Taking, for example, the case of extracting the image signal of a computer, conventionally, the image signal of various computers is used by using a cable or the like having different connectors at both ends. Due to
Since the connection between the image processing apparatuses and the like having different connectors was dealt with, the degree of freedom was low when changing or replacing the image processing apparatuses or the like. That is, when a new image processing device or the like is to be replaced or added, if the input / output connector of the device is a connector of another shape, it is necessary to newly prepare a cable suitable for the connector corresponding to the shape. was there. In addition, when a dedicated interface for electrical signals is adopted, the cost is high because the printed circuit board and circuit are designed and manufactured for each model, and when the model is changed, prompt measures are taken. It was difficult to do. An object of the present invention is to provide an image which, when connecting devices such as image processing devices having different connector shapes and electrical standards, can easily extract the signal and connect the devices to various connectors and electrical standards. An object is to provide an interface device for signal connection.
