JPH077267U - Camera with viewfinder - Google Patents

Abstract

(57) [Summary] [Purpose] Display in the viewfinder that the subject is captured by the camera. [Configuration] The receiving device is assembled by aligning the directivity axis substantially parallel to the lens axis of the camera, and is configured to display the reception in the viewfinder.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a camera having a viewfinder that makes it easy to identify a specific subject that is difficult to distinguish from other subjects only by looking at the viewfinder.

[0002]

[Prior art]

 The black-and-white viewfinder that uses a small CRT of about 0.6 inch, which is installed in video cameras that are popular nowadays, does not have colors and the screen is small. It can be difficult to find. For example, at a children's sports day, it is difficult to find the desired child in the viewfinder from among many of the same dressed children.

In recent years, a color viewfinder using a liquid crystal has been mounted, but in reality, it is inferior to a viewfinder using a CRT in terms of resolution and brightness. Therefore, there is no big improvement for the problem of shooting like the above example.

As a solution, it is possible to use a large monitor of several inches, but it is practical because it is large in size for general outdoor use and a large-capacity power source is required. is not.

[Problems to be solved by the device]

The problem to be solved is whether or not it is possible to easily find the target object from the objects that are difficult to discern from the appearance while looking through the viewfinder. .

An object of the present invention is to solve the above-mentioned problems and eliminate the conventional defects. In other words, the aim is to provide a camera that makes it possible to easily find the target subject among the subjects that are difficult to distinguish from the outside while looking through the viewfinder.

[0007]

[Means for Solving the Problems]

 In the present invention, a transmitting device (light emitting device, radio wave transmitting device, etc.) is attached to a target object in advance, and a receiving device (light receiving device, antenna, etc.) having directivity in the same direction as the camera lens attached to the camera is provided. , The fact that the transmission signal from the target subject is received is displayed in the viewfinder to let the photographer know that the camera lens is facing the target subject.

【Example】

 2 and 3 are examples of transmitting devices attached to the subject of the camera of the present invention. FIG. 2 is a perspective view of the transmitting device 1 attached to a hat 2, and FIG. 3 is a perspective view of a badge-like transmitting device. Is. In FIG. 2, the transmitting device 1 includes a light emitting element, an electronic circuit, and a battery, and emits modulated infrared rays to the surroundings. The badge shown in FIG. 3 emits a modulated radio wave, which is composed of an antenna, an electronic circuit, and a battery, and has a clip or an adhesive tape for attachment on the back surface of the badge.

FIG. 1 is a perspective view of a video camera to which the receiving device 5 is attached. It is assembled to be parallel to the directional axis of the receiving device 5 and the axis of the camera lens. FIG. 4 is a sectional view of the receiving device 5. A light-receiving element or an antenna 7 is mounted in the cylinder 6 to provide directivity. FIG. 5 is a front view showing that the reception is displayed in the viewfinder. An LED 9 is attached to the outside of the CRT surface 8 to display the reception. As another example, it may be displayed as an indicator in the image of the viewfinder.

[Effect of device]

 As described above, according to the present invention, even when photographing a subject that is difficult to distinguish from others, it is possible to start the photographing just by panning the camera and confirming the position of the target subject. Although a video camera has been described in the embodiment, it is obvious that a camera having a viewfinder can be used.
