Description

图像质量调整方法及系统 技术领域
本申请涉及视频设备领域,具体涉及一种图像质量调整方法及系统。
背景技术
使用视频设备观看影片或电视节目已经成为现代人获取新知识或新信息的方式之一,也可以用来做为休闲娱乐的一种方式。在观看影片或电视节目时,使用者通常会根据使用习惯及视频内容来调整合适的图像质量,以增加临场感、视觉效果或是降低对眼睛的负担。例如,在观看电影时,可以将图像质量调整为剧院模式,来达到在电影院观看影片的视觉享受;或是认为视频内容的图像亮度过于强烈,则降低图像质量中的亮度参数。前述的情况中,使用者虽然可以主动通过视频设备的用户界面将图像质量调整为需要的视频模式,以获取相对应的视觉效果,但是这种调整方式往往造成一些问题产生。
举例而言,在不同的需求以及不同的时间状态下使用视频设备时,当视频设备开机时所采用的图像质量,通常都是相同于前次关闭视频设备时的图像质量。例如,可能前次是在图像质量为电影模式的状态下观看电影,并且视频设备在此模式状态下关机。当下次再开启视频设备时,则会以相同的图像质量来播放影片或是电视节目。因此,若是要根据不同视频内容的类型来调整视频模式时,就必须再次调整视频设备的图像质量以符合使用者的需求,所以在使用上相当不便。
另外,视频设备基于外在环境的不同或是使用者的习惯不同,时常要对不同视频内容的图像质量进行调整,例如,在光线不足的情况下,对应降低图像质量的亮度,来减轻使用者眼睛的负担;或是在经过白天的工作后,眼睛已经较为疲劳,此时观看视频内容的需求可能只是做为休闲娱乐,而对应降低图像质量的亮度,来减轻使用者眼睛的负担等。但是,这些调整操作仍然需要通过使用者主动的操作进行,因此产生了使用上的不方便。
发明内容
本申请的目的在于提供一种图像质量调整方法及系统,用以解决图像质量参数必须以人工方式随着视频设备的使用状态及视频内容往复调整,所带来使用不便的问题。
为达到上述目的,本申请实施例采用如下技术方案:
第一方面,一种图像质量调整方法,适用于视频设备。图像质量调整方法包括:获取视频设备显示视频的当前时间,判断当前时间是否落入预定时间段,若否,调用图像质量参数的默认值,若是,执行图像质量调整程序。图像质量调整程序包括:检测环境光的亮度值;根据亮度值调用相应的图像质量参数的设定值;判断当前视频内容的类型,并且根据视频内容的类型获取相应的图像质量参数的参考值;以及比对图像质量参数的设定值与图像质量参数的参考值,若图像质量参数的设定值大于图像质量参数的参考值,将图像质量参数的设定值调降至图像质量参数的参考值,若图像质量参数的设定值等于或小于图像质量参数的参考值,持续调用图像质量参数的设定值。
第二方面,一种图像质量调整系统,适用于视频设备。图像质量调整系统包括光传感器、定时器以及处理器。光传感器用以侦测环境光的亮度值。定时器用以侦测视频设备操作时的当前时间,并且设置有预定时间段。处理器电性连接于光传感器与定时器,处理器根据当前时间与预定时间段,判断是否执行图像质量调整程序,并且在图像质量调整程序中,根据亮度值调用相应的图像质量参数的设定值;以及根据视频设备所播放的视频内容获取相应的图像质量参数的参考值来决定是否调整图像质量参数的设定值。
与现有技术相比,本申请可以获得包括以下技术效果:
首先,本申请的图像质量调整方法及系统,通过处理器判断当前时间是否落入预定时间段的结果来进行是否执行图像质量调整程序,增加了应用上的弹性,从而可依据使用需求来选择是否执行图像质量调整程序,以及从哪个时间点开始执行。
再者,本申请的图像质量调整方法及系统在进行调整图像质量的操作中,根据亮度值调用相应的图像质量参数的设定值以及根据视频内容的类型获取相应的图像质量参数的参考值,并且通过处理器比对设定值与参考值, 再根据比对结果进一步地调整图像质量参数,从而提供高质量的视频内容观赏环境,并且减少了人为的手动操作程序,大幅提升使用上的便利性与实用性。

步骤230,若是,执行图像质量调整程序。
如图4所示,图像质量调整程序包括:
步骤231,检测环境光的亮度值;
步骤232,根据亮度值调用相应的图像质量参数的设定值;
步骤233,判断当前视频内容的类型,并且根据视频内容的类型获取相应的图像质量参数的参考值;
步骤234,比对图像质量参数的设定值与图像质量参数的参考值;
步骤235,若图像质量参数的设定值大于图像质量参数的参考值,将图像质量参数的设定值调降至图像质量参数的参考值;以及
步骤236,若图像质量参数的设定值等于或小于图像质量参数的参考值,持续调用原图像质量参数的设定值。
请参照图1至图4,在本方法实施例中,视频设备显示视频时,例如当视频设备开机时或者是播放视频内容一段时间后,通过图像质量调整系统100的定时器120侦测当前时间,例如视频设备的开机时间,并且将所获取的当前时间传送至处理器130,接着通过处理器130在预定时间段中比对当前时间,从而判断当前时间是否落入预定时间段内(步骤210)。其中,预定时间段可以设置为24小时,或者是其中的某个特定时间区间,又或者是其中的几个时间区间,例如是晚上6点到隔天早上6点,或者是晚上6点至12 点以及早上5点至7点等。在本实施例中,以预定时间段为晚上6点到隔天早上6点作为举例说明,但并不以此为限。
因此,当视频设备的开机时间是在早上十点,则处理器130判断当前时间未落入预定时间的范围内,因此不符合图像质量调整程序的启动条件,处理器130即调用视频设备中已设定好的图像质量参数的默认值,作为播放当前视频内容的图像质量参数值来呈现画面(步骤220)。反之,若开机时间是在晚上8点,处理器130即判断当前时间落入预定时间内,而对应执行图像质量调整程序(步骤230)。
在图像质量调整程序中,首先,通过光传感器110检测环境光的亮度值(步骤231),然后通过处理器130接收亮度值,并且根据亮度值调用相应的图像质量参数的设定值(步骤232),其中图像质量参数包括但并不局限于亮度参数、对比度参数、色彩饱和度参数、色温参数或上述参数的组合等,为了方便说明,本实施例以图像质量参数为亮度参数作为举例说明,但并不以此为限。
承上,在处理器根据亮度值调用相应的图像质量参数的设定值的操作中,假设以亮度参数为55%作为设定值。接着,再通过处理器130判断当前视频内容的类型,并且根据视频内容的类型获取相应的图像质量参数的参考值(步骤233)。一般视频内容的类型可以区分为电影、一般节目、电视剧及其他,并且这些类型的视频内容都预先设定有相应的图像质量参数的参考值,例如当视频内容为电影时,以亮度参数为40%作为参考值;当视频内容为一般节目时,以亮度参数为50%作为参考值;以及当视频内容为电视剧时,以亮度参数为46%作为参考值。并且,这些参考值可以是图像质量参数在这些视频内容播放时所能调整的最大值,从而预先设置调整门坎,用以避免图像质量参数过大而降低视频质量。
在处理器130根据视频内容的类型调用相应的图像质量参数的参考值之后,处理器130接着比对设定值与参考值(步骤234),并且根据比对结果判断是否进一步对图像质量参数进行调整。若比对结果为设定值大于参考值,处理器130将设定值调降至参考值,让视频内容在当前的操作环境下,可以优化的图像质量参数进行播放,同时能提供舒适的视觉感受(步骤235)。反之, 若比对结果为设定值等于或小于参考值,表示当前所采用的图像质量参数的设定值已达到符合当前播放环境的使用需求,因此处理器130不动作,也就不再对图像质量参数进行调整(步骤236)。
换言之,如果当前播放的视频内容的类型是电影或是一般节目,那么处理器130会将原本亮度参数为55%的设定值分别调降至40%或50%。反之,如果当前播放的视频内容的类型是电视剧,那么处理器130就会维持原本亮度参数为55%的设定值。
基于上述,本申请的图像质量调整系统及其方法,通过处理器130根据当前时间、环境光的亮度值以及当前视频内容的类型,主动的将图像质量参数调整至适于视频内容在当前的环境下播放,而达到优化的参数设定,从而增加了使用上的方便性与实用性。另外,值得说明的是,本申请中所述的图像质量参数并不以上述示范的参数类型为限。
如图5所示,是本申请第二方法实施例的图像质量调整方法流程图。在本申请第二方法实施例中,其步骤310、320、330分别类似于第一方法实施例中的步骤210、220、230,故不再赘述。而两者间的差异在于,本申请第二方法实施例所揭露的图像质量调整方法,在判断当前时间是否落入预定时间段的操作中,当判断当前时间未落入预定时段,而调用图像质量参数的默认值的操作之后,还包括:
步骤321,获取视频内容的当前播放时间;
步骤322,判断当前播放时间是否落入预定时间段内,若是,执行图像质量调整程序;以及
步骤323,若否,持续调用原图像质量参数的设定值。
请参照图1和图5,在本方法实施例中,通过定时器120获取视频内容的当前播放时间。之后,通过处理器130判断当前播放时间是否落入预设时间段内。若是,处理器130即执行图像质量调整程序;若否,处理器130不动作,使视频内容维持以原先的图像质量参数的设定值进行播放。本实施例的目的之一是让视频设备在播放视频内容一段时间后,也能适用本申请的图像质量调整方法,来增加使用上的方便性与弹性。例如,一开始视频设备在开机当下的时间尚未落入预定时间段,所以处理器130调用图像质量参数的 默认值来播放视频内容。但是在视频内容播放一段时间后,通过定时器120实时侦测当前播放时间(步骤321),并且将侦测结果回传至处理器130,让处理器130判断当前播放时间是否已落入预定时间段,若是,处理器130即执行图像质量调整程序的操作(步骤322),从而实现视频设备在播放视频时,仍可经由处理器130主动调整图像质量,来提供适于当前视频内容及播放时间的图像质量参数值,从而提高视频内容的图像质量,以及提供舒适的视频画面。反之,若当前播放时间仍然未落入预定时间段,处理器130即不动作,而持续以原设定值作为图像质量的参数值(步骤323)。
如图6所示,是本申请第三方法实施例的图像质量调整方法流程图。在本申请的第三方法实施例中,步骤410、420、430分别类似于第一方法实施例中的步骤310、320、330,故不再赘述。
请参照图1和图6,在本申请第三方法实施例所揭露的图像质量调整方法中,在执行图像质量调整程序的操作(步骤430)之前,还包括:
步骤411,发送提示信号;
步骤412,判断在延迟时间内是否接收到相应的反馈信号,若是,执行图像质量调整程序;以及
步骤413,若否,持续调用原图像质量参数的设定值。
在本申请第三方法实施例中,通过处理器130发送提示信号(步骤411),并且在延迟时间内等待反馈信号,若处理器130在延迟时间内未接收到反馈信号,处理器130即执行图像质量调整程序;反之,若处理器130在延迟时间内接收到反馈信号则不动作,而持续以原设定值作为图像质量的参数值。本实施例的目的之一是为了在图像质量即将被调整时起到警示作用,让使用者选择是否要执行图像质量调整程序。例如,通过显示单元接收提示信号,并且根据提示信号控制灯光闪烁或者是显示提示画面,此时,使用者在观看电视时就会注意到图像质量即将调整的提醒;或是,通过遥控器接收提示信号,并且根据提示讯号产生震动,同样可以达到提醒使用者图像质量即将调整的目的。接着,在收到提醒后,若是不希望改变目前的图像质量参数,使用者可以在延迟时间内通过遥控器或电视的选择单元来发送反馈信号,例如,在接收到图像质量将被调整的提醒后,在10秒内通过遥控器发送反馈 信号,处理单元120在接收到反馈信号后,即根据反馈信号停止执行图像质量调整程序(步骤413)。反之,若同意改变目前的图像质量时,使用者可以不理会此提示信号而继续观赏节目,并且在超过延迟时间后,处理单元120判断在延迟时间内未接收到相应的反馈信号,而自动执行图像质量调整程序(步骤412)。值得说明的是,在本实施例中所使用的提示方法,也可以类似或相同的方式适用在其它实施例中。
另外,在本申请实施例所揭示的图像质量调整方法及系统中,预定时间段、图像质量参数的设定值以及图像质量参数的参考值,可以如先前所述,预先存储在数据库中;或者是,在本申请的一些实施例中,也可以是在判断当前时间是否落入预定时间段的操作前,先完设置预定时间段;设置与环境光的亮度值相应的图像质量参数的设定值;以及设置与视频内容的类型相应的图像质量参数的参考值等步骤。让本申请的图像质量调整方法可以视实际需求弹性调整这些参数值与时间段的设置顺序。
上述说明示出并描述了本申请的若干优选实施例,但如前所述,应当理解本申请并非局限于本文所披露的形式,不应看作是对其它实施例的排除,而可用于各种其它组合、修改和环境,并能够在本文所述发明构想范围内,通过上述教导或相关领域的技术或知识进行改动。而本领域人员所进行的改动和变化不脱离本申请的精神和范围,则都应在本申请所附权利要求的保护范围内。
