Claim 4:
5. A transmission system comprising:
a transmission device that includes a processor that performs shading correction processing on image data of a region of interest (ROI) in a captured image on a basis of coordinate information of the ROI, and transmission circuitry that sends the image data of the ROI subjected to the shading correction processing as payload data and sends ROI information as embedded data; and
a reception device that includes reception circuitry that receives a transmission signal in which image data of an image included in the ROI is included in the payload data and the ROI information is included in the embedded data, wherein
the transmission device generates, by the processor, coordinates of each pixel of the image data of the ROI in the captured image as the coordinate information on a basis of coordinates of an upper-left end portion of the ROI, and amplifies a luminance for each pixel of the generated image data of the ROI, and
the transmission device includes a correction value table in which a correction value used for the shading correction processing is held, and amplifies a luminance of the image data of the ROI by using the correction value acquired from the correction value table on a basis of the coordinate information.
