    Abstract: An electronic device is provided and includes an image sensor including a first unit pixel including a first micro-lens and a plurality of first photodiodes facing each other with a first color filter interposed between the plurality of first photodiodes, and a second unit pixel including a second micro-lens and a plurality of second photodiodes facing each other with a second color filter interposed between the plurality of second photodiodes, a camera module including the image sensor, and a processor operatively connected with the image sensor. The first unit pixel includes a first photodiode, a second photodiode, a third photodiode, and a fourth photodiode, which are disposed in a square shape such that a horizontal number of photodiodes is identical to a vertical number of photodiodes. The second unit pixel includes a fifth photodiode, a sixth photodiode, a seventh photodiode, and an eighth photodiode, which are disposed in a square shape such that a horizontal number of photodiodes is identical to a vertical number of photodiodes. The image sensor identifies an operation setting and an external environmental condition of the camera module and, upon identifying that the operation setting is a preview mode and the external environmental condition is a high luminous environment, identifies a first area signal corresponding to a signal of the first photodiode and the second photodiode, which are concatenated with each other and included in the first unit pixel, and identifies a second area signal that corresponds to a signal of the fifth photodiode, included in the second unit pixel, corresponding to a location of the first photodiode and the sixth photodiode, included in the second unit pixel, corresponding to a location of the second photodiode, and forms first auto focus (AF) information based on the first area signal and the second area signal.

    Abstract: An electronic device including an image sensor and a processor may be provided. The image sensor may provide, in a first mode, to the at least one processor, first image data may be obtained by outputting data input to a unit pixel of the image sensor with a first conversion gain, the first image data may have a first number of bits. The image sensor may provide, in a second mode, to the at least one processor, second image data may be obtained by outputting data input to the unit pixel of the image sensor with the first conversion gain and a second conversion gain. The second conversion gain may be lower than the first conversion gain. The second image data may have a second number of bits which may be larger than the first number of bits.

    Abstract: Disclosed is an electronic device including an image sensor including a lens, a pixel array configured to convert light collected through the lens into an electric signal and to output the electric signal, a readout circuit configured to convert electric signals sequentially received for each row of the pixel array into pixel data and to output the pixel data, a memory, and a controller configured to control the pixel array, the readout circuit and the memory, and a processor electrically connected to the image sensor. The controller is configured to generate a frame by integrating the pixel data sequentially received from the readout circuit, generate a profile regarding flickering of the collected light using the generated frame and another frame generated prior to the generated frame, and store the generated profile in the memory, obtain a profile set including profiles corresponding to a plurality of frames from the memory, and transfer the generated frame and the obtained profile set to the processor.
