  • Patent number: 7126758
    Abstract: Disclosed is a compact zoom lens system having a image stabilizing function. This zoom lens system is provided with a plurality of lens units of which the interval between adjacent ones is changed during zooming. Shake correction is effected by a part of a lens unit of negative optical power of the plurality of lens units. Specifically, the lens unit of negative optical power is comprised of two lens components of negative optical power, and one of these two lens components is moved so as to have a component in a direction perpendicular to an optical axis to thereby change the imaging position of the zoom lens system.

  • Patent number: 7057632
    Abstract: An optical scanning apparatus includes a laser unit formed by integrating a semiconductor laser and collimator lens, an incident optical system for making a light beam emerging from the laser unit strike an optical deflector while keeping the light beam wider than the width of a deflecting surface of the optical deflector in the main scanning direction, and an imaging optical system for forming the light beam reflected/deflected by the optical deflector into an image on a scanned surface. The laser unit is shifted by a shift adjusting means in a predetermined direction with respect to the optical axis of the incident optical system so as to make an illuminance distribution of scanning lines on the scanned surface become substantially symmetrical about the scanning central axis.

  • Patent number: 6967679
    Abstract: The present invention discloses an imaging apparatus constructed as follows. The imaging apparatus picks-up a subject image formed by a imaging optical unit, and comprises an image pickup device for photoelectrically converting a subject image, a memory for storing gamma property data of the image pickup device and light quantity distribution data of incident light in accordance with pixel positions on the image pickup device; and a correcting circuit for correcting image signals outputted from each pixel of the image pickup device based on the gamma property data and light quantity distribution data that are stored in the memory. Thereby, a drop in peripheral light quantity can be electrically corrected while reflecting the gamma property of the image pickup device without an increase in noise, whereby a high-quality image accurately reproducing the actual brightness distribution in a shooting range can be obtained.

  • Patent number: 6927883
    Abstract: A high definition light-scanning optical apparatus uses an oblique incidence optical system and has a simple configuration that does not exert any adverse effect on the quality of the image formed by it as the elements of the apparatus are appropriately arranged. The light-scanning optical apparatus comprises an incidence optical system adapted to cause the light beam emitted from an incident light emitting light source including a fold mirror to strike a deflection plane of an optical deflector with a predetermined angle in the sub-scanning section and a focussing optical system for focussing the light beam reflected by the deflection plane of the optical deflector on a surface to be scanned. The focussing optical system includes an f? lens system having a spherical lens and a first cylindrical lens showing power in the main-scanning direction and a second cylindrical lens showing power in the sub-scanning direction.

  • Patent number: 6496310
    Abstract: An optical system includes a diffractive optical element in which a phase given to incident light from an optical axis toward the peripheral part in the radial direction is not reversed in an effective area and an absolute value of optical power on the optical axis is made minimum. In the optical system, chromatic aberration of magnification of a high order is satisfactorily corrected and flare caused by additional diffraction light (unnecessary diffraction light) is suppressed to as minimum as possible while maintaining a high imaging performance up to peripheral part of a field angle.

  • Patent number: 6459470
    Abstract: An image printer for printing images with less cross-talk between images and less image flickering is provided. A plurality of images are interleft in one or a plurality of line units and a lenticular lens is used to make it possible for each individual pixel to be distinguished. The difference in brightness between an attentional pixel and the surrounding pixels that surround this attentional pixel is taken, and a correlation value is produced, the correlation value being reduced if the difference is large and increased if the difference is small. The image printer is equipped with a pixel shape controller that makes the printed pixels smaller in a region where the correlation value is low, and makes the printed pixels larger in a region where the correlation value is high.
