Title:
MANUFACTURE OF MULTICOLOR FILTER
Document Type and Number:
Japanese Patent JPH03274003
Kind Code:
A
Abstract:
PURPOSE:To obtain an image tube which has superior color reproduction characteristics by inputting the position correspondence relation between the input surface and output surface of the image tube to a camera as position information and manufacturing the multicolor filter which corresponds to the characteristics of the image tube according to the position information. CONSTITUTION:RGB Position information stored in a position information frame memory 45 is read out in synchronism with clock pulses from a clock circuit 33, encoded by an RGB encoder 61, and sent to a color CRT 62. The color CRT 62 has a deflecting coil 63, which is operated by a deflecting circuit 64 according to the synchronizing signal from a synchronizing signal generating circuit 34. Therefore, an image corresponding to the RGB position information stored in the position information frame memory 45 is generated on the display surface 65 of the color CRT 62. This image is inputted to the optical camera 66 ad projected on a film 67. The RGB color filter is therefore manufactured by using this film 67.
