Electronic device for providing image processing service through network

An electronic device comprising:

• a communication module;
• and
• a processor operatively connected to the communication module and configured to transmit and receive data to and from a first external electronic device through the communication module, and
• wherein the processor is configured to:
• receive, from the first external electronic device, a preview image, wherein the preview image comprises application of a first image processing on a preview source image associated with an image photographed through a camera of a second external electronic device;
• request a second image processing related to the preview image to the first external electronic device;
• and
• receive a modified preview image obtained, wherein the modified preview image comprises application of the second image processing on the preview image,
• wherein a still source image and the preview source image are obtained by the first external electronic device at substantially a same time.

A non-transitory computer-readable medium storing a plurality of instructions, wherein execution of the plurality of instructions by a processor causes the processor to perform a plurality of operations comprising:

• receiving a preview source image from a first external electronic device, wherein the preview source image is associated with an image photographed through a camera of the first external electronic device;
• performing a first image processing on the preview source image, thereby resulting in a preview image;
• transmitting the preview image to a second external electronic device and a third external electronic device;
• receiving a request for second image processing from the second external electronic device;
• transmitting a first modified preview image obtained by performing the second image processing on the preview image to the second external electronic device in response to the request;
• receiving a request for third image processing form the third external electronic device;
• and
• transmitting a second modified preview image obtained by performing the third image processing on the preview image to the third external electronic device,
• requesting, to first external electronic device, a still source image associated with the photographed image when a request for a still image corresponding to the first modified preview image is received from the second external electronic device, wherein the still source image and the preview source image are obtained by the first external electronic device at substantially a same time;
• and
• transmitting, to the second external electronic device, a first modified still image obtained by performing the second image processing on the still source image.
