Title: Projection display device
Inventor: TANAKA TAKAAKI
IPC: G02F1/13
Filed: 1992-04-07
Abstract: PURPOSE:To provide a projection display device without generating color nonuniformity in a projection image and with high brightness. CONSTITUTION:Light from a light source 20 is separated to light of blue, green, and red by a color separation optical means 27, and they are made incident on light valves 35-37 after transmitting field lenses 29-31. Optical images on the light valves are projected by enlarging on a screen by three projection lenses 38-40. A lens 28 whose power in a center part is positive and including an aspherical surface with high curvature in the center part compared with that in a peripheral part is provided in optical paths of green and red. Therefore, it is possible to set the illuminance distribution of blue, green, and red on the screen in each color light equal by the lense 28, which remarkably reduces the color nonuniformity in a synthetic projection image.

Title: Driving method of display device, and display device
Inventor: ENDO HIROAKI
IPC: G02F1/133
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To eliminate obstruction of lateral stripes arising from polar inversion by a line inversion drive system by making the polarity of display data to be supplied to display elements differ at every adjacent dot at least in a part of the same line, at every line period, and at every field period (or at every frame period). SOLUTION: For example, an left upper end picture element is driven to sequentially repeat the inversion like +, -, +, - with a field period from the 1st field. And, a voltage waveform polarity of the picture elements adjacent to the one to which attention is paid is controlled so as to be inverted with respect to the latter. In each field, the voltage waveform polarity is inverted every line. Thus, by dot inversion drive, voltage of different polarities is impressed on adjacent picture elements in each line, and the polarities are averaged between the adjacent picture elements, and as a result, such a display averaged in the line becomes possible and the obstruction of lateral stripes is eliminated.

Title: Color image processing device

IPC: H04N1/48
Filed: 1988-04-07
Abstract: PURPOSE:To eliminate the deterioration of black character reproducibility and achieve the retrieval of high-quality images using comparatively simple hardware by detecting edges using combined signal of color and black signals. CONSTITUTION:Signals y, m, c, k from a background color removal circuit 20 are entered into a selector circuit 209, and in this circuit, only signals of the same type are selected from the signals y, m, c, k based on a developed color signal (d). The selected signals are output to an edge detection circuit 211 after being delayed by four video lines in a four-line buffer 210. An adder 208 combines either one of signals y, m, c obtained by the background color removal circuit 202, and a signal (k) by the addition processing to produce a combined signal, and outputs this combined signal to the selector circuit 208 and a color detection circuit 213 of the edge detection circuit 22. The edge detection circuit detects the edge based on the combined signal. If the (k) component after the removal of the background color is insufficient due to the shift of parameters for intermediate tone reproduction or the offset of input signals, the black edge can be detected accurately.

Filed: 1988-04-08
Abstract: PURPOSE:To improve vacuum adhesiveness, to simplify a plate making stage and to decrease the fatigue of a developing soln. by providing a discontinuous matte layer fixed with solid particles on a silicone rubber layer. CONSTITUTION:This printing plate material has a photosensitive layer 2 and the silicone rubber layer 3 on a base 1 and has the discontinuous matte layer 4 fixed with the solid particles on the silicone rubber layer 3. Namely, this material is constituted by having the discontinuous matte layer fixed with the solid particles on the silicone rubber layer and, therefore, not only the vacuum adhesiveness is improved but also the stage of stripping rugged transparent films after exposing is eliminated. The plate making stage is consequently simplified and the degradation of halftone reproducibility is obviated. Since the solid particles insoluble in the developing soln. are used, the solid particles are easily separated by means such as filtration after development even if the solid particles intrude into the developing soln. The fatigue of the developing soln. is thus decreased.
