Abstract
An endoscope system, including: an endoscope for picking up an image of a subject and outputting an image pickup signal of the image; an external processor having a post-signal processing circuit which processes the image pickup signal inputted from the endoscope and generates a video signal that can be outputted to a monitor; and an output detecting circuit for detecting the presence or absence of an output of the image pickup signal and the presence or absence of an output of the video signal.
Claims20
An image pickup system, comprising:
- an image pickup apparatus for picking up an image of a subject and outputting an image pickup signal of the image;
- a signal processing apparatus having a signal processing circuit which processes the image pickup signal inputted from the image pickup apparatus and generates a video signal that can be outputted to a display section;
- and
- an output-detection section for detecting the presence or absence of an output of the image pickup signal and the presence or absence of an output of the video signal.
An image pickup system, comprising:
- an endoscope apparatus, having an endoscope for picking up an image of a subject and outputting an analog image pickup signal of the image, an analog front end for processing the analog image pickup signal and outputting a predetermined number of bits of a digital image pickup signal, an AFE-detection section for detecting if the analog front end is normally operating or not, and a first FPGA that is able to generate a JTAG chain;
- an endoscope signal processing apparatus, having a signal processing circuit for processing the image pickup signal inputted from the endoscope apparatus and generating a video signal that can be outputted to a display section, and a second FPGA that is able to generate a JTAG chain;
- an output-detection section for detecting the presence or absence of an output of the image pickup signal, and the presence or absence of an output of the video signal;
- a connector section that is able to electrically connect the image pickup apparatus and the signal processing apparatus to each other;
- a connection-detection section for detecting the presence or absence of an electrical connection at the connector section using the JTAG chains by the first and second FPGAs;
- and
- a notifying section for notifying at least one of the detection results of the output-detection section, the connection-detection section, and the AFE-detection section.
A method for maintaining an image pickup system that includes an image pickup apparatus and a signal processing apparatus, comprising:
- a video signal detection step for detecting the presence or absence of an output of a video signal from a signal processing apparatus having a signal processing circuit that processes the video signal inputted from the image pickup apparatus for picking up an image of a subject and outputting an image pickup signal of the image via an electrically connectable connector section and outputs the video signal that can be outputted to a display section;
- a connection-detection step for detecting the presence or absence of an electrical connection at the connector section;
- and
- an image pickup signal detection step for detecting the presence or absence of an output of the image pickup signal.
