Abstract

PROBLEM TO BE SOLVED: To move a camera part and to display an object which is a target in the central part of an image by touching the object shown at an edge of the image with a finger by adopting a touch panel type display and a video signal detection circuit. SOLUTION: When an object image 10 is touched with a finger, the coordinate axes of the object on a display are detected and supplied as positional information to a processing circuit. The detection method for position coordinates on a touch panel is widely known and detects coordinates on an X-axis and a Y-axis by blocking a sensor (optical sensor) with the finger on a touch panel plane. The processing circuit transmits control data, so as to move the object in the direction of the center on a screen in response to positional information sent from a touch panel display 5, and a controller supplies a control drive signal to a zoom lens and an electrically-driven pan head. Thus, the zoom lens and the pan head are made to move so that the target object 10 is located at the central part of the screen.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to the operation of surveillance television camera systems.

[0002]

2. Description of the Related Art Surveillance systems using television cameras have been widely used. FIG. 4 is a block diagram showing the basic configuration of the image forming apparatus. Reference numeral 1 denotes an image synthesizing switch for switching or synthesizing an image from a television camera and an image from a personal computer and outputting them. 2 is a TV camera, 3 is a remotely controllable zoom lens, 4 is a remotely controllable electric pan, 5 is a monitor, 7 is a pan and zoom lens controller, 8
Is a personal computer.

A conventional technique will be described with reference to FIG. In the surveillance television camera system, when the subject projected on the screen of the monitor 5 is to be monitored in detail, the operating device screen 51 shown in FIG.
The control signal is supplied to the zoom lens 3 and the electric pan / tilt head 4 attached to the television camera 2 to display the subject on the center and enlarged on the screen. On screen 51, 52
Is a button for performing zoom lens control, 53 for focus control, 54 for tilt control, and 55 for pan control. The operation at this time is manually performed by a human selecting and clicking with a mouse while monitoring the monitor screen, or manually using a touch panel.

[0004]

In the method of operating the operating device manually while monitoring the monitor screen, the camera must keep operating until the target object moves to the center of the screen. However, the burden on the operator is large.

[0005] For example, in the prior art, in order to move up a target object by moving a zoom lens or an electric pan head, a touch panel is monitored by touching a switch on the screen while monitoring a monitor screen. I have to continue. This means that you must keep your finger on the screen while the lens or head is activated. Since this time takes about 10 seconds at the maximum, when the operation is frequently performed, the operation is complicated.

[0006]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems by using a touch panel display as an image monitor and touching a projected target object with a finger. The above position is detected, and a control signal for moving the camera unit to a position where detailed monitoring can be performed is provided.

[0007]

FIG. 1 shows an example of a display screen on a monitor showing an embodiment of the present invention. Reference numeral 10 denotes a subject.

FIG. 2 is a diagram showing the block configuration.
In this figure, reference numeral 9 denotes a processing circuit, and the same reference numerals as those in the other figures denote the same parts. When the arithmetic control in the processing circuit 9 is performed on software of a personal computer, the overall hardware block configuration is basically common to the conventional one. First, the overall operation will be described.

An image from the television camera 2 is displayed on the touch panel display 5 as an image. The television camera 2 is provided with a zoom lens 3 and an electric pan head 4 as an accessory. When a target object 10 shown in FIG. 1A is touched with a finger in the image displayed on the touch panel display 5, the coordinate axis of the object on the display is detected and supplied to the processing circuit 9 as position information. The detection of the position coordinates on the touch panel is a well-known method of detecting coordinates on the X axis and the Y axis by blocking a sensor (optical sensor) on the touch panel surface with a finger. The processing circuit 9 sends control data based on the position information sent from the touch panel display 5 to move the subject toward the center on the screen, and the controller 7 controls the zoom lens 3 and the electric pan head 4.
To supply a control drive signal. As a result, the zoom lens 3 and the electric camera platform 4 move so that the target object 10 is located at the center of the screen.

Next, the processing circuit 9 captures the video signal of the camera 2 and detects a target subject on the video signal.
At the position where the target subject moves to the center on the video signal and the size of the subject on the screen becomes half the screen height, the supply of the control signal to the zoom lens 3 and the electric pan head 4 is stopped. Let it. FIG. 1B shows an image obtained as a result. Thus, the subject located at the end in the screen can be enlarged and displayed at the center by a simple operation.

This operation will be described in further detail. When the position of the monitoring target on the touch panel is determined by a finger, the processing circuit 9
In, the position is marked on the video signal as shown in FIG. Then, the position of the marking and the moving time to the center of the screen are calculated from the moving speed of the electric head in both the horizontal and vertical directions. FIG. 3 is a diagram showing a relationship between a video signal and a screen.

At this time, the focal length of the lens is fixed.

[0013] Then, in order to move toward the center of the screen,
The control signal is supplied to the electric pan head for the calculated travel time via the controller.

In this state, the subject moves to near the center of the screen.

[0015]

According to the present invention, the operational burden on the surveillance television is greatly reduced.
