Abstract

A still video apparatus is disclosed which has a device for interfacing with an external image data processing device. The still video apparatus comprises a signal output device for outputting an electrical image signal and a signal converter for converting the image signal to an image data signal which can be processed by the external image data processing device. The apparatus is provided with an interface which outputs the image data signal to the external image data processing device. The still video apparatus may be provided with a playback device and/or a recording device, whereby a signal converting device converts an image signal, which is read from a recording medium by the playback device, to an image data signal which can be processed by the external image data processing device. In the alternative, the still video apparatus may comprise a still video camera which has a camera body wherein the camera body has a device for converting an image of an object to be photographed to an electrical image signal, a recording device for recording the image signal onto a recording medium, and a playback device for reading the image signal recorded on the recording medium. The still video camera may also be provided with an adapter which can be detachably mounted to the camera body, and which comprises a converting device for converting the image signal read from the recording medium to an image data signal which can be processed by an external processing device, and an interface which outputs the image data signal to the external processing device.
