A first communication apparatus includes a communication unit configured to communicate with a second communication apparatus, an image processing unit, and a control unit. The control unit generates the first image data from the RAW image data received from the second communication apparatus. In a case where the control unit determines that a performance of the second communication apparatus is equal to or higher than a predetermined performance, the control unit transmits the first image data to the second communication apparatus. In a case where the control unit determines that a performance of the second communication apparatus is lower than the predetermined performance, the control unit generates the second image data from the first image data, and transmits the generated second image data to the second communication apparatus.
