    Abstract: An additional motion is introduced into a scanning operation in addition to the motion inherent in the operation. In a flatbed scanner a linear sensor array is fixedly positioned across the document in an "x" direction and is moved across the document in a perpendicular or "y" direction. In a drum scanner a light beam moves across the document in the "x" direction and the document is moved in the "y" direction. Light reflected from the document is directed to a fixed photoreceptor. With the present invention, the sensor array (14), or the photoreceptor, is moved or vibrated in the "x" direction by a simple piezo electric transducer (15) or by a simple mechanical cam. To eliminate Moire patterns the vibratory movement is a pseudo random series of movements. To introduce a special pattern into the document or to otherwise create special effects, various other types of motion can be used.

    Abstract: Methods and systems are disclosed for damping unwanted vibrations or ringing of a lens in an imaging device. For example, one method includes determining a target distance to move a lens, and dividing the target distance into multiple steps having at least a first step and a subsequent step, moving the lens, via an actuator, by the first step, thereby causing a first vibration, retrieving a damping parameter indicative of a time delay, the damping parameter being based on at least one characteristic of the actuator and the number of steps, and repeating said moving the lens at least one subsequent step after delaying the subsequent step by one of the damping parameters, each moving the lens a subsequent step causing a subsequent vibration, and the damping parameters affecting the vibration such that the first and subsequent vibrations at least in part modify each other to lower overall vibration.

    Abstract: Holographic/diffraction grating effects produced on the surface of thermal dye transfer prints due to the surface distortion caused by laser heating are prevented by disrupting the regular grid pattern in a random manner. By causing such disruption over only part of the area of the image and by suitably arranging the non-disrupted areas, an identifiable pattern can be achieved.
