  • Patent number: 9503699
    Abstract: The present technique relates to an imaging device and an imaging method, an electronic device, and a program, which are configured to improve an SN ratio by combining addition reading and thin-out reading by signal processing similar to signal processing using thin-out reading. First, as illustrated in the left side of the drawing, G pixel and B pixel, which are sub-colors, of the top row of regions Z1, Z2 are subjected to thin-out reading. Next, for W pixels of the main color arranged in a checkerboard pattern in the regions Z1, Z2, two pixels tied by a straight line in the drawing are subjected to addition reading at the same tone timing. For W pixels of the main color arranged in a checkerboard pattern in regions Z3, Z4, two pixels tied by a straight line in the drawing are also subjected to addition reading at the same tone timing. R and G pixels, which are sub-colors, of the lower stage of the regions Z3, Z4 are read.

  • Publication number: 20160205359
    Abstract: The present technology relates to a solid state imaging device, an imaging device, and an electronic device capable of improving color resolution and luminance resolution, and reducing a false color. White W as a luminance main component is arranged in a checkered pattern. A unit of two green G pixels are arranged in each of rows and columns in a range of 8 pixels×8 pixels to increase uniformity of green G and thereby improve resolution of green G as illustrated in an arrangement example 176. Moreover, rows and columns containing blue B are separated from rows and columns containing red R to improve resolution as illustrated in arrangement examples 174 and 175. Furthermore, white W, blue B, and red R are so arranged as to surround isolated point pixels corresponding to lost pixels of white W, blue B, and red R for easy interpolation as illustrated in arrangement examples 173 through 175. The present technology is applicable to a solid state imaging device.

  • Patent number: 8948506
    Abstract: A device and method for generating RGB arrangement data from an imaging signal by a photograph imaging device having an RGBW arrangement are provided. An edge detection unit analyzes an output signal in the RGBW arrangement from the imaging device, and thus obtains edge information corresponding to each pixel, and a texture detection unit generates texture information. Furthermore, a parameter calculation unit performs an interpolation process of converting an application pixel position according to the edge direction corresponding to a conversion pixel. A blend process unit inputs a parameter which the parameter calculation unit generates, edge information and texture information, and determines a conversion pixel value by performing a blend process by changing a blend ratio of the parameter which the parameter calculation unit calculates, according to the edge information corresponding to the conversion pixel and the texture information.
