Abstract: Disclosed is an electronic device. The electronic device according to an embodiment includes a camera, a sensor obtaining first motion information about motion of the electronic device, and a processor electrically connected to the camera and the sensor. The processor is configured to receive a plurality of image frames from the camera, to generate second motion information by applying a filter for a specified frequency band to the first motion information, to generate one or more image frames, in each of which at least partial motion of the motion is compensated based on the second motion information, from the at least part of image frames, and to display the one or more image frames through a display operatively connected to the electronic device. The receiving includes obtaining the first motion information about at least part of image frames among the plurality of image frames. Moreover, various embodiment grasped through the disclosure are possible.

Abstract: An object of the present disclosure is to restore a quantization error of an image signal only by expanding the number of bits of a reconstructed image compared to the number of bits of an input image without expanding the number of bits in an image signal processing process. An image display apparatus may include a signal inputter configured to receive an input image signal; an image signal processor configured to perform image processing of the input image signal, to identify a type of image processing by comparing the input image signal and the processed image signal, to obtain restoration information of the processed image signal according to the identified image processing type, and to restore an error of the processed image signal by performing remapping of the processed image signal using the restoration information; and an outputter configured to output the image signal in which the error is restored.

Abstract: An electronic device is disclosed. Moreover, various embodiment found through the disclosure are possible. The electronic device may include a camera module including an optical image stabilizer, a motion sensor, a processor electrically connected to the camera module and the motion sensor. The processor may be configured to obtain first motion information corresponding to shaking of the electronic device through the motion sensor, while at least partially obtaining an image frame, determine second motion information, which corresponds to motion of a lens or an image sensor included in the camera module, from the first motion information, using attribute information and a frequency pass filter of the optical image stabilizer, and perform digital image correction, based on the first motion information and the second motion information.
