Then, the photograph with a display can be quickly and easily taken.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographer with a display suitable for taking a photograph with a display such as a construction completion report photograph and a photograph containing necessary information such as a date.

[0002]

2. Description of the Related Art To explain using a photo for construction completion report as an example, in public works and other various constructions, when construction is completed, a photo with a display of the construction site along with a signboard showing necessary items, Must be attached to the completion report. Then, a blackboard was used as a signboard for displaying necessary items, the signboard was leaned against a construction site, and the signboard and the construction site were photographed on the same screen. It should be noted that after recording the necessary items with chalk on the blackboard and taking a picture, the written necessary items are erased and new necessary items are written, so that it is used repeatedly.

[0003]

[Problems to be Solved by the Invention]
If the subject is, for example, a construction site in a distant place and a signboard installed in a close place, both must be clearly projected on the same screen, and the photometric values at a distant place and a close place are Because it greatly depends on the influence of diffuse reflection,
When you use auto exposure to measure a distant subject and shoot,
The sign on the shooting screen appears dark and the characters on the sign are difficult to read. In addition, when photographing the upper part of the telephone pole, there is always backlight, and the characters of the photographed signboard are hardly discernable.

When taking a picture, the signboard is leaned against the construction site, and the construction site and the signboard are displayed on the same screen. Therefore, when taking pictures from different directions, the signboard must be turned upright in the direction of the camera each time. However, it takes time and effort. In the case of high-altitude work such as construction on a telephone pole, the installation place of the signboard is limited. In addition, on the blackboard, the letters written at the beginning of use are clear, but since letters are written and erased, the letters become white and the contrast decreases as the number of times of use increases. It becomes unclear and difficult to read.

In order to solve the above-mentioned inconvenience, the inventor of the present invention attaches a camera using a short focus lens to one end of the arm and a signage paper holder attached to the other end of the arm. Was prototyped. However,
When taking a photograph with a display by using a prototype photography tool with a display, the focus was not focused unless the aperture value was set to F22 or less. If the aperture value is set to F22 or less, the exposure time becomes long and the shutter becomes slow, so use a tripod to prevent camera shake, or use ASA / ISO 1600
I had to use a high speed film like 3200.

The present invention has been made in order to eliminate the above-mentioned inconvenience, and even if the photographing place is moved, it is possible to take a picture with a display quickly and easily without the trouble of resting the signboard. The present invention provides a photography tool with a display.

[0007]
