Abstract: Disclosed are an encoding apparatus and decoding apparatus for a depth image and an encoding method and decoding method. To process a depth image according to an intra prediction mode, the encoding apparatus or the decoding apparatus may use a representative mode from a DC mode of an SDC mode, a planar mode, or DMM1. Further, to process the depth image according to an intra prediction mode, the encoding apparatus or the decoding apparatus may use a representative mode from a planar mode or DMM1.

Abstract: Disclosed is a mobile communication terminal having a subscriber identity module (SIM) card. The mobile communication terminal includes a memory unit for storing use-history information of the SIM card inserted into the mobile communication terminal according to a subscriber identity number of the inserted SIM card, and a controller for determining the subscriber identity number of the inserted SIM card, determining whether a predetermined storage area corresponding to the subscriber identity number exists in the memory unit, and generating the predetermined storage area in the memory unit when the predetermined storage area does not exist in the memory unit. Further, it is possible to search the use-history information stored in a storage area corresponding to the subscriber identity number of each SIM card carried by a user. Therefore, the security for the use-history information of the SIM card can be ensured.
