    摘要： An ophthalmic apparatus of an exemplary aspect performs the first and second OCT scans on a subject's eye. The first OCT scan is performed on the first region including the first site of the subject's eye, and the second OCT scan is performed on the second region including the second site. The ophthalmic apparatus acquires the first deviation information of the subject's eye prior to the first OCT scan and performs alignment, and also acquires the second deviation information of the subject's eye prior to the second OCT scan and performs alignment. The ophthalmic apparatus calculates the distance between the first site and the second site based on the first data acquired through the first OCT scan and second data acquired through the second OCT scan.

    摘要： An evaluation apparatus includes a display screen that displays an image; a gaze point detection unit that detects a position of a gaze point of a subject who observes the display screen, a display control unit that performs instruction display operation of displaying, on the display screen, a task target object to be gazed at by the subject and instruction information for instructing the subject to solve a task related to the task target object, a region setting unit that sets, on the display screen, a task region corresponding to the task target object and an instruction region corresponding to the instruction information, a determination unit that determines whether the gaze point is present in the task region and the instruction region during an instruction display period in which the instruction display operation is performed on the basis of positional data of the gaze point, an arithmetic unit that calculates instruction movement course data indicating a course of movement of the gaze point during the instruction display period on the basis of a determination result, and an evaluation unit that obtains evaluation data of the subject on the basis of the instruction movement course data.

    摘要： A gaze detection apparatus performs a calibration operation including displaying a target image in multiple positions on a display screen sequentially, setting, in the display screen, corresponding areas corresponding to the target images displayed on the display screen sequentially, and calculating positional data of points of regard in display periods in which the respective target images are displayed; determines, with respect to each of the target images, whether the positional data of the point of regard that is calculated in the calibration operation is present within the corresponding area; when the number of valid target images that are the target images on each of which it is determined that the positional data of the point of regard is present within the corresponding area is at or above a threshold, outputs the positional data of the points of regard of the valid target images as calibration data; and, when the number of the valid target images is under the threshold, causes the calibration operation to be repeated.
