identifies a color of an object equivalent to the partial image, corresponding to extracting the specific reference image. A corrector executes a process of correcting a tonality of the scene image with reference to the identified result, in place of the extraction process. A searcher searches for a partial image coincident with the specific reference image from the scene image having the corrected tonality.

  • Patent number: 8363118
    Abstract: An image processing device calculates a coordinate transformation coefficient for each of a plurality of regions, and, for at least one point of interest in a local region, calculates a correction amount that is used when blur in a target image is corrected using a coordinate transformation coefficient for the local region and a correction amount that is used when the blur in the target image is corrected using a coordinate transformation coefficient for a region neighboring the local region. In this case, if the correction amount difference does not fall within a predetermined limit value, a coordinate transformation coefficient is newly obtained for each of the plurality of regions including the local region so that the correction amount difference falls within the predetermined limit value, and the target image is corrected for each region using the newly obtained coordinate transformation coefficient.

  • Patent number: 8345144
    Abstract: Methods and apparatus for rich image capture using focused plenoptic camera technology. A radiance camera employs focused plenoptic camera technology and includes sets of modulating elements that may be used to modulate the sampling of different aspects of the range of plenoptic data. The radiance camera, via the modulating elements, may capture a particular property of light, such as luminance, color, polarization, etc., differently in different microimages or in different portions of microimages. With the focused plenoptic camera technology, the microimages are captured at the same time in a single image. Thus, multiple microimages of the same image of a scene may be captured at different exposures, different colors, different polarities, and so on, in a single image at the same time. Captured images may be used, for example, in High Dynamic Range (HDR) imaging, spectral imaging, polarization imaging, 3D imaging, and other imaging applications.

  • Patent number: 8345149
    Abstract: The optical path of the light having spread at each point of an object to be shot is limited by an iris unit of a density filter. Since the density filter unit has a desired transmittance characteristic, the amount of the light passing through the density filter unit continuously changes from the center of the luminous flux toward the periphery. After the luminous flux forms an image on the image forming surface, it spreads toward the light-receptive surface of an image sensor, and becomes an image spreading on the light-receptive surface in a predetermined range.
