An imaginary object plane is set in front of an imaging device body (plane setting step). A part of optical conditions of optical lenses are changed as variables, and positions of points (pixel observation points) on the imaginary object plane where lights coming from pixels of a solid-state imaging element and back-projected through the optical lenses are calculated (pixel observation point calculating step). The dispersion in position of the calculated pixel observation points is evaluated (evaluating step). Finally, a set of values of the variables giving maximum evaluated dispersion of the calculated pixel observation points is determined as optimum optical condition of the optical lenses (condition determining step). This reduces the number of pixels which image the same portions of the target object, making it possible to reduce portions of the same image information in multiple unit images, and to stably obtain a reconstructed image having a high definition.

A method / system preserves annotations of different pathological conditions or changes that are recognized on cross-sections within a three dimensional volume of a patient's eye so that the annotations are maintained in a visible state in an en face projection produced with a SVP technique. It is thus possible to coregister the annotated conditions or changes with other types of two dimensional en face images such as images from other ophthalmic devices (e.g., angiography device, microperimetry device, autofluorescence device, fundal photography device.). The annotations are also maintained in a visible state in the coregistered image.

A radio line is easily influenced in its nature by attenuation or reflection of an electromagnetic wave or the like and the surrounding environment.

A distribution server is provided with a multiplexer for multiplexing information indicating the transmission start time for the image data and a switching unit for switching an image bit rate in response to a request from the receiving terminal. The receiving terminal uses information indicating a transmission start time for the image data, monitors the receiving bit rate and sends out a request for transmission of the most-suitable image bit rate in response to a comparison thereof.
