Abstract

PURPOSE:To dispense with a letter title production circuit by making it possible to photographing the transparent substance placed at the hole through of a lens cover on which the letter title is written. CONSTITUTION:Transparent recording paper 8 on which pictures including titles to be photographed is rolled on one side of bobbin 3b and the edge of the paper is inserted into the slit of the other bobbin 3a and they are attached to lens cover 1 in this situation. And then the lens cover is attached to the front of lens system of camera body. And the letter titles written on the recording paper are photographed and recorded on VTR by setting the zoom lens at macro-range. The recording paper can be advanced to the next frame only by rotating rollet 5. When this device is used as a cover of lens, open/close door 6 is rotated around a hinge 7, and protrusion part 9 is mated with mating part 10 of the cover body 1, and fixed onto it.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a video camera device that can be used to edit text titles when taking pictures with a video camera.

BACKGROUND ART When editing a video work recorded using a video camera and a VTR, it is necessary to insert text titles at the beginning and end of the work.

For this reason, conventionally, as shown in FIG.
A keyboard 11 was installed in the computer, and the title was typed in while selecting characters using the keyboard 11.

Problems to be Solved by the Invention However, in such a device, a complicated circuit is required to create a character title, and therefore a large number of parts such as two integrated circuit elements are used, making the video camera expensive. , I was also having trouble editing the title.

The video camera device of the present invention eliminates these conventional drawbacks, and provides a simple video camera device that has a simple configuration and does not require camera operation for title creation.

Means for Solving the Problems The video camera device of the present invention is provided with a through hole in the lid body which is removably engaged with the tip of the lens barrel of the video camera body, and a transparent hole on which the image to be recorded is drawn. Means is provided for detachably holding the body on the lid so as to cover the through hole.

Function: The video camera device of the present invention utilizes the macro focus function of the camera lens to photograph a transparent object on which a text title or the like is drawn, which is placed in a through hole provided in the lens lid. This method has the advantage of eliminating the need for a character title creation circuit, which was previously required, and simplifying operations.

Embodiments Hereinafter, video camera apparatuses according to embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of a video camera device showing an embodiment of the present invention, in which 1 is a lens lid body detachably engaged with the tip of a lens barrel of a camera body; 2 is a lens lid body 1; A through hole 3a provided in the center.

3b is a bobbin having a slit 4, and knurls 6 are provided at both ends of the bobbin, which are rotatably disposed on both sides of the through hole 2, respectively. Reference numeral 6 denotes an opening/closing door rotatably provided on the lens lid body 1 by a hinge 7, and is configured to cover the through hole 2 when closed. When using this device, a band-shaped transparent recording paper 8 on which an image such as a title to be recorded is drawn is placed on one bobbin 3.
bobbin 3a and its end through the slit 4 of the other bobbin 3a.
Insert and engage the lens cover 1 into the lens cover 1 as shown in Figures 1 and 3, then attach the lens cover 1 to the lens barrel of the camera body, and then attach the zoom ring of the camera to the macro When you set it on the range and take a picture, the text title written on the recording paper is recorded on the VTRK.

When you want to advance the recording paper to the next page, use knurling 6.
You can advance to a new character title by simply moving frame by frame. If you want to leave this device unused and use it as a lens cover, rotate the opening/closing door 6 around the hinge 7 as shown in Figure 4, and attach it to the opening/closing door 6 as shown in Figure 3. The fitted protrusion 9 is inserted into the fitting part 1o of the lens lid body 1.
It can be fixed by fitting and fixing it.

In the above embodiment, a configuration was shown in which a band-shaped recording paper was used and the recording paper was sequentially wound onto a bobbin. However, the recording paper configured in the form of a slide film was held one by one in the through-hole of the lens lid body. It is also possible to have a configuration in which

Effects of the Invention As described above, the video camera device of the present invention has a through hole in the lens cover of the video camera, and a means for holding a transparent marking paper in front of the through hole, thereby improving the macro focus function of the camera. By taking a picture of the text title on a transparent recording paper using a camera, there is no need for a complicated circuit for title creation or camera operation, and it is now possible to use only English text titles. Japanese titles, various illustrations, etc. can be used freely, which will also lead to lower prices and smaller cameras.
