Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 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 l…
