Display system with 2D/3D image conversion where left and right eye images have a delay and luminance difference base upon a horizontal component of a motion vector

A method of converting two-dimensional images into three-dimensional images comprising:

• producing from a two-dimensional image signal a first image signal and a second image signal a luminance of which is attenuated from the first image signal and taking one of the signals as a left eye image signal and the other signal as a right eye image signal;
• an image represented by said two-dimensional image signal includes a moving portion,
• an amount of attenuation of the luminance of the second image signal from the first image signal being determined on the basis of the speed of the movement in the moving portion wherein the speed is determined based on a horizontal component of a motion vector which is detected from the first image signal,
• the higher the speed of the movement in said moving portion is, the smaller said amount of attenuation of the luminance is, while the lower the speed of movement in the moving portion is, the large the amount of attenuation of luminance is.

A 3D image display system comprising:

• a 2D/3D image converter for converting two-dimensional images into three-dimensional images by producing from a two-dimensional image signal a right eye image signal and a left eye image signal between which there is a relative time difference;
• and wherein an image represented by said two-dimensional image signal includes a moving portion;
• wherein delay is indicated by how many fields there are from a field corresponding to the first image signal to a field corresponding to the second image signal as relating to the speed of the movement in said moving portion wherein the speed is determined based on a horizontal component of a motion vector which is detected from the first image signal;
• wherein the higher the speed of the movement in said moving portion is, the smaller said delay is, while the lower the speed of the movement in the moving portion is, the larger the delay is;
• and
• a display for realizing three-dimensional images on the basis of the right eye image signal and the left eye image signal which are obtained by the 2D/3D image converter.
