JPS5561179A - Coloring system for moving picture - Google Patents

Abstract

PURPOSE: To realize the moving picture coloring system in which automatic coloring is made only with profile drawing for succeeding pictures, by perfectly coloring the first frame and determining the profile of picture, and providing the means storing the color.

CONSTITUTION: The coloring picture of the first frame picked up at the color pick up tube 10 is demodulated at the color demodulator 12 to produce primary colors R, G, B, signals. The position on the line of the primary colors and the number of orders are calculated at the line order position calculation circuits 13∼15, and the value is stored in the memories 20 ∼22. The line order margin circuits 25∼27 performs margin for the order and the position margin circuits 30∼32 on the line extend the position on the line. The output of the margin circuits is processed and decoded to be analog gate pulse and to enter the AND gates 40∼42, where another input of the gates detects for the pick up signal of the next frame at the profile detection circuit 74. Since this is a signal converted into rectangular signal at FF 75, the gate output can color the part in the profile at the next field.
