Endoscope system

摘要

An endoscope system has an image pickup section and a processor. The image pickup section has a control register section which controls a sensor section, a nonvolatile memory which stores first setup data, a control signal interface section which sets the first setup data in the control register section, and an initialization check register which senses an abnormality in the control register section. When an abnormality is sensed, the control signal interface section reads out the setup data from the nonvolatile memory and performs control so as to reset the setup data in the control register section. The control signal interface section further has a memory which stores reset occurrence information upon occurrence of reset. The processor includes a control section which reads out the reset occurrence information from the memory, and, when reset is detected, transmits second setup information held by the processor to the image pickup section.

主权项

1. An endoscope system comprising:
an image pickup apparatus including an image pickup device which picks up an image of an object and a processor connected to the image pickup apparatus, wherein the image pickup apparatus includes an image pickup device control section which controls the image pickup device, a storage section which stores first image pickup device control information to be set in the image pickup device control section, an image pickup device control information setting section which sets the first image pickup device control information stored in the storage section in the image pickup device control section, a pulse generating section which generates a first pulse for driving the image pickup device based on the first image pickup device control information set in the image pickup device control section, a period counter which resets a second pulse corresponding to the first image pickup device control information stored in the storage section, by the first pulse generated by the pulse generating section, to produce the second pulse with the same period as the first pulse, a comparison section which compares a period of the first pulse and a period of the second pulse, and determines an abnormality in the first image pickup device control information set in the image pickup device control section by the image pickup device control information setting section and outputs an abnormality determination signal if the period of the first pulse is longer or shorter than the period of the second pulse, an image pickup device control information resetting section which reads out the image pickup device control information from the storage section and controls the image pickup device control information setting section to reset the image pickup device control information in the image pickup device control section when the abnormality determination signal is inputted from the comparison section, a reset occurrence information storage section which stores reset occurrence information upon occurrence of the reset by the image pickup device control information resetting section, and a first communication section which transmits and receives information to and from the processor, and the processor includes a second communication section which transmits and receives information to and from the image pickup apparatus; and an image pickup device control information retransmission section which reads out the reset occurrence information from the reset occurrence information storage section through the second communication section and the first communication section and, when reset is detected, transmits second image pickup device control information held by the processor to the image pickup apparatus through the second communication section and the first communication section.
