Description

图像显示方法及装置和电子设备 技术领域
本说明书实施例涉及互联网技术领域，尤其涉及一种图像显示方法及装置和电子设备。
背景技术
随着互联网技术的不断发展，特别是移动终端的不断普及，通过扫描图像执行相关业务的场景越来越多，例如，扫码取票、扫码支付。在实际使用时，用户将展示有待扫描图像的终端面向扫描设备，由于终端展示的图像大小通常是固定的，而每个用户终端距离扫描设备又是不固定的，很多情况下，需要工作人员不断移动扫描设备寻找最佳的距离完成扫描。例如如果用户距离扫描设备较远，对于扫描设备来说，图像会显得很小，不容易扫描成功，需要操作扫描设备的工作人员移动扫描设备贴近终端，并寻找到最佳的距离来完成扫描；如果用户距离扫描设备较近，对于扫描设备来说，图像会显得太大，同样不容易扫描成功，需要工作人员移动扫描设备远离终端，并寻找到最佳的距离来完成扫描。
需要提供更为高效地图像显示方案来提高扫描成功率。

如前所述，在实际使用时，用户将展示有待扫描图像的终端面向扫描设备，由于终端展示的图像大小通常是固定的，而每个用户终端距离扫描设备又是不固定的，很多情况下，需要工作人员不断移动扫描设备寻找最佳的距离完成扫描。例如如果用户距离扫描设备较远，对于扫描设备来说，图像会显得很小，不容易扫描成功，需要操作扫描设备的工作人员移动扫描设备贴近终端，并寻找到最佳的距离来完成扫描；如果用户距离扫描设备较近，对于扫描设备来说，图像会显得太大，同样不容易扫描成功，需要工作人员移动扫描设备远离终端，并寻找到最佳的距离来完成扫描。
需要提供更为高效地图像显示方案来提高扫描成功率。
以下请求参考图1所示本说明书实施例中提供的实现图像显示的系统架 构图。图1所示该系统100可以包括用户的终端11、扫描设备12。
其中，终端11可以用于展示待扫描的图像111，并且所述终端11中还可以设置有检测设备112，所述检测设备112可以用于检测所述终端11距离所述扫描设备12的距离值。
扫描设备12可以用于扫描终端11展示的图像111，从而执行相关的业务流程，例如支付场景中，终端11展示的可以是支付码图像(如图1中所示)，而扫描设备12通过扫码可以完成收款流程；再例如取票场景中，终端11展示的可以是取票码图像，而扫描设备12通过扫码可以完成身份验证，从而发放票据(可以是纸质或者电子的)。
在实际使用时，用户可以在距离扫描设备12的任意位置，将展示有待扫描图像111的终端11面向扫描设备12；所述终端11基于检测设备检测到的距离值可以自动调整所展示图像111的大小(例如将原本较小的图像111放大，或者将原本较大的图像111缩小)，从而方便扫描设备12高效地进行扫描。
以下请结合图2所示的例子介绍本说明书一种实现图像显示的方法的实施例，如图2所示，该方法可以包括以下步骤：
步骤210：确定当前终端中展示的图像。
本实施例中，所述图像可以是指图形码，例如包括二维码、条形码等。
步骤220：获取检测设备检测到的所述终端距离扫描设备的距离值；所述扫描设备用于扫描所述展示的图像。

一般的，终端可以设置有距离传感器(如图3中所示)，本说明书中距离传感器可以用于检测终端距离扫描设备的距离值，并在检测出距离值后上报给终端。
距离传感器通过可以是由两个元器件组成，一个可以发射红外线，另一 个可以检测红外线。工作原理如下，发射的红外线在遇到障碍物(本说明书中所述的扫描设备)后会发生反射，反射的红外线被检测红外线的元器件检测到。根据发射红外线到检测到红外线的时间，以及红外线的速度，就可以计算出终端距离障碍物的距离值。

本说明书中，所述扫描设备可以包括手持的扫码枪或者固定的扫码器等。
步骤230：根据所述距离值，计算所述图像的最佳大小。

5米对应的最佳大小为5cm*5cm；
10对应的最佳大小为10cm*10cm；
当前，最终确定的最佳大小还需要根据终端实际屏幕大小决定，例如，计算出的最佳大小超过了终端屏幕大小的情况下，则最终确定的最佳大小可以为屏幕大小。
在另一种实现方式中，终端可以根据本地计算模型，计算出最佳大小。
所述计算模型可以是业务方服务器提供的，例如支付场景中，所述第三方服务器即为支付应用平台；在取票场景中，所述第三方服务器既可以是售票应用平台。
所述模型通常可以是基于海量距离值与最佳大小的数据训练得到的。终端将获取到的距离值输入到该计算模型，就可以得到输出的最佳大小。
步骤240：将当前展示的图像的大小调整为所述最佳大小。
用户可以在距离扫描设备的任意位置，将展示有待扫描图像的终端面向扫描设备；所述终端中的检测设备可以检测该终端距离扫描设备的距离值；然后，终端根据所述检测设备检测到的距离值，计算出该图像最方便扫描设备进行扫描的最佳大小，最后可以将展示的图像的大小调整为最佳大小；由于调整后图像的大小最方便扫描设备进行扫描，所以可以实现提高扫描成功率。

扫描设备43可以用于扫描终端41展示的图像411，从而执行相关的业务流程，例如支付场景中，终端41展示的可以是支付码图像(如图4中所示)，而扫描设备43通过扫码可以完成收款流程；再例如取票场景中，终端41展示的可以是取票码图像，而扫描设备43通过扫码可以完成身份验证，从而发 放票据(可以是纸质或者电子的)。
