Problems solved by technology

[0007] However, in this prior art, since the ultraviolet intensity is compared with the light intensity of the other three bands, the technique is somewhat complicated, and a quick response cannot be obtained.
In addition, when the ambient lighting of the camera is different from the lighting of the subject, when trying to take pictures from indoors to outdoors, some ultraviolet rays are absorbed by the window glass, so there is a problem that the white balance cannot be adjusted.

[0042] figure 1 Shown is a first embodiment of the present invention in which the ultraviolet receiving element is disposed on the opposite side of the lens of the digital camera. In the ultraviolet receiving element 10 for receiving and detecting ultraviolet rays including UVA, a lens that transmits ultraviolet rays and converges ultraviolet rays may be provided for converging ultraviolet rays including UVA onto the light receiving surface.

[0043] The ultraviolet receiving element 10 is provided on the surface of the digital camera 12 opposite to the surface of the camera on which the photographic lens 14 is provided. In the digital camera 12, a microcomputer for judging a subject shooting condition by a subject shooting condition judging program, and a white balance adjustment device for adjusting the white balance according to the set white balance adjustment are provided.

[0044] In this embodiment, by the microcomputer mounted on the digital camera 12, according to ...

[0052] In the second embodiment, as image 3 As shown in , ultraviolet receiving elements 10A and 10B are provided on both sides, that is, on the lens-side surface of the camera and on the opposite side of the lens-side surface, and by comparing the outputs of the two ultraviolet receiving elements, it can be determined whether the camera faces The sun, that is, whether the sun is on the back side of the object. Note that the ultraviolet receiving elements 10A and 10B respectively have the same configuration as the above-described ultraviolet receiving element 10 .

[0053] Also, by setting the threshold value (set value B) of the output difference (or output ratio) in advance, it is possible to determine whether the shooting condition is a completely backlit state, or whether the shooting condition is such a state that although the sun is behind, it is slightly It's a bit cloudy, and the light has relatively little effect on the brightness of the background and the brightnes...

Abstract

This invention relates to a device for judging the camera conditions of an object of an image pick up device including an ultraviolet ray test unit for testing the received ultraviolet rays, a comparison device for comparing the ultraviolet strength tested by the test unit with that preset and a deciding device for deciding the pick-up condition of the object based on the comparison result of thecomparing device.

Description

technical field [0001] The present invention relates to a subject shooting condition judging device, an image quality adjusting device, and an image taking device, and more particularly, to subject shooting in which a subject shooting condition (such as a light source type) is judged by an ultraviolet receiving element (ie, an ultraviolet detecting element) as an external sensor. Condition judging means, image quality adjusting means for adjusting image quality according to determined subject shooting conditions in image capturing apparatuses such as digital still cameras and video cameras, and image capturing apparatus including the subject shooting condition judging means and the image quality adjusting means. Background technique [0002] Digital cameras and mobile phones with digital cameras have been widely popularized recently. These digital cameras, unlike silver-halide film cameras, generally shoot images of the subject while referring to the image of the subject in ...
