Abstract
A blood-vessel endoscope system has an endoscope to be inserted into a blood vessel in a living body and a frozen-picture memorizing device connected to the endoscope, and is capable of storing a frozen picture when a release switch is actuated. The system is provided with a frozen-picture memorization controlling device so that a frozen picture free from a large blur may be stored in synchronization with the signal output from a heart pulsation measuring device for measuring the heart pulsation of the living body and at the timing that the action of a myocardium is reduced.
