请参照图示，其中相同的组件符号代表相同的组件，本申请的原理是以实施在一适当的运算环境中来举例说明。以下的说明是基于所例示的本申请具体实施例，其不应被视为限制本申请未在此详述的其它具体实施例。
请参阅图1，图1为本申请实施例提供的用户界面海报图片的处理方法的第一种流程示意图。该用户界面海报图片的处理方法的流程可以包括：
在101中，获取待显示于电子设备用户界面的预设位置的第一图片。
目前电子设备用户界面需要多个用户界面海报图片配合显示。其中，电子设备用户界面海报图片处理流程可以包括：先对图片素材进行设计，并输出到图像库；然后对图像库中的图片直接进行格式压缩、缩小处理；再将处理后的图片部署到用户界面上相应的位置。但是，相关技术中，有些用户界面海报图片在电子设备用户界面上显示不清晰。
可以理解的，在电子设备用户界面中，不同的预设位置需要对应不同的用户界面海报图片配合显示，因此根据不同预设位置的显示需要，需要获取不同的用户界面海报图片用于显示。
本申请实施例中，首先，需要获取待显示于电子设备用户界面的预设位置的第一图片，第一图片可以作为初始图片，用于后续处理得到所需要的用户界面海报图片。
在一种实施方式中，可以根据具体的用户界面的显示需求，设计得到第一图片。其中，在对第一图片进行设计时，可以对设计质量进行规范化要求，比如要求设计的第一图片的图片分辨率、图片清晰度等需符合规范化要求。具体的，可以分析所需的用户界面海报图片的设计需求，比如根据用户界面海报图片的部署位置、尺寸大小等信息，确定所需的用户界面海报图片的分辨率大小，再根据设计需求和设计素材，设计出第一图片，避免由于设计不规范导致获取不符合显示需求的初始图片。需要说明的是，本申请实施例不对第一图片的具体获取方式进行限制，比如还可以从云端获取第一图片。
在102中，当第一图片的清晰度大于清晰度阈值时，则对第一图片进行清晰度处理以得到第二图片，清晰度处理包括锐化处理。
本申请实施例中，获取到第一图片后，会对第一图片根据清晰度进行选择，可以理解的，选择足够清晰的第一图片作为初始图片，可以方便后续跟据该初始图片得到清晰度较好的用户界面海报图片，防止选择清晰度不足的第一图片，导致后续跟据该第一图片无法得到足够清晰的用户界面海报图片。
因此，为了选择足够清晰的第一图片，本申请实施例会判断获取的第一图片的清晰度是否大于清晰度阈值。
在一种实施方式中，可以获取第一图片的边缘清晰程度值；判断边缘清晰程度值是否大于清晰度阈值。可以理解的，一张图片的边缘区域比起图片的非边缘区域更容易发生变形、或更容易产生锯齿等现象，因此图片的边缘区域比起图片的非边缘区域更容易存在不清晰的现象，所以如果第一图片的边缘清晰度值大于清晰度阈值，则可以说明该第一图片整体都具有足够的清晰度。
需要说明的是，清晰度阈值可以根据具体的用户界面海报图片的设计需求设置，使得用户界面海报图片在用户界面上至少能够基本清晰的显示，本申请对清晰度阈值不作限制。
本申请实施例中，若第一图片的清晰度大于清晰度阈值，则对第一图片进行清晰度处理，以得到第二图片。其中，清晰度处理包括锐化处理，可以理解的，若第一图片具有较好的清晰度，则继续对第一图片进行锐化处理，锐化处理可以增强第一图片的边缘及灰度跳变的部分，有助于眼睛清楚看到第一图片中的细节，从而使锐化处理后得到的第二图片显得棱角分明、画面更加清晰，从而得到清晰度更好的第二图片。
需要说明的是，本申请实施例中的清晰度处理，除了包括锐化处理以外，还可以包括对图片的其它处理，比如对图片的亮度、对比度、曲线、色阶、饱和度等参数进行调整，以使清晰度处理后得到的第二图片具有更好的清晰度。
需要说明的是当第一图片的清晰度小于清晰度阈值时，则执行获取待显示于电子设备用户界面的预设位置的第一图片的步骤，直至获取到清晰度大于清晰度阈值的第一图片。
在103中，将第二图片设置在电子设备用户界面位置。
可以理解的，由于第二图片具有更好的清晰度，将第二图片作为用户界面海报图片设置在对应的用户界面的预设位置，用户界面海报图片在对应的用户界面的预设位置将更加清晰的显示。
在一种实施方式中，为了确保第二图片的清晰度，可以在将第二图片设置在电子设备用户界面的预设位置之前，对第二图片进行再次进行清晰度的判断，具体的，可以获取第二图片的第二清晰度；若第二清晰度大于目标清晰度，则将第二图片设置在电子设备用户界面的预设位置。需要说明的是，目标清晰度也可以根据具体的用户界面海报图片的设计需求设置，使得用户界面海报图片在用户界面上可以呈现比较清晰的显示，目标清晰度值可以大于或等于清晰度阈值，本申请对目标清晰度不作限制。
在本申请实施例中，首先判断获取的待显示于电子设备用户界面的预设位置的第一图片的清晰度是否大于清晰度阈值，选择足够清晰的第一图片，从而后续可以跟据该第一图片得到清晰度较好的用户界面海报图片，防止选择清晰度不足的第一图片，导致后续跟据该第一图片无法得到足够清晰的用户界面海报图片。若第一图片的清晰度大于清晰度阈值，则对第一图片进行清晰度处理，清晰度处理包括锐化处理，以得到清晰度处理后的第二图片。若第一图片具有较好的清晰度，则继续对第一图片进行清晰度处理，以进一步提高其清晰度，从而得到清晰度更好的第二图片，再将第二图片设置在电子设备用户界面的预设位置。可以理解的，将第二图片作为用户界面海报图片设置在对应的用户界面的预设位置，由于第二图片整体具有较好的清晰度，从而大幅提高用户界面海报图片在用户界面上的清晰度。
请参阅图2，图2为本申请实施例提供的用户界面海报图片的处理方法的另一流程示意图，流程可以包括：
在201中，获取待显示于电子设备用户界面的预设位置的第一图片。
在电子设备用户界面中，不同的预设位置需要对应不同的用户界面海报图片配合显示，因此根据不同预设位置的显示需要，需要获取不同的用户界面海报图片用于显示。
本申请实施例中，首先，需要获取待显示于电子设备用户界面的预设位置的第一图片，第一图片可以作为初始图片，用于后续处理得到所需要的用户界面海报图片。
在一种实施方式中，可以根据具体的用户界面的显示需求，设计得到第一图片。其中，在对第一图片进行设计时，可以对设计质量进行规范化要求，比如要求设计的第一图片的图片分辨率、图片清晰度等需符合规范化要求。具体的，可以分析所需的用户界面海报图片的设计需求，比如根据用户界面海报图片的部署位置、尺寸大小等信息，确定所需的用户界面海报图片的分辨率大小，再根据设计需求和设计素材，设计出第一图片，避免由于设计不规范导致获取不符合显示需求的初始图片。并将设计出的第一图片的分辨率、用户界面中所需部署的位置等信息保存到第一图片的元数据（Metadata），将第一图片输出到图片库中以待清晰度处理。
需要说明的是，本申请实施例不对第一图片的具体获取方式进行限制，比如还可以从云端获取第一图片。
在202中，当第一图片的清晰度大于清晰度阈值时，获取第一图片的图片格式。
本申请实施例中，获取到第一图片后，会对第一图片根据清晰度进行选择，可以理解的，选择足够清晰的第一图片作为初始图片，可以方便后续跟据该初始图片得到清晰度较好的用户界面海报图片，防止选择清晰度不足的第一图片，导致后续跟据该第一图片无法得到足够清晰的用户界面海报图片。
因此，为了选择足够清晰的第一图片，本申请实施例会判断获取的第一图片的清晰度是否大于清晰度阈值。
在一种实施方式中，可以获取第一图片的边缘清晰程度值；判断边缘清晰程度值是否大于清晰度阈值。可以理解的，一张图片的边缘区域比起图片的非边缘区域更容易发生变形、或更容易产生锯齿等现象，因此图片的边缘区域比起图片的非边缘区域更容易存在不清晰的现象，所以如果第一图片的边缘清晰度值大于清晰度阈值，则可以说明该第一图片整体都具有足够的清晰度。
在一种实施方式中，获取第一图片的边缘清晰程度值时，可以获取第一图片的灰度图；对灰度图进行拉普拉斯变换，并得到拉普拉斯结果的方差；根据方差得到第一图片的边缘清晰程度值。
在一种实施方式中，判断第一图片的清晰度是否大于清晰度阈值还可以通过获取第一图片的第一分辨率以及清晰度阈值对应的分辨率阈值；若第一分辨率大于分辨率阈值，则确定第一图片的清晰度大于清晰度阈值。
需要说明的是，清晰度阈值可以根据具体的用户界面海报图片的设计需求设置，使得用户界面海报图片在用户界面上至少能够基本清晰的显示，本申请对清晰度阈值不作限制。
需要说明的是当第一图片的清晰度小于清晰度阈值时，则执行获取待显示于电子设备用户界面的预设位置的第一图片的步骤，直至获取到清晰度大于清晰度阈值的第一图片。
本申请实施例中，当第一图片的清晰度大于清晰度阈值时，获取第一图片的图片格式。其中，第一图片的图片格式可以是多种，比如JPG，PNG，GIF等图片格式，其中图片格式可以为无损压缩格式，也可以是有损压缩格式，可以理解的，比如JPG格式的第一图片是有损压缩格式，文件容量相对比较小，PNG格式的第一图片是无损压缩格式，文件容量相对比较大。
需要说明的是，在一种实施例中，若内存资源足够，也可以不获取第一图片的图片格式，直接对第一图片进行清晰度处理，清晰度处理可以包括锐化处理以及其他图片处理方式，以提高第一图片的清晰度。
在203中，若图片格式为无损压缩格式，则将第一图片进行压缩处理以得到压缩后的第一图片。
由于无损压缩格式的第一图片，其文件容量相对比较大，需要占用较大的内存资源，因此本申请实施例中，若第一图片的图片格式为无损压缩格式，则将第一图片进行压缩处理以得到压缩后的第一图片，比如，如果第一图片为PNG等无损压缩格式，可以将第一图片转换为WebP图片格式以减少第一图片所需占有的内存资源。若图片格式为有损压缩格式，则不需要对第一图片进行压缩处理，避免降低第一图片的清晰度。
需要说明的是，在一种实施例中，若内存资源足够，即使图片格式为无损压缩格式，也可以不对第一图片进行压缩处理，直接对第一图片进行清晰度处理，清晰度处理包括锐化处理以及其他图片处理方式，以提高第一图片的清晰度。
在204，对压缩后的第一图片进行锐化处理以得到锐化处理后的第一图片。
本申请实施例中，若第一图片的清晰度大于清晰度阈值，且第一图片的图片格式为有损压缩格式，则直接对第一图片进行锐化处理，以得到锐化处理后的第一图片。若第一图片的清晰度大于清晰度阈值，且第一图片的图片格式为无损压缩格式，则将第一图片进行压缩处理以得到压缩后的第一图片，再对压缩后的第一图片进行锐化处理，以得到锐化处理后的第一图片。
可以理解的，若第一图片具有较好的清晰度，则继续对第一图片进行锐化处理，锐化处理可以增强第一图片的边缘及灰度跳变的部分，有助于眼睛清楚看到第一图片中的细节，从而使锐化处理后的第一图片显得棱角分明、画面更加清晰，从而得到清晰度更好的第一图片。
需要说明的是，本申请实施例中除了可以对第一图片进行锐化处理之外，还可以进行其它清晰度处理，比如对图片的亮度、对比度、曲线、色阶、饱和度等参数进行调整，以使清晰度处理后的第一图片具有更好的清晰度。
在205，根据目标尺寸对锐化处理后的第一图片进行尺寸剪裁以得到第二图片。
可以理解的，在电子设备用户界面中，不同的用户界面的预设位置需要匹配不同的目标尺寸的用户界面海报图片，而锐化处理后的第一图片尺寸可能会与目标尺寸存在尺寸不匹配的问题。因此，本申请实施例中，可以根据目标尺寸对锐化处理后的第一图片进行尺寸剪裁以得到第二图片，以使第二图片匹配所需部署的用户界面的预设位置。当然，如果锐化处理后的第一图片的尺寸符合目标尺寸，则锐化处理后的第一图片即可直接作为第二图片，不需要根据目标尺寸进行尺寸剪裁。
可以理解的，当锐化处理后的第一图片的尺寸与目标尺寸不匹配时，如果对锐化处理后的第一图片的尺寸进行分辨率缩小处理，则会降低图片的清晰度，而本申请实施例是通过尺寸剪裁的方式以使得到的第二图片的尺寸既匹配所需部署的用户界面的预设位置，又不会降低清晰度。
在一种实施方式中，可以在设计第一图片时，就对所需的第一图片的尺寸大小根据目标尺寸进行规范化要求，以使获取的第一图片的尺寸尽量符合目标尺寸。
在一种实施方式中，锐化处理后的第一图片可能需要部署在电子设备用户界面中的多个预设位置，多个预设位置所需的目标尺寸存在一定的差异，则需要将锐化处理后的第一图片通过尺寸剪裁的方式获得多个尺寸不同的第二图片以匹配多个电子设备用户界面中的多个预设位置。
在206中，将第二图片设置在电子设备用户界面的预设位置。
可以理解的，由于第二图片具有更好的清晰度，且第二图片的尺寸大小匹配所需部署的电子设备用户界面中的预设位置，因此将第二图片作为用户界面海报图片设置在对应的电子设备用户界面中的预设位置，用户界面海报图片在对应的用户界面的预设位置将更加清晰的显示。
在一种实施方式中，为了确保第二图片的清晰度，可以在将第二图片设置在电子设备用户界面的预设位置之前，对第二图片进行再次清晰度的判断，具体的，可以获取第二图片的第二清晰度；若第二清晰度大于目标清晰度，则将第二图片设置在电子设备用户界面的预设位置。具体的，可以从图片元数据中获取所需部署的用户界面的预设位置信息。
在一种实施方式中，可以获取第二图片的边缘清晰程度值；判断边缘清晰程度值是否大于目标清晰度。具体的，获取第二图片的边缘清晰程度值可以获取第二图片的灰度图；对灰度图进行拉普拉斯变换，并得到拉普拉斯结果的方差；根据方差得到第二图片的边缘清晰程度值。
在一种实施方式中，判断第二图片的清晰度是否大于目标清晰度还可以通过获取第二图片的第二分辨率以及目标清晰度对应的目标分辨率；若第二分辨率大于目标分辨率，则确定第二图片的清晰度大于目标清晰度。
若第二图片的边缘清晰程度值大于目标清晰度，则说明第二图片可以在用户界面的预设界面呈现清晰的显示。
需要说明的是，目标清晰度也可以根据具体的用户界面海报图片的设计需求设置，使得用户界面海报图片在用户界面上可以呈现比较清晰的显示，目标清晰度值可以大于或等于清晰度阈值，本申请对目标清晰度值不作限制。
在一种实施方式中，当第二图片的清晰度不大于目标清晰度时，可以对第二图片继续进行清晰度处理，或者重新对第一图片进行清晰度处理，以使得到的第二图片的清晰度大于目标清晰度。
本申请实施例从用户界面海报图片的设计，用户界面海报图片的处理，用户界面海报图片的部署等多方面进行统筹规范化管理，保证了用户界面海报图片在用户界面预设位置可以清晰的显示。具体的，在进行用户界面海报图片的设计阶段，可以规范要求第一图片作为初始图片的清晰度，可以对第一图片根据清晰度进行选择，判断获取的第一图片的清晰度是否大于清晰度阈值，选择足够清晰的第一图片，从而后续可以跟据该第一图片得到清晰度较好的用户界面海报图片，防止选择清晰度不足的第一图片，导致后续跟据该第一图片无法得到足够清晰的用户界面海报图片；在用户界面海报图片的处理阶段，在获取到符合清晰度要求的第一图片后，若第一图片的图片格式为无损压缩格式，则将第一图片进行压缩处理以得到压缩后的第一图片，以减少第一图片所需的内存资源又不会明显降低第一图片的清晰度，若第一图片的图片格式为有损压缩格式，则不需要对第一图片进行压缩处理，以保持第一图片的清晰度；进一步的，继续对第一图片进行锐化处理，使锐化处理后的第一图片显得棱角分明、画面更加清晰，从而得到清晰度更好的第一图片；在用户界面海报图片部署的阶段，若锐化处理后的第一图片的尺寸大小与所需部署的用户界面的预设位置不匹配，则根据预设位置对应的目标尺寸对锐化处理后的第一图片进行尺寸剪裁以得到第二图片，以使得到的第二图片的尺寸既匹配所需部署的用户界面的预设位置，又不会降低清晰度，然后将清晰度较好的第二图片设置在电子设备用户界面的预设位置，从而大幅提高用户界面海报图片在用户界面上显示的清晰度。
请参阅图3，图3是本申请实施例提供的用户界面海报图片的处理方法的场景示意图。
在电子设备用户界面中，不同的位置需要对应不同的用户界面海报图片配合显示，因此根据不同位置的显示需要，需要获取不同的用户界面海报图片用于显示。
首先，获取待显示于电子设备用户界面的预设位置的第一图片，第一图片可以作为初始图片，用于后续处理得到所需要的用户界面海报图片。在一种实施方式中，可以根据具体的用户界面的显示需要，设计得到第一图片。在对第一图片进行设计时，可以对设计质量进行规范化要求，比如要求设计的第一图片的图片分辨率、图片清晰度等需符合规范化要求，避免由于设计不规范导致获取不符合清晰度需求的初始图片。
其次，获取到第一图片后，会对第一图片根据清晰度进行确认，判断获取的第一图片的清晰度是否大于清晰度阈值。可以理解的，如果第一图片的边缘清晰度值大于清晰度阈值，则可以说明该第一图片整体都具有足够的清晰度。当第一图片的清晰度小于清晰度阈值时，则继续执行获取待显示于电子设备用户界面的预设位置的第一图片的步骤，直至获取到清晰度大于清晰度阈值的第一图片。
再次，在获取到符合清晰度要求的第一图片后，若第一图片的图片格式为无损压缩格式，则将第一图片进行压缩处理以得到压缩后的第一图片，以减少第一图片所需的内存资源又不会明显降低第一图片的清晰度。
再次，继续对第一图片进行锐化处理，从而使锐化处理后的第一图片显得棱角分明、画面更加清晰，从而得到清晰度更好的第一图片。
最后，在用户界面海报图片部署的阶段，若锐化处理后的第一图片的尺寸大小与电子设备用户界面中的预设位置不匹配，则根据预设位置对应的目标尺寸对锐化处理后的第一图片进行尺寸剪裁以得到第二图片，从而保持了锐化处理后的第一图片的清晰度，再将符合目标尺寸，且清晰度较好的第二图片设置在电子设备用户界面的预设位置；若锐化处理后的第一图片的尺寸大小与电子设备用户界面中的预设位置相匹配，则直接将锐化处理后的第一图片作为第二图片设置在电子设备用户界面的预设位置，从而大幅提高用户界面海报图片在用户界面上显示的清晰度。
