CONFERENCE PROCEEDINGS FREE ACCESSDigital broadcast begins substantially soon in U.S. and Japan. Multiples exist in digital broadcast, HDTV and SDTV are selected every program and be broadcasted. It is hoped that the multiformat is obtained from 1 studio camera in program production. It is generally difficult to realize multiformat while maintaining performance and stability. We adopt the method that gets the output of 1080i, 480P, and 480i by switching the drive mode of 1080iCCD. We report the 1080iCCD drive method, the signal processing and also transmission technology.View full abstractDownload PDF (591K) -

CONFERENCE PROCEEDINGS FREE ACCESSTwo kinds of Electron Bombardment CCD (EB-CCD) camera are newly developed, employing an Electron Bombardment CCD sensor made by Hamamatsu Photonics. The slow scan cooled CCD camera installs the full frame transfer type EB-CCD sensor with 512×512 pixel format and standard video rate camera installs the frame transfer type EB-CCD sensor (progressive scan) with 658×490 pixel format. These cameras have been compared with the other high sensitive camera like SIT camera, photon counting camera and I-CCD camera which results in proving that these Electron Bombardment CCD camera are suitable and idealView full abstractDownload PDF (700K) -

CONFERENCE PROCEEDINGS FREE ACCESSA HARP (High-gain Avalanche Rushing amorphous Photoconductor) film for use in a solid-state imager was studied. A thin HARP film must be developed because the available bias voltage of the film in a solid-state imager is restricted below 60 V, which is the endurance voltage of readout MOS transistors at present. We estimated that the suitable thickness of the film was 0.4μm. And by using the experimental tube, we confirmed an avalanche gain of four at a bias voltage of 60 V. No deterioration of the spectral response characteristics of an imager with the thin HARP film was observed, but it was found that the quantum efficiency was low at the green and red wavelengths. To increase the sensitivity of the thin 0.4-μm HARP film, we designed a tellurium (Te)-doped HARP film by using the simulations of the quantum efficiency. These simulations showed that the sensitivity of the film could be more than doubled over conventional levels for green light.View full abstractDownload PDF (1514K) -

CONFERENCE PROCEEDINGS FREE ACCESSA type of 3D camera was proposed and the performances were evaluated. The camera adds the depth information to each pixel of an ordinary two dimensional television image. The camera uses a combination of a high-speed shutter with intensity modulated illuminator. As a result of experiments, it was verified that the depth information was obtained independent of the reflectivities or the shape of the objects. The results of experiments using several kinds of targets suggest a possibility developing this to a 3D TV camera.View full abstractDownload PDF (619K) -

CONFERENCE PROCEEDINGS FREE ACCESSTFT back-channel threshold voltage is increased and the TFT leakage is effectively suppressed by the SiOxNy deposition. TEM observation, hole-conduction ignition voltage and back channel conductance analysis reveals that the leakage suppression is due to the charge created at the onset of the SiOxNy deposition. Vgh and Vgl margin improvement after driving stress is also mentioned.View full abstractDownload PDF (465K) -

CONFERENCE PROCEEDINGS FREE ACCESSA method to enlarge the allowable range of marginal variation of the cell gap to ensure uniform brightness of in-plane switching mode liquid crystal displays is proposed. The proposed method is based on enlargement of the effective cell gap using the extrapolation length that is generated with weak-anchoring effects at liquid crystal/alignment layer interfaces. The method is evaluated with simulations and experiments. The results support the effectiveness of the method.View full abstractDownload PDF (516K) -

CONFERENCE PROCEEDINGS FREE ACCESSWe investigated viewing angle characteristics of Super-TFT-LCD monitors, and the difference of display size between LCD and CRT by ergonomic measurements. The Super-TFT monitors had wide viewing angle of contrast, brightness, grayscale non-inversion range and small color sift. These display characteristics induced wide tolerable viewing ranges in the pattern of characters, figures and pictures. The display size of 13.9" TFT-LCD corresponds to 17" CRT display.View full abstractDownload PDF (696K) -

CONFERENCE PROCEEDINGS FREE ACCESSAn autostereoscopic display using dynamic double parallax barrier (DDPB) that can be attached to CRT displaying field-sequential stereoscopic images, is developed. DDPB panel can be easily attached or removed without concerning geometrical limitations for CRT pixel positions. Normal (two-dimensional TV broadcasting signal) can be also observed by removing the panel from CRT. Furthermore, a method to detect an observer head position using an active sensing (infrared) to realize a wide autostereoscopic viewing area, is developed.View full abstractDownload PDF (703K) -
