ELECTRONIC DEVICE INCLUDING IMAGE SENSOR AND OPERATING METHOD THEREOF
A method and an electronic device are provided in which, in a first unit pixel of an image sensor, a first analog-to-digital conversion (ADC) is performed by reading out a first photodiode (PD) group and a second PD group that is adjacent to the first PD group in a first direction. A second ADC is p...

| description | A method and an electronic device are provided in which, in a first unit pixel of an image sensor, a first analog-to-digital conversion (ADC) is performed by reading out a first photodiode (PD) group and a second PD group that is adjacent to the first PD group in a first direction. A second ADC is performed by reading out a third PD group that is adjacent to the first PD group in a second direction. The second direction is perpendicular to the first direction. A third ADC is performed by reading out a fourth PD group that is adjacent to the second PD group in the second direction. A first phase difference in the second direction is detected based on the first ADC, the second ADC, and the third ADC. A second phase difference in the first direction is detected based on the second ADC and the third ADC. |
