  • Patent number: 9041793
    Abstract: A method of using a scanning microscope to rapidly form a digital image of an area. The method includes performing an initial set of scans to form a guide pixel set for the area and using the guide pixel set to identify regions representing structures of interest in the area. Then, performing additional scans of the regions representing structures of interest, to gather further data to further evaluate pixels in the regions, and not scanning elsewhere in the area.

  • Publication number: 20150141753
    Abstract: An image processing apparatus according to the present disclosure includes an illuminating section which sequentially irradiates an object with first and second illuminating light beams polarized in first and second directions. First and second polarization images are generated based on signals representing light transmitted through polarizers having the polarization transmission axis in respective directions that are parallel to, and intersect with, the first direction while the object is being irradiated with the first illuminating light beam, and third and fourth polarization images are generated based on signals representing light transmitted through polarizers having the polarization transmission axis in respective directions that are parallel to, and intersect with, the second direction while the object is being irradiated with the second illuminating light beam.

  • Patent number: 9030543
    Abstract: An image with an expanded depth of field is more effectively acquired while reducing the manufacturing cost, without enlarging the apparatus. Provided is an endoscope system including: an objective optical system that is provided at an insertion portion tip and that acquires a subject image; an optical path division means for dividing the subject image into two optical images with different focuses; an imaging element that forms the two optical images with different focuses at the same time to acquire two images; an image correction means that corrects the two images acquired by the imaging element so that differences other than the focuses become substantially the same; and an image combination processing unit that selects an image with a relatively high contrast in predetermined corresponding areas between the two images corrected by the image correction means to generate a combined image.

  • Patent number: 9025017
    Abstract: A method for detecting a capsule camera entering into or exiting the GI tract, includes (a) taking a first test image under the condition that an illumination system of the capsule camera is disabled; (b) taking a second test image under the same condition as the first test image; (c) comparing selected corresponding pixel values of the first test image and the second test image to determine if a significant change in pixel values has occurred; and (d) upon detecting the significant change in pixel values, determining if the capsule camera has entered or exited the GI tract, and performing operations appropriate to follow such determination.

  • Publication number: 20150116470
    Abstract: A method and apparatus where the output from a high intensity light source is controlled to produce well-exposed images/videos and to reduce automatically the intensity when an unsafe issue is detected in medical devices such as endoscopes and the like. The method and apparatus overcome problems to control light sources that have high-frequency noise, slow-response time, nonlinearity, and non-monotonic response time and to protect the patients' tissues from possible overheating/burning and the eyes of personnel and patients from possible direct exposure to high intensity light used in medical devices such as endoscopes and the like.

    Abstract: Systems, methods and devices are provided for illuminating tissue with monochromatic or broadband light and imaging light that has been reflected back from the tissue. Imaging may be white-light imaging or hyperspectral imaging. The system can be a stand-alone hyperspectral imaging system, integrated as part of an external video scope, or as an auxiliary imaging module on an external videoscope. Various elements of a video scope that is particularly suited for minimally invasive surgery is first presented and then its configurations suitable for hyperspectral imaging are explained.

  • Patent number: 9001214
    Abstract: A method, system and reference target for estimating spectral data on a selected one of three spectral information types is disclosed. Spectral information types comprise illumination of a scene, spectral sensitivity of an imager imaging the scene and reflectance of a surface in the scene. The method comprises obtaining a ranking order for plural sensor responses produced by the imager, each sensor responses being produced from a reference target in the scene, obtaining, from an alternate source, data on the other two spectral information types, determining a set of constraints, the set including, for each sequential pair combination of sensor responses when taken in said ranking order, a constraint determined in dependence on the ranking and on the other two spectral information types for the respective sensor responses and, in dependence on the ranking order and on the set of constraints, determining said spectral data that optimally satisfies said constraints.

  • Publication number: 20150092034
    Abstract: An endoscope system includes a light source apparatus for emitting narrow band light of green and violet in field sequential lighting, for endoscopic imaging. An image sensor has plural pixels arranged on an imaging surface, for imaging an object in a body cavity illuminated with the narrow band light, to output a pixel signal. The plural pixels include first and second pixels. The first pixel has a lower spectral sensitivity than the second pixel. A gain corrector is supplied with the pixel signal by the image sensor, for performing gain correction of multiplying the pixel signal of the first pixel by a gain value, so as to compensate for a difference in the spectral sensitivity of the first pixel from the second pixel. Also, a noise reduction device performs noise reduction of the pixel signal after the gain correction according to the gain value.

  • Publication number: 20150092033
    Abstract: Violet narrowband light Vn and green narrowband light Gn produced by a light source device are supplied to a complementary color type endoscope, and simultaneously applied to an observation object. From a complementary color type imaging device, first mixed pixels and second mixed pixels, which sense both of the violet narrowband light Vn and the green narrowband light Gn, are read out. The light amount ratio Z of the violet narrowband light Vn to the green narrowband light Gn is set within a predetermined range based on an optimal light amount ratio Z0 at which the proportion P1 of a violet narrowband light Vn component within a first mixed pixel signal becomes equal to the proportion P2 of a green narrowband light Gn component within a second mixed pixel signal. This improves color separability of an endoscope system.
