Abstract:
The present invention discloses a capsule endoscope image display controller (26) including: an image-to-image similarity calculating unit (36) that calculates, for each image included in an image sequence captured by a capsule endoscope which moves within the digestive organs, a similarity between the image and its temporally consecutive image; an amount-of-movement calculating unit (47) that calculates, for each image included in the image sequence, an amount of movement of a feature area included in the image; a video state classifying unit (41) that classifies, for each image included in the image sequence, a video state of the image into one of the following states, based on the video state, the similarity, and the amount of movement of the image: (a) “stationary state” indicating that the capsule endoscope is stationary, (b) “digestive organs deformation state” indicating that the digestive organs are deformed, and (c) “capsule moving state” indicating that the capsule endoscope is moving, based on the similarity and the amount of movement of the image; a rendering duration determining unit (42) that determines, for each image included in the image sequence, a rendering duration between the image and its temporally consecutive image; and a display controlling unit (44) that sequentially displays, on a screen, the images included in the image sequence with the determined rendering durations.
Abstract:
An endoscope that is free from a dead area and capable of preventing the physician from overlooking any nidus is an endoscope for taking the inside of digestive organs, and the endoscope is provided with an omnidirectional camera (32), a light (34), a forceps (36) and a rinse water injection port (38) at the tip (24). The omnidirectional camera (32) is a device for taking the inside of digestive organs, and is able to take 360-degree images of its surroundings. A probe-type endoscope (20) is provided with a receiver (26) composed of orthogonal coils, and the receiver (26) is used for estimating the position and attitude of the probe-type endoscope (20). An image taken by the omnidirectional camera (32) is presented on a display unit (28) of an image processing device (22) connected to the probe-type endoscope (20). In the image processing device, a video mosaicking process is performed on a plurality of images obtained by the omnidirectional camera (32) to generate a panoramic image of the inside of a digestive organ.

Abstract:
Provided are an image processing device, an image processing method, and a program which are capable of high density restoration and which are also strong to image processing. An image processing device mainly consists of a projector serving as a projection means, a camera as a photographing means, and an image processing means consisting of, for example, a personal computer. The image processing means acquires the intersection point between patterns from a photographed image and calculates a first solution including degree of freedom by using the constraint condition of a first tentative plane and a second tentative plane including the intersection point and the constraint condition obtained from the positional relationship between the projector and the camera. The degree of freedom is cancelled by primary search, thereby restoring a three-dimensional shape.

Abstract:
To enable an image with no blind spot area to be obtained while ensuring a wide field of view, an omnidirectional imaging system includes: a primary mirror (101) including a hyperbolic mirror; a plurality of secondary mirrors (102) arranged around the primary mirror and each including a hyperbolic mirror; and a camera (104) that captures an image reflected by the primary mirror and images reflected by the plurality of secondary mirrors. A hyperboloid of the primary mirror and hyperboloids of the plurality of secondary mirrors have a substantially coincident outer focal point, and the camera (104) is placed so that a viewpoint of the camera substantially coincides with the outer focal point of the hyperboloid of the primary mirror (101) and the hyperboloids of the plurality of secondary mirrors (102), the viewpoint of the camera being an entrance pupil position of a lens attached to the camera (104).
