To accurately recognize observed objects. An observed-object recognition system includes an observation region estimation portion, an existence region estimation portion, and an object recognition portion. The observation region estimation portion estimates an observation region that is relatively highly likely to be an observation point in at least one first-person image in a first-person video (a video based on the first-person perspective). Based on the observation region, the existence region estimation portion estimates an existence region that belongs to the first-person image and causes an observed object to exist. The object recognition portion recognizes an object in the estimated existence region of the first-person image.

Observed-object recognition system and method

The present invention is provided to notify a person who makes a movement of a part to be improved in the movement. A movement evaluation system includes: a proficiency degree estimating unit generating a proficiency degree score on the basis of movement data obtained by detecting a movement of a user; an improvement point extracting unit specifying a part of the movement of the user as an improvement point on the basis of the movement data; and an information generating unit generating suggestion information to be presented to the user, on the basis of the improvement point.

The present invention discloses a posture estimation system including a range image camera for acquiring and outputting range image and an attitude estimation device connected via the network to the range image camera. The range image camera includes a range image sensor, a range image generator that extracts a region including foreground pixels from the input range image acquired from the range image sensor and generates a range image including the extracted area, a first posture estimator that estimates a first joint position from the range image, and a first communicator that transmits the range image and the estimated first joint position. The posture estimating device includes a second communicator that receives the range image from the range image camera and the first joint position, a range image receiver that receives the range image via the second communicator, a posture estimator that estimates recognizes a second joint position different from the first joint position based on the range image received by the range image receiving unit, and generates estimated posture information based on the first joint position and the second joint position, and an outputter that outputs the generated estimated attitude information, wherein the first communicator sends a range image used for extracting the second joint position to the network.

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.

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.

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 Dand D, 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.

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.

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.
