摘要： This invention provides a cut-off adjusting apparatus in which any signal source for detecting cathode current is not required, the cost can be reduced, the cathode current can be detected with high precision, and the correction corresponding to time-variation can be performed with high precision. There is provided a controller in which when an enforced adjusting mode is set, during a vertical period a control signal is output to a video amplifier to output such a signal that no video signal is contained in the output and the pedestal level is black level irrespective of input of a video signal, an averaged cathode current at this time is detected, subsequently, a control signal is output to the video amplifier to output such a signal that the brightness level is set gray, an averaged cathode current at this time is detected, the differential value therebetween is determined, the measurement value thereof and an initial set value are compared with each other, and a control signal is output to a third terminal of the cut-off control amplifier so that the measurement value is equal to the initial set value.

摘要： Method and apparatus are provided for seamless integration of multiple video projectors (100a, 100b). Edge blending and projection artifacts in dark or black image regions caused by residual grays from non-perfect projector black levels are reduced. Overlapped (102a, 102b) and non-overlapped areas (104a, 104b) are defined and then the minimum black level (208) of the video signal in non-overlapped areas is boosted without affecting the bright portion of the video signal in order to create uniform black level. The bright portion of the image is then smoothed in the overlapped area with seamless edge blending techniques. The resultant projected image may be passed through a neutral density filter (562). The image may also pass through a physical mask (712a, 712b).

摘要： An apparatus comprises a source of a first signal synchronized to deflection, the first signal including a first portion representative of a retrace interval, means coupled to a first video signal and responsive to a second signal representative of the retrace interval for generating a second video signal having a blanking interval, and means responsive to a third signal representative of the blanking interval and to the first signal for generating the second signal so as to control the phase of the blanking interval relative to the retrace interval.

摘要： The invention relates to a method and circuit for controlling the operating point of a cathode ray tube (3). A video signal (1) can be transmitted to both the tube (3) as well as to a cathode ray tube model (2). The model (2) emulates a beam current from said video signal (2). A characteristic quantity provided for resetting the operating point is determined from the emulated beam current and from a measured beam current. The invention is used in imaging technology.
