Image retention and stitching for minimal-flash eye disease diagnosis

A computer program product for minimizing exposure of a retina to flash during image gathering for diagnosis, the computer program product comprising a non-transitory computer-readable storage medium containing computer program code for:

• capturing a first retinal image of a first retinal region by flashing the first retinal region responsive to determining a capturing device is focused on the first retinal region;
• capturing a second retinal image of a second retinal region by flashing the second retinal region responsive to determining the capturing device is focused on the second retinal region, the first retinal image and the second retinal image together forming a plurality of retinal images;
• determining whether to again flash the first retinal region by:
• determining that a first portion of the first retinal image does not meet a criterion while a second portion of the first retinal image does meet the criterion;
• identifying a portion of the retina depicted in the first portion that does not meet the criterion;
• determining whether the portion of the retina is depicted in a third portion of the second image;
• determining whether the third portion meets the criterion;
• responsive to determining that the third portion meets the criterion, determining to not again flash the first retinal region and to perform the diagnosis using the plurality of retinal images;
• and
• responsive to determining that the portion of the retina is not depicted in the second image, determining to again flash the first retinal region in connection with capturing an additional image of the first retinal region.

A computer program product for minimizing exposure of a retina to flash during image gathering for diagnosis, the computer program product comprising a non-transitory computer-readable storage medium containing computer program code that comprises:

• a first module for:
• capturing a first retinal image of a first retinal region by flashing the first retinal region responsive to determining a capturing device is focused on the first retinal region;
• and
• capturing a second retinal image of a second retinal region by flashing the second retinal region responsive to determining the capturing device is focused on the second retinal region, the first retinal image and the second retinal image together forming a plurality of retinal images;
• a second module for determining whether to again flash the first retinal region by:
• determining that a first portion of the first retinal image does not meet a criterion while a second portion of the first retinal image does meet the criterion;
• identifying a portion of the retina depicted in the first portion that does not meet the criterion;
• determining whether the portion of the retina is depicted in a third portion of the second image;
• and
• determining whether the third portion meets the criterion;
• a third module for, responsive to determining that the third portion meets the criterion,
• determining to not again flash the first retinal region and to perform the diagnosis using the plurality of retinal images;
• and
• a fourth module for, responsive to determining that the portion of the retina is not depicted in the second image, determining to again flash the first retinal region in connection with capturing an additional image of the first retinal region.
