  • Patent number: 10335026
    Abstract: An image processing apparatus includes a processor that acquires a plurality of sets of tomographic signals acquired by an image sensor, and generates a representative value in each pixel position of the tomographic image, using the plurality of sets of tomographic signals, and generates the tomographic image with the representative value in each pixel position as a pixel value by determining a target region in which contrast is reduced in the tomographic image, using at least one set of tomographic signals, out of the plurality of sets of tomographic signals, and estimating an estimation value, in each pixel position of the target region, by performing statistical processing on a plurality of tomographic signals corresponding to the pixel position, out of the plurality of sets of tomographic signals. The tomographic image is generated with the estimation value as the representative value in the target region.

  • Patent number: 10123692
    Abstract: An ophthalmologic apparatus wherein auto alignment and manual alignment can be selectively used to enhance alignment accuracy between an eye to be inspected and an ophthalmic part includes an ophthalmic part that detects an eye to be inspected, a fixing part, a movable part on which the ophthalmic part is placed and configured to be movable with respect to the fixing unit in a horizontal direction, a drive part that transmits electric drive force for horizontal movement of the movable part, an alignment detection unit that detects a relative position between the eye to be inspected and ophthalmic part, a controller that controls the movable part based on a detection result from the alignment detection unit, and a drive force transmit switching unit that switches whether or not to execute transmission of the drive force from the drive part to the movable part.

  • Publication number: 20180192870
    Abstract: An image processing apparatus that processes a tomographic image generated by using tomographic signals acquired by subjecting a subject to optical coherence tomographic imaging, includes an acquiring unit configured to acquire the tomographic signals, and a generation unit configured to generate a tomographic image based on a representative value in each pixel position of the tomographic image, generated by using the tomographic signals, the generation unit includes a region determination unit configured to determine a target region where contrast is reduced in the tomographic image, by using tomographic signals, and an estimation unit configured to estimate an estimation value, by performing statistical processing on tomographic signals corresponding to a pixel position of the tomographic image out of the tomographic signals, and the generation unit generates the tomographic image with the estimation value as the representative value in the target region.
