Patent number: 6798972Abstract: There is provided an image reproducing apparatus and an image reproducing method which allow reproducing speed to be shifted instantly when a change of the reproducing speed is requested in a multi-channel AV (Audio Visual) server. When a request to reproduce an image is made, the image reproducing apparatus reads image data of the part corresponding to the requested reproducing speed out of the HDDs to store in a temporary storage section. Then, an image output I/F reads the image data stored in the temporary storage section and structures a reproduced image by using the image data. In this case, a controller section controls a pattern in reading the divisional data by the image output I/F and structures a reproduced image by means of various reproducing speeds by this reading pattern.Type: GrantFiled: March 24, 2000Date of Patent: September 28, 2004Assignee: Sony CorporationInventors: Norikazu Ito, Satoshi Yoneya, Masakazu Yoshimoto, Satoshi Katsuo, Jun Yoshikawa, Shouji Nakamura, Tomohisa Shiga, Masaki Hirose
