Abstract
一种具有消隐显示在屏幕上的图像信息的屏幕消隐功能的图像再现装置及使用其的屏幕消隐方法。该图像再现装置包括:命令施加单元,用于施加图像消隐执行和消除代码;屏幕消隐判断单元,用于根据命令施加单元提供的代码来判断是否消隐屏幕;以及屏幕电源控制单元,用于根据屏幕消隐判断单元判断的结果来控制提供给屏幕的电源。
Description
本发明涉及一种图像再现装置,特别涉及一种具有抑制显示在屏幕上的图像信息的屏幕消隐功能的图像再现装置及使用其的屏幕消隐方法。
以下屏幕消隐指的是截断施加到图像再现装置的显示单元上的电源的功能,从而意味着当从外部施加屏幕消隐代码时,图像信息不显示在屏幕上。通常,应用于图像再现装置的消音电路由于电话呼叫等外部因素,而截断从图像再现装置输出的声音信息。
图1是应用于现有图像再现装置的消音电路的结构方框图。
图1所示的现有消音电路包括:消音判断单元10,用于当从遥控器输入消音代码信号时判断是否消音,并用于输出与其对应的控制信号;声音输出单元12,用于根据消音判断单元10提供的控制信号输出声音。
图1所示的现有消音电路的操作如下。
当施加消音执行代码时,消音判断电路10控制声音输出单元12以对声音输出进行消音。当施加消音取消代码时,消音判断单元控制声音输出单元12以输出声音。
应用于现有图像再现装置的消音电路如上所述来消音。然而,由于以下原因,有时需要屏幕消隐功能。
在脱口秀(talk shows)或音乐会表演节目中,显示在屏幕上的图像很少变化,从而使观众厌倦。此外,因节目类型而异,观众有可能只聆听音乐而不观看屏幕。在这种情况下,由于没人观看显示在屏幕上的图像,所以浪费了用来将图像信息显示在屏幕上的电能。
此外,当只将从图像再现装置输出的声音记录到录音带上时,不必观看屏幕。
因此,当根据观众的品味只聆听声音信号时,需要开发能够消隐屏幕而只输出声音的图像再现装置以避免使用不需要的电能。
本发明的一个目的是提供一种具有屏幕消隐功能的图像再现装置,通过该功能可以根据观众的品味消隐屏幕而只输出声音从而减少能耗。
本发明的另一目的是提供一种使用其的屏幕消隐方法。
为了实现上述第一个目的,提供一种具有屏幕消隐功能的图像再现装置,包括:命令施加单元,用于施加图像消隐执行和消除代码;屏幕消隐判断单元,用于根据命令施加单元提供的代码来判断是否消隐屏幕;以及屏幕电源控制单元,用于根据屏幕消隐判断单元判断的结果来控制提供给屏幕的电源。
为了实现上述第二个目的,提供一种图像再现装置的屏幕消隐方法,包括以下步骤:判断施加的代码类型;以及根据判断结果,当该代码是屏幕消隐执行代码时,控制截断施加到屏幕的电源,而当该代码是屏幕消隐取消代码时,控制将电源施加到屏幕。
通过结合附图详细描述本发明的优选实施例,本发明的上述目的和优点将会变得更加明显,其中,
图1是应用于现有图像再现装置的消音电路的结构方框图;
图2是本发明的应用于图像再现装置的屏幕消隐电路的结构方框图;
图3是描述本发明的屏幕消隐方法的流程图。
图2是本发明的应用于图像再现装置的屏幕消隐电路的结构方框图。
图2所示的屏幕消隐电路包括:命令施加单元20;屏幕消隐判断单元22;屏幕电源控制单元24;消音判断单元26;以及声音输出单元28。
命令施加单元20施加屏幕消隐和消音执行/取消代码。屏幕消隐判断单元22根据命令施加单元20提供的代码,判断是否消隐屏幕。屏幕电源控制单元22根据屏幕消隐判断单元20判断的结果,控制施加到屏幕的电源。消音判断单元26根据命令施加单元20提供的消音代码和屏幕消隐判断单元22提供的判断结果,判断是否消音。声音输出单元28根据消音判断单元26判断的结果控制声音输出。
图2所示的装置的操作如下。
屏幕消隐判断单元22判断命令施加单元20是否施加屏幕消隐执行代码。当施加屏幕消隐执行代码时,屏幕消隐判断单元22将消音控制信号输出到屏幕电源控制单元24,以便屏幕电源控制单元24截断施加到屏幕的电源。当命令施加单元20施加屏幕消隐取消代码时,屏幕消隐判断单元22将取消控制信号输出到屏幕电源控制单元24,以便屏幕电源控制单元24向屏幕提供电源。
在本实施例中,当屏幕消隐判断单元22控制截断由屏幕电源控制单元24提供给屏幕的电源时,即使命令施加单元20施加消音代码,消音判断单元26也控制从声音输出单元28输出声音。
此外,命令施加单元200施加的屏幕消隐或消音代码信号被分成消隐或消音执行代码和消隐或消音取消代码。消隐消音判断单元22和26将用于消隐或消音执行代码的键输入识别为消隐消音执行代码,而将另一键输入识别为消隐或消音取消代码。
图3是描述本发明的屏幕消隐方法的流程图。
首先,施加命令(步骤30)。
判断在步骤30中施加的命令是否是屏幕消隐代码(步骤32)。
如果根据步骤32的判断结果判定该代码不是屏幕消隐代码,则根据相关命令执行操作。这里,由于相关命令的执行与本发明无关,所以省略对其的详细描述。
当根据步骤32的判断结果判定该命令是屏幕消隐代码时,判断该屏幕消隐代码是否是屏幕消隐执行代码(步骤36)。
当根据步骤36的判断结果判定该屏幕消隐代码是屏幕消隐执行代码时,截断提供给屏幕的电源(步骤38)。当该屏幕消隐代码是屏幕消隐取消代码时,向屏幕提供电源(步骤40)。
上述本发明可以应用于各种图像再现装置。
如上所述,可以根据本发明在具有屏幕消隐功能的图像再现装置中节约提供给屏幕的电能。此外,该图像再现装置具有简单的结构。
