An endoscope apparatus includes an endoscope that includes an imaging section that captures an object, and an illumination section that includes an irradiation port that illuminates the object, the imaging section and the illumination section being provided in an end section of the endoscope, a distance information acquisition section that acquires distance information about a distance from the end section of the endoscope to the object, a light distribution pattern determination section that determines a light distribution pattern of illumination light applied from the illumination section based on the acquired distance information, and a gradation correction section that performs a gradation correction process on a captured image acquired by the imaging section.

There is provided an endoscope apparatus which enables to observe a three-dimensional image which is easy to view even in close observation.

An endoscope apparatus, comprises: optical systems which form images for a left-eye and a right-eye respectively; an image pickup element which captures the two images and generates pictorial images for the left eye and the right eye; and at least one image processing unit which carries out processing of a pictorial image signal from the image pickup element and creates a stereoscopic image that can be displayed on a monitor, wherein the endoscope apparatus satisfies the following conditional expression (1)

0.3<CP×(1+Dt1)<7, and CP≦10   (1) where, CP denotes a distance (mm) from a surface nearest to object of the optical system up to an object, when an amount of left and right shift of the left-eye pictorial image and the right-eye pictorial image becomes 0, at a center of a monitor screen, and Dt1 denotes a distortion in length at the maximum image height.

Various aspects of a system and method to process an image for generation of a three-dimensional (3D) view of an anatomical portion are disclosed herein. The system includes an image-processing device configured to receive a plurality of two-dimensional (2D) images associated of an anatomical portion, each with a first field-of-view (FOV) value. A first 3D view of the anatomical portion with a second FOV value, is generated from a 3D reconstruction of the anatomical portion. The 3D reconstruction is obtained by use of a set of 2D image frames selected from the received plurality of 2D images. The second FOV value is greater than the first FOV value of each of the plurality of 2D images of the anatomical portion. A second 3D view is generated, based on the alignment of the generated first 3D view with 3D data associated with a pre-operative state of the anatomical portion.

An imaging system includes: an optical unit; an imaging device configured to capture an optical image imaged by the optical unit; and a processing device configured to perform image processing on image data transmitted from the imaging device. The processing device includes: a data acquisition unit configured to acquire view angle correction data from a first storage unit; and a correction unit configured to correct at least one of first image data and second image data based on the view angle correction data acquired by the data acquisition unit such that a view angle of a first image corresponding to the first image data and a view angle of a second image corresponding to the second image data match each other, and a size of the first image and a size of the second image match each other.

A depiction system for generating a real time correlated depiction of movements of a surgical tool for uses in minimally invasive surgery is described. In an embodiment the system includes a computer system, 3D surface data generation means and position data generation means for obtaining real time spatial position data of at least a part of the surgical tool. The 3D surface data generation means or the position data generation is adapted for providing surface position data of at least the target area. The computer system is programmed for determining depiction data representing a depiction of the real time relative spatial position(s) of the surgical tool onto at least a portion of the surface contour of the surface section of the minimally invasive surgery cavity.

An endoscope includes two or more imaging modules having a lens barrel containing an optical system, an image sensor, and a sensor holding member that relatively fixes the lens barrel and the image sensor, a sub-frame that relatively fixes each of the two or more imaging modules, and an outer shell portion that accommodates and fixes the sub-frame and the two or more imaging modules.

An endoscopic system includes a single-use portion and a multiple-use portion. The two portions can be mated and un-mated. The single-use portion includes an elongated cannula that has a bendable section near its distal end providing a “steerable” distal tip. The imaging system includes at least two separate cameras and two separate light sources. The camera and light sources are configured to simultaneously image a target object. By employing different illuminations, different filters and manipulating the spectral responses, different characteristics of the target object can be captured. According to some embodiments, a system processor can coordinate the cameras, the light sources and combine the resulting images to display to an operator an enhanced combined image the object.

An image capture device includes a plurality of stacked ceramic circuit boards, an image sensor, signal conditioning electronics, and a connector. Each ceramic circuit board is parallel and directly coupled to at least one other circuit board. The image sensor is mounted to a first ceramic circuit board. The signal conditioning electronics are mounted to one or more of the stacked ceramic circuit boards and are coupled to receive electrical signals generated by the image sensor. The image capture device is enclosed by a shaft and the stacked ceramic circuit boards are stacked along a length of the shaft. The connector is mounted to a second ceramic circuit board that is on an opposite side of the plurality of stacked ceramic circuit boards from the first ceramic circuit board. The connector is mounted to a side of the second ceramic circuit board facing away from the first ceramic circuit board.

The present invention relates to a dental tool system, comprising a detection system (101) for detecting a spatial position (103-Z) of a tooth (115) or a tooth situation and a spatial tool position (103-W) of a tool (107); and a device (105) for controlling or regulating the tool (107) on the basis of the detected tool position (103-W) in relation to the position (103-Z) of the tooth (115) or the tooth situation.

A medical system may comprise a stereo display and an input device. The medical system may also comprise a processor configured to generate a three-dimensional image of an anatomical object and cause the three-dimensional image of the anatomical object and a two-dimensional window to be displayed. The processor may also be configured to cause a position and an orientation of the two-dimensional window relative to the three-dimensional image of the anatomical object to be changed on the stereo display by manipulation of the input device. The processor may also be configured to define a cut-plane to indicate a two-dimensional slice of the three-dimensional image of the anatomical object. The processor may also be configured to cause the two-dimensional slice of the three-dimensional image of the anatomical object to be displayed. An orientation of the displayed two-dimensional slice may be different than an orientation of the cut-plane with the three-dimensional image.
