  • Patent number: 10561311
    Abstract: An ophthalmic imaging apparatus according to an exemplary embodiment includes a three dimensional data generator, an analyzer, and a display controller. The three dimensional data generator generates three dimensional data by scanning a three dimensional region of a subject's eye using optical coherence tomography (OCT). The analyzer generates a plurality of analysis maps by analyzing a plurality of pieces of partial three dimensional data in the three dimensional data. The display controller displays the plurality of analysis maps over a front image of the subject's eye on a display device.

  • Patent number: 6055648
    Abstract: The floating point data stored in an arbitrary cell is processed on the basis of a particular formula (S401), if an error due to column truncation occurs in a result of computation (S402) then the all the floating point data is converted to the fixed point data (S405), and the error occurring due to the floating point data is recovered automatically thereby improving the convenience of the recovery process.
