  • Publication number: 20220369904
    Abstract: An endoscope system that illuminates an object and captures reflected light from the object includes a control processor. The control processor acquires an examination image and determines whether the examination image shows a swallowing state or a non-swallowing state. In addition, the control processor detects a high pixel value region from the examination image and determines that the examination image shows the swallowing state in a case in which an area of the high pixel value region is equal to or greater than a first threshold value. Further, the control processor performs grayscale conversion on the examination image to obtain a grayscale image and performs a binarization process for obtaining the high pixel value region in a case in which a density value of a pixel of the grayscale image is equal to or greater than a second threshold value.

  • Patent number: 10521904
    Abstract: A region identifier identifies a region within a diagnostic image corresponding to one of plural predetermined clinical findings according to a first feature value from a feature value detector. A level detector performs level detection of the region at one of plural levels associated with the clinical findings for evaluation of the clinical findings according to a second feature value from a feature value detector. A color mapped image generator generates a color mapped image by color mapping of the diagnostic image with a display color associated with respectively the clinical findings and chromaticity of the display color associated with the levels. A monitor display panel is caused to display the color mapped image by control of a display control unit. Preferably, the diagnostic image is an image generated by an endoscope. The color mapped image generator is included in a processing apparatus.

  • Patent number: 10362928
    Abstract: There is provided an image processing apparatus, method, and program for an endoscope image having a high degree of freedom of color assignment according to the shape feature of a structure. A structure region image is generated by extracting one or more structure regions from an image signal obtained by imaging an observation target in the living body. A shape feature amount of the structure region is calculated based on the structure region image, and a color corresponding to the feature amount is assigned to the structure region. A reduced original image is generated by performing processing for reducing at least one of the color or the contrast on an original image in which the observation target is drawn in color. A composite image is generated by superimposing the reduced original image and the structure region image subjected to the color assignment.

  • Patent number: 9322639
    Abstract: A calibration jig allowing simple and repeatable calibration of a probe optical tomographic apparatus is disclosed. The jig includes a holding member removably attachable to an attachment section of the apparatus and a reflective surface held by the holding member. The reflective surface reflects measurement light emitted from an emitting section of the attachment section and directs reflected light back to the emitting section. If a probe of the apparatus is covered with a sheath, the jig may include a light transmitting member, which generates the same dispersion as dispersion at the sheath, between the emitting section and the reflective surface. The reflective surface may be a single reflective surface disposed within an area corresponding to twice a coherence length of the laser light with a zero path position of the reflective surface being the center of the area.

  • Patent number: 7970029
    Abstract: Semiconductor lasers are driven such that high output laser beams are stably obtained without a long start up time. The light outputs of a plurality of semiconductor lasers are detected by photodetectors. The semiconductor lasers are driven by automatic power control based on comparison results between the output of the photodetectors and a set value corresponding to a target light output for the semiconductor lasers. A correction pattern that corrects the set value and/or the output of the photodetectors such that the actual light output becomes uniform is generated in advance. The set value and/or the output are varied according to the correction pattern for a predetermined period of time from initiation of drive. A single correction pattern is employed in common with respect to the plurality of semiconductor lasers.

  • Patent number: 7944568
    Abstract: When reflection light, reflected from a measurement target that has been irradiated with measurement light in such a manner to scan the measurement target, and reference light are combined in each wavelength sweep, interference light is detected as interference signals. When a thinning region in which the interference signals obtained by detecting the interference light in each wavelength sweep are thinned so that the interference signals that are used to produce the tomographic image remain is set, thinning is performed on the plurality of interference signals in the thinning region. Light intensity information about the measurement target in the thinning region is obtained, based on the interference signals for the respective wavelength sweeps, the interference signals remaining after thinning. The tomographic image in the thinning region is produced based on the obtained light intensity information.

  • Patent number: 7864331
    Abstract: A first light beam and a second light beam having discrete wavelength bands are emitted form a light source unit, and enter a light divider. The light divider separates each light beam into a measuring light beam and a reference light beam. The measuring light beams are irradiated on a measurement target, and reflected light beams, which are reflected at various depth positions of the measurement target, are caused to enter a combiner. The reference light beams propagate through optical fibers to enter the combiner. Interference light beams formed by the reflected light beams and the reference light beams for each of the first and second light beams are photoelectrically converted into interference signals. A tomographic image is obtained employing the interference signals for each of the first and second light beams.
