Abstract
A method of converting two-dimensional images into three-dimensional images. When the movement of a main image is fast, a main image signal is written into field memories for each field. When the movement of the main image is slow, the main image signal is written into the field memories at intervals of a predetermined number of fields. An image to be read out as a sub-image from the field memories is determined on the basis of the speed of the movement of the main image.

A method of converting two-dimensional images into three-dimensional images by producing from a two-dimensional image a main image and a sub-image delayed from the main image utilizing field memories, comprising the steps of:
- writing the main image into the field memories for each field when the movement of the main image is fast;
- writing the main image into the field memories at intervals of a predetermined number of fields when the movement of the main image is slow;
- and
- determining an image to be read out as the sub-image from the field memories on the basis of the speed of the movement of the main image.
A method of converting two-dimensional images into three-dimensional images by producing from a two-dimensional input image a main image and a sub-image delayed from the main image, comprising the steps of:
- providing field memories for storing the two-dimensional input image in units of fields;
- writing the two-dimensional input image into the field memories for each field when the movement of the two-dimensional input image is fast;
- writing the two-dimensional input image into the field memories at intervals of a predetermined number of fields when the movement of the two-dimensional input image is slow;
- and
- selecting the main image out of the two-dimensional input image and images in the field memories and selecting the sub-image out of the images in the field memories so that a field delay from the main image to the sub-image becomes a value determined on the basis of the speed of the movement of the two-dimensional input image.
