Abstract: A fundus oculi observation device comprises: a first image forming part for optically obtaining data and then forming a fluorescence image of a fundus oculi of an eye administered with a fluorescent agent in advance based on the obtained data; a second image forming part for optically obtaining data and then forming a tomographic image of the fundus oculi based on the obtained data; a display; and a controller for causing said display to display said fluorescence image formed by said first image forming part side-by-side with said tomographic image formed by said second image forming part, as well as to display cross-sectional position information that represents a cross-sectional position of said tomographic image in said fluorescence image by overlapping it with said fluorescent image.

Abstract: A fundus examination apparatus includes an illumination optical system (20), which illuminates a fundus by fundus illumination light, an imaging optical system (21), which photographs a fundus image based on a polarization property of reflected illumination light, and a picture signal processing device, which processes a signal output from the imaging optical system; and the imaging optical system includes a phase plate array (42) that a plurality of unit constitutional plates (U1) is arranged in a matrix in a plane; each of the unit constitutional plates comprising four or more micro phase plates (44a-44d), a polarizer (43), which polarizes the reflected illumination light passing through the phase plate array (42) into a predetermined polarization direction, and an image pickup device (5a) that a plurality of constitutional units (U2) is arranged in a matrix in a plane; each of the constitutional units comprising four or more pixels (Ga-Gd).

Abstract: A medical image processor according to the present invention is used for analyzing eye fundus images 28 and 29, and comprises an image monitor capable of almost simultaneously displaying two images, a keyboard 23 for setting at least one reference point P1 to the eye fundus image 28, a mouse 24 for setting a correlation detection area Q to the other eye fundus image 29 with reference to the reference point P1, an image processing unit 21 for calculating a correlation between image information of the reference point P1 and image information of each point in the correlation detection area Q, and a system monitor 27 for displaying a result of the calculation made by the image processing unit 21 as a correlation table in which a vertical direction and a horizontal direction show position of each point in the detection area and which indicates the degree of correlation between the image information of the reference point and the image information of each point.
