Abstract

An information processing apparatus includes a scan control unit configured to control a scan with measurement light for generating a three-dimensional motion contrast image of the fundus, and a display control unit configured to display information indicating a progress of the scan on a display unit.

First claim

What is claimed is:

1 . An information processing apparatus comprising:
a scan control unit configured to control a scan with measurement light for generating a three-dimensional motion contrast image of a fundus; and a display control unit configured to display information indicating a progress of the scan on a display unit.

2 . The information processing apparatus according to claim 1 , wherein the display control unit performs control to superimpose and display an image indicating the progress on a captured image of an imaging range corresponding to the three-dimensional motion contrast image.

3 . The information processing apparatus according to claim 2 , wherein the display control unit performs control to superimpose and display an image for distinguishing between an area where the scan is completed and an area where the scan is not completed on the captured image.

4 . The information processing apparatus according to claim 3 , further comprising a generation unit configured to generate a two-dimensional projection image based on a tomographic image of the area where the scan is completed, wherein the display control unit performs control to superimpose and display the two-dimensional projection image generated by the generation unit on a corresponding area of the captured image.

5 . The information processing apparatus according to claim 1 , wherein the display control unit performs control to display a progress rate as information indicating the progress.

6 . The information processing apparatus according to claim 1 , wherein the display control unit performs control to display at least either one of an elapsed time and a remaining time related to the scan as information indicating the progress.

7 . The information processing apparatus according to claim 1 , wherein the display control unit performs control to display a bar graph indicating the progress.

8 . The information processing apparatus according to claim 1 , wherein the display control unit performs control to display information indicating the progress on a tomographic image obtained as a result of the scan.

9 . The information processing apparatus according to claim 1 , wherein, in a case where a scanning line where a scan is performed is registered as a line subjected to a rescan, the display control unit performs control to display information indicating a progress related to the rescan.

10 . The information processing apparatus according to claim 9 , wherein the display control unit performs control to superimpose and display the information indicating the progress related to the rescan on a captured image of an imaging range corresponding to the three-dimensional motion contrast image.

11 . The information processing apparatus according to claim 10 , wherein the display control unit performs control to superimpose and display an image indicating a scanning line subjected to the rescan on the captured image.

12 . The information processing apparatus according to claim 9 , wherein the display control unit performs control to display, on a same axis, a bar graph indicating a progress related to the scan and a progress related to the rescan.

13 . An information processing method to be performed by an information processing apparatus, the method comprising:
controlling a scan with measurement light for generating a three-dimensional motion contrast image of a fundus; and displaying information indicating a progress of the scan on a display unit.

14 . A non-transitory storage medium storing a program for causing a computer to function as:
a scan control unit configured to control a scan with measurement light for generating a three-dimensional motion contrast image of a fundus; and a display control unit configured to display information indicating a progress of the scan on a display unit.
