Abstract
There is provided a control device including a setting unit configured to set a first control value used for performing exposure control of a first pixel group and a second control value used for performing exposure control of a second pixel group, the first pixel group and the second pixel group being disposed in a single imaging surface. The setting unit sets the first control value and the second control value to different values before a predetermined photometric process is executed.
Claims20
A control device comprising:
- setting circuitry configured to set a first control value used for performing exposure control of a first pixel group and including a first gain, and a second control value used for performing exposure control of a second pixel group and including a second gain, the first pixel group and the second pixel group being disposed in a single imaging surface,
- wherein the setting circuitry sets the first control value and the second control value to different values before a predetermined photometric process is executed, and
- wherein the setting circuitry sets the first gain and the second gain to different values before the predetermined photometric process is executed.
A control method comprising:
- setting a first control value used for performing exposure control of a first pixel group, the first control value including a first grain;
- setting a second control value used for performing exposure control of a second pixel group to a value different from the first control value, the second control value including a second gain, the first pixel group and the second pixel group being disposed in a single imaging surface, the first control value and the second control value being set before a predetermined photometric process is executed;
- and
- setting the first gain and the second gain to different values before the predetermined photometric process is executed.
