first embodiment

[0041]FIG. 1 schematically shows an entire configuration of a network camera system according to the invention. The network camera system 1 includes a digital camera 110, an adapter device 200, an ADSL modem 301 and a client PC 400.

[0042]The digital camera 110 is capable of capturing a high-resolution digital still image, a maximum size of which is 3200×2400 (pixels). Further, the digital camera 110 has a video output function, and is capable of outputting a video signal output by the CCD of the digital camera 110 as an NTSC signal. The digital camera 110 also has a USB (Universal Serial Bus) interface as a communication interface to communicate with an external device.

[0043]The digital camera 110 is connected with the adapter device 200 through a USB (Universal Serial Bus) cable 102 and a video cable 103. The adapter device 200 receives the NTSC signal representing an moving image through the video cable 103, and the high-resolution digital still image through the USB cable 102, fr...

second embodiment

[0123]In the above-described embodiment, the digital camera 110 and the adapter device 200 are connected using the video cable 103 and the USB cable 102 so that the digital camera 110 and the adapter device 200 can be arranged freely. However, the invention is not limited to this configuration, and the adapter device may be detachably coupled with the digital camera without using the cables. Such a configuration will be described hereinafter as a

[0124]FIG. 9 is a perspective view of a digital camera 1100 and an adapter device 2000 according to a second embodiment.

[0125]On a side wall 1100a of the digital camera 1100, a video output socket 1240, a USB socket 1220, guide holes 1250 and lock claw inserting holes 1260 are formed. On a side wall 2000a of the adapter device 2000, facing the side wall 1100a of the digital camera 1100, guide pins 2250, locking claws 2260, a video input plug 2240 and a USB plug 2220 are provided. The locking claws 2260 are L-shaped hooking members, which are...

Abstract

A network camera system is configured such that an adapter is connected with a digital camera, and the adapter is connected with a network to which a client is also connected. A video signal representing a real-time image and a digital image signal representing a high-resolution still image are transmitted from the camera to the adapter. The adapter has a function of a file server and allows the client to download image data corresponding to the high-resolution still image. The adapter device further has a function of a streaming server and transmits streaming data representing the real-time image. The client can transmit an operation command to the adapter through the network, and the adapter can transfer the command to the camera to perform the operation required by the client.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application is a Divisional of co-pending U.S. patent application Ser. No. 10 / 385,470, filed Mar. 12, 2003, which claims priority of Japanese Patent Application No. 2002-068434, filed Mar. 13, 2002. The disclosure of each of these documents is expressly incorporated by reference herein in their entireties.BACKGROUND OF THE INVENTION[0002]The present invention relates to an adapter device which is connected to image capturing devices such as video cameras and transmits captured images to image browsing terminals at distant places through a network such as the Internet.[0003]Recently, the broadband Internet such as ADSL or CATV system has become available at a relatively low cost, and an Internet server such as HTTP server and / or FTP server can be used as a home-use server.[0004]Besides the HTTP server and / or the FTP server, a streaming server which transmits a real-time video image captured by a video camera or the like is now ...
