Abstract: An image processing device for automatically setting the accumulation time (exposure time) in accordance with the illuminance even in a dark environment and smoothly following the motion of an object. The image processing device includes: gain control means (7) for performing gain control of a video signal from an imaging element (6) which focuses a signal from an iris (2) controlling the light quantity of the optical signal coming from outside and outputs a video signal; signal processing means (9) for signal-processing an output signal from the gain control means (7); and imaging control means (25) for controlling the opening degree of the iris (2), the exposure time of the imaging element (6), and the gain amount of the gain control means according to the video signal from the signal processing means (9).

Abstract: In a radio communication system where A-DPCH (Associated-Dedicated Physical Channel) to which soft hand-over is applied and HS-DPCCH (High Speed-Dedicated Physical Control Channel) to which hard hand-over is applied are mixed, in order to perform appropriate transmission power control of the HS-DPCCH, an HO judging section 11 judges whether the A-DPCH is in a soft hand-over state, and a transmission radio section 23, when the A-DPCH is not in the soft hand-over state, performs transmission power control of the HS-DPCCH according to a TPC command for the A-DPCH transmitted on the A-DPCH, and when the A-DPCH is in the soft hand-over state, performs transmission power control of the HS-DPCCH according to a TPC command for the HS-DPCCH transmitted on the HS-DPCCH.
