Method for transmitting image data and data associated with control of image capture, on basis of size of image data and size of data associated with control of image capture, and electronic device supporting same

A method for transmitting image data and data associated with control of image capture, the method comprising:

• receiving a signal for photographing an external object by a control circuit included in a sensor module including an image sensor;
• acquiring a plurality of pieces of raw image data for the external object using the image sensor by the control circuit;
• generating pixel information data associated with the image capture of a processor electrically connected to the image sensor and connected to the control circuit via an interface, using at least some of the plurality of acquired pieces of raw image data by the control circuit;
• generating compressed data obtained by compressing at least some of the plurality of pieces of raw image data;
• transmitting the pixel information data to the processor according to a transmission period specified by the processor or the control circuit;
• transmitting the compressed data to the processor;
• generating compressed pixel information data by compressing the pixel information data,
• wherein the transmitting of the pixel information data to the processor according to the specified transmission period comprises:
• transmitting the compressed pixel information data to the processor when a compression rate of the compressed pixel information data satisfies a specified compression rate;
• and
• transmitting uncompressed pixel information data to the processor when the compression rate does not satisfy the specified compression rate.
