Abstract
An electronic device is provided and includes an image sensor including a plurality of unit pixels including a first unit pixel and a second unit pixel, the first unit pixel including a first micro-lens, a first color filter disposed under the first micro-lens, and a first photodiode-array disposed under the first color filter and including a plurality of photodiodes arranged in a same number of columns and rows as each other, and the second unit pixel including a second micro-lens, a second color filter disposed under the second micro-lens and having a different color from that of the first color filter, and a second photodiode-array disposed under the second color filter and including a plurality of photodiodes arranged in a same number of columns and rows as each other; and a processor operatively coupled with the image sensor, wherein the processor is configured to identify a mode corresponding to an auto-focus function; if the mode is identified as a first mode, perform the auto-focus function based at least in part on comparing a first combined signal generated by combining signals obtained from a first column of the first photodiode-array with a second combined signal generated by combining signals obtained from a second column of the first photodiode-array; if the mode is identified as a second mode different from the first mode, perform the auto-focus function based at least in part on comparing the first combined signal with the second combined signal and comparing a third combined signal generated by combining signals obtained from a first row of the first photodiode-array with a fourth combined signal generated by combining signals obtained from a second row of the first photodiode-array; and generate an image signal based at least in part on signals obtained from the first unit pixel and the second unit pixel while the auto-focus function is performed according to a one of the first mode and the second mode.
