Patent number: 8320685Abstract: Data can be transferred from a picture processing section to an encoding section without necessity of using an external memory. In addition, with internal data transfer having a wider band than an external memory, data can be processed at high speed. An entire picture 41 as an original picture is divided into six blocks of (64×4) pixels each. An enlargement process is performed for each block. Data of blocks are read in the order of blocks 1, 2, 3, and so forth. A size changing section processes a first block and generates picture data of a block 42 of (128×8) pixels. From this picture data 42, macroblocks 43 of (16×8) pixels each are read and encoded. As a result, JPEG data 44 are obtained. A code rearrangement section rearranges the order of the JPEG data 46 in the unit of a block. As a result, JPEG data 48 are generated. When JPEG data 48 are decoded in this order, a decoded picture 49 whose block order matches an area 41 of the original picture is obtained.Type: GrantFiled: January 12, 2006Date of Patent: November 27, 2012Assignee: Sony CorporationInventors: Koji Ozaki, Fumiaki Kato, Kenichi Sakai

Patent number: 7992783Abstract: In a mobile terminal, a control section monitors a battery residual amount at a power supply section, if the battery residual amount is less than a preset threshold, it refers to the states of various flags stored in a flag table at a memory section. Subsequently, if the control section judges it is before exit after entry for a service for the object of a lock temporary release and an entry and exit usage service, it changes a noncontact IC card function section to a lock temporary release state. This allows the noncontact IC card function to be in a lock temporary release state, just before the power supply is turned off, even if the battery residual amount is low. Therefore, when the commuter gets off a train and passes through a station ticket gate, the commuter may use the noncontact IC card function.Type: GrantFiled: October 23, 2007Date of Patent: August 9, 2011Assignee: Casio Hitachi Mobile Communications Co., Ltd.Inventor: Kenichi Sakai
