An image signal processor includes a gradation detection module configured to receive a pixel signal from an external device and a correction module configured to receive the pixel signal. The correction module is connected to the gradation detection module. The gradation detection module is configured to estimate a gradient of the pixel signal, correct the pixel signal based on the gradient to generate a corrected pixel signal, calculate a first variance value based on the pixel signal, calculate a second variance value based on the corrected pixel signal, calculate a gradation probability value based on a comparison result between the first variance value and the second variance value, and generate a gradation map as information about the gradation probability value of the pixel signal. The correction module is configured to correct the pixel signal based on the gradation map.

Image signal processor, method for operating image signal processor and image sensing device

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&#xd7;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&#xd7;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.
