摘要： Fixed pattern noise of an analog memory is reduced. Transfer paths of an address selection signal (SL) between an address generation unit (10) and respective storage elements (21) for storing an analog signal are constructed to have a substantially uniform electric characteristic in driving the storage elements (21) by the address selection signal (SL) to such an extent that the output signal of the analog memory is free from fixed pattern noise. A buffer unit (50) for temporarily storing and outputting the address selection signal is provided between the address generation unit (10) and the respective storage elements (21), and the buffer unit (50) is constructed to have an output characteristic substantially uniform between the storage elements (21). Also, lines between the buffer unit (50) and the storage elements (21) are constructed to have substantially the same electric characteristic. In this manner, charge feed through noise of the respective storage elements (21) are made substantially uniform, resulting in suppressing the fixed pattern noise.

摘要： To adjust image distortion such as geometric distortion or misconvergence in an image displayed by a projection type color display apparatus, absolute screen coordinates are assigned to each of plural photodetector elements disposed in the display screen periphery, a test pattern for image distortion adjustment is detected, and the resulting output ratios of the photodetector elements are weighted by the screen coordinate values to achieve high precision test pattern position detection. High speed, high precision image distortion adjustment is thus achieved, and changes over time in image distortion resulting from temperature-related drift and other factors can be constantly or occasionally corrected while displaying a normal video image to the screen.

摘要： A convergence correction circuit, for a cathode ray tube (80, 81, 82) projecting images having keystone, differential sinusoidal and differential right-edge curl distortions, comprises generators (10; 120; R102, R103, R104, CR100, Q100) for horizontal-rate, generally sinusoidal, horizontal-rate sawtooth and horizontal-rate pulse waveforms (C, M, K). A summer (45) combines the horizontal-rate waveforms into a horizontal-rate composite waveform (L). A multiplier (60) and an amplifier (71) generate as an output signal (II) a product of the horizontal-rate composite waveform (L) and a vertical-rate sawtooth waveform (F). A convergence correction coil (88) is coupled for receiving the output signal (II) and generating a dynamic magnetic field correcting the keystone, differential sinusoidal and differential right-edge curl distortions.
