Filed: 1986-09-03
Abstract: PURPOSE:To display a processed picture just after graphic information of one screen is completely received by serially transferring graphic information for the unit of a block from an optical disk device and applying processings including expansion and rotation to a received picture in parallel with the transfer. CONSTITUTION:The image information by eight lines that is specified from the optical disk device is serially transmitted, received by an external interface 11, and sequentially stored in an image memory 12 and simultaneously in the buffer memory of a conversion part 13. It converts the resolution of said information and executes other processings including expansion and rotation. The processed partial image information is sequentially stored in a frame memory 14, and displayed on a CRT 15. At that point, the image information of next one block is transferred to the interface 11 from the optical disk device, and the same processing is repeated. Therefore the enlarged or rotated, processed picture is generated in the frame memory 14 and displayed on the CRT 15 almost at the same time when all the information of one screen is received.

IPC: G11B21/08
Filed: 1994-09-01
Abstract: PURPOSE: To attain high speed searching operation by controlling a tracking jump with the difference value between the actual moving amount of a pickup element and a precalculated total moving amount. CONSTITUTION: A difference operating circuit 20 outputs a difference value obtained by subtracting the count value counted in a number of tracking jumps counting circuit 18 from the number of tracks calculated in a number of jumping tracks calculating circuit 16 to a track jumping controller 17. During a high speed searching operation, a beam spot is stopped without reaching a target position. At this time, the tracking number of the difference value outputted by the difference operating circuit 20 in the stopped position is fetched into the controller 17. The controller 17 makes a tracking state to be in an on-state temporarily and generates a tracking jump command signal making the objective lens 13d move to the target position based on the tracking number of the difference value to make again the objective lens 13d jump toward the objective position automatically.  Thus, the high speed of the searching operation is made possible effectively.
