Abstract
A framing camera comprises a photocathode, a first deflection means for scanning electron beams emitted from the photocathode, a slit plate having a single slit for converting the electron beams with a spatial picture image information into electron beams with a picture image of temporal sequence and a second deflection means for scanning the electron beams passed from the slit plate to have them impinge upon a phosphor screeen to thereby produce a plurality of framed patterns, in which deflection voltages supplied to the first and second deflection means are adjustable independently of each other.
