Embodiment Construction

[0041] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, in which a video camera device and a monitor are connected by a cable.

[0042] FIG. 1 shows a state when an HD video camera device 10 is connected to an HD monitor device 20 by a cable connection device 30 . In this case, the HD video camera device 10 shoots video with high definition, and the HD monitor device 20 displays the high-definition video signal (hereinafter simply referred to as an HD video signal). Also, the cable connection device 30 is used to transmit HD video signals. FIG. 1 also shows a state when the SD video camera device 40 is connected to the SD monitor device 50 by the cable connection device 60 . In this case, the SD video camera device 40 shoots a video with standard definition, and the SD monitor device displays a standard definition video signal (hereinafter simply referred to as an SD video signal). Furthermor...

Abstract

A video device comprises: a video signal processor generating a standard definition video signal at least having a composite signal and a high definition component video signal; an outputting unit outputting the standard definition video signal or the high definition component video signal to a cable to be connected; a discriminating unit discriminating a kind of cable connected to the outputting unit; and a switch allowing the outputting unit to selectively output the standard definition video signal and the high definition component video signal on the basis of the discrimination result of the discriminating unit. When the discriminating unit determines that the cable connected to the outputting unit is a cable for a high definition signal, the switch allows the outputting unit to output the high definition component video signal.

Description

technical field [0001] The present invention relates to a video device (such as a video camera) capable of discriminating the type of cable connected to an output device, an output switching method for the video device, and a cable discriminating method. Background technique [0002] Examples of video camera devices such as video devices include HD video camera devices that can capture high-definition pictures and SD video camera devices that can capture standard-definition pictures. [0003] The HD video camera device is provided with an output unit so that a captured picture is output to a monitor such as a television receiver. Specifically, an HD video camera device is provided with an A / V output terminal and a component output terminal that output a standard definition video signal (SD video signal) and an audio signal with a right channel R and a left channel L, and the component output terminal outputs a high-definition component video composed of a brightness signal ...
