20130016118 | IMAGE PROCESSING METHOD, IMAGE PROCESSOR, AND IMAGE DISPLAY SYSTEMAANM Mizushiro; KenjiAACI Matsumoto-shiAACO JPAAGP Mizushiro; Kenji Matsumoto-shi JP - An image processing method, which performs color correction on a superimposed image obtained by superimposing a first image formed by a first image forming unit and a second image formed by a second image forming unit, includes controlling the dimming of the first image forming unit and the second image forming unit on the basis of dimming rates set in the first image forming unit and the second image forming unit in response to a given designated dimming rate, and performing a color correction process on image signals corresponding to the first image forming unit and the second image forming unit using a color correction value corresponding to the dimming rates of the first image forming unit and the second image forming unit. | 01-17-2013 |
20140085438 | STEREOSCOPIC SPECTACLES CONTROL DEVICE, DISPLAY DEVICE, AND STEREOSCOPIC SPECTACLES CONTROL METHOD - A phase error detection unit measures a phase error between an external synchronization signal and a spectacles control signal that is fed back, more specifically, a discrepancy between vertical synchronization timing and shutter opening/closing timing, that is, jitter. A timing correction unit corrects the shutter opening/closing timing, using the measured jitter. Specifically, a parameter indicating the corrected shutter opening/closing timing is written to a storage unit. The storage unit stores a parameter used to generate the spectacles control signal, for example, the parameter indicating the shutter opening/closing timing. A signal generation unit generates the spectacles control signal, using the parameter stored in the storage unit. A frequency divider divides the frequency of the spectacles control signal by n. | 03-27-2014 |
20140210869 | DISPLAY DEVICE AND DISPLAY CONTROL METHOD - A display device includes a light modulation device, a light source, a light modulation device control section, and a light source control section. The light modulation device control section controls the light modulation device to select a plurality of scan lines of the light modulation device by K lines (K is an integer not smaller than 2), and write a data signal into the pixels corresponding to the selected scan lines in an image update period, and to select at least a part of the plurality of scan lines line by line, and then write the data signal into the pixels corresponding to the selected scan line in an image display period subsequent to the image update period. The light source control section sets a duty ratio in a part of the image display period to be higher than the duty ratio in another part of the image display period. | 07-31-2014 |
