Abstract
A controller of imaging device controls a imaging circuit so as to image a subject with gradation on a high-luminance side expanded relative to a previously prepared gradation characteristic serving as a reference, generates image data in a image processing circuit and stores the enhancement amount in a memory in association with the image data, and controls display-luminance of the display in accordance with the corresponding enhancement amount stored in the memory, in displaying the image data on the display.
Claims8
An imaging device, comprising:
- an imaging circuit which images a subject under a predetermined imaging condition and outputs imaging data;
- a display capable of enhancing display-luminance of image data more than a predetermined reference luminance;
- an image processing circuit which generates the image data to be displayed on the display from the imaging data;
- a memory which stores the image data;
- and
- a controller which obtains a distribution for each luminance from the image data, calculates an enhancement amount based on an expansion amount of gradation obtained corresponding to a percentage of high luminance, and controls the imaging condition in the imaging circuit and an enhancement amount of display-luminance in the display, wherein
- the controller controls the imaging circuit so as to image a subject with gradation on a high-luminance side expanded relative to a previously prepared gradation characteristic serving as a reference, generates image data in the image processing circuit and stores the enhancement amount in the memory in association with the image data, and controls display-luminance of the display in accordance with the corresponding enhancement amount stored in the memory, in displaying the image data on the display.
An imaging method of an imaging device including a display capable of enhancing display-luminance of image data more than a predetermined reference luminance, the imaging method comprising the steps of:
- imaging a subject under a predetermined imaging condition and outputting imaging data;
- generating the image data to be displayed on the display, from the imaging data;
- obtaining a distribution for each luminance from the image data, calculating an enhancement amount based on the expansion amount of gradation obtained in accordance with the percentage of high luminance, and controlling display-luminance in the display in accordance with the imaging condition and the enhancement amount;
- and
- controlling so as to image a subject with gradation on a high-luminance side expanded relative to a previously prepared gradation characteristic serving as a reference, generating the image data and storing the enhancement amount in association with the image data, and controlling display-luminance of the display, based on the expansion amount of gradation on a high-luminance side, in displaying the image data on the display.
A storage medium for storing a program code which executes an imaging method in an imaging device including a display capable of enhancing display-luminance of image data more than a predetermined reference luminance, the imaging method comprising the steps of:
- imaging a subject under a predetermined imaging condition and outputting imaging data;
- generating the image data to be displayed on the display, from the imaging data;
- obtaining a distribution for each luminance from the image data, calculating an enhancement amount based on the expansion amount of gradation obtained in accordance with the percentage of high luminance, and controlling display-luminance in the display in accordance with the imaging condition and the enhancement amount;
- and
- controlling so as to image a subject with gradation on a high-luminance side expanded relative to a previously prepared gradation characteristic serving as a reference, generating the image data and storing the enhancement amount in association with the image data, and controlling display-luminance of the display, based on the expansion amount of gradation on a high-luminance side, in displaying the image data on the display.
