Electronic device generating image data and converting the generated image data and operating method of the electronic device

An operating method of an electronic device which includes an image sensor and a processor, the operating method comprising:

• capturing, at the image sensor, a target to generate first image data;
• performing, at the processor, directional interpolation on a first area of the first image data to generate first partial image data;
• performing, at the processor, upscale on a second area of the first image data to generate second partial image data;
• performing, at the processor, the directional interpolation on a third area of the first image data to generate third partial image data;
• performing, at the processor, the upscale on the third area of the first image data to generate fourth partial image data;
• and
• combining, at the processor, the first partial image data and the second partial image data to generate second image data.

An electronic device comprising:

• an image sensor;
• and
• a processor configured to receive first image data from the image sensor and to convert and output the first image data as second image data,
• wherein the image sensor includes:
• a lens;
• a color filter array including color filters configured to pass specific frequency components of a light incident through the lens;
• a pixel array including pixels configured to convert intensities of the specific frequency components of the light passing through the color filters into analog signals;
• and
• an analog-to-digital converter configured to convert the analog signals into digital signals and to output the digital signals to the image sensor,
• wherein the processor includes:
• a first memory configured to receive the first image data;
• location information storage configured to store location information, wherein the location information includes a first area having a resolution level higher than a first threshold level and a second area having a resolution level lower than or equal to a second threshold level;
• a first conversion circuit configured to perform a first conversion on first input data and to output a result of the first conversion as first partial image data;
• a second conversion circuit configured to perform a second conversion on second input data and to output a result of the second conversion as second partial image data;
• a selection circuit configured to output the first image data in a form of the first input data, the second input data, or the first input data and the second input data, based on the location information;
• and
• a mixer configured to combine the first partial image data and the second partial image data to generate the second image data, in response to a selection signal from the selection circuit, and
• wherein, when the first partial image data and the second partial image data are output together, the mixer is configured to perform alpha blending on the first partial image data and the second partial image data.
