本发明涉及图像显示领域,更具体地,涉及一种屏幕显示的控制方法及电子设备。
目前,多个面积较小的屏幕可以拼接构成一个面积较大的屏幕,为了在面积较大的屏幕上输出显示一个或多个任意大小的显示窗口,面积较小的屏幕需要对输入的图像信号进行相应的处理。当输出的显示窗口被调整时,屏幕会对输出显示的图像和图像对应的配置参数即时进行调整,以使屏幕上输出的显示窗口的内容和大小发生变化。
然而,在实践中发现,当输出的显示窗口被调整时,屏幕的帧率转换模块中预先缓存的若干帧图像在被读出之后,才能缓存显示窗口被调整之后的调整图像,而配置参数却是即时发生变化的,因此,为了避免因输出的图像与配置参数不匹配导致屏幕出现花屏的现象,通常会将帧率转换模块的读指针进行冻结,以使通过读指针从帧率转换模块读出的读出帧不发生变化,但是由于读指针被冻结,屏幕输出显示的图像会出现静止的情况,导致对于屏幕输出的显示窗口的调整不够流畅。

本发明实施例中,帧缓存模块可以存在若干个缓存区,帧缓存模块可以用于缓存从图像信号中获取的缓存帧,参数缓存模块也可以存在若干个缓存区,且参数缓存模块可以用于缓存从显示窗口调整指令中获取的缓存调整参数,且帧缓存模块中的缓存区的数量需要与参数缓存模块中的缓存区的数量相同,此时,帧缓存模块中的缓存区的缓存标识才能够与参数缓存模块中的缓存区的缓存标识一一对应,且电子设备可以存储帧缓存模块中的缓存区的缓存标识与参数缓存模块中的缓存区的缓存标识的对应关系,以使电子设备可以根据任意一个帧缓存模块中的缓存区的缓存标识确 定出对应的参数缓存模块中的缓存区的缓存标识,也可以根据任意一个参数缓存模块中的缓存区的缓存标识确定出对应的帧缓存模块中的缓存区的缓存标识。
103、当缓存帧存储至帧缓存模块中与第一缓存标识对应的缓存区时,电子设备将缓存调整参数存储至参数缓存模块中与第二缓存标识对应的缓存区,并从帧缓存模块中读取待输出缓存帧,以及从参数缓存模块中读取与待输出缓存帧对应的待输出缓存调整参数。
本发明实施例中,电子设备可以在同一时间将缓存帧存储至帧缓存模块中与第一缓存标识对应的缓存区,并且将缓存调整参数存储至参数缓存模块中与第二缓存标识对应的缓存区,以避免出现与第一缓存标识对应的第二缓存标识的缓存区被其他数据预先存储的情况,也避免出现与第二缓存标识对应的第一缓存标识的缓存区被其他数据预先存储的情况。电子设备在存储缓存帧和缓存调整参数的情况下,也可以在同一时间从帧缓存模块中与第三缓存标识对应的缓存区中读取待输出缓存帧,并且从参数缓存模块中与第四缓存标识对应的缓存区中读取待输出缓存调整参数。
104、电子设备通过电子设备的屏幕输出基于待输出缓存调整参数的待输出缓存帧。
本发明实施例中,由于读取的待输出缓存调整参数和待输出缓存帧为对应的数据,因此电子设备可以通过待输出缓存调整参数对待输出缓存帧进行调整,从而得到需要在电子设备的屏幕上输出显示的目标缓存帧,从而保证了电子设备的屏幕输出的显示窗口对应的图像的稳定性。

实施例2
如图2所示,本发明实施例公开的另一种屏幕显示的控制方法可以包括以下步骤:
201、当检测到输入的显示窗口调整指令时,电子设备根据显示窗口调整指令确定缓存调整参数,并从输入的图像信号中获取缓存帧。
本发明实施例中,电子设备可以包括参数缓存模块和帧缓存模块,还 可以包括帧率转换模块和参数控制模块。
作为一种可选的实施方式,当检测到输入的显示窗口调整指令时,电子设备根据显示窗口调整指令确定缓存调整参数,并从输入的图像信号中获取缓存帧的方式可以包含以下步骤:
当检测到输入的显示窗口调整指令时,电子设备根据显示窗口调整指令确定缓存调整参数,并从输入的图像信号中获取初始帧;
电子设备获取剪切参数和缩小参数;
电子设备基于剪切参数和缩小参数对初始帧进行调整,得到缓存帧。
其中,实施这种实施方式,可以从输入的图像信号中获取到需要缓存的初始帧,并且可以通过剪切参数和缩小参数对该初始帧进行调整,以使调整后的缓存帧可以快速存储至帧缓存模块中。
本发明实施例中,为了快速将显示窗口对应的图像的缓存帧存储至帧缓存模块中,可以预先对图像信号中包含的初始帧进行处理,如可以对初始帧进行剪切和缩小调整,从而得到缓存帧,可见得到的缓存帧相对于初始帧来说占用的帧缓存模块中的内存较少,从而提高了帧缓存模块的存储性能。
202、电子设备确定缓存帧在帧缓存模块中对应的第一缓存标识,并确定参数缓存模块中与第一缓存标识对应的第二缓存标识。
203、当帧率转换模块将缓存帧存储至帧缓存模块中与第一缓存标识对应的缓存区时,电子设备控制参数控制模块将缓存调整参数存储至参数缓存模块中与第二缓存标识对应的缓存区。
本发明实施例中,参数缓存模块中的缓存区与帧缓存模块中的缓存区一一对应,可以确定参数缓存模块中的缓存区的缓存标识与帧缓存模块中的缓存区的标识一一对应,进而可以在存储缓存帧和缓存调整参数以及读取待输出缓存帧和待输出缓存调整参数时,避免出现缓存帧和缓存调整参数存储不对应以及待输出缓存帧和待输出缓存调整参数读取不对应的情况,提高了读取待输出缓存帧对应的待输出缓存调整参数的准确性。
204、电子设备通过帧率转换模块从帧缓存模块中读取待输出缓存帧,并确定待输出缓存帧在帧缓存模块中的第三缓存标识。
本发明实施例中,电子设备从帧缓存模块中读取待输出缓存帧与存储 至帧缓存模块中的缓存帧可以为不同的缓存帧,因此待输出缓存帧对应的缓存区的缓存标识与缓存帧对应的缓存区的缓存标识不相同,即第三缓存标识与第一缓存标识可以为不同的缓存标识。
205、电子设备通过参数控制模块确定参数缓存模块中与第三缓存标识对应的第四缓存标识。
本发明实施例中,由于第三缓存标识与第一缓存标识可以为不同的缓存标识,因此与第三缓存标识对应的第四缓存标识也可以为与第二缓存标识不同的缓存标识。

本发明实施例中,实施上述的步骤203~步骤206,可以通过帧率转换模块获取到存储缓存帧的缓存区的第一缓存标识,进而可以通过参数控制模块确定出与第一缓存标识匹配的第二缓存标识,进而可以将缓存调整参数存储至参数缓存模块中以第二缓存标识匹配的缓存区中,进而可以从帧缓存模块中读取待输出缓存帧,以及从参数缓存模块中读取待输出缓存调整参数,由于读取的待输出缓存帧和待输出缓存调整参数是对应读取的,因此待输出缓存调整参数与待输出缓存帧也是对应的,基于待输出缓存调整参数调整的待输出缓存帧在输出时不会导致屏幕出现花屏的现象,提高了屏幕输出显示的稳定性。
207、电子设备通过电子设备的屏幕输出基于待输出缓存调整参数的待输出缓存帧。
作为一种可选的实施方式,电子设备通过电子设备的屏幕输出基于待输出缓存调整参数的待输出缓存帧的方式可以包含以下步骤:
