Abstract
본 발명은 프로젝터/캠코더에 관한 것으로, 특히 프로젝터/캠코더 기능 수행시 각 기능부의 동작상태를 최적화하여 기기의 특성을 향상시킨 프로젝터/캠코더 구동제어장치 및 방법에 관한 것이다.The present invention relates to a projector / camcorder, and more particularly, to a projector / camcorder driving control apparatus and method for optimizing an operation state of each functional unit when performing a projector / camcorder function to improve device characteristics.
상기와 같은 본 발명의 프로젝터/캠코더 구동제어장치는 프로젝터 기능을 가진 캠코더 기기에 있어서, LCD 패널과 램프, 냉각용 팬을 포함하는 LCD 어셈블리부, 상기 기기의 전원을 공급하는 전원공급부, 상기 전원공급부에서 출력되는 전원을 차단/공급하는 메인스위치, 보조스위치, 상기 메인스위치에 연결된 LCD 신호처리부와 보조스위치에 각각 연결된 팬구동부(19) 및 램프구동부, 파워 온 키입력시 일정시간동안 다른키가 입력되어도 상기 기기가 동작하지 않도록 하거나 파워 오프 입력시 상기 팬구동부에 전원을 공급/차단하는 보조스위치를 파워 오프후 일정시간동안 온상태로 제어하는 제어부로 구성된 것을 특징으로 한다.The projector / camcorder drive control apparatus of the present invention as described above comprises a LCD device including a LCD panel, a lamp and a cooling fan in a camcorder device having a projector function, a power supply unit for supplying power to the device, and the power supply unit. Main switch, auxiliary switch to cut off the power output from the main switch, the LCD signal processor connected to the main switch and the fan driver 19 and lamp driver connected to the auxiliary switch, respectively, when the other key is input for a certain time The control unit is configured to control the auxiliary switch to prevent the device from operating or to supply / block power to the fan driver when the power is turned off for a predetermined time after the power is turned off.
또한 본 발명의 프로젝터/캠코더 구동제어방법은 프로젝터 기능을 가진 캠코더 기기에 있어서, 프로젝터 모드 선택스텝, 프로젝터 모드 선택에 의해 램프 광량을 프로젝션 가능한 밝기로 높이는 램프광량증대스텝, 프로젝터 모드 선택후 다른 키입력시 미리 지정된 기준설정시간과 프로젝터 모드 선택시간을 비교하는 비교스텝, 상기 비교스텝에서 기준설정시간동안 키동작을 정지하게 제어하는 제어스텝으로 구성된다.In addition, the projector / camcorder driving control method of the present invention, in the camcorder device having a projector function, the step of increasing the lamp light to the projectable brightness by selecting the projector mode selection step, the projector mode, the other key input after selecting the projector mode And a comparison step of comparing the predetermined reference setting time with the projector mode selection time, and a control step of controlling the key operation to be stopped during the reference setting time in the comparison step.
