A computer readable memory having control program codes for controlling an image input control apparatus, which is connectable to a plurality of client apparatuses via a network, comprising: storing process procedure codes for storing priority levels of the plurality of clients in a memory; detecting process procedure codes for detecting issuance of a control request of controlling the image sensing apparatus from a client; registering process procedure codes for registering a client who is an issuer of the control request detected in said detecting process procedure, in a waiting queue for obtaining the control privilege of an image sensing apparatus; increasing process procedure codes for increasing an evaluation value of the plurality of clients, who have been registered in said registering step, by a predetermined value at an interval of a predetermined time period; detecting process procedure codes for detecting issuance of a control request of controlling the image sensing apparatus from one of the plurality of clients who have been registered in said registering step; updating process procedure codes for, when the control request is detected in said detecting step, updating contents of the waiting queue on the basis of a registration state of the waiting queue; adding process procedure codes for, each time the waiting queue is updated in said updating step, adding each priority level which is stored in the memory to an evaluation value of each client which is registered in the waiting queue; comparing process procedure codes for comparing an evaluation value of the client who is the top of the waiting queue with an evaluation value of the client who is the issuer of the control request; and providing process procedure codes for, if the evaluation value of the client who is the issuer of the control request is higher than the evaluation value of the client who is the top of the waiting queue as a result of comparison in said comparing step, providing the client who is the issuer of the control request with the control privilege by inserting the client who is the issuer of the control request to the top of the waiting queue.

Claim 47

An image imput system comprising: detecting means for detecting issuance of a request of control privilege of an image sensing apparatus from a client; registering means for registering a client who is an issuer of the control request detected by said detecting means; receiving means for receiving a control privilege abandon notification message from a client registered by said registering means; updating means for updating contents of the waiting queue when said receiving means receives the control privilege abandon notification message.

Claim 48

An image imput system comprising: detecting means for detecting issuance of a request of control privilege of an image sensing apparatus from a client; registering means for registering a client who is an issuer of the control request detected by said detecting means; receiving means for receiving a control privilege abandon notification message from a client registered by said registering means; updating means for updating contents of the waiting queue when said receiving means receives the control privilege abandon notification message.

Claim 49

A controlling method of an image input system comprising the steps of: detecting issuance of a request of control privilege of an image sensing aparatus from a client; registering a client who is an issuer of the control request detected in the detecting step; receiving a control privilege abandon notification message from a client registered in the registering step; updating contents of the waiting queue when the control privilege abandon notification message is received in the receiving step.

Claim 50

A controlling method of an image input system comprising the steps of: detecting issuance of a request of control privilege of an image sensing aparatus from a client; registering a client who is an issuer of the control request detected in the detecting step; receiving a control privilege abandon notification message from a client registered in the registering step; updating contents of the waiting queue when the control privilege abandon notification message is received in the receiving step.

Claim 51

A computer readable memory having control program codes for controlling an image input system, comprising: detecting process procedure codes for detecting issuance of a request of control privilege of an image sensing apparatus from a client; registering process procedure codes for registering a client who is an issuer of the control request detected in said detecting process procedure; receiving process procedure codes for receiving a control privilege abandon notification message from a client registered in said registering process procedure; updating process procedure for updating contents of the waiting queue when the control privilege abandon notification message is received in said receiving process procedure.

Claim 52

A computer readable memory having control program codes for controlling an image input system, comprising: detecting process procedure codes for detecting issuance of a request of control privilege of an image sensing apparatus from a client; registering process procedure codes for registering a client who is an issuer of the control request detected in said detecting process procedure; receiving process procedure codes for receiving a control privilege abandon notification message from a client registered in said registering process procedure; updating process procedure for updating contents of the waiting queue when the control privilege abandon notification message is received in said receiving process procedure.
