摘要： Herein disclosed is a camera recording system which is capable of selectively imaging an image having an aspect ratio - a ratio between the horizontal length and vertical length of a frame - of 4 : 3 as in the NTSC system and an image having a horizontally longer aspect ratio of m : n (m/n > 4/3) than the former ratio. Further disclosed is a usable method which allows the user to take only one turn for selecting the aspect ratio. The method is represented by three kinds: one using a lens unit; another using the scanning range of an image tube; and still another using an expander circuit. What is required of the user is only one turn of switching the lenses or switches, and the remaining necessary switching operations are automated.

摘要： A video signal recording system and method for recording a video signal including a luminance signal (Y), a first color signal (P B ) and a second color signal (P R ) in a plurality of mutually obliquely parallel tracks on a magnetic tape (30). In the system and method, at least two heads (28, 29, 28a, 28b, 29a, 29b) having different azimuth angles forms the plurality of tracks. The luminance signal (Y) and the first color signal (P B ) are processed and then applied to one (28, 28a, 28b) of at least the two heads (28, 29, 28a, 28b, 29a, 29b) having a predetermined azimuth angle to record a signal based on the luminance signal (Y) and the first color signal (P B ) in the tracks formed by the head (28, 28a, 28b) having the predetermined azimuth angle. The luminance signal (Y) and the second color signal (P R ) are processed and then applied to the other (29, 29a, 29b) of at least the two heads (28, 29, 28a, 28b, 29a, 29b) having another azimuth angle different from the predetermined azimuth angles to record a signal based on the luminance signal (Y) and the second color signal (P R ) in the tracks formed by the other head (29, 29a, 29b) having the other predetermined azimuth angle.
