Abstract
A control method for generating a high quality HDR image is provided. A control device of the technique of this disclosure is a control device configured to control an image capturing element capable of controlling an exposure condition for each of areas, the device including: an acquisition unit configured to acquire an exposure value map obtained by preliminary exposure using the image capturing element; and a setting unit configured to set the exposure condition including a shutter speed and an ISO sensitivity for each of the areas based on the exposure value map.
Claims17
A device configured to control an image capturing element capable of controlling an exposure condition for each of areas in an image, the device comprising one or more processors and one or more memories, the one or more processors and one or more memories being configured to function as a plurality of units comprising:
- a setting unit configured to set the exposure condition including a shutter speed and an ISO sensitivity for each of the areas;
- a capturing unit configured to capture the image based on the set exposure condition;
- and
- a correction unit configured to correct the exposure condition for each of the areas based on a ratio of priority of the shutter speed and the ISO sensitivity of the exposure condition before capturing the image by the capturing unit.
A control method for controlling an image capturing element capable of controlling an exposure condition for each of areas in an image, the control method comprising:
- a setting step of setting a shutter speed and an ISO sensitivity for each of the areas;
- a capturing step of capturing the image based on the exposure condition;
- and
- a correction step of correcting the exposure condition for each of the areas based on a ratio of priority of the shutter speed and the ISO sensitivity before capturing the image.
A non-transitory computer-readable storage medium storing a program for causing a computer to execute each step in a control method for controlling an image capturing element capable of controlling an exposure condition for each of areas in an image, the method comprising:
- a setting step of setting a shutter speed and an ISO sensitivity for each of the areas;
- and
- a correction step of correcting the exposure condition for each of the areas based on a ratio of priority of the shutter speed and the ISO sensitivity before capturing the image.
