Abstract: A surgical stereoscopic observation apparatus has a pair of main optical paths A and a pair of secondary optical paths B, an aligning direction of the paths B differing by 90 degrees from that of the paths A. The main and secondary optical paths involve imaging elements D1 and D2, respectively. This apparatus is able to provide not only electronic images oriented for a main operator and an assistant positioned opposite to the main operator but also electronic images orientated for an assistant positioned on the left or right side of the main operator, thereby allowing the main operator and assistants to cooperatively conduct an operation.

Abstract: A surgical stereoscopic observation apparatus defines main optical paths and secondary optical paths that are branched from the main optical paths A and run to a pair of fluorescence imaging elements. The apparatus picks up both visible-light images and fluorescence images, displays the images on an electronic image display unit, and allows an observer to stereoscopically observe the displayed images.

Abstract: A surgical microscope apparatus has a discharge pump unit that is attached to a rear arm of a parallel linkage mechanism and is exposed to an outside. The discharge pump unit, therefore, is easy to remove from a stand body when repairing or maintaining the same. Namely, the repair or maintenance of the discharge pump unit is easy to carry out. The discharge pump unit is not present inside a horizontal arm, and therefore, never increases the weight of the horizontal arm.

Abstract: A stand apparatus for a surgical microscope includes a stand body and a parallel linkage. The parallel linkage is rotatably attached to the stand body by attaching a lower-end joint thereof instead of a vertical intermediate part thereof to the stand body. When the parallel linkage is tilted frontward, no part of the parallel linkage protrudes rearward. Weight balance of the frontward tilted parallel linkage is maintained by, instead of a counterweight, a compression spring arranged along a rear sub-arm.

Abstract: A surgical microscope has an upper face provided with a light beam outlet. An assistant scope is mounted on the light beam outlet, and is rotatable in a horizontal plane so as to direct in any direction in the plane.

Abstract: A surgical microscope system includes a surgical microscope. In the surgical microscope, variable power optical systems are arranged horizontally to fold optical paths, thereby reducing a vertical size between eyepieces of the surgical microscope and a lower end of the same and expanding a working space under the surgical microscope. A camera is attached to an upper part of the surgical microscope to free a side face of the surgical microscope so that an accessory such as a fluorescent camera is attached to the side face.

Abstract: A medical stand apparatus includes a cylindrical lower arm that accommodates an upper arm divided into sections, so that only the lower arm is visible from the outside and so that a drape can tightly be fastened to the lower arm. The upper arm sections are connected to each other through a shaft that is guided along an arc groove of a bracket. This configuration is beneficial to reduce a diameter of the lower arm when the upper and lower arms are curved.

Abstract: It is possible to consider an image as a composite wave that is the result of layering waves having differing periods and amplitudes. An image captured via a lens having a water droplet attached thereto has a higher occurrence of changes such as image blur than an image that does not have a water droplet attached thereto, which means that this type of change in an image results in changes in the composite wave thereof as well. Provided is a lens dirtiness detection device that suitably determines whether a lens is dirty without being affected by a background image by: focusing on the occurrence of large changes in the composite wave of an image that accompany an increase in the dirtiness of a camera lens; extracting each of the image frequency components that constitute the composite wave; and analyzing changes in the magnitude relation between the frequency components.

Abstract: An approaching-object detection system detects an approaching object based on images captured by an imaging device. The approaching-object detection system comprises an extraction unit, a distortion correction unit, an object detection unit, and an approaching-object classification unit. The extraction unit extracts a partial image of one far side and a partial image of the other far side from each of the images. The distortion correction unit corrects distortion of the partial images. The object detection unit detects an object from the corrected partial images through pattern matching with reference to preinstalled image information on the object. The approaching-object classification unit classifies the detection result of the object detection unit as an approaching object or not.

Abstract: An eyepiece structure for a surgical microscope includes an inner barrel, an intermediate barrel, and outer barrels. When the outer barrels are rotated, a protrusion of the inner barrel is guided along a spiral groove of the outer barrel and is moved back and forth along an optical axis. The protrusion is guided through a straight hole of the intermediate barrel that is not rotatable, and therefore, the inner barrel moves along the optical axis without rotating around the optical axis. An astigmatic lens is added to the inner barrel that is nonrotatable, to enable a surgeon suffering from astigmatism to conduct a surgical operation without glasses.

Abstract: A surgical microscope system includes a camera that is rotatable around a first rotation axis and a second rotation axis, the rotation axes being orthogonal to each other, so that a photographing direction of the camera is changeable at a given position. The first rotation axis is inclined with respect to a vertical axis, and therefore, a lower end of a first member is able to be set at a height that does not interfere with the photographing direction when the camera is horizontally oriented.

Abstract: An object detection apparatus receives an input of a compressed image stream, extracts, from a block included in the input compressed image stream, predetermined compression encoded information representing a feature of a compressed image, and determines, based on the extracted predetermined compression encoded information, whether or not the block is a candidate block including at least a part of the specific object. The object detection apparatus identifies, in a decoded image decoded from the compressed image stream, a candidate region of a predetermined size including the candidate block, calculates a predetermined feature amount from image data of the candidate region, and determines, based on the calculated predetermined feature amount, whether or not the candidate region includes at least a part of the specific object.

Abstract: An image processing device includes: an image acquisition unit that obtains a photographic image of an area outside of a vehicle captured and output by a camera; a sun decision unit that calculates a sun position which indicates, at least, a solar elevation and makes a decision as to whether or not the solar elevation is equal to or lower than a predetermined elevation; an opacity detection unit that detects clouding of a lens surface of the camera; a vehicle detection unit that detects another vehicle, different from the vehicle, based upon image information of a first image area in the photographic image; and a control unit that suspends detection of the other vehicle by the vehicle detection unit if the opacity detection unit detects opacity in, at least, the first image area and the sun decision unit decides that the solar elevation is equal to or lower than the predetermined elevation.

Abstract: A surgical stereoscopic observation apparatus includes an objective optical system having an optical axis and emits two focusing beams in parallel with the optical axis toward the objective optical system. If a focal point of the objective optical system agrees with a surgical field, the two focusing beams converge to a single spot on the surgical field, and if disagrees with the surgical field, form two spots on the surgical field. According to the state of the spots, it is possible to quickly determine with naked eye or on a monitor whether or not the focal point is on the surgical field.
