Abstract

Provided is a liquid crystal screen direct view finder device which prevents direct sunlight and other miscellaneous light from being reflected on a liquid crystal monitor during photographing with a digital camera and which has a finder function in the liquid crystal monitor.
A dark box 1 is provided that can cover and cover the periphery of a monitor screen 9 of a digital camera 8 to block direct sunlight and other light from the surroundings. In addition, a viewing hole is provided in the central portion of the dark box so that the monitor screen can be seen, and an eyepiece 6 is attached so that the liquid crystal screen can be clearly seen at a close distance.

Description

  The present invention relates to a direct view finder device in which a dark box with an eyepiece attached to a liquid crystal monitor of a digital camera.

Digital cameras are widely used because they have a simple structure and are easy to handle, but there are very few models equipped with an eyepiece finder that captures captured images. Therefore, in many cases, shooting is performed while staring at the image projected on the LCD monitor. In particular, when shooting outdoors, direct sunlight or bright ambient light is often radiated, making the monitor screen unclear and often hindering good shooting.
Also, when shooting images on the LCD monitor as a viewfinder, the physiological focal length of the human eye is about 30 centimeters, so when focusing most importantly on shooting, a detailed image with the eyes close to the monitor In general, it is difficult to check the screen, and it is necessary to check the focus and the screen configuration with a distance of about 30 cm from the small monitor image, resulting in poor accuracy.

New models of digital cameras are on the market one after another, but there are few eyepiece-type viewfinders for compactness or compactness. In addition, when using a camera with an interchangeable lens or a zoom lens, a finder with a linking function is not found because the linking mechanism with the finder is complicated and expensive, resulting in problems in versatility.
In addition, as a countermeasure against extraneous light such as direct sunlight, the photographer is currently struggling to make shadows in an unstable state with one hand or clothes depending on the situation.

  The present invention is a method for simultaneously solving the above-mentioned finder function and the problem of direct sunlight and irradiating light from the surroundings on the LCD monitor screen, in order to block the light around the monitor screen and cover it closely. If a dark box is provided and a peephole is opened in the center, that is, at the bottom, it is possible to view the monitor screen while blocking direct sunlight and ambient light. Furthermore, in order to see the monitor screen more clearly as a viewfinder, it is possible to see the LCD monitor screen close and in detail by attaching an eyepiece to the peephole at the bottom of the dark box, and it has a function as an eyepiece-type viewfinder It will be a thing. Since the digital camera can be viewed directly on the monitor screen without using the dark box in view of its application, the above-mentioned dark box is preferably a detachable type that can be mounted.

As described above, this model is a small digital camera that can be photographed as a removable eyepiece finder that can be attached to the camera by installing a dark box that can be photographed without being obstructed by direct sunlight and ambient light. When necessary, it can be installed and used. By separating from the camera body, it is compact and lightweight and easy to carry.
On the other hand, the function as a viewfinder differs from the conventional optical viewfinder in the following points. In other words, the optical system looks at the subject before photographing through the lens except for a special camera, whereas the finder of the present plan assumes that the subject is captured by the camera, performs image processing, and assumes a state after photographing. For example, there is a feature that the number of shooting failures is reduced, for example, by focusing on a dark subject even when a bright subject is viewed.

It is a top view which shows the Example of the liquid crystal screen direct view finder apparatus of this invention. It is a side view of this finder apparatus It is sectional drawing of a-a 'in FIG. 1 of this finder apparatus.

The dark box, which is the most central in implementing this plan, can be implemented by sheet metal bonding, sheet metal pressing, plastic molding, or the like. However, since the dark box comes into contact with the periphery of the liquid crystal monitor surface of the camera, plastic having a softer taste than hard metal is preferable, and plastic molding that can be integrally molded including the holding portion is desirable. In addition, the depth of the dark box can be shortened as the viewing angle is increased in a single lens unit or in a group configuration. The lens is placed in the holding lens barrel, and the focus adjustment screw is cut off in part of the lens barrel and engaged with the screw provided inside the lens barrel holder at the center of the dark box. Used for adjustment.
The camera can be attached to the tripod screw hole on the bottom of the camera with a tightening screw provided in the holding part.

Hereinafter, an embodiment will be described with reference to the accompanying drawings. Reference numeral 1 denotes a plastic molded dark box. Reference numeral 2 denotes a lens holding lens barrel. Reference numeral 3 denotes a lens barrel holding portion protruding in the center of the dark box. The inner and outer periphery of the lens barrel are threaded to engage with each other, and the position of the lens barrel can be finely adjusted to the left and right in the figure. Reference numeral 4 denotes a holding unit which holds the dark box on the camera body with a tightening screw shown in 5, and may be integrally formed with the dark box or manufactured by sheet metal or the like.
Reference numeral 6 denotes a lens mounted in the lens barrel. Reference numeral 7 denotes a screw portion for finely adjusting the position of the lens barrel.
8 is assumed to be a digital camera when the present plan is used, and is shown by a broken line for reference. Reference numeral 9 conceptually shows a liquid crystal monitor section of the camera.

  This plan already has a digital camera, and the main objective is to obtain a good shooting environment by blocking direct light and other miscellaneous light when using this camera. It can be easily considered. For example, it is considered that the photographing environment can be further improved by folding the dark box and using a lens having a plastic thickness as thin as possible.
