AI Technical Summary
Technical Problem
Existing photography techniques that increase exposure by reducing optical zoom magnification and opening the aperture may not be optimal, especially when resolution is required, leading to decreased visibility or increased noise.
Method used
A calculation means estimates the subject size in a captured image and calculates appropriate aperture and optical zoom magnifications to maintain proper exposure, adjusting these settings based on the subject's size, gain, or type to optimize image quality.
Benefits of technology
Enables proper exposure while maintaining subject size and visibility, reducing noise, and optimizing image quality under varying conditions.

Abstract
To provide technology that enables proper exposure. [Solution] The size of the subject in the captured image is estimated using the optical zoom magnification calculated to achieve proper exposure, and the aperture value and optical zoom magnification are calculated based on the estimated size. Exposure is controlled according to the calculated aperture value and optical zoom magnification.
