Image sensing control method and apparatus, image transmission control method, apparatus, and system, and storage means storing program that implements the method

An image transmission system including an image sensing control apparatus for transmitting an image signal sensed by an image sensing device to a client via a network, and a plurality of clients,

• the image sensing control apparatus comprising:
• transmission means for transmitting an image signal to a client;
• and
• storage capacity control means for instructing a storage capacity of a buffer for temporarily storing the image signal in the client in accordance with whether the client has the right to access the image sensing device,
• wherein the client switches the storage capacity of the buffer for temporarily storing the image signal in accordance with an instruction instructed by said storage capacity control means.

An image transmission method in an image transmission system including an image sensing control apparatus for transmitting an image signal sensed by an image sensing device to a client via a network, and a plurality of clients,

• the method comprising:
• a determination step of determining whether or not a client being a destination of an image signal has a right of an operation of the image sensing device;
• a process control step of selecting image quality of the image signal from the image sensing device in accordance with a determination result in said determination step and processing the image data based on the image quality;
• and
• a transmission step of transmitting the image signal processed in said process control step to the client via the network, wherein the client requests the image signal sensed by the image sensing device and acquires of the right of an operation of the image sensing device.
