摘要： In the case where an output value of a document reading section for at least any of R, G and B is out of a range between a first reference value and a second reference value due to a change in an output value of a reading device caused by an electrical noise, a change of supply voltage, etc. when a document is being read, a second color conversion table is created in accordance with the above change by expanding ranges in a first color conversion table, which ranges are around predetermined first and second reference values and included in regions of RGB color system associated respectively with predetermined tone values of Y, M and C. Using the second color conversion table thus obtained, a color conversion is carried out from the RGB color system into the YMC color system.

摘要： An optical information recording method includes the following steps. A converting step is converting a light beam into an information beam carrying information by using a spatial beam modulator. A focusing step is focusing the information beam on an optical information recording medium including an information recording layer. An irradiating step is irradiating the optical information recording medium with a reference beam and the information beam so that the reference beam and the information beam intersect with each other on the information recording layer by using an optical component. A rotating step is rotating the optical information recording medium or the optical component by using a drive unit for performing angle-multiplex recording. A management information recording step is recording management information at two or more relative angles having an angle interval smaller than twice at least a first null angle.

摘要： Multi-carrier transmission is performed without inserting a repetitive signal into guard interval periods. A transmitter provides guard interval periods by using a null signal to save transmission power and prevent the deterioration of the SN ratio. Delayed waves at the head of each received symbol cause high-frequency waves to occur and carriers to interfere with one another. Accordingly, a receiver adds a component following each received symbol to a delayed-wave component at the head of the received symbol. As a result, the delayed-wave component at the head of the received symbol and the added component become continuous in wave form and subcarriers do not interfere with each other.
