Abstract
An imaging apparatus capable of capturing two images which may not be obtained by the general HDR imaging by simultaneously capturing two images of different exposures by changing exposure change rates of a low exposure image and a high exposure image is provided. The imaging apparatus includes a calculation unit configured to calculate a first exposure for obtaining a first image included in the plurality of images under a first condition and calculate a second exposure for obtaining a second image included in the plurality of images under a second condition which is different from the first condition, and a setting unit configured to set an exposure for obtaining the first and second images based on the first and second exposures calculated by the calculation unit.
Claims20
An imaging apparatus including an imaging element which outputs a plurality of images for each imaging cycle, the imaging apparatus comprising:
- a calculation unit configured to calculate a first exposure for obtaining a first image included in the plurality of images under a first condition and calculate a second exposure for obtaining a second image included in the plurality of images under a second condition which is different from the first condition;
- and
- a setting unit configured to set an exposure for obtaining the first and second images based on the first and second exposures calculated by the calculation unit.
A method for controlling an imaging apparatus including an imaging element which outputs a plurality of images for each imaging cycle, the method comprising:
- calculating a first exposure for obtaining a first image included in the plurality of images under a first condition and calculating a second exposure for obtaining a second image included in the plurality of images under a second condition which is different from the first condition;
- and
- setting an exposure for obtaining the first and second images based on the calculated first and second exposures.
An imaging element which outputs a plurality of images for each imaging cycle, the imaging element comprising:
- a calculation unit configured to calculate a first exposure for obtaining a first image included in the plurality of images under a first condition and calculate a second exposure for obtaining a second image included in the plurality of images under a second condition which is different from the first condition;
- and
- a setting unit configured to set an exposure for obtaining the first and second images based on the first and second exposures calculated by the calculation unit.
An imaging apparatus including an imaging unit which outputs at least first and second images in each cycle in which images are consecutively obtained using a predetermined parameter, the imaging apparatus comprising:
- a calculation unit configured to calculate a first exposure for following a change of luminance of the first image which is consecutively obtained under a first calculation condition and calculates a second exposure for following a change of luminance of the second image which is consecutively obtained under a second calculation condition which is different from the first calculation condition;
- and
- a setting unit configured to set a parameter for obtaining the first and second images based on the first and second exposures calculated by the calculation unit to the imaging unit.
