Abstract
An object is to implement shading correction processing of some regions of interest (ROIs) cut from a captured image. A transmission device includes: a processing unit 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 a transmission unit that sends the image data of the ROI subjected to the shading correction processing as payload data and sends ROI information as embedded data.
Claims12
A transmission device comprising:
- a processor configured to perform 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;
- transmission circuitry configured to send the image data of the ROI subjected to the shading correction processing as payload data and to send ROI information as embedded data, wherein
- the processor uses at least coordinates of an upper-left end portion of the ROI as the coordinate information of the ROI,
- generates coordinates of each pixel of the image data of the ROI in the captured image on a basis of the coordinates of the upper-left end portion of the ROI, and
- amplifies a luminance for each pixel of the image data of the ROI on a basis of the generated coordinates of each pixel;
- a first counter that measures X coordinates of the ROI in the captured image starting from the coordinates of the upper-left end portion of the ROI;
- and
- a second counter that measures Y coordinates of the ROI in the captured image starting from the coordinates of the upper-left end portion of the ROI, wherein
- the processor generates the coordinates of each pixel of the image data of the ROI by using the first counter and the second counter.
