摘要

An electronic device is provided. The electronic device includes a camera module including a lens assembly and an image sensor, a display, and a processor. At least one pixel of the image sensor includes a first sub-pixel, a second sub-pixel, a third sub-pixel, and a fourth sub-pixel. The first sub-pixel may be covered by a first micro lens, the second sub-pixel may be covered by a second micro lens, and the third sub-pixel and the fourth sub-pixel may be covered by a third micro lens. The processor obtains a light reflected from an external object, generates depth data, generates pixel data generates an image based on the pixel data, outputs the image, and moves one or more lenses based on the depth data.

說明書

In operation 830, the processor 450 may generate pixel data on the at least one pixel based on the pieces of data respectively obtained from the first sub-pixel PD1, the second sub-pixel PD2, the third sub-pixel PD3, and the fourth sub-pixel PD4, by using the image sensor 415. For example, in the first output mode, by using the image sensor 415, the processor 450 may generate pixel data on the at least one pixel 210, by binning the data obtained from the first sub-pixel PD1, the second sub-pixel PD2, the third sub-pixel PD3, and the fourth sub-pixel PD4 and performing analog-to-digital conversion on the binned data. For another example, in the second output mode, by using the image sensor 415, the processor 450 may generate pixel data on a sub-pixel unit, by performing analog-to-digital conversion on the data obtained from the first sub-pixel PD1, the second sub-pixel PD2, the third sub-pixel PD3, and the fourth sub-pixel PD4.

In operation 840, the processor 450 may display an image generated based on the pixel data through the display (e.g., the display 430 of FIG. 4). For example, the processor 450 may perform color interpolation on image data such that each pixel of the image data includes “R” information, “G” information, and “B” information and may convert the color-interpolated image data to correspond to a specified format (e.g., a YUV format). The processor 450 may generate an image based on the converted image data and may display the generated image through a display (e.g., the display 430 of FIG. 4).
