Abstract
A server which smoothly transmits/receives a moving image from image sensing device via the Internet. The server comprises a camera which converts an object image into an image signal, a camera controller which controls the camera, and a camera driver. When the image signal converted by the camera is transferred as still-image data on the Internet, the data is transferred by the HTML or HTTP protocol, on the other hand, when the image signal is transferred as moving-image data, the data is transferred by another protocol.
Claims30
A server comprising:
- control means for controlling image sensing means for converting an object image into an image signal;
- first transmission means for transmitting a real-time image signal converted by said image sensing means, as still-image data, by a first protocol corresponding to the Internet;
- and
- second transmission means for transmitting the real-time image signal converted by said image sensing means, as moving-image data, by a second protocol, corresponding to the Internet, different from the first protocol.
A terminal apparatus which performs communication with a server having control means for controlling image sensing means for converting an object image into an image signal, first transmission means for transmitting the real-time image signal converted by said image sensing means, as still-image data, by a first protocol corresponding to the Internet, and second transmission means for transmitting the real-time image signal converted by said image sensing means, as moving-image data, by a second protocol, corresponding to the Internet, different from the first protocol, comprising:
- output means for outputting an operation instruction signal to said control means;
- first reception means for receiving the image signal by the first protocol;
- and
- second reception means for receiving the image signal by the second protocol.
A server control method comprising:
- a control step of controlling image sensing means for converting an object image into an image signal;
- a first transmission step of transmitting the real-time image signal converted by said image sensing means, as still-image data, by a first protocol corresponding to the Internet;
- and
- a second transmission step of transmitting the real-time image signal converted by said image sensing means, as moving-image data, by a second protocol, corresponding to the Internet, different from the first protocol.
A method for a terminal apparatus which performs communication with a server which controls image sensing means for converting an object image into an image signal, transmits the real-time image signal converted by said image sensing means, as still-image data, by a first protocol corresponding to the Internet, and transmits the real-time image signal converted by said image sensing means, as moving-image data, by a second protocol, corresponding to the Internet, different from the first protocol, comprising:
- a first reception step of receiving the image signal by the first protocol;
- a second reception step of receiving the image signal by the second protocol;
- and
- an output step of outputting an operation instruction signal to said image sensing means.
