Abstract: An image sensor having improved image quality is provided. The image sensor includes a first array of pixels, a second array of pixels, and a binning module. The first array of pixels has a color pattern formed in an n×m array and includes at least first-color pixels, second-color pixels, and third color-pixels. The second array of pixels is adjacent to the first array of pixels and has the same color pattern formed in an n×m array as the first array of pixels, to include at least first-color pixels, second-color pixels, and third color-pixels. The binning module is configured to, for a sensed image: perform binning on the first-color pixels of the first array, the first-color pixels of the second array, the second-color pixels of the first array, and the third-color pixels of the second array, and not perform binning on the third-color pixels of the first array, and not perform binning on the second-color pixels of the second array

Abstract: An image signal processing method includes: detecting a high frequency component in an input image received from an image sensor; calculating a ratio of the detected high frequency component; reconstructing a high frequency image based on the calculated ratio; and outputting an output image by combining the reconstructed high frequency image with a non-high frequency image of the input image.

Abstract: An image processing device and an image processing method are provided. The image processing device includes an image sensor configured to sense and output a raw image and an image signal processor configured to compare pixel values of the raw image with a reference level to classify a saturation color image and a non-saturation color image, calculate a first fixed pattern noise from the saturation color image, calculate a second fixed pattern noise from the non-saturation color image, generate a final fixed pattern noise by combining the first fixed pattern noise with the second fixed pattern noise, and output a revised image by subtracting the final fixed pattern noise from the raw image.

Abstract: An image sensor is provided. The image sensor includes: a pixel array including a plurality of pixel groups arranged in a Bayer pattern; a row driver connected to a row of the pixel array; and a readout circuit configured to sample a pixel signal from the pixel array, to compare the sampled pixel signal with a ramp signal, and to generate a digital image signal based on a comparison of the pixel signal and the ramp signal. A pixel group of the plurality of pixel groups includes sixteen sub-pixels arranged in a 4×4 array, the 4×4 array includes a plurality of readout areas, and the plurality of readout areas are activated alternately with each other. In each of the plurality of readout areas in the pixel group, micro lenses are arranged asymmetrically with each other.
