  • ELECTRONIC APPARATUS AND OPERATING METHOD OF THE ELECTRONIC APPARATUS
    Publication number: 20230050561
    Abstract: An electronic apparatus includes: an image sensor for acquiring pixel values of first pixels sensed during a first exposure time and second pixels sensed during a second exposure time longer than the first exposure time; and a controller for outputting an output image acquired based on pixel values of the first pixels and a corrected saturated pixel value obtained by correcting a pixel value of a saturated pixel having a pixel value exceeding a threshold value among the second pixels, using a pixel value of at least one first pixel having a distance closest to a position of the saturated pixel among the first pixels.

  • Image signal processor and image processing system
    Patent number: 11553146
    Abstract: An image processing system includes: an image sensor suitable for generating an RYYB (Red Yellow Yellow Blue) bayer image by applying an RYYB color filter array; an interpolation logic suitable for generating a Y image at a position of an R image portion in the RYYB bayer image by interpolating a YY image portion in the RYYB bayer image; and a guided filtering logic suitable for guided-filtering the R image portion in the RYYB bayer image by using, as a guide image, the Y image at the position of the R image portion.

  • APPARATUS AND METHOD FOR IMPROVING IMAGE QUALITY BASED ON DEFINITION AND CHROMA
    Publication number: 20120170845
    Abstract: An apparatus and method for improving image quality based on definition and chroma are provided. The method includes analyzing an input image; calculating a quantified definition value and a quantified chroma value of the input image; determining a definition parameter corresponding to the quantified definition value and a chroma parameter corresponding to the quantified chroma value; and applying the determined definition parameter and the determined chroma parameter to a frame of the input image.
