DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, exemplary embodiments to which an interphone device of the invention is applied will be described with reference to the drawings. As shown in FIG. 1, the intercom apparatus of the present invention includes an entrance cordless handset 1 and a living room base phone 2. FIG. 2 shows an example of a screen diagram when the zoom operation is performed.

The entrance handset 1 includes a camera 101 that captures a visitor at the entrance, a handset sound unit 102 for talking with a resident, a call button 103 for calling the living room base unit 2, a living room base unit 2, It is comprised with the subunit | mobile_unit I / F104 for communicating.

The room master unit 2 includes a call button 207 for answering when called from the entrance slave unit 1, a master unit acoustic unit 205 for talking with a visitor, and a video signal sent from the entrance slave unit 1. , A human detection unit 203 for detecting a person in the captured image, a zoom button 206 for enlarging the captured image, and a zoom target person when the zoom button 206 is operated. A zoom screen determination unit 208 that determines the screen range that is included, a zoom processing unit 202 that displays the screen range determined by the zoom screen determination unit 208 on the monitor 201, and a recording unit that records the captured video 210, a CPU 204 that controls each part of the living room master device 2, and a master device I / F 209 for communicating with the entrance slave device 1. The person detection unit 203 includes a zoom person size determination unit 203a that determines a person to be zoomed, a zoom person distance determination unit 203b, and a zoom person front determination unit 203c.

The operation of such an intercom device will be described. First, the operation from the normal call operation to entering a call will be described.

When a visitor operates the call button 103 of the front door 1, a call signal is transmitted to the CPU 204 via the slave I / F 104 and the master I / F 209. The CPU 204 that has received the call signal controls the sound unit 205 to output a ring tone. Further, the audio signal from the sound 102 of the entrance unit 1 is output to the acoustic unit 205 of the living room base unit 2 via the slave unit I / F 104 and the master unit I / F 209, and the camera of the entrance unit 1. The video signal from 101 is output to the monitor 201 via the slave unit I / F 104, the master unit I / F 209, and the zoom processing unit 202. At this time, by operating the call button 207 of the home base unit, the audio signal from the acoustic unit 205 of the home base unit 2 is transmitted to the sound of the front handset 1 via the base unit I / F 209 and the slave unit I / F 104. The data can be output to the unit 102.

Next, the operation when the zoom operation is performed on the living room master unit 2 will be described.
When the image captured by the camera 101 is outputting the image as shown in FIG. 2A to the monitor 201, if the zoom button 206 is operated, the person detection unit 203 detects all the persons being imaged. Perform detection processing. Thereafter, the zoom screen determining unit 208 determines a screen range 301 including all detected persons, and the zoom processing unit 202 zooms so that the screen range 301 is displayed on the entire screen as shown in FIG. Process. At this time, it is preferable to set the screen range so that the enlargement magnification is as high as possible. Therefore, it is possible to confirm the video of only the person by a simple operation of the room master.

It is also possible to determine the status of a person imaged by the camera 101 and determine whether or not to be a person to be zoomed.

The zoom person size determination unit 203a determines a person whose person image is larger than a predetermined value among persons captured by the camera 101 as a zoom target person, and the zoom person distance determination unit 203b captures an image by the camera 101. The distance between the measured persons is measured, a person whose distance between the persons is within a predetermined value is determined as a person to be zoomed, and the zoom person front determination unit 203c includes the front of the persons captured by the camera 101. Can be determined as a person to be zoomed.

Accordingly, when the image captured by the camera 101 is output to the monitor 201 as shown in FIG. 2C when the image in which five persons are output is output to the monitor 201, the zoom person size determination unit is operated. The target person to be zoomed up can be determined by the distance determination unit 203b between the zoom persons 203b and the front person determination unit 203c of the zoom person (for example, the person at the center of the front is sideways and is not the target). Thereafter, the screen range 302 including the person determined as the person to be zoomed is determined by the zoom screen determining unit 208, and the zoom processing unit 202 displays the screen range 301 on the entire screen as shown in FIG. The zoom process is performed. By such an operation, it is possible to easily zoom up only the visitors.

In addition, since the entire video captured by the camera 101 or the zoomed video can be recorded by the recording unit 210, the zoom-in screen of the visitor can be confirmed later, and the vicinity of the entrance can be viewed. The suspicious person who is doing it can also be confirmed on the whole screen.

Furthermore, in the present embodiment, the person detecting unit 203, the zoom screen determining unit 208, the zoom processing unit 202, and the recording unit 210 are provided in the living room master unit 2, but may be provided in the front door unit 1.

As in the first to fifth embodiments, it is possible to zoom up only the visitors by a simple operation of the living room master, and it is possible to easily confirm the person.
