Title: Transformation method from two-dimensional image into three-dimensional image
Inventor: YAMASHITA SHIYUUGO
IPC: H04N13/00
Filed: 1995-02-17
Abstract: PURPOSE: To decrease the number of field memories by writing a main image in a field memory, field by field, when the movement of the main image is fast, and at intervals of several fields when slow. CONSTITUTION: A two-dimensional image signal (a) is sent to a motion vector detecting circuit 16, plural field memories 11, and a selector 17 respectively, and data generated by the circuit 16 are sent to a CPU 20. The CPU 20 calculates the number of delay fields in the memories 11 on the basis of a motion vector. When the motion vector is large, the delay quantity is made small and when the motion vector is small, the delay quantity is made large and thus determined. For an image of fast motion, its input video signal is written in the memories 11 without thinning out fields. For an image of slow motion, fields are thinned out and the input video image is written in the memories 11. Consequently, the number of the memories is reduced from 6 to 3.
