Method of converting two-dimensional images into three-dimensional images

A method of converting two-dimensional images into three-dimensional images by producing from a two-dimensional image signal a main image signal and a sub-image signal delayed from the main image signal, comprising the steps of:

• previously storing a plurality of types of tables representing the relationship between the speed of the movement of an image and a field delay, and providing inputting means for designating a predetermined table out of the plurality of types of tables,
• calculating the speed of the movement of the main image signal for each field,
• finding a field delay on the basis of the table designated by the inputting means and the speed of the movement in the current field of the main image signal, and
• determining a field delay from the main image signal to the sub-image signal in the succeeding field on the basis of the found field delay.

A method of converting two-dimensional images into three-dimensional images by producing from a two-dimensional image signal a main image signal and a sub-image signal delayed from the main image signal and subjecting the main image signal and the sub-image signal to phase shift in the horizontal direction, comprising the steps of:

• previously storing a plurality of types of tables representing the relationship between the speed of the movement of an image and a field delay and an amount of phase shift predetermined for each table, and providing single inputting means for designating a predetermined table out of the plurality of types of tables and at the same time, designating an amount of phase shift corresponding thereto;
• calculating the speed of the movement of the main image signal for each field;
• finding a field delay on the basis of the table designated by the inputting means and the speed of the movement in the current field of the main image signal;
• determining a field delay from the main image signal to the sub-image signal in the succeeding field on the basis of the found field delay;
• and
• subjecting the main image signal and the sub-image signal delayed by said determined field delay from the main image signal to phase shift in the succeeding field depending on the amount of phase shift designated by the inputting means.

A method of converting two-dimensional images into three-dimensional images by producing from a two-dimensional image signal a main image signal and a sub-image signal delayed from the main image signal, comprising the steps of:

• previously producing a relational expression for finding a field delay on the basis of three-dimensional effect adjusting data and the speed of the movement of an image, and providing inputting means for inputting the three-dimensional effect adjusting data;
• calculating the speed of the movement of the main image signal for each field;
• finding a field delay on the basis of the adjusting data inputted by the inputting means, the speed of the movement in the current field of the main image signal, and the relational expression previously produced;
• and
• determining a field delay from the main image signal to the sub-image signal in the succeeding field on the basis of the found field delay.
