  • Patent number: 8466956
    Abstract: A scanning endoscope processor, comprising a photoelectric converter and a controller, is provided. The scanning endoscope processor controls a scanning endoscope having first and second transmitters and an actuator. The photoelectric converter receives light transmitted from the second transmitter and generates a pixel signal according to the amount of light received. The second transmitter transmits reflected light and/or fluorescence from a point within an observation area illuminated by the light emitted from a first emission end. The first transmitter emits the light as a beam from the first emission end. The actuator moves the first emission end along a spiral course. The controller adjusts at least one of a first angular velocity and a generation cycle so that the product of the first angular velocity, the generation cycle, and a first distance is within a predetermined range.

  • Patent number: 8427746
    Abstract: The present invention discloses a stereoscopic image display system and a method of controlling the same. An eye tracking module locates current 3D spatial positions of the viewer's eyes, and generates the information of both left and right eyes' current 3D spatial positions. A control module controls a display device that can alter the direction of the light outputted, and outputs images on the display device in time multiplex mode. The light containing the left eye image is outputted to the position of left eye instead of right eye at one time point, and the light containing the right eye image is outputted to the position of right eye instead of left eye at another time point, so that a stereoscopic image is perceived according to the parallax theory. The present invention enlarges the visual range of stereoscopic image and achieves a better stereoscopic image visual experience for viewers.

The disc consists of transparent glass sectors and filter sectors. Each time the general illumination light passes through the filter sectors, the illuminator emits specific illumination light having different spectral characteristics from those of the general illumination light, so a CCD outputs two kinds of image signals under the general illumination light and the specific illumination light. A spectral image producer produces a spectral image of arbitrary wavelength bands from the two kinds of image signals, whereas a general image producer produces a general image from those image signals captured under the general illumination light.

The processor includes a gate section opened or closed to input of the reference clock to the phase comparator, an operation control signal generation section which generates an operation control signal for setting the phase-locked loop circuit in a closed loop operable state during intermittent periods, and a sync timing setting section which synchronizes a timing of starting the generation of the operation control signal with a timing of input of the variable clock to the phase comparator at least within a predetermined time period shorter than the cycle of the variable clock.

  • Publication number: 20120206571
    Abstract: In one embodiment, an element 106 transform, with a voltage, non-polarized light into plane polarized light with an arbitrary plane of polarization. A synchronizer 112 gives the plane of polarization control element 106 an instruction to rotate the plane of polarization, thereby getting the plane of polarization of the illumination rotated and casting that polarized light toward the object. At the same time, the synchronizer 112 sends a shooting start signal to an image sensor 110, thereby getting video. The synchronizer 112 performs these processing steps multiple times. A captured video signal is sent to an image processing processor 108, where LL, RR and CC images are separately generated as images of light rays that have passed through left and right polarizing areas and the central non-polarizing area and left and right parallax signals are generated and sent to a 3D display section 122.

  • Patent number: 8243122
    Abstract: The present invention provides a method of generating a virtual viewpoint video image when the virtual viewpoint position is not located on a plane where a camera is disposed. In an environment in which a plurality of cameras having a horizontal optical axis are disposed in a real zone (for example, on the circumference) which surrounds an object, a video image of an arbitrary viewpoint on the circumference is generated. Further, by synthesizing video images photographed by a camera, a free viewpoint video image is generated from a virtual viewpoint (viewpoint from a high or low position) where no camera is placed. According to a method of achieving this, a travel distance of a display position is calculated by the local region synthesizing portion and this travel distance is reflected to the free viewpoint video image of a local region.

  • Patent number: 8228368
    Abstract: An illumination channel, a stereoscopic optical channel and another optical channel are held and positioned by a robotic surgical system. A first capture unit captures a stereoscopic visible image from the first light from the stereoscopic optical channel while a second capture unit captures a fluorescence image from the second light from the other optical channel. An intelligent image processing system receives the captured stereoscopic visible image and the captured fluorescence image and generates a stereoscopic pair of fluorescence images. An augmented stereoscopic display system outputs a real-time stereoscopic image comprising a three-dimensional presentation of a blend of the stereoscopic visible image and the stereoscopic pair of fluorescence images.
