Abstract: A method and apparatus for increasing a dynamic range of an image by using a first electronic shutter and a second electronic shutter of a camera is provided. The method includes initiating exposure of an image sensor by moving a first electronic front curtain according to a first control pulse signal of the first electronic shutter; moving a second electronic front curtain with respect to at least one pixel of the image sensor according to a second control pulse signal of the second electronic shutter; blocking the exposure of the image sensor by moving a mechanical rear curtain included in the camera; and acquiring, after blocking the exposure, a long exposure image using the first electronic front curtain and a short exposure image using the second electronic front curtain.

Abstract: An electronic device includes a lens part that receives light from a subject, an image sensor that receives the light of the lens part from a group of pixels arranged two-dimensionally, and an processor that processes an image signal of the image sensor. The image sensor performs a read-out operation at a speed to prevent blurring of an image. The processor temporarily stores image data by the read-out operation in a memory, loads a plurality of images stored in the memory to generate an image, of which the number of bits is expanded compared with the image signal of the image sensor, and performs gamma processing on the image, of which the number of bits is expanded, to generate an image compressed to the same number of bits as the image signal of the image sensor.

Abstract: An electronic device is provided. The electronic device includes a first camera configured to include a first image sensor, a second camera configured to include a second image sensor, and a processor. The processor allows a pixel array of the first image sensor to have a difference of a first exposure start timing in units of at least one row and obtains a first image based on a first exposure period and a first read-out speed using the first camera, allows a pixel array of the second image sensor to have a difference of a second exposure start timing in units of at least one row and obtains a plurality of second images based on a second exposure period and a second read-out speed using the second camera, and generates a third image by synthesizing at least some of the plurality of second images.
