  • Patent number: 9338339
    Abstract: The image processing apparatus includes an area dividing part that divides an input image produced by an image pickup system into plural image areas whose evaluation values are mutually different. The evaluation value is obtained by using a response function of the image pickup system. The apparatus further includes a processing part that performs image processing to produce an output image whose definition is higher than that of the input image by using the response functions different for the respective image areas.

  • Patent number: 9155464
    Abstract: A visual field examination system measures the visual field of an eye. Quantitative information of a 3D retinal layer structure is acquired by detecting a range in which a peak of a retinal reflectance distribution obtained by OCT scanning is lost. A position of the fovea of the eye fundus is identified based on the acquired information. A location of a range in which the peak of the retinal reflectance distribution is lost is specified in a 2D fundus image based on the position of the fovea, and the specified location is marked on a region of the 2D fundus image. A position of the marked region is detected, and a visual inspection field region is generated based on the detection. Visual field examination points of the visual inspection field region are presented to the eye through a visual field dome for carrying out visual field examination of the eye.
