An image processing device, which includes processing circuitry configured to cause the image processing device to first detect a first bad pixel based on first image data, correct the first bad pixel based on first values of first peripheral pixels in response to the first detection to obtain a first correction result, the first peripheral pixels being peripheral to the first bad pixel, second detect the first bad pixel and a second bad pixel based on the first image data, the second bad pixel being adjacent to the first bad pixel, correct the second bad pixel based on second values of second peripheral pixels to obtain a second correction result, the second peripheral pixels being peripheral to the second bad pixel, and correct the first bad pixel by using the first correction result stored in a buffer in response to the second detection.

Processor, image processing device including the same, and control method of image processing device

Disclosed is an electronic device which includes a processing block, a crosstalk compensation block, and a dark level compensation block. The processing block receives image data from an active pixel region of an image sensor and performs pre-processing on the image data. The crosstalk compensation block performs crosstalk compensation on the pre-processed image data. The dark level compensation block performs the crosstalk compensation on dark level data received from an optical black region of the image sensor and performs a subtraction operation on the crosstalk-compensated image data and the crosstalk-compensated dark level data.

Device and method for compensating crosstalk of image sensor having multi-color filter array

An image processing device includes a memory and a color correction circuit. The memory stores first correction information that used for correcting first pixel values among a plurality of pixel values. The plurality of pixel values are received from an auto-focus image sensor including first pixels configured to detect a phase difference and second pixels configured to detect an image. The first pixel values are obtained from the first pixels and correspond to a first color. The first correction information is used for correcting the first pixel values to correspond to a second color different from the first color. The color correction circuit receives first image frame data including the plurality of pixel values from the auto-focus image sensor, loads the first correction information from the memory, and generates first corrected image frame data by correcting the first pixel values included in the first image frame data to correspond to the second color based on the first correction information.
