Provided is an image processing system capable of coping with data which is obtained in a new color filter array, and making full use of the performance of a receiving-side device by reducing the influence of a difference in the performance of the receiving-side device on an image quality. An image processing system 100 includes a transmitting-side device 101 and a receiving-side device 102. The transmitting-side device 101 generates intermediate data by preprocessing RAW data, generates three-plane color data by processing synchronization of the intermediate data, and outputs placement information for specifying pixel positions corresponding to the three-plane color data and the intermediate data. The receiving-side device 102 restores the intermediate data using the three-plane color data and the placement information from the transmitting-side device 101, and generates the three-plane color data from the restored intermediate data.
