Patent ID: 7149423

Claim:
A lens apparatus diagnostic system, comprising: a lens apparatus including: a detection device which detects information necessary for a diagnosis from each drive member of the lens apparatus; a first communication device which performs digital two-way communication; and a first control device which operates the drive members according to a control signal inputted via the first communication device and outputs the information detected by the detection device via the first communication device; and a computer externally connected to the lens apparatus including: a second communication device which performs communication with the first communication device of the lens apparatus; a display device; a storage device which stores a diagnostic program; and a second control device which has the diagnostic program executed to operate each of the drive members of the lens apparatus and performs the diagnosis by gathering the information detected by the detection device so as to have diagnostic results thereof displayed on the display device; a selection device which selects one of a diagnostic mode to diagnose the lens apparatus and a control mode to externally control the lens apparatus; an operating portion which operates each of the drive members of the lens apparatus while in the control mode; a device which outputs the control signal according to operation of the operating portion to the lens apparatus via the second communication device; and another device which outputs mode information indicating which of the diagnostic mode and the control mode is selected by the selection device to the lens apparatus via the second communication device, and wherein the lens apparatus detects information necessary for the diagnostic from each of the drive members upon determining the drive members are in the diagnostic mode according to the mode information inputted via the first communication device, and detects from each of the drive members only the information necessary to control the drive members upon on determining the drive members are in the control mode.
