Abstract: A network camera, a program and a network system, which can perform voice communications by comfortable operations. The network camera can transmit an image to at least one terminal capable of performing a voice communication in a half duplex manner, and can perform a voice communication with the terminal. The network camera creates and transmits page information to the terminal. This page information displays: a button indicating the possibility of outputting the voice when it receives a demand from the terminal, in case the voice output is not inhibited and in case another terminal is not outputting the voice; a button indicating the voice outputting, in case the voice output is done; and a button indicating a temporary voice output inhibit while another terminal is transmitting the voice, so that the page information can be altered, when depressed, to another button display in accordance with the change in the communication state.

Abstract: An image server and an image communication system capable of displaying images of plural image servers differing in IP address on a browser window by using a versatile browser, and a methods for controlling them. Plural image servers communicate with a client computer displaying image information presented from image servers through a network. Of the plural image servers, the controller of a certain image server receives a request from the client computer, and displays the image data of the image server and image data of other plural image servers simultaneously on the browser window of the client computer. Accordingly, the controller of the designated image server creates display information, and supplies the information to the client computer.

Abstract: The invention aims at providing server apparatus capable of outputting image data and sound data thereby deactivating sound transmission at a low cost and with ease. That is, a sound input device (microphone) for converting sound to a sound signal is made detachable. A connection detector for detecting whether this sound input device (microphone) is connected is provided. In case the sound input device is connected to a sound input section, the sound transmission function is automatically controlled into the operating state. In case the sound input device is not connected, the sound transmission function is automatically controlled into the non-operating state. Thus, only a simple procedure of removing the sound input device from the sound input section is needed to deactivate sound transmission. This allows switching between activation and deactivation of sound transmission at a low cost.

Abstract: The invention allows the user to operate the camera of an image server via a network and acquire via voice the information associated with the imaging position of the camera.

Abstract: The present invention provides a network camera system in which, when images are window-displayed, the images and audios can be outputted in association without requiring any special operation. The network camera system comprises one or more network cameras (2, 2a, 2b, 2c), each of which includes an applet/plugin transmission unit which transmits an applet for reproducing an image displaying window and a audio in association in a network terminal (1). The network terminal (1) window-displays an image accompanying the audio, contained in a received Web page, and it downloads the applet or the like from the camera. The applet or the like performs a control so as to emit the audio of the network camera corresponding to the window which a user has designated in the network terminal (1) by, for example, moving a cursor to this window and clicking it.
