The present invention is to provide an improved aberration correction device formed by inserting an electro-optic panel such as a liquid crystal panel in an image-formation optical system to correct aberrations in the image-formation optical system, characterized in that such a correction device is capable of correcting three or more kinds of aberrations using only one electro-optic panel. In an aspect, a method is provided that operates to provide time management for mobile media that is distributed over a network. Next, data or information relevant to that person is automatically retrieved from at least one electronic database. The testing can be done at assembly time and the results stored in nonvolatile memory. The system and method can include provisions to suppress certain enlarged views.
