Reception apparatus, reception method, and image processing system
The present disclosure relates to a reception apparatus, a reception method, and an image processing system that can suppress a reduction in resolution of an image that a surgery operator wants to see at a high resolution while responding to an increase in the number of connections of medical equipment that supply images. In the previous stage of a transmission path such as PCIe, images are acquired from a plurality of pieces of medical equipment, a compression method is selected for each type of image, and the image is compressed and output to the transmission path. Therefore, among YCbCr signals, e.g., of a CT image or an X image, an image that does not require CbCr signals is compressed as the Y signal only, and an image that requires a high-resolution image such as an operative field image is transmitted without being compressed. Therefore, it is possible to suppress compression of the band of a transmission path such as PCIe. The present disclosure can be applied to an intra-hospital image processing system.
