Abstract: An electronic device includes a camera and a processor. The processor is configured to: obtain a first image from the camera with respect to an external object, move a lens device depending on a specified amount of movement using a lens driver, obtain a second image corresponding to a position to which the lens device moves with respect to the external object, determine a first partial area of the first image corresponding to a specified portion of the external object, determine a second partial area of the second image corresponding to the first partial area based on the first partial area and the specified movement amount, determine a focus position with respect to the lens device based on a defocus difference between the first partial area and the second partial area and the specified movement amount, and move the lens device to the focus position using the lens driver.

Abstract: An electronic device includes a lens part that receives light from the outside, an image sensor that changes the received light to electronic image data, and an image processing unit that processes the image data. If a saturated pixel is included in the image data, the image processing unit measures the amount of light of the saturated pixel by using an increasing or decreasing value of brightness of a plurality of unsaturated pixels around the saturated pixel.

Abstract: An electronic device includes a first camera that obtains a first image, a second camera that obtains a second image having a disparity with the first image, a memory that stores a first calibration parameter, and a processor that calibrates at least one of the first image and the second image by using the first calibration parameter and composes the first image and the second image. The processor is configured to collect, if a specified event occurs, images obtained from the first camera and the second camera after the specified event occurs and store the collected images in the memory, to compute a second to calibration parameter based on the images obtained after the specified event occurs, if a specified condition is satisfied, and to update the first calibration parameter with the second calibration parameter.

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 includes an image sensor including a pixel array, and an image processor electrically connected with the image sensor. The image processor is configured to acquire a first image of a subject generated based on a first group of optical paths and to acquire a second image of the subject generated based on a second group of optical paths, the second group of optical paths having a phase difference with the first group of optical paths from the pixel array, to normalize pixel values included in the first image and pixel values included in the second image in units of a pixel, and to verify a light source of light reflected by the subject or a light source of light produced from the subject, based on a parameter associated with changes in the normalized pixel values.
