Inventor: MIYANO KYOSUKE
IPC: G11B7/09
Filed: 2003-08-05
Abstract: <P>PROBLEM TO BE SOLVED: To detect the tilting and the light quantity of an optical recording medium by using an optical system for recording/reproducing an optical recording medium.  <P>SOLUTION: When a push-pull signal is obtained from the detected signal of each photodetector and this is input to a subtractor in a radial skew signal processing part 116, it is inputted to the subtractor after gain control at auto gain control (AGC) circuits 44, 45 and 46 so that the output signal levels of two light receiving elements divided in a radial direction for each spot becomes equal to each other. By using the AGC circuits, the overall optical shifting of the radial direction between the photodetector and a return light caused by the attaching position error of each photodetector, the (z) tone error of a grating, visual field shifting or the like is eliminated, a good wobble signal is detected, the phase fluctuation amounts of both side spots become symmetrical at a main spot by radial skew, and more accurate radial skew is detected.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Title: Image display method
Inventor: ARAYA SHUNTARO
IPC: G06F3/0484
Filed: 2003-08-06
Abstract: <P>PROBLEM TO BE SOLVED: To provide an image display method which makes image search effective by intuitively grasping the meaning of an image arrangement on a screen.  <P>SOLUTION: A display control section obtains the attribute of each display object image and sets a center point for each attribute value on the screen. The center points are scattered within the screen. The display control section arranges a thumbnail image of the display object image in the vicinity of the center points related to the attribute values of the images. Thus, thumbnail images having the same attribute value are arranged in a concentrated manner. As the number of sheets of the thumbnail image group increases, the group is arranged closer to the center of the screen. When a time sequence display process is started, the display control section successively switches the display object images for every few seconds from the images of an older interval to newer images. Thus, each image group moves on the screen in accordance with the time sequential change in the number of sheets.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
