  • Patent number: 6697526
    Abstract: An image compression and expansion apparatus obtains an average value of a single block (8×8 pixels) in a first matrix (64×64 pixels) of the original image data, to generate reduced image data of a second matrix (8×8 pixels). A sub-matrix, which is displaced from the second matrix by a predetermined amount, is obtained in such a manner that a pixel of the second matrix is contained in the sub-matrix. 8×8 pixels of the sub-matrix are subjected to a two dimensional discrete cosine transformation, to obtain reduced DCT coefficient data. The reduced DCT coefficient data is subjected to an expanded inverse discrete cosine transformation to obtain expanded image data of a matrix (m×n pixels). The displacement direction and the displacement amount of the sub-matrix relative to the second matrix, and the values of “m” and “an” are selected in such a manner that the expanded image data becomes as close to the original image data as possible.

  • Publication number: 20030197781
    Abstract: An electronic endoscope system that shares peripheral devices, such as a TV monitor, VCR etc., among a plurality of electronic endoscopes via an electronic endoscope selector. Each of the electronic endoscopes is connected to the electronic endoscope selector and the electronic endoscope selector selectively switches between video signals of the electronic endoscopes and feeds them to the TV monitor. Further the electronic endoscope selector comprises image memories and is able to store an image captured by the electronic endoscopes. A stored image may be comparatively displayed on the screen of the TV monitor with the live video being captured by the selected endoscope units. Further, the comparative display is controlled by control buttons on the electronic endoscope. The electronic endoscope selector also comprises a memory for storing image parameters for each electronic endoscope, and adjusts images on the screen by utilizing the parameter for each electronic endoscope.

  • Patent number: 6628457
    Abstract: Angular speed sensors and acceleration sensors are built into the casing of a video-type stereoscopic microscope. The angle of rotation of the stereoscopic microscope detected by the angular speed sensors and the amount of shift of the stereoscopic microscope detected by the acceleration sensors are input to a microscope control unit. This microscope control unit controls a vibration compensator based on the result of the detection. The vibration compensator shifts a lens within a plane orthogonal to its the optical axis so that object light from a field is deflected to a direction parallel to the optical axes of individual zoom optical systems. The vertical width AV of the field and the working distance L of this video microscope satisfy the following inequality: 1/AV>1/(11.46+0.011×L).

  • Publication number: 20030156334
    Abstract: A single-element objective lens for an optical pick-up directs an incident light beam to a data recording surface of an optical disc through a cover layer to form a beam spot thereon. A numerical aperture of the objective lens is 0.7 or more. The objective lens is configured to compensate for coma such that a characteristic of a change of spherical aberration due to a degree of divergence/convergence of the incident beam is comparable with respect to a characteristic of a change of spherical aberration due to variation of the cover layer so that the change of spherical aberration due to variation of the cover layer can be cancelled by the change of spherical aberration due to a degree of divergence/convergence of the incident beam.

  • Publication number: 20030152014
    Abstract: A single-element objective lens is employed in an optical pick-up. The objective lens directs an incident light beam to a data recording surface of an optical disc through a cover layer to form a beam spot thereon. A numerical aperture of the objective lens is 0.7 or more. The objective lens is configured such that a characteristic of aberration which is generated due to decentering of surfaces of the objective lens is substantially comparable to a characteristic of aberration due to an inclination of an optical axis of the objective lens and an inclination of a central axis of the light beam incident on the data recording surface of the optical disc with respect to the optical disc.
