Description

投影仪自适应调整方法、装置及计算机存储介质 技术领域
本发明涉及计算机领域,特别是涉及一种投影仪自适应调整方法、装置及计算机存储介质。
背景技术
在现有技术中,智能微型投影产品也可以成为智能微型投影机,是指新增了无线保真(Wireless Fidelity,简称为WIFI)上网功能并搭载了智能操作系统的投影机,安卓(Android)系统是目前运用到这一系列产品中较为广泛的智能操作系统。支持多屏互动,可以与安卓手机、安卓平板电脑(Pad)、苹果手机(iPhone)、苹果平板电脑(iPad)等互联共享;支持一键热点无线访问节点(Access Point,简称为AP)及WIFI直连(Direct);其具有多USB接口,支持USB键盘和鼠标等;并且具有体积小、易操作、多功能、多支持、便携带等特点。目前,智能投影的技术也在不断的进步,功能也将不断的完善。
投影效果的亮度调节涉及到图像亮度、投影亮度两个方面。现有的投影产品的投影亮度是通过调整投影仪中发光的发光二极管(Light Emitting Diode,LED)灯的电流,进而调节功率,从而使亮度发生变化。然而如果调大功率,势必增加功耗,减少电池的续航时间;如果调小功率,可减少功耗,然而又可能会导致图像显示不清。目前的投影产品大都采用手动调节的方式或根据光感自动调节的方式进行。手动调节,往往麻烦,费时费力;而根据光感进行自动调节,在特定的环境下亮度则是一定的,没有什么大的用处。
此外,在特定场景下,如何能够自动调节屏幕的亮度,如何使用户能 够看到更清晰的图像是亟需解决的问题。在投影仪使用过程中,用户根据实际画面的不同会有些具体要求,有些画面如果比较暗,用户更希望亮一些,更清晰一些,可以清楚地看到一些细节,例如,公安刑侦时在暗处拍到一系列较暗的图像时;而有些画面用户则希望暗一些,如果画面本身很亮,投影仪本身的亮度在当前场景下也比较亮,这时用户看画面时眼睛就会有所不适;还有时候画面虽然亮暗适中,但整个画面亮度平均,无法清晰区分各个物体,这时就需要对对比度进行调节等等。
但是,现有投影仪无法对对比度进行调节,如果投影仪能够对亮度或对比度等信息均可进行自适应调节,让过亮的暗一点,让过暗的亮一点,同时又能提高图像的对比度、清晰度,提高画面质量,这样就能达到更好的用户体验。

为了解决现有技术中无法对投影仪的亮度和对比度均进行调节、以及 投影仪根据光感进行自动亮度调节或手动亮度调节而导致的投影产品在使用过程中投影效果较差、无法清晰显示、操作繁琐的问题,本发明提供了一种投影仪自适应调整方法、装置及计算机存储介质,可以从投影亮度、图像亮度、图像对比度三个方面进行选择并自适应调节。以下结合附图以及实施例,对本发明进行进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不限定本发明。
方法实施例
根据本发明的实施例,提供了一种投影仪自适应调整方法,图1是本发明实施例提供的投影仪自适应调整方法的流程图,如图1所示,本发明实施例的投影仪自适应调整方法主要包括如下处理:
步骤101:在用户选择进行亮度调节时,获取当前画面的亮度平均值,并计算亮度平均值与预先设置的正常亮度平均值之差的绝对值。
优选地,在本发明实施例中,在步骤101之前,还可以进行如下处理:
根据用户的操作打开投影仪的自适应调整功能,并向用户提示选择进行亮度调节和/或对比度调节;
在用户选择进行亮度调节和对比度调节时,在进行投影仪的亮度调节后,进行投影仪的对比度调节;
在用户选择仅进行对比度调节时,直接进行投影仪的对比度调节。
步骤102:如果绝对值大于或等于第一预设阈值,则同时对投影亮度和图像本身亮度进行调整;如果绝对值大于或等于第二预设阈值且小于第一预设阈值,则仅对投影亮度继续调整,如果绝对值大于或等于第三预设阈值且小于第二预设阈值,则仅对图像本身亮度进行调整,如果绝对值小于第三预设阈值,则禁止进行亮度调节。
在步骤102中,对投影亮度和/或图像本身亮度进行调整具体包括:
在亮度平均值与预先设置的正常亮度平均值之间的差值为正时,确认 亮度过高,进行调暗操作;
在亮度平均值与预先设置的正常亮度平均值之间的差值为负时,确认亮度过暗,进行调亮操作。
这里,具体如何进行调暗操作、调亮操作以及调整的幅度可根据实际情况进行调节。
步骤103:将自适应调整后的画面数据发送到投影模块进行投影。
以下结合附图,对本发明实施例的上述技术方案进行详细说明。
当用户使用投影仪进行投影时,可根据其应用场景在设置模块选择是否需要打开图像处理功能(即,上述自适应调整功能);如果用户没有事先进行设定,当用户开始使用投影仪时,设置模块可提示用户是否需要打开此功能;如果用户不选择此功能,选No选项,并关闭对话框;如果用户选择打开该功能时,可进一步选择需要进行图像的亮度调节、对比度调节、或两者均要进行调节;如果用户选择打开该功能时,画面数据在转为高清晰度多媒体接口(High Definition Multimedia Interface,HDMI)信号之前进行相应的自适应调整工作。
图2是本发明实施例提供的投影仪自适应调整方法的结构示意图,如图2所示,该投影仪自适应调整方法的结构示意图包括投影画面数据采集模块20、投影画面处理模块21、以及投影模块22,其中,所述影画面数据采集模块20主要用于对投影画面的数据进行采集,所述投影画面处理模块21将采集的数据进行自适应调整,随后画面数据转为HDMI信号发送给所述投影模块22进行投影。下面对投影画面处理模块21将采集的数据进行自适应调整的处理进行详细说明。
具体地,当用户选择进行亮度调节时,设置正常平均亮度值为A,并设置阈值X1、X2、X3(对应于上述第一预设阈值、第二预设阈值、以及第三预设阈值)。当所述投影画面处理模块21检测到当前画面的平均亮度 值与A之差的绝对值大于或等于X1时,此时认为当前画面过暗,此时会同时对投影亮度和图像本身亮度进行调整,先调整投影亮度,随后调整图像亮度;当该差值为正时,认为亮度过高,则需进行调暗的操作;如果差值为负,认为亮度过暗,需进行调亮操作;
如果检测到当前画面的平均亮度值与A之差的绝对值大于或等于X2且小于X1时,则只需要调整投影亮度;同样,当该差值为正时,认为亮度过高,则需进行调暗的操作;如果差值为负,认为亮度过暗,需进行调亮操作;
如果检测到当前画面的平均亮度值与A之差的绝对值大于或等于X3且小于X2时,则只需简单通过调整图像亮度来进行微调;同样,当该差值为正时,认为亮度过高,则需进行调暗的操作;如果差值为负,认为亮度过暗,需进行调亮操作;
如果检测到当前画面的平均亮度值与A之差的绝对值小于X3时,则不进行调节。
当用户选择需进行对比度调节时,则在保持当前画面亮度不变的情况下调节对比度,以使得画面质量更加清晰分明。
本发明实施例的技术方案,采用先调节亮度,再调节对比度的方法进行。
在实际应用中,用户在Sink应用中选择了开启投影功能;Sink应用首先检查所述投影模块22是否开启,如果没开启的话则开启它;当所述投影模块22开启后,Sink应用告知系统目前处于投影模式;,Sink应用弹出设置菜单,由用户选择是否需要进行投影前的自适应处理,包括进行亮度处理和对比度处理两个选项。并在用户选择后关闭;如果用户选择了要进行亮度处理,则Sink应用会将底层读取缓冲区(Buffer)中的数据进行图像处理操作。根据图像处理所得结果,对投影仪的发光LED电流进行调整, 或对原画面的图像进行亮度调整;如果用户选择了要进行对比度调整,则Sink应用会将亮度处理后的数据做进一步的对比度处理;处理后的数据转换为HDMI信号发送到投影模块,完成画面的清晰显示。
图3是本发明实施例提供的投影仪自适应调整方法的详细处理的流程图,如图3所示,该流程主要包括如下处理:
步骤301,判断用户是否选择需要进行投影效果调节,如果判断为是,执行步骤302,否则结束操作;
步骤302,判断用户是否选择画面亮度调节,如果判断为是,执行步骤303,否则,执行步骤310;
步骤303,计算投影画面数据的亮度平均值与正常亮度平均值A的差值Δ;
步骤304,判断|Δ|≥X1是否成立,如果成立,执行步骤312,否则,执行步骤305;
步骤305,判断X1﹥|Δ|≥X2是否成立,如果成立,执行步骤317,否则,执行步骤306;
步骤306,判断X2﹥|Δ|≥X3是否成立,如果成立,执行步骤307,否则,执行步骤310;
步骤307,判断Δ﹥0是否成立,如果成立,执行步骤308,否则,执行步骤309;
步骤308,调低画面亮度;
步骤309,调高画面亮度;
步骤310,判断用户是否选择进行画面对比度的调节,如果判断为是,执行步骤311,否则,结束操作;
步骤311,调节画面对比度,结束操作;
步骤312,判断Δ﹥0是否成立,如果成立,执行步骤315,否则,执 行步骤313;
步骤313,调高投影亮度;
步骤314,调高画面亮度,执行步骤310;
步骤315,调低投影亮度;
步骤316,调低画面亮度,执行步骤310;
步骤317,判断Δ﹥0是否成立,如果成立,执行步骤318,否则,执行步骤319;
步骤318,调低投影亮度,执行步骤310;
步骤319,调高投影亮度,执行步骤310。
