Filed: 1998-11-25
Abstract: PROBLEM TO BE SOLVED: To suppress a noise caused in the case of expansion even when an object image includes many high frequency components by controlling an aperture gain on the basis of the high frequency components included in a photographing image signal. SOLUTION: When a shutter button 34 is depressed, a CCD imager 12 photographs an object image, and a color separation circuit 18 outputs a corresponding photographing image signal (luminance signal and color difference signal). An HPF 20 detects a high frequency component from the luminance signal and an integration circuit 26 integrates the detected high frequency component. A microcomputer 28 outputs an aperture gain on the basis of the integration signal obtained in this way and an edge emphasizing circuit 21 applies edge emphasizing to the photographing image signal according to the aperture gain. The aperture gain is decreased more as the value of the integration signal is more increased. A memory card 32 stores the photographing image signal which has undergone the edge emphasizing after JPEG compression.

IPC: H04W52/02
Filed: 1999-11-26
Abstract: PROBLEM TO BE SOLVED: To allow a plurality of users to share the same physical resource in common by transmitting information denoting start of an inactive period after an active data transmission period or permission of opened connection between a mobile station and a network, so as to maintain physical connection of a packet radio service, even during the inactive period. SOLUTION: A control unit 103 of the mobile station controls a signal processing block 133, encodes a MAC header parameter of an RLC block and controls a transmission block to transmit the RLC block. When the transmitted RLC block is a final block of TBF data blocks, a parameter CV of the MAC header is set to 0 and a TR (TBF open) is set to 1, and the RLC block is transmitted. With this, the TBF is opened. When the transmitted RLC block is final block in a buffer, the parameter CV is set to 0 and the TR is set to 0 and the RLC block is sent. Thus, although the TBF is not opened, but a data flow goes into an inactive period.
