Abstract
An image processing apparatus has an acquisition unit which acquires a second tomogram related to a first tomogram of an eye to be examined based on position information of an eye fundus of the eye to be examined according to a predetermined rule; and a display control unit which displays the first tomogram and the second tomogram on a display unit.
Claims7
An image processing apparatus comprising:
- an image acquisition unit configured to acquire a tomogram group including a plurality of tomograms obtained by capturing tomograms of an eye to be examined;
- a reference tomographic plane setting unit configured to set a reference tomographic plane indicating a tomographic plane serving as a reference of the tomogram group acquired by said image acquisition unit;
- a selection unit configured to select one tomogram from the plurality of tomograms and a tomogram at a position plane-symmetric to the one tomogram with respect to the reference tomographic plane from the plurality of tomograms;
- a measurement unit configured to measure differences between distributions of layer structures included in the tomogram selected by said selection unit;
- and
- a display unit configured to display at least one of the tomogram selected by said selection unit and a measurement result of the differences between distributions of layer structures.
