Abstract

PURPOSE:To prevent a user from feeling uncomfortable because a displayed video is switched suddenly by leaving the displayed video of a video display device as the video by a video apparatus as long as a selection instructing means is not operated even if a calling means is operated by a visitor, etc. CONSTITUTION:In the case the video information of the video apparatus is being displayed by the video display devices 37a, 37b at indoor parts 30A, 30B, when the calling means 34c at an entrance part 30C is operated, it is reported by reporting means 32A, 32B at the indoor parts 30A, 30B. At that time, at the video display devices 37a, 37b, the video corresponding to the video signal of the video apparatus is displayed without intermission, and when the selection of the video of a camera 35 is instructed by the selection instructing means 39a, 39b of the indoor parts 30A, 30B, the condition of the entrance is displayed first in response to the image pickup signal of the camera 35. Thus, in the case a user enjoys the video of the video apparatus, even if a call arises from the entrance, the video being displayed is never changed suddenly, and the user is prevented from feeling uncomfortable.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an intercom with a video display function that photographs an entrance hall using a camera and displays the photograph on an indoor video display device.

[Prior Art] An intercom with a video display function that projects images from a television camera installed at the entrance onto a video display device (display) in the kitchen or bathroom is disclosed in Japanese Patent Laid-Open No. 63-69.
There is an invention disclosed in Publication No. 89.

According to the present invention, the video display device can be used not only for simply showing the state of the entrance, but also as a video monitor for displaying video information from video equipment such as a video.

Therefore, if a visitor operates the calling member installed at the entrance while viewing video or other visual information, the image displayed on the video display device will be changed to the image captured by the television camera at the entrance. By forcibly switching, we ensure that no one goes unnoticed by the visitor.

[Problems to be Solved by the Invention] However, in the above invention, when a visitor operates the calling member while watching a video, etc., the displayed image on the image display device is always switched to an image captured by a television camera. Therefore, there is a problem in that the image being viewed, such as a video, is suddenly interrupted and the viewer feels uncomfortable.

The present invention provides an intercom with a video display function,
The video display device can be used as a video monitor for video equipment, and if there is a visitor while displaying video information from the video equipment, the presence of the visitor can be sensed and the discomfort felt at that time can be alleviated. The aim is to do as little as possible.

[Means for Solving the Problems] The present invention provides a communication device that connects an entrance section installed at an entrance and an indoor section installed indoors other than the entrance, wherein the entrance section includes a calling means. In the intercom with a video display function, a video device is installed, and a video device is installed in the room, and a video device is installed inside the room, and a video display device for displaying the video of the camera is installed. A signal selection means for selecting a video signal to be transmitted and a photographing signal of the camera, and a selection instruction means acting on the signal selection means to instruct a selection between the photographing signal and the video signal are provided in the indoor space. technical means.

[Function] In the present invention, when the video information of the video equipment is displayed on the video display device indoors, when the calling means in the entrance is operated, the notification means makes a notification indoors.

At this time, the video display device continuously displays the video according to the video signal of the video equipment, and only when the selection instruction means inside the room instructs the selection of the camera video, the video display device displays the video of the entrance according to the photographing signal of the camera. The situation will be displayed.

[Effects of the Invention] In the present invention, when the calling means is operated by a visitor or the like, the notifying means issues a notification, so the presence of the visitor can be sensed.

At this time, even if the calling means is operated by a visitor or the like, the displayed image of the video display device remains the image of the video equipment unless the selection instruction means is operated, and the displayed image will not be switched unexpectedly.

Therefore, while enjoying a video or the like, the user will not lose interest in the video information being displayed and feel uncomfortable.

[Example] Next, the present invention will be explained based on examples.
