摘要:
A method and apparatus for printing on to a photosensitive material. The apparatus includes a light source for producing light composed of at least two colors, a collimator for collimating the light produced by the light source so as form a beam of light, a modulator for modulating the beam of light in accordance with one of the predetermined color components, a filter for filtering out the color component which has been modulated, and a beam directing device for directing the modulated colored filter beam of light, onto a photosensitive material.
摘要:
An electronic adjustment system is disclosed that includes an operator interface for entering selected digital parameter values into a non-volatile memory. A processing unit provides the digital parameter values stored in the non-volatile memory to a video circuit. The digital parameter values control certain operational parameters of the video circuit and can be easily changed by the operator to adjust the operational parameters of the video circuit without the need for adjustment switches or potentiometers.
