Abstract
A 3D image control apparatus is provided which prevents unevenness of luminance in an observed image on a screen caused in a 3D image viewing system including an impulse type display device and liquid crystal shutter glasses. The 3D image control apparatus includes an image processing unit configured to generate luminance signals for displaying a right eye image and a left eye image on the basis of an input image signal and output the signals to a display unit. The image processing unit performs arithmetic operation on an image signal corresponding to pixels on a predetermined number of vertical lines using correction values for increasing a luminance in accordance with the position of each vertical line so that a lack of transmittance for a rising period or falling period of shutters of liquid crystal shutter glasses is compensated for, thus generating luminance signals.
