Abstract
A display control device for controlling displaying of images taken by a plurality of cameras each having a function of changing a zoom magnification includes: an operation unit including an operation element provided for each of the cameras to accept an operator's operation of setting the zoom magnification of the cameras, the operation unit being configured to output a input pulse signal corresponding to an operation amount of the operation element; and a W/T pulse convertor configured to convert the input pulse signal to a reference pulse signal that is uniformized variations in the zoom magnification of respective cameras with respect to a predetermined operation amount of the operation element, and output the second control signal to a corresponding camera.

A display control device for controlling displaying of images taken by a plurality of cameras each having a function of changing a zoom magnification, comprising:
- an operation unit including a plurality of operation elements, each of the operation elements provided for a corresponding camera to accept an operator's operation of setting the zoom magnification of the corresponding camera, the operation unit being configured to output a control amount of a first control signal corresponding to an operation amount of each of the operation elements;
- and
- a control amount convertor configured to convert the control amount of the first control signal to a control amount of a second control signal so as to uniformize variations in the zoom magnification of respective cameras with respect to a predetermined operation amount of each of the operation elements, and output the second control signal to a corresponding camera, the control amount convertor including a conversion table storage unit storing conversion data for converting the control amount of the first control signal to the control amount of the second control signal of each of the cameras.
A display control system, comprising:
- a plurality of cameras each having a function of changing a zoom magnification;
- and
- a display control device for controlling displaying of images taken by the cameras, wherein:
- each of the cameras comprises a zoom magnification changer;
- the display control device comprises:
- an operation unit including a plurality of operation elements, each of the operation elements provided for a corresponding camera to accept an operator's operation of setting the zoom magnification of the corresponding camera, the operation unit being configured to output a control amount of a first control signal corresponding to an operation amount of each of the operation elements;
- and
- a control amount convertor configured to convert the control amount of the first control signal to a control amount of a second control signal so as to uniformize variations in the zoom magnification of respective cameras with respect to a predetermined operation amount of each of the operation elements, and output the second control signal to the zoom magnification changer of a corresponding camera, the control amount convertor including a conversion table storage unit storing a conversion table configured to store a conversion coefficient for converting the control amount of the first control signal to the control amount of the second control signal of each of the cameras;
- and
- the zoom magnification changer is configured to change the zoom magnification corresponding to the control amount of the second control signal.
