摘要： PROBLEM TO BE SOLVED: To perform the stable switching of colors by scanning the right and left screens from the right and left sides respectively to detect the index signals which are applied at the over-scan parts. SOLUTION: A left screen 23 and a right screen 24 consist of two electronic guns 21 and 22 respectively. An index fluorescent material 27 which emits the ultraviolet rays is applied at the over-scan parts 25 and 26 of a screen, and the light emitted from the material 27 is received by a photodetector, e.g. a photodiode. Then the screens 23 and 24 are scanned from the right and left sides respectively, and the index signals are detected at the scan starting position. Thus the index signals can be detected before the horizontal scan is started owing to the index areas prepared at both parts 25 and 26. Thereby, the switching of colors can be instructed to every switching circuit with margins.

摘要： PROBLEM TO BE SOLVED: To detect an electronic beam at other position without changing an index phosphor by applying electronic beam scanning over two adjacent detection elements in the scanning direction of a cathode ray tube so as to detect the scanning position. SOLUTION: A pattern B signal 11 outputted from a pattern B signal generating circuit 106 is projected onto a detection element formed by coating a phosphor onto a cathode ray tube 1 in a chevron shape. The element 3 stimulates a light, the light is converted into an electric signal by a photoelectric conversion circuit 101 and a detection signal is outputted. An output of a vertical position detection pulse interval measurement circuit 103 receiving the detection signal is inverted by an inversion circuit 104 and a changeover circuit 702 receiving the pattern B signal 11 is used to provide the inverted signal to an arithmetic control circuit 200. A geometrical distortion correction circuit 300 takes a difference from an object value to correct geometrical distortion.

摘要： PURPOSE: To reproduce a good color image by controlling the operation of each electron gun and that of each deflecting device so that scanning of electron beams over a plurality of areas into which one screen part is divided, and switching of colors are performed using time division. CONSTITUTION: An electron beam 18 emitted from each electron gun 15 is deflected by horizontal and vertical magnetic fields produced by each deflecting yoke 16, to scan one screen part 13 while dividing it into a plurality of regions. The electron beams 18 emitted from the twelve electron guns 15 disposed within the necks 14 of twelve funnels 11 are deflected by the magnetic fields produced by the twelve deflecting yokes 16, so that the screen part 13 is scanned while being divided horizontally into four and vertically into three, a total of twelve regions. This division into the regions is controlled based on signals transmitted from a control part controlling the operation of each electron gun 15 and yoke 16. Thus a continuous color image that has no gaps and overlaps is displayed on the screen part 13.

摘要： PROBLEM TO BE SOLVED: To automatically execute various corrections in a color television receiver, to realize highly precise correction and to drastically shorten adjusting time. SOLUTION: Plural index phosphors 6 are arranged on the surface of a shadow mask 4 so that the intervals of adjacent two points become narrow in accordance with the increase of a polarizing angle. Radiation output is changed in accordance with the scanning of an electronic beam and the radiation output is detected by a photoelectric conversion element provided in a cathode- ray tube. A test signal modulated by the electronic gun 2 of G is set to be a reference signal, test signals modulated by the electronic guns 1 and 3 of R and G are set to be convergence signals, the light emission of the index phosphors 6 is set to be an index signal and the two-dimensional position of the signal is detected. A geometrical distortion and convergence are corrected by using position information.
