An information processing apparatus includes a determination unit configured to determine, as a threshold value to which a signal intensity value corresponding to a shadow region is compared, a value different from a threshold value to which a signal intensity value corresponding to a region other than the shadow region is compared.

Information processing apparatus, information processing method, and program

An inspection apparatus includes: a first scanning member scanning an object by reciprocating illumination light in a main scanning direction; a second scanning member scanning the object at a constant speed in a sub-scanning direction; a scanning control unit allowing the first and second scanning members to perform 2D scans of the object with the illumination light in first and second fields within a data acquisition area; and a data acquisition unit acquiring data based on the illumination light returned from the first and second fields. The scanning control unit sets the second field by shifting the first field by a predetermined amount in the sub-scanning direction, the predetermined amount determined such that the closer to the scanning center in the main scanning direction within the data acquisition area, the more regular the interval between the first and second fields in the sub-scanning direction.

Inspection apparatus, method for controlling inspection apparatus, and program

An image processing apparatus includes a generation unit and a display control unit. The generation unit generates a subtraction image using a first region and a second region, the first region being a portion of a first fundus image acquired by performing autofluorescence imaging on a fundus of an eye to be inspected, the second region being a portion of a second fundus image acquired by performing autofluorescence imaging on the fundus of the eye to be inspected at a time different from that of the first fundus image and being at a position corresponding to the first region. The display control unit causes a display unit to display an image generated by superimposing information regarding the subtraction image at a position corresponding to the first and second regions on a fundus image acquired by performing autofluorescence imaging on the fundus.

In pattern matching for detecting a positional difference between tomographic images of an eye to be examined, a target within the eye to be examined which causes a reduction in the similarity even though there is no positional difference, is selectively excluded.

Image processing apparatus, image processing method, and program

In order to detect a position alignment state between an apparatus and an eye to be inspected in a working distance direction with high precision at a high speed in the apparatus side, an ophthalmologic apparatus is disclosed. The position alignment state between the eye to be inspected and the apparatus in the working distance direction is detected by evaluating a contrast of an index image that is obtained as a reflection image of an index projected onto an anterior ocular segment, and a contrast of the index image is evaluated using a ratio or a difference between pixel numbers of the index image in at least two or more gray scale values.

A image processing apparatus includes a selection unit configured to select either first color tone conversion processing or second color tone conversion processing having a ratio of red wavelength component set lower than either blue wavelength or green wavelength components with respect to the first color tone conversion processing, and a color tone conversion unit configured to convert a color of a fundus image by the selected color tone conversion processing.

Image processing apparatus for fundus image, image processing method for fundus image, and program medium

A fundus image is displayed, which enables accurate positioning and focusing to be easily performed with respect to an eye to be examined even on a small display unit by selecting a display magnification. At a first display magnification, an opening portion 'm' of a mask specifying a predetermined angle of field of the fundus is displayed with no part missed in both of horizontal and vertical directions of a display unit. At a second display magnification, the opening 'm' of the mask is displayed with no part missed in the horizontal direction in the display area of the display unitand with some part missed in the vertical direction. Thus, the second display magnification is used to observe an essential part when the fundus is accurately observed.
