1. An image pickup system, comprising:
processing circuitry configured to:
generate correlation information between a first dynamic range and a second dynamic range based on predetermined relation information, the correlation information indicating a correlation between the first dynamic range and the second dynamic range,
generate a first video signal by applying a first detail processing to a first pixel signal, the first video signal having the first dynamic range, and
generate a second video signal by applying a second detail processing to a second pixel signal, the second video signal having the second dynamic range,
wherein a first gain adjustment of the first video signal and a second gain adjustment of the second video signal are set according to the correlation information, and
wherein the first pixel signal is obtained from an image sensor and the second pixel signal is obtained from an inverse transformation of the first video signal, the inverse transformation being performed by inverse transformation circuitry.
