Abstract: An image correction method is provided. The image correction method includes receiving an input image from a first camera; receiving a guide image from a second camera; generating a corrected image by performing image correction on the input image using the guide image, the image correction being performed by an image generation unit having a pre-learned image generation parameter learned using a training image; generating a quality value of the corrected image by an image evaluation unit having an pre-learned image evaluation parameter learned using the training image; and performing the image correction on the corrected image again when the quality value of the corrected image is less than a set value, and outputting the corrected image as a final image when the quality value of the corrected image is greater than the set value.

Abstract: A method includes acquiring a current frame, a noise dispersion map for the current frame, and a first denoised frame for a previous frame; generating a weighted first denoised frame based on the noise dispersion map, the current frame, and the first denoised frame using a first neural network; generating an initial fused image based on the current frame and the weighted first denoised frame using a second neural network; and generating a second denoised frame for the current frame based on the initial fused image using a third neural network.

Abstract: An electronic device includes an image sensor configured to receive light that is incident on the electronic device through a lens and generate image data, a gyroscope configured to generate rotation motion data of the electronic device, and an image stabilizer configured to generate translation motion data of the electronic device based on the image data received from the image sensor and to generate a stabilized image by compensating for a motion of the electronic device while capturing the image, such as vibration of a handheld device. The stabilized image is generated based on filtered translation motion data obtained by performing a first filtering operation on the translation motion data and filtered rotation motion data obtained by performing a second filtering operation on the rotation motion data received from the gyroscope.

Abstract: An imaging apparatus and an imaging method are provided. The imaging apparatus includes an imager configured to output image data for a subject, a motion detector configured to detect motion of the imaging apparatus, and a controller configured to control the imager to suspend output of the image data in response to the motion detector detecting the motion.
