摘要:
In an optical pick-up apparatus for recording to or reproducing from an optical information recording medium, the optical pick-up apparatus includes: a light source for emitting light flux; a light converging optical system having an aperture and an objective lens and converging the light flux emitted from the light source on the optical information recording medium; a photodetector for detecting light reflected from the optical information recording medium; and a driving section for driving the objective lens and the aperture in association with the objective lens. A non-parallel light is incident on the objective lens, the light converging optical system includes a first part and a second part which is more apart from an optical axis of the light converging optical system than the first part, and the light flux passed through the first part is converged on an information recording surface of the optical information recording medium through a transparent substrate of the optical information recording medium so that a wavefront aberration on the information recording surface is not more than 0.07nullrms, and the light flux passed through the second part generates a spherical aberration.

摘要:
There is described a method for providing processed image data to a client, who requests an image-processing service from an image-processing service provider. The processed image data are generated by processing an original image submitted by the client as an object of the image-processing service. The method includes the steps of acquiring original image data, which include expanded color-range image data, from the original image; determining a first optimizing condition for generating output-referred image data from device characteristic data in respect to the output device, in order to generate optimizing condition data; storing the original image data including the expanded color-range image data and the optimizing condition data, while correlating them; and providing the original image data including the expanded color-range image data and the first optimizing condition data, stored in the storing step, to the client, based on a providing procedure established in advance.
