发明名称 3D image display apparatus and control method for same
摘要 A 3D image display has a display unit which is driven so as to emit light in a line-sequential or a block-sequential manner; a storage unit which stores characteristics information relating to temporal change in transmittance of a liquid crystal shutter glasses with respect to light of respective primary colors in the display unit; and a correction unit which corrects an input image signal of the respective primary colors using the characteristics information, so as to reduce color fluctuation between lines or between blocks in the observed image caused by differences in the temporal change of the transmittance of the liquid crystal shutter glasses in respect of each of the primary colors, wherein the display unit displays a corrected image based on a corrected image signal generated by the correction unit.

主权项 1. A 3D image display apparatus for causing a left eye image and a right eye image that are displayed by a frame-sequential method to be observed through liquid crystal shutter glasses, the apparatus comprising: a display unit which is driven to emit light in a line-sequential or a block-sequential manner; a storage unit which stores characteristic information relating to temporal change in transmittance of the liquid crystal shutter glasses with respect to light of respective primary colors in the display unit; and a correction unit which corrects an input image signal of the respective primary colors using the characteristic information, to reduce color fluctuation between lines or between blocks in the observed image caused by differences in the temporal change of the transmittance of the liquid crystal shutter glasses in respect of each of the primary colors, wherein the display unit displays a corrected image based on a corrected image signal generated by the correction unit, the liquid crystal shutter glasses have characteristics by which the transmittance with respect to light of a first primary color gradually increases, and the correction unit generates the corrected image signal such that a brightness of a corrected image becomes higher the earlier the line or block is arranged in the sequence of light emission, when an image signal of only the first primary color is input.
