| 20090213251 | IMAGING APPARATUS AND IMAGING DEVICE - An imaging device having five color filters. The five color filters include three color filters of a R (red) filter, a G (green) filter, and a B (blue) filter of a primary color system and two color filters of a Y (yellow) filter and a C (cyan) filter of a complementary system. The G filter has a checker shape G filter so that the space information of green is obtained four times larger than that of each of the other colors. | 08-27-2009 |
| 20110149126 | MULTIBAND IMAGE PICKUP METHOD AND DEVICE - The invention provides a multiband image pickup method and device with good color reproducibility, which is capable of imaging a subject with a number of imaging bands of not less than 4 colors and obtain a color image of not less than 3 colors without lowering spatial resolution. A first imaging of a subject image is performed by a single-plate imaging device having a color filter composed of 5 colors of R, O, G, C and B. A control unit shifts the imaging element by a shift drive unit so that each light having formed an image on the each filter of R, B and G of the color filters forms an image on a position of the each filter of O, C and G of the color filters and, thereafter a second imaging is performed. A image processing unit generates 2 3-band Bayer images based on captured images obtained by the first imaging and the second imaging, and generates a multiband image of not less than 3 colors from them. | 06-23-2011 |

| 20120038801 | IMAGING ELEMENT, DRIVE DEVICE FOR AN IMAGING ELEMENT, DRIVE METHOD FOR AN IMAGING ELEMENT, IMAGE PROCESSING DEVICE, PROGRAM, AND IMAGING DEVICE - An imaging element includes: a plurality of color filters arranged in a Bayer array; photoelectric conversion elements provided for the respective color filters; a signal adder circuit which carries out additions in each of the unit grids, by (i) adding up signals outputted from two photoelectric conversion elements corresponding to different colors of two color filters out of four color filters, and (ii) adding up signals outputted from two photoelectric conversion elements corresponding to remaining two color filters; and an A/D converter. The imaging element outputs: (i) a first digital image signal where signals of one color out of Ye (yellow) and Cy (cyan), and signals of G, are alternately placed; and (ii) a second digital image signal where signals of an other color out of Ye and Cy, which is different from the one color, and signals of Mg (magenta), are alternately placed. | 02-16-2012 |
| 20120092535 | COLOR FILTER, IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, IMAGE-CAPTURE APPARATUS, IMAGE-CAPTURE METHOD, PROGRAM AND RECORDING MEDIUM - A color filter allows a light signal to pass through by each pixel and be incident on an imaging device. The light signal is inputted through a lens and including one of plural different spectral components. The plural different spectral components include a first spectral component which has a widest frequency bandwidth among the plural different spectral components, a second spectral component corresponding to a predetermined frequency band close to a frequency that causes no chromatic aberration of the lens, and a third spectral component expressed in terms of a linear sum of a value resulting from multiplying the first spectral component by a first weighting factor and a value resulting from multiplying the second spectral component by a second weighting factor. | 04-19-2012 |
| 20130293750 | IMAGE SENSING APPARATUS, METHOD OF CONTROLLING OPERATION OF SAME AND IMAGE SENSING SYSTEM - When a central pixel having a red component is generated by interpolation, mixing is performed using red-component pixels lying along the diagonal directions thereof. When a central pixel having a green component is generated by interpolation, mixing is performed using green-component pixels located above, below and to the left and right thereof. When a central pixel having a blue component is generated by interpolation, no mixing processing is executed. A reduction in image size is performed at the same time as pixel interpolation. | 11-07-2013 |
| 20140118586 | IMAGING APPARATUS - An imaging apparatus has a color filter array, an image sensor, and a differential information acquisition unit. In the color filter array, including five or more types of color filters are arranged in a two dimensional form. The image sensor has a plurality of pixels covered by the color filters, and the plurality of pixels generate pixel signals. The acquisition unit designates one of the pixels covered by the color filters of interest as a pixel of interest one pixel at a time in order. The acquisition unit calculates first differential information based on pixel signals generated by two of the pixels arranged on both sides of the pixel of interest along the first direction. The acquisition unit calculates second differential information based on pixel signals generated by two of the pixels arranged on both sides of the pixel of interest along the second direction. | 05-01-2014 |
| 20140267849 | SPECTRAL CAMERA WITH INTEGRATED FILTERS AND MULTIPLE ADJACENT IMAGE COPIES PROJECTED ONTO SENSOR ARRAY - A spectral camera for producing a spectral output is disclosed. The spectral camera has an objective lens for producing an image, an optical duplicator, an array of filters, and a sensor array arranged to detect the filtered image copies simultaneously on different parts of the sensor array. Further, a field stop defines an outline of the image copies projected on the sensor array. The filters are integrated on the sensor array, which has a planar structure without perpendicular physical barriers for preventing cross talk between each of the adjacent optical channels. The field stop enables adjacent image copies to fit together without gaps for such barriers. The integrated filters mean there is no parasitic cavity causing crosstalk between the adjacent image copies. This means there is no longer a need for barriers between adjacent projected image copies, and thus sensor area can be better utilized. | 09-18-2014 |
| 20150334357 | WAFER LEVEL CAMERA HAVING MOVABLE COLOR FILTER GROUPING - An image capture unit includes an image sensor and a lens structure disposed proximate to the image sensor to focus an image onto the image sensor. A movable color filter grouping is disposed over the lens structure. The movable color filter grouping includes a plurality of N color filters arranged therein such that all light that is incident upon the image sensor through the lens structure is directed through only one of the plurality of N color filters of the movable color filter grouping per each exposure of the image sensor. A positioning device is attached to the movable color filter grouping to reposition the movable color filter grouping such that substantially all of the light that is incident upon the image sensor through the lens structure is directed through a different one of the plurality of N color filters for each successive exposure of the image sensor. | 11-19-2015 |
