Video system, video processing method, program, camera system, and video converter

A video processing method, comprising:

• generating, by a first processing circuit in a camera system, from a pixel signal generated by an image pickup unit that captures a subject and obtains a pixel signal thereof, a first video signal in which one or more pixels in the pixel signal are adjusted on a basis of a first image adjustment parameter;
• generating, by the first processing circuit in the camera system, from the pixel signal generated by the image pickup unit, a second video signal in which one or more pixels in the pixel signal are adjusted on a basis of a second image adjustment parameter different from the first image adjustment parameter;
• transmitting, by the first processing circuit in the camera system, transmission information obtained by adding the first image adjustment parameter and the second image adjustment parameter to the second video signal via a first transmission channel;
• receiving, by a video converter, the transmission information via the first transmission channel;
• generating, by a second processing circuit in the video converter, on a basis of the second image adjustment parameter included in the transmission information, a restoration pixel signal by inverse-transforming the second video signal included in the transmission information;
• and
• performing, by the second processing circuit in the video converter, adjustment processing corresponding to the first video signal on the restoration pixel signal on a basis of the first image adjustment parameter included in the transmission information to generate an output video signal corresponding to the first video signal,
• wherein the first video signal is an SDR (Standard Dynamic Range) video, and the second video signal is an HDR (High Dynamic Range) video.

• generating, from the pixel signal generated by the image pickup unit, a second video signal in which one or more pixels in the pixel signal are adjusted on a basis of a second image adjustment parameter different from the first image adjustment parameter;
• transmitting transmission information obtained by adding the first image adjustment parameter and the second image adjustment parameter to the second video signal via a first transmission channel;
• receiving the transmission information via the first transmission channel
• generating, on a basis of the second image adjustment parameter included in the transmission information, a restoration pixel signal by inverse-transforming the second video signal included in the transmission information;
• and
• performing adjustment processing corresponding to the first video signal on the restoration pixel signal on a basis of the first image adjustment parameter included in the transmission information to generate an output video signal corresponding to the first video signal,
• wherein the first video signal is an SDR (Standard Dynamic Range) video, and the second video signal is an HDR (High Dynamic Range) video.
