    Abstract: An additional motion is introduced into a scanning operation. This additional motion is in addition to the motion that is inherent in any document scanning operation. For example, in a flatbed scanner a linear array of scanning devices is positioned across the document in a first or nullxnull direction and this array is moved across the document in a perpendicular or nullynull direction. In a flatbed scanner the position of the scanning devices are fixed in the nullxnull direction. In a drum scanner a light beam moves across the document in an nullxnull direction and the document is moved in the nullynull direction. The light reflected from the document is directed to a fixed photoreceptor. With the present invention an additional vibratory motion is introduced into the scanning process. With a flatbed scanner the array of detector devices is moved or vibrated. The vibratory motion can for example be in the nullxnull direction. With a drum scanner the photoreceptor is moved or vibrated. For example the photodetector can be moved or vibrated in the nullxnull direction. The amount and direction of the vibratory movement can vary up to about one half the distance between units in the scanner's resolution (i.e. one half a pixel). If one is trying to eliminate Moirnull patterns the vibratory movement can be a pseudo random series of movements. If one is trying to introduce a special pattern into the document or to otherwise create special effects, various other type of motion can be used. Movement of the CCD array in a flatbed scanner or movement of the photoreceptor in a drum scanner can be done by a simple piezo electric transducer or by a simple mechanical cam.

    Abstract: An electronic still camera with a printer includes a vibration detector and a system controller. The vibration detector detects vibration relative to a moving direction of an exposure head of the printer. When the vibration detector detects the vibration exceeding a prescribed level, the system controller interrupts a printing operation of the printer. After that, when the vibration detector detects the vibration falling below the prescribed level, the system controller resumes the printing operation. The exposure head is adapted to be moved, performing the printing operation one line by one line. Until the printing operation for one line is completed, the system controller suspends to interrupt the printing operation.

    Abstract: An original image reading device having a plurality of light receiving elements for receiving light reflected from an original document, which are formed on a substrate, and for outputing image data signals. Two light receiving elements arrays are formed on a transparent substrate in association with two optical systems. The first light receiving elements array receives light coming through the upper surface of the transparent substrate. The second light receiving elements array receives light coming through the lower surface of the transparent substrate. With such a construction, the image at a location on an original document can be read with the two optical systems. Further, the construction can realize color original image reading device, high resolution, and different focal depths.

    Abstract: A method for resolution conversion by microaddressing an image transition in a printer includes steps of writing a print bit at zero intensity when a current image bit is in a second state and a displacement distance is greater than or equal to one-half of a pitch distance; writing the print bit at maximum intensity when the current bit is in a first state and the displacement distance is greater than or equal to one-half of the pitch distance; and writing the print bit at less than maximum intensity when the current image bit is in the first state and the displacement distance is less than one-half of the pitch distance, the step of writing the bit bit at less than maximum intensity including a step of intensity modulating a writing device based on a function proportional to a sum of the displacement distance plus one-half of the pitch distance. A print intensity controller to generate intensity data includes a modulo counter for generating print bit position data based on an image raster width and a number of intensity steps; and a memory for producing the intensity data based on the number of intensity steps, the print bit position data, a current image bit and an adjacent image bit.

    Abstract: A image input/output method for reading fine input data without increasing the amount of information and for reproducing fine image data from the input data. Data is extracted from every nth pixel in a line of pixels. The extraction process is repeated for n lines of pixels while sequentially changing the phase of the pixels from which data is extracted for each of the n lines. A single data line is formed by combining the pixel data extracted from the n lines of pixels.

    Abstract: A method for reading optical image information using a line image sensor is disclosed which comprises the steps of reading in the optical image information at a spatial frequency in the reading in the sub-scanning direction adapted to be higher than the spatial frequency in the reading in the main scanning direction and converting the read optical image information into an electric signal and outputting the electric signal to the outside. Also disclosed is an apparatus for reading optical image information according to the above method, and which comprises feed means for feeding a medium with the optical image information represented thereon in the sub-scanning direction so that the line image sensor may read the optical image information in the sub-scanning direction, control means for controlling the feed means so that the spatial frequency in the reading in the sub-scanning direction may become higher than the spatial frequency in the reading in the main scanning direction, and line density conversion means for converting an electric signal output from the line image sensor upon its reading the optical image information so that the line density in the sub-scanning direction and the line density in the main scanning direction may concur.
