摘要： A photographing method and apparatus for photographing a fluorescent image, composed of fluorescent light emitted by a living tissue that has been illuminated by a stimulating light, as an image having a higher S/N ratio. Fluorescent light emitted by a living tissue that has been illuminated by a stimulating light emitted from a light source and propagated along an endoscope enters an image fiber. The fluorescent light entering the image fiber is propagated along the image fiber to the output face of the image fiber and focused on the light-receiving zone of a photographing element, under photographing conditions set so that the relation between the pixels of aforementioned output face, upon which the fluorescent image is formed, to the pixels receiving the light of the fluorescent image within aforementioned light-receiving zone satisfies the condition expressed by the formula: Nf×4>Nd.

摘要： The method involves using multiple aperture multiplexing, with display of image composite in fast sequences such that viewer does not detect changes. The method involves using a screen and an optical closure device in the beam path that can be blocked or made transparent for the segment. The observer is positioned within a defined distance and angular range with respect to the associated device. Perspective views are acquired in real time or non-real time using one or more or one moving image acquisition devices. This provides digital data sets that are converted into suitable image composites and displayed on a screen by a multiplex method. A controller opens one or more closure device apertures to display the image composite, in a sequence so fast that the observer does not detect the changes.

摘要： A focus detecting device for detecting images from different pupil areas on time-shared basis, and detecting the phase difference of the images from the different areas, thereby detecting the defocus amount, is described. The focus detecting device of this type is incapable of exact defocus amount detection, because of the influence of the relative movement between the object and the photographing optical system. The exact defocus amount can be determined by detecting images from a same pupil area on time-shared basis, determining the phase difference between such images and effecting correction corresponding to the phase difference between the images from the same pupil area.

摘要： A method is proposed for automatically obtaining depth. information from a 2-D motion image, so as to create an image for a 3-D display. Further, methods are proposed for selecting appropriate frames for the calculation of the depth information, or discontinuing the calculation, and for conducting image., processing using the depth information. Examples of various types of image processing can be listed as including the creation of a viewfinder image seen from a different point, natural scaling operations to an image area, and separation of a desired image area. First, a motion information of an object on a screen is extracted by block matching or the like. Second, the actual movement of the object in the 3-D world is calculated. Since the viewfinder image is a projection of a 3-D space, it is possible to obtain the original 3-D movement of the object, based on the movements of a plurality of representative points through an inverse transformation, the representative points being provided in the viewfinder image. Resultantly, 3-D coordinates of this object are identified, so that depth information of the object is obtained. Afterwards, a parallax is calculated based on the depth information, so as to create right and left eye images from the input viewfinder image. Alternatively, image processing, such as separation of an object having a depth within a predetermined range, is carried out based on the depth information.

摘要： A digital broadcasting system is obtained having simple facilities and circuit structure and capable of efficiently transmitting and receiving synchronized pictures and displaying them without applying a synchronizing process thereto. According to the digital broadcasting system, picture signals respectively for the light eye and the left eye obtained from two synchronously operated cameras (13a, 13b) are converted to a noninterlace frame signal (picture data) by a frame memory unit (20) of the transmitting end. The picture data is compressed and modulated, and then transmitted to a communication satellite (8) over a transmission line of one channel. A transmission signal supplied from the communication satellite (8) is demodulated and decoded, and then converted to picture signals for the right and left eyes by a frame memory unit (21) of the receiving end, and the converted signals are displayed on a stereoscopic display monitor (12) in a stereoscopic manner.

摘要： A 3D model of a scene is constructed by acquiring first images of a scene having unknown characteristics with a first camera. Corresponding second images of a another scene having known characteristics are acquired by a second camera. The first and second cameras have a fixed physical relationship to each other. Only the second images are analyzed to determine corresponding positions of the second camera while acquiring the first images. Then, the first images are assembled into the 3D model using the corresponding positions and the fixed physical relationship of the first and second camera.

摘要： The stereoscopic CG image generating apparatus and a stereoscopic TV apparatus, has a projection transformation section which, based on three-dimensional structural information describing a three-dimensional shape of an object, generates a plurality of two-dimensional projection models as viewed from a plurality of viewpoints, a distance information extraction section which generates a camera-to-object distance information used for calculations in the projection transformation section, and a camera parameter determining section which, based on the output of the distance information extraction section, the screen size of a stereoscopic image display device for displaying finally generated two-dimensional projection models, and a viewer's viewing distance, determines camera parameters so that stereoscopic CG images will be brought within the viewer's binocular fusional range. According to the thus constructed stereoscopic CG image generating apparatus and stereoscopic TV apparatus, proper camera parameters (focal length or field of view, camera spacing, and converging point) are determined based on the camera-to-object distance information, the magnitude of parallax of the generated stereoscopic CG images on the display device (or in a window on the display screen), and the viewing distance, so that easy-to-view stereoscopic CG images are automatically generated regardless of the display size, and by horizontally translating left-eye and right-eye images, binocular parallax of displayed images is automatically brought within the viewer's binocular fusional range regardless of the size of a stereoscopic display used.
