CONSTITUTION:A photographic image of a photographic print 2, etc., arranged on an X-Y table in order to obtain each split image displayed on a multi-image display device is brought to an image pickup by a color television camera 8 and displayed on a monitor television 14, and also, a trimming frame 30 corresponding to each split image is superimposed and displayed on the monitoring television 14, and an image in a region shown by this trimming frame 30 is brought to an image pickup successively by a prescribed image pickup magnification. In such a way, each split image shown by the trimming frame 30 on the monitoring television 14 coincides with each split screen for constituting a multi-screen, therefore, the trimming of a multi-image displayed on the multi-screen can be executed, while monitoring the image displayed on the tube surface 14 of the monitoring television 14.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a still image trimming device for trimming still images such as photographic prints, and in particular, to a still image trimming device for trimming still images such as photographic prints, and particularly to a still image trimming device in which a trimming frame for setting a trimming area on the still image is superimposed. The present invention relates to a still image trimming device capable of trimming a still image while monitoring a synthesized image.

[Conventional technology]

Recently, with the arrival of the new media era, various Δ■(
(audio/visual) products have been developed and put into practical use. Among these AV products, video signal regenerators such as magnetic recording and reproducing devices that reproduce still images recorded on rotating magnetic recording media on display screens such as televisions are attracting attention because they can easily display images in a sliding manner. is bathed in

An image display device configured by combining a television and such a video signal regenerator is characterized in that it stimulates the viewer's vision to a particularly high degree. Therefore, a large number of image display devices having such characteristics are installed on streets, exhibition halls, etc. for the purpose of transmitting various kinds of guide information or functioning as a medium for advertisements and promotions.

Conventionally, when recording a still image such as a photo print, which is one type of still image, on such a video signal regenerator, the photo print is imaged, and a video signal corresponding to the still image obtained by this image capture is generated. I am trying to record it on a recording medium.

For example, as a device for creating a video signal corresponding to such a still image, there is a film video blurr disclosed in Japanese Patent Publication No. 59-501768. This film video player focuses a still image of a film disk on the light receiving surface of a solid state color image sensor on an X-Y translation stage through an optical system with variable imaging magnification. Outputs an electrical signal corresponding to the image. The film disk player uses a signal processing electronic circuit to create a video signal based on this electrical signal. Further, the video signal created in this way is supplied to a television, and a still image based on the video signal is displayed.

On the other hand, the applicant of the present invention has proposed a multi-screen display device for the purpose of providing image information to many people at once in a place where many people gather. In this method, the display screens of a plurality of display devices are arranged in a plane to form one multi-screen as a whole, and each partial image of one still image is simultaneously displayed on the display screen. As a result, the one still image is displayed on a multi-screen formed by the plurality of display screens. Each of the plurality of display devices constituting such a multi-screen display device is provided with a video signal regenerator that displays each divided image in one-to-one correspondence.

[Problem that the invention seeks to solve]

In the film video blurring device, when a portion of a still image on a film disc or the like is trimmed to create a video signal, the entire still image displayed on the display device must be constantly monitored and trimmed. , Once cropping is performed, the entire still image cannot be displayed. Therefore, it requires skill to align the optical axis of the optical system with the center of a portion of the still image on the film disc by visual measurement and to adjust the imaging magnification of the optical system to a predetermined value, and the work is time-consuming. In addition, when creating video signals corresponding to each divided image necessary to trim a still image and display it on a multi-screen, the main part of the still image (for example, the face of a person) is displayed on the multi-screen. It is necessary to avoid unnatural multi-image display by matching the wooden frame that supports each display device of the display device and the non-display portion of the peripheral portion of each display screen where overscanning is performed. However, the still images displayed on the television,
While monitoring, it is difficult to take into account the wide frame corresponding to the non-display area, and manually align the optical axis of the imaging optical system with the center of the divided images on the film disk to take an image.

The present invention has been made in view of the above circumstances, so that when a still image on a film disc or the like is trimmed to create a video signal, the periphery of the trimmed portion of the still image is added to the still image displayed on a television or the like. It is an object of the present invention to provide a still image trimming device which can be trimmed while setting and is configured to automatically create a video signal corresponding to a still image set by a periphery.

[Means for solving problems]

In order to achieve the above object, the present invention provides a still image trimming device that captures still images such as photographic prints and trims them while displaying them on a cathode ray tube or the like, which includes a support base on which the photographic prints are placed, and an imaging magnification. an imaging means having a variable optical system and outputting a video signal obtained by imaging a photographic print or the like placed on the support base; a driving means for moving the support base or the imaging means; and a drive means for moving the support base or the imaging means; a pattern generation means for outputting a pattern signal of a trimming frame for setting a trimming edge for printing, etc.; and a pattern generation means for outputting a pattern signal of a trimming frame for setting a trimming edge for printing, etc.; a signal processing means for outputting a video signal corresponding to the imposed composite image; an image display means for displaying the composite image based on the video signal from the signal processing means; The driving means is controlled so that the optical axis of the optical system of the imaging means coincides with the center of the corresponding still image, and the still image corresponding to the image area indicated by the trimming frame is displayed on the image display means. It is characterized by comprising a control means for controlling the imaging magnification of the optical system to be increased so that the image is displayed on the entire screen.

[Effect]

In the present invention, a still image such as a photographic print placed on a support stand is imaged by an imaging means having an optical system with variable imaging magnification. Next, the video signal obtained by this imaging,
A pattern signal corresponding to the trimming frame outputted from the pattern generating means is synthesized by the signal processing means. As a result, a video signal corresponding to a composite image in which a trimming frame is superimposed on a still image is output, and this video signal is supplied to the image display means. The control means adjusts the imaging magnification of the imaging optical system so that the photographic image within the image area indicated by the trimming frame in the composite image is enlarged and displayed on the composite image displayed on the image display means, and The driving means is controlled so that the still image is moved and displayed on the display screen. In this way, the trimming area of the still image is set by the trimming frame, and a video signal corresponding to the still image of the image area set by the trimming frame is automatically created.
