Below will be with image-forming principle and the characteristics that routine specific explanations installs the capsule endoscope of reflecting mirror additional that are designed among Fig. 2 (a).
Fig. 3 has showed the imaging process of the point of small bowel surface diverse location.With an X is example, and two light of ordering from X reflect the back on reflecting mirror is gathered by convex lens, and this process can be decomposed into two steps, the first, and the relative reflecting mirror of X point images in X ' point; The second, virtual X ' point is imaged on X on the imageing sensor through lens focus " point.And be example with another Y, two light of ordering from Y, one is stopped that by opaque capsule housing another has been folded to the direction away from camera lens and imageing sensor after mirror reflects, thereby can not obtain the picture point that Y is ordered on imageing sensor.O point between X point and the Y point is a particular point, its correspondence be the center O of imageing sensor " point.The point (as X) on O point right side can be imaged onto the lower semisection of imageing sensor on intestinal wall, and the point (as Y) in O point left side then can not be by imaging.In fact,, can control the specular cross section of reflecting mirror by the scope of blocking of design capsule housing opaque section, make every bit on the intestinal wall all can be one by one corresponding on the imageing sensor a bit, obtain clear non-overlapping image thus.
Fig. 4 has showed imaging scope of the present invention (visual field).Explain as the preceding paragraph, one section (O-E) on a certain longitudinal section of small bowel can be by imaging on the imageing sensor one section (O "-E ") behind the reflecting mirror conversion direction, wherein, the O point aligns O with the tip of coniform reflecting mirror " point be the center of imageing sensor; And E point position is by the camera lens size, and camera lens is to the distance of reflecting mirror, and the decision of reflecting mirror size, E " point on the imageing sensor a bit, its particular location by E point position and imageing sensor and camera lens apart from determining.Adjust the camera lens size by design, imageing sensor is to the distance of camera lens, and camera lens is to the distance of reflecting mirror, and the size of reflecting mirror, and the position of transparent spherical shell and capsule housing can obtain the closely small bowel imaging of ideal omnirange.
Fig. 5 has showed the parameter of example of the present invention (a).The camera lens radius R
Lens, the imageing sensor radius R
CCD, imageing sensor to camera lens apart from S1, camera lens to reflecting mirror apart from l, 45 the degree coniform reflecting mirror radius R
m, and the capsule radius R
WCE, the small intestinal radius R.The usable reflection zone h of reflecting mirror is by the size decision of capsule housing and transparent spherical shell.As preceding two sections explanation, the reflecting mirror imaging at first relatively of the point (O-E) on the small bowel obtains one group of picture point on E '-O ' section, and these points (source point of being regarded lens imaging) are gathered via camera lens more then, are imaged onto O on imageing sensor "-E " point.Therefore, in the second step convex lens imaging process, all source points equate that to the distance of camera lens therefore taking a picture can not occur because of losing the burnt fuzzy and distortion that produces.
Fig. 6 has showed in the capsule endoscope imaging on the imageing sensor corresponding relation of source point on the pixel and small bowel.Wherein Fig. 6 (a) is a conventional capsules endoscope, and Fig. 6 (b) is a schematic diagram of the present invention.The conventional capsules endoscope shown in the analysis chart 6 (a) at first: suppose that P ' point and Q ' point are 2 adjacent points on the imageing sensor, their pixel number is respectively I and I-1.d
IBe the distance between source point P point on the small bowel of their correspondences and the Q point, and d
pAnd d
qBe respectively the position of P point and the relative initial point O of Q point.Hence one can see that:
Because
K is a pixel number; So
The present invention shown in the analysis chart 6 (b) then---the capsule endoscope of band reflecting mirror commutation.P " point and Q " point is 2 adjacent points on the imageing sensor, their pixel number is respectively I and I-1.Source point P ' the point of their correspondences is d with the position of the relative initial point O of Q ' point
pAnd d
q, the distance between them be between the source point on the small bowel apart from d
IIn like manner as can be known:
Because
K is a pixel number; So
Observe above two formula, can see in conventional capsules endoscope, the source point of neighbor pixel correspondence distance is relevant with the pixel numbering, and pixel is far away more apart from the edge, and the distance between the corresponding source point is just far away more, and the entire image distortion is serious; And in the design, the source point of neighbor pixel correspondence distance is irrelevant with the pixel numbering, is a constant, so the position of pixel can not influence the expression of pixel content, thereby has reduced distortion greatly.
In sum, it is little to the invention solves conventional wireless capsule endoscope field range, brightness is low, distortion seriously causes occurring in the clinical diagnosis process problem that omission causes, provide a kind of and have the more wireless capsule endoscope of broad horizon than prior art, reduced the distortion that conventional art brings, enlarged the effective area of institute's images acquired, improved the brightness of image under the equal lighting condition, thereby reduced battery consumption, and, improve the using value of wireless capsule endoscope on the whole to the gastrointestinal disease diagnosis for the later image processing provides convenience.
Fig. 2 has showed two specific embodiments, adopts different reflecting mirrors to reach different purposes.Note that protection scope of the present invention is not subjected to the restriction of following embodiment.Wherein, Fig. 2 (a) adopts coniform reflecting mirror, and the commutation angle of reflecting mirror is 90 degree, so the observation scope of capsule endoscope is capsular side, and this type of reflecting mirror all can be considered to a plane mirror on each cross section, axis; And Fig. 2 (b) adopts convex reflecting mirror, and the observation scope of this type of capsule endoscope is wider, can cover very wide one section in positive side to oblique the place ahead.
