Abstract
A control device includes: generation circuitry configured to output a field signal to a medical imaging device; first detection circuitry configured to detect a horizontal synchronization signal from video data output from the medical imaging device, the video data including at least the horizontal synchronization signal; and a monitoring circuitry configured to monitor whether or not an abnormality occurs in one frame period of the video data based on a period of the horizontal synchronization signal detected by the first detection circuitry for a predetermined n-th time after polarity of the field signal is switched.

- acquiring an identification signal for identifying a type of the medical imaging device;
- determining based on the identification signal whether or not a vertical synchronization signal is included in the video data;
- detecting a horizontal synchronization signal from video data output from the medical imaging device, the video data including at least the horizontal synchronization signal;
- and
- monitoring whether or not an abnormality occurs in one frame period of the video data based on a period of the horizontal synchronization signal detected for a predetermined n-th time after polarity of the field signal is switched.
A control device comprising:
- generation circuitry configured to output a field signal to a medical imaging device;
- first detection circuitry configured to detect a horizontal synchronization signal from video data output from the medical imaging device, the video data including at least the horizontal synchronization signal;

- and
- a controller configured to
- acquire an identification signal for identifying a type of the medical imaging, device, and
- determine based on the identification signal whether or not a vertical synchronization signal is included in the video data.
A control method executed by a control device that includes a processor having hardware and to which a medical imaging device is connected, the control method comprising:
- outputting a field signal to the medical imaging device;
- acquiring an identification signal for identifying a type of the medical imaging device;
- determining based on the identification signal whether or not a vertical synchronization signal is included in the video data;
- detecting a horizontal synchronization signal from video data output from the medical imaging device, the video data including at least the horizontal synchronization signal;
- and
- monitoring whether or not an abnormality occurs in one frame period of the video data based on a period of the horizontal synchronization signal detected for a predetermined n-th time after polarity of the field signal is switched.
