摘要： PURPOSE:To remove the discontinuous part and to have the same inclination in a horizontal deflecting current during an effective scanning period by passing all current passing through a damper diode to a bidirectional switching element. CONSTITUTION:In place of a horizontal deflecting output transistor and the damper diode, a MOSFET 6 as the bidirectional switching element is used. The terminal voltage VC of a capacitor C1 is compared with a reference voltage VS, when the voltage VC exceeds the VS, a signal SC is outputted from a comparator 7. According to the rise of this signal SC, a monostable multivibrator 8 having a time constant tauS is triggered to obtain a pulse P1 of a pulse duration tauS. This pulse P1 and a horizontal driving pulse HD are applied to an OR circuit 9 and this output pulse P2 is applied to the gate electrode of an FET6. Thereby, the difference in the effective scanning period is eliminated to obtain the horizontal deflecting current having to constant inclination.

摘要： PURPOSE: To offer a correction circuit not requiring readjustment even when the installation is changed between installation mounting and ceiling mounting by inputting a horizontal and a vertical convergence correction base signal SH, SV at installation mounting (or ceiling mounting) and inputting an inverted signal of the said signal at ceiling mounting (or installation mounting) by an input switching circuit.
CONSTITUTION: Interlocking changeover switch circuits 81, 82 of the input changeover circuit 80 are thrown to input terminals 81a, 82a to which the horizontal and vertical sawtooth wave signals SH, SV are incoming when a projector is at installation mounting, and changed over to other input terminals 81b, 82b to which signals ISH, ISV being the inversion of the signals SH and SV by inverters 83, 84 are given at the ceiling mounting. Thus, when a switching control signal COH1 is at 'H', a variable resistor VRL to which the signal ISH is given via a switching circuit 2 gives a convergence correction signal SL when the scanning is positioned at the left side L of the screen. That is, the variable resistor VRL gives the correction signal SL when the scanning is positioned at the left side L of the screen independently of the ceiling mounting or installation mounting.

摘要： PURPOSE:To attain accurate convergence over the entire range of screen by forming a convergnece correcting signal whose discontinuous point is placed during the horizontal synchronizing period. CONSTITUTION:An affirmative output Q2 of an FF22 in place of a horizontal synchronizing signal is fed to a reference generator 9 as an oscillation stop control signal. Further, an affirmative output Q1 of an FF21 is used as a count pulse of a vertical address counter 3 and a reset pulse of a horizontal address counter 2. Through the constitution above, the convergence correcting signal obtained by an A/D converting circuit 5 has a waveform in which the discontinuous point between the convergence correcting signal of a horizontal scanning line 1 and the convergence correcting signal of the next horizontal scanning line is placed during the horizontal synchronizing period as shown in A. Further, a drive current without distortion at the start point of the next one horizontal scanning line as shown in B folws to a convergence coil 8.

摘要： PURPOSE:To prevent the deterioration of vertical image resolution by detecting the vertical correlation from the present video signal and video signals preceding and following by a horizontal period to the present signal and performing the scan with coincidence obtained between two electron beams in case the non- correlation has the value higher than a prescribed level. CONSTITUTION:A video signal SV is separated into a luminance signal Y and a color signal C by a Y/C separating circuit 22. The signal Y is delivered to a correlation detecting circuit 100. The circuit 100 detects the non-correlation value between the present video signal and another video signal which is preceding or following by a horizontal period to the present signal and then set an output signal SC at ''0'' when the non-correlation value is lower than a prescribed level. Each of projection type CRT 1R-1B which produce red, green and blue pictures respectively has two electron beam generating sources K1 and K2 to perform the non-interlace scan on a fluorescent screen. In case the vertical correlation is weak and the signal SC is set at ''0'', the coincidence is obtained with control on a fluorescent screen between two beams to perform an interlace display. Thus it is possible to avoid the deterioration of vertical image resolution at the area where the vertical correlation is weak.

摘要： PROBLEM TO BE SOLVED: To provide an image adjustment device, an image adjustment system and an image adjustment method which, even when a chromatic aberration may occur, can correct the positional deviation of a projected image with high accuracy.SOLUTION: The image adjustment device comprises an acquisition unit, a detection unit, and a correction unit. The acquisition unit acquires a reference photograph image obtained from a reference pattern image as it is photographed by an image pickup apparatus. The reference pattern image is an image having a composite color of different colors which is projected by any one of a plurality of projectors as a composite image of pattern images having colors differing from each other which may be projected separately per projector by the plurality of projectors. On the basis of the photograph image, the detection unit detects the positional deviation of chromatic aberration which is the positional deviation of those pattern images corresponding to a chromatic aberration arising from the image pickup apparatus. By using data on the positional deviation of chromatic aberration, the correction unit corrects the positional deviation of pattern images projected separately per projector.

摘要： PROBLEM TO BE SOLVED: To provide a projection system able to use a capture camera that does not require high resolution and able to highly accurately adjust the alignment of superposed images by simple signal processing.SOLUTION: A photographing device photographs a range where projection images are superposed and projected. Two photographing devises are provided, one of which photographs the left lower corner of the superposed image and the other photographs the right lower corner. Each photographing range includes test patterns displayed on two corresponding images. The control device determines adjustment information from the amount of displacement between the test patterns. Based on adjustment information, the control device instructs a projector to adjust the zooming position of a projection lens. After an amount of zoom is adjusted, a control device instructs the projector to adjust a difference between projecting positions (the adjustment of the horizontal position of a projection image and the adjustment of the vertical position of the projection image).

摘要： PROBLEM TO BE SOLVED: To make it possible to reduce flickers when a 3D image is displayed by one liquid crystal projector. SOLUTION: A video image L for a left eye and a video image R for a right eye are input in a cycle of 24 Hz to the liquid crystal projector. First, a panel driving unit of the liquid crystal projector normally rotates applied voltage to the liquid crystal and writes the image L 1 in the liquid crystal panel, and then it normally rotates the applied voltage to the liquid crystal and writes the image R 1 in the liquid crystal panel in the liquid crystal as shown in Fig.5A. Succeedingly, the panel driving unit inversely rotates the applied voltage to the liquid crystal and writes the image L 1 in the liquid crystal panel, and then it inversely rotates the applied voltage to the liquid crystal and writes in the image R 1 in the liquid crystal panel.

摘要： PROBLEM TO BE SOLVED: To establish a V shift method for achieving high reliability, high-speed response, and cost reduction. SOLUTION: An offset adding part 71 gives an offset value to each write-in line address of frame memories 12-LU, 12-LD, 12-RD, 12-RU as an initial value, thereafter, sequentially gives them an incremented value one by one as a write-in line address value, resets them to zero when they become an enable line last value, and then sequentially gives them an incremented value one by one until reaching the offset value again. A vertical changeover controller 72 controls changeover between changeover parts 62-L, 62-R when the write-in line address value becomes the offset value. This invention is applicable to a projector.
