  • Patent number: 8786738
    Abstract: At least one green filter G having a filter characteristic for transmitting a green light component is formed in all of horizontal, vertical and diagonal directions in a block consisting of six optoelectronic transducers in each of the horizontal and vertical directions. Further, at least one blue filter B and red filter R having filter characteristics for transmitting a blue light component and a red light component are formed in the horizontal and vertical directions. Even an image obtained after ½ subsampling along each of the horizontal and vertical directions will contain pixels having a green component in all of the horizontal, vertical and diagonal directions in blocks of 6×6 pixels. The precision of reproducibility in interpolation processing is thus improved.

  • Patent number: 8780239
    Abstract: In an aspect of the present invention, only by storing the first correction coefficients corresponding to the colors of the color filters of the image pickup element and the second correction coefficients corresponding to the relative positions of the pixels to the position of the specific circuit element of the image pickup element, in the storage device, an adequate combination of the first correction coefficients and the second correction coefficients is selected for each pixel, and a calculation with it is performed with respect to the signal value of each of the pixels. Therefore, with an essential minimum number of correction coefficients, it is possible to quickly and accurately correct the variation in signal values caused by the color array for the color filters of the image pickup element and the variation in signal values caused by the structure in which multiple pixels share the specific circuit element.

  • Patent number: 8780237
    Abstract: A solid-state imaging apparatus 10 includes a solid-state imaging device 40, and a color filter 16 constituted of a first color filter 16a (first filter) and a second color filter 16b (second filter). The solid-state imaging device 40 photoelectrically converts light incident to a face S1 (first face) thereof to thereby capture an image of an object to be imaged. Arranged on the face S1 of the solid-state imaging device 40 is the first color filter 16a and second color filter 16b. The first color filter 16a is a filter that allows first wavelength band light to be selectively transmitted therethrough; the second color filter 16b is a filter that allows second wavelength band light in the longer wavelength side relative to the first wavelength band to be selectively transmitted therethrough.

  • Publication number: 20140184862
    Abstract: A digital color imager providing an extended luminance range, an improved color implementation and enabling a method for an easy transformation into another color space having luminance as a component has been achieved. Key of the invention is the addition of white pixels to red, green and blue pixels. These white pixels have either an extended dynamic rang as described by (U.S. Pat. No. 6,441,852 to Levine et al.) or have a larger size than the red, green, or blue pixels used. The output of said white pixels can be directly used for the luminance values Y of the destination color space. Therefore only the color values and have to be calculated from the RGB values, leading to an easier and faster calculation. As an example chosen by the inventor the conversion to YCbCr color space has been shown in detail.

  • Patent number: 8749673
    Abstract: The image generation device generates a new moving picture of a subject based on first and second moving pictures shot with a single-chip color image sensor, which detects two light rays including first and second color components, respectively, to represent the first and second color components of the subject. As the first moving picture has been shot in a longer exposure time than the second moving picture, the first picture has a lower frame rate than the second picture. The image generation device includes: a getting section which gets video signals representing the first and second moving pictures, respectively; a processing section which generates a new moving picture with as high a frame rate as the second moving picture based on the respective video signals representing the first and second moving pictures gotten; and an output section which outputs the new moving picture.

  • Patent number: 8749656
    Abstract: Previously available analog domain decimation techniques are limited to simple equally-weighted averaging of photosite outputs. Decimation of a Bayer pattern image by an even-factor, such as by two or six, using simple equally-weighted averaging of photosite outputs in the analog domain results in effective sampling locations that are unevenly spaced apart. Standard interpolation of the unevenly spaced effective sampling locations generates image artifacts that reduce the quality of the reconstructed image in the smaller format because standard interpolation methods assume that the effective sampling locations are evenly spaced. Implementations of systems, methods and apparatus disclosed herein aim to produce substantially evenly spaced effective sampling locations in the analog domain.
