Embodiment Construction

[0027] Next, an example of application to a digital camera as an embodiment of the present invention will be described. This digital camera has an imaging circuit, converts the subject image into image data by the imaging circuit, and performs live view display of the subject image on a display unit such as a rear display arranged on the back of the main body based on the converted image data. . Photographers determine composition and shutter opportunities by looking at the live view display. When the release operation is performed, image data is recorded in the recording medium. When the reproduction mode is selected, the image data recorded on the recording medium can be reproduced and displayed on a display unit such as a rear display.

[0028] FIG. 1 is a block diagram showing the main electrical configuration of a camera according to an embodiment of the present invention.

[0029] The photographic lens 101 is composed of a plurality of optical lenses (including a focu...

Abstract

The present invention gives a sense of glare to a display image an displays a high sense of presence by producing a sufficient gradation expression from high light to highest light. An image-capturing device having a display means with which it is possible to make the display luminance of image data enhanced over prescribed standard luminance, wherein the image-capturing device has an image-capturing step (S1) for capturing the image of a subject under a prescribed photographing condition and outputting image-capture data, an image-processing step (S3) for generating image data for display on the display means from the image-capture data, and control steps (S7-S25) for controlling the photographing condition in the image-capturing step and the enhancement of display luminance in the display means. The control steps control the image-capturing step so that, as an image is captured, gradation on the high luminance side is extended against a gradation characteristic that servers as standard (S13), and control, when displaying the image data on the display means, the enhancement of the display luminance of the display means on the basis of the extended amount of gradation on the high luminance side in the image-capturing step (S15).

Description

technical field [0001] The present invention relates to an imaging device, an imaging method, and an image display device capable of reproducing a high-brightness portion of an object with a high sense of presence. Background technique [0002] In the case of live view observation through the display unit, the live view image appears from shadows to highlights in the brightness range of the display panel. Therefore, it is impossible to display a brightness exceeding the highest brightness (called "highest light"), so that the dazzling feeling as seen by the naked eye cannot be displayed. In addition, the dynamic range is expanded by compositing images captured with varying exposure times, thereby enabling the expression of gradations from bright to super bright. [0003] However, in this method, it is only a representation within the luminance range of the display panel. Patent Document 1 discloses a technique of detecting a glossy portion of an image, and increasing the l...
