Title: Method for estimating image
Inventor: HASEBE TAKASHI
IPC: H04N1/405
Filed: 1986-11-14
Abstract: PURPOSE:To obtain a half tone image approximate to an original half tone image by dividing plural kinds of scanning apertures into a low space frequency area and a high space frequency area to use respective apertures. CONSTITUTION:A reference scanning aperture D is set up (k) and the coincidence and discrepancy of a density pattern of the scanning aperture D is checked (l). At the time of coincidence of the density pattern, any one of large scanning apertures D-G having different size respectively is selected on the basis of a prescribed conditional formula. At the time of discrepancy in the density pattern, any one of small scanning apertures C-A, Z having different size is selected on the basis of the decision of the density pattern. After ending the selection of the scanning aperture, a half tone image level is estimated (o) on the basis of the selected scanning aperture. Then, image processing such as expansion or contraction is executed on the basis of the estimated half tone image level and the processed result is binarized.

Title: Data read circuit for optical disk device
Inventor: YANAGI SHIGETOMO
IPC: G11B7/00
Filed: 1989-10-20
Abstract: PURPOSE:To cancel read error by executing a read operation normally by executing focus control so that a write beam can be just focused, and executing a retry operation after switching function to the focus control so that a read beam can be just focused when read is disabled. CONSTITUTION:A control means 24 is provided to normally execute the read operation by setting the set information of a write beam focal point setting means 20 to a focus servo means 18, and to execute the read operation again by switching the information to the set information of a read beam focal point setting means 22 when the uncorrectable read error is generated. When focus conditions for the two beam of various wavelengths are deviated during use and the read beam not to execute the focus servo is defocused so as to generated the uncorrectable read error, offset switching is executed to add the focal point information of the read beam set in advance to a focus error signal FES. Thus, even when read is disabled during focus control, the read error is canceled without fail by the retry operation.
