  • Photometric device, photometric method, program, and capturing device
    Patent number: 10908478
    Abstract: A subject region discrimination unit 11 discriminates a desired subject region on the basis of ranging information. A subject photometric region setting unit 12 performs image signal processing of the desired subject region that is discriminated by the subject region discrimination unit 11, and sets a photometric region corresponding to the subject region after the processing as a subject photometric region. A photometric value calculation unit 13 calculates a photometric value of the desired subject region by using a photometric value of the subject photometric region that is set by the subject photometric region setting unit 12. For this reason, it is possible to accurately acquire the photometric value with respect to the desired subject region, and it is possible to perform optimal exposure control with respect to the desired subject region by using the photometric value that is calculated by the photometric value calculation unit.
