    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 example electronic device 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.

    Abstract: An electronic device is disclosed. Moreover, various embodiment found through the disclosure are possible. An electronic device may include a lens assembly including, one or more lenses, an image sensor, an image stabilizer, and a processor. The lens assembly may be arranged to from a first angle between an optical axis of at least some lenses of the one or more lenses, and a surface of the image sensor. The processor may be configured to change an angle of the lens assembly through the image stabilizer in response to shaking of the electronic device, obtain an image through the image sensor, in a state that the angle of the lens assembly is changed, correct, based at least on the first angle and a second angle corresponding to the changed angle of the lens assembly, at least a portion of the image, which is distorted, by the second angle, and display the corrected image through a display electrically connected with the electronic device.
