  • Patent number: 9277146
    Abstract: An image sensor includes a pixel array having a plurality of layers and a control unit. Each of the plurality of layers including pixels having a photoelectric conversion element and a transmission transistor therein. The photoelectric conversion element is configured to collect charges during an associated charge collection time period and the transmission transistor is configured to transmit the charges to a respective floating diffusion node at an end of the charge collection time period. The control unit configured to individually instruct the transmission transistors associated with different ones of the layers to transmit the charges to the respective floating diffusion nodes such that the charge collection time periods associated with the photoelectric conversion elements implemented in at least two of the layers differs in length.

  • Patent number: 8836827
    Abstract: A method of processing image signals comprises determining whether each of multiple units of input pixel data received from an image sensor is bad pixel data generated by a bad pixel of the image sensor or normal pixel data generated by a normal pixel of the image sensor, and performing interpolation to generate image data corresponding to the bad pixel using only normal pixel data and omitting bad pixel data.

  • Publication number: 20140132808
    Abstract: A method for interpolating a color includes interpolating, in a first pixel of a first color, a first pixel value based on pixel values of pixels adjacent to the first pixel, skipping an interpolation on a second pixel of a second color corresponding to the first pixel of the first color; and generating an image based on the interpolated first pixel value and an uninterpolated pixel value of the second pixel.

  • Publication number: 20140118579
    Abstract: An image processing apparatus includes a first pixel, a digitization unit, and a correction unit. The first pixel includes a first photoelectric conversion layer for outputting a first electrical signal in response to received incident light, including light of a first color, light of a second color, and light of a third color; and a second photoelectric conversion layer disposed under the first photoelectric conversion layer and for outputting a second electrical signal in response to light transmitted through the first photoelectric conversion layer. The digitization unit generates first original data by digitizing the first electrical signal and generates second original data by digitizing the second electrical signal. The correction unit generates first corrected data corresponding to the light of the first color and second corrected data corresponding to the light of the second color, by respectively correcting the first original data and the second original data.
