摘要 |
In order to perform accurate evaluation for enhanced depth imaging (EDI) in which a tomographic image of a retina has a low luminance value in large part, provided is an optical coherence tomographic imaging apparatus for acquiring an image of an object to be inspected by irradiating the object to be inspected with measuring light and causing return light from the object to be inspected to interfere with reference light, the optical coherence tomographic imaging apparatus including: a unit for setting an imaging parameter of the image; a unit for selecting an image quality evaluation index in accordance with the imaging parameter; a unit for acquiring an image characteristic amount from the acquired image in accordance with the set imaging parameter; and a unit for evaluating image quality of the image based on the image characteristic amount and the image quality evaluation index. |

1. An ophthalmologic apparatus for evaluating a tomographic image of an object to be inspected, the tomographic image being obtained based on combined light of return light from the object to be inspected and reference light, the return light being obtained by irradiating the object to be inspected with measuring light, the reference light corresponding to the measuring light, the ophthalmologic apparatus comprising:
a selection unit configured to select an evaluation method based on a position of a coherence gate, among a plurality of evaluation methods; and an evaluating unit configured to evaluate the tomographic image based on the evaluation method selected by the selection unit. |
