Document Type and Number:
Japanese Patent JPS55130051
Kind Code:
A
Abstract:
PURPOSE: To improve the quality of image pickup screens due to beating by analyzing the beat shape at the time when a two-group stripe filter intersects and specifying each fixed area for the angle of intersection and the beat generation direction or beat periodicity.
CONSTITUTION: A two-group stripe color filter is formed by intersecting and overlapping a cyanic stripe filter 1 and 9 yellow stripe filter 2. The space frequency of the optical beat formed by this two-group stripe filter exceeds the approximately 60% of the television system threshold resolution frequency in the direction of beat arrangement.
