This paper describes development of versatile one-dimensional high-speed video recording camera. It consists of linear-image sensor, frame memory and personal computer. This camera can digitize and store line-image of object at the given period, and resulting images, i. e. time-displacement characteristics of object, can be observed and analyzed through framememory. Maximum sampling clock is 2.048 MHz, and one-line image consists of 512 digitized intensity, so minimum period between line-scannings is 250 μs. This is equivalent to 4000 samples/s and comparable to that of traditional high speed camera. Various image-analysis can be performed with personal computer. Experiments were performed to test this video-recording camera. The objects were free-fall of a steel ball and movement of shutter blades in 35 mm still camera. And characteristics of this system were discussed.
