20090091612 | Stereoscopic Image Reproducing Device and Method, Stereoscopic Image Reproducing Program, And Recording Medium Having The Program Recorded Therein - The present invention is directed to a stereo image processing apparatus adapted for performing stereoscopic reproduction of images without depending upon header information of file to have ability to recover or restore header information for stereoscopic display which has been broken or missing, which includes an image input unit ( | 2009-04-09 |
20090091613 | Asymmetric viewing angles for a dual view display - The present invention is related to an asymmetric aligned display having asymmetric viewing angles. The present invention provides a dual-view or 3D display capable of displaying two images of unrelated or related content along different directions with asymmetric viewing angles. The asymmetric viewing angles of the display device of the present invention can be realized by the introduction of multiple sub-pixel pitches into a single display. To be more specific, the present invention provides an asymmetric aligned display by realizing the asymmetry design in the sub-pixel itself. Consequently, the angular extends of the respective viewing windows or images displayed along different directions can be different or asymmetrical. The asymmetric aligned display of the present invention is, therefore, capable of displaying images along different directions with asymmetric viewing angles and windows without affecting the outer boundaries of the viewing windows. | 2009-04-09 |
20090091614 | BIOLOGICAL OBSERVATION APPARATUS - A biological observation apparatus comprising: an illuminating section that irradiates light to a living body that is a subject to be examined; an image pickup section that photoelectrically converts light reflected from the living body based on the irradiating light and creates an image pickup signal; and a signal processing control section that controls operations of the illuminating section and/or the image pickup section and outputs the image pickup signal to a display device, wherein the signal processing control section includes: a spectral signal creating section that creates a spectral signal corresponding to an optical wavelength narrowband image from the image pickup signal through signal processing; and a color adjusting section that, when outputting the spectral signal to the display device, allocates a different color tone for each of a plurality of bands forming the spectral signal, further wherein the biological observation apparatus further comprises an image quality adjusting section that adjusts an image quality of a signal to be outputted to the display device, or, with the exception of at least the spectral signal creating section and the color adjusting section, the other signal processing sections are shared for respective signal processing on the image pickup signal and on the spectral signal. | 2009-04-09 |
