本发明涉及图像处理技术领域，尤其涉及一种图像展现方法、装置、设备及计算机程序产品。
二维码是按一定规律在平面(二维方向)上分布的黑白相间的图形，二维码中存储有数字、文字或图片等信息。通过扫描二维码，可以自动识读并处理二维码中存储的信息。在实际生活中，二维码技术可应用在产品防伪/溯源、广告推送、网站链接、数据下载、商品交易、定位/导航、电子凭证、车辆管理、信息传递、名片交流、无线保真(Wireless Fidelity，WIFI)共享等技术领域。
在日常生活中，二维码扫描技术多见于地铁、公交、微信、微博等可近距离扫描的场景，即用户需要手持终端近距离扫描二维码图像。随着智能电视技术的迅速发展，用户在使用智能电视的过程中也难免要用到二维码扫描技术，例如，用户可以通过扫描智能电视上展现的二维码图像，来实现账户登陆、数据下载、商品交易等目的，从而简化了用户的操作。但是，由于用户与智能电视之间的距离一般为二到三米，因此用户在扫描智能电视展现的二维码图像时，需要进行远距离扫描，而众所周知，二维码图像的尺寸比较小，且常常夹杂在各种文字或图像中间，如图1所示，用户很可能无法成功扫描到二维码图像，那么就需要用户走近智能电视再次进行扫描，给用户的正常使用造成不便，使得扫描二维码图像的灵活性较差，此外，也降低了扫描图像的成功率，延长了扫描二维码图像的响应时间。
此外，用户在扫描智能电视上展现的其他图像(例如一维条码图像)时也会存在上述问题。

现有技术中，用户在扫描智能电视上展现的图像(二维码图像或一维条码图像)时，需要进行远距离扫描，由于图像的尺寸比较小，且常常夹杂在各种文字或图像中间，因此用户很可能无法成功扫描到图像，那么就需要用户走近智能电视进行扫描，从而给用户的正常使用造成不便，使得扫描图像的灵活性较差，此外，也延长了扫描图像的响应时间。
有鉴于此，本发明实施例提出了一种图像展现方法，当接收到用户针对待扫描图像的图像放大请求后，可以对该待扫描图像进行放大处理，然后再展现给用户，用户就可以扫描放大处理后的图像，避免了由于待扫描图像的尺寸较小造成的扫描失败的情况，提高了扫描成功率，无需用户走近智能电视再次进行扫描，提高了扫描图像的灵活性，也缩短了扫描图像的响应时间。
下面通过具体实施例对本发明方案进行详细描述，当然，本发明并不限于以下实施例。
实施例一
如图2所示，为本发明实施例一提出的图像展现方法流程图，其具体处理过程如下：
步骤21，将待扫描图像展现给用户后，接收用户针对所述待扫描图像的图像放大请求。
其中，上述待扫描图像可以但不限于为一维条码图像或二维码图像。
智能电视将待扫描图像通过显示屏幕展现给用户后，用户如果认为展现的待扫描图像的尺寸比较小，可能无法成功扫描，则可以通过数字遥控器触发放大待扫描图像的操作，本发明实施例一提出，可以但不限于采用下述两种方式来触发放大待扫描图像的操作，具体为：
第一种触发方式，用户通过数字遥控器移动定位焦点，使定位焦点位于待扫描图像上，智能电视若监测到定位焦点位于该待扫描图像上的时长大于预设时长，则可以认为用户想要触发放大该待扫描图像的操作，因此确认接收到用户针对该待扫描图像的图像放大请求。
例如，上述预设时长为2秒，智能电视若监测到用户将定位焦点移动至该待扫描图像上，且定位焦点位于该待扫描图像上的时长大于2秒时，可以认为用户想要触发放大该待扫描图像的操作。
第二种触发方式，用户通过数字遥控器移动定位焦点，使定位焦点位于待扫描图像上，然后用户点击数字遥控器上的“确定”按键，相当于用户针对该待扫描图像执行了点击操作，此时可以认为用户想要触发放大该待扫描图像的操作，因此确认接收到用户针对该待扫描图像的图像放大请求。
步骤22，按照预设的放大规则，对所述待扫描图像进行放大处理。
本发明实施例一提出，为了使用户能够轻松扫描到待扫描图像，可以在接收到用户针对该待扫描图像的图像放大请求后，直接将该待扫描图像放大到最大尺寸，其中，预先在显示屏幕的显示区域中选取用于呈现待扫描图像的设定显示区域，若待扫描图像的至少两
条边位于设定显示区域的边界上，而其他边位于设定显示区域内，则此时待扫描图像的尺寸即为最大尺寸，若对该待扫描图像继续进行放大处理，则会使得该待扫描图像的至少两条边位于设定显示区域外。
将该待扫描图像进行放大处理时，先确定待扫描图像的尺寸以及设定显示区域的尺寸，然后根据待扫描图像的尺寸以及设定显示区域的尺寸，确定放大后的待扫描图像的尺寸，再按照确定出的放大后的待扫描图像的尺寸，对该待扫描图像进行放大处理。
较优的，上述用于呈现待扫描图像的设定显示区域可以为显示屏幕的整个显示区域，也就是说，在接收到用户针对该待扫描图像的图像放大请求后，直接将该待扫描图像放大到整个屏幕。
例如，设定显示区域的宽为a，高为b，且a大于b，如图3所示，待扫描图像在放大处理前的尺寸为c*c，即宽和高均为c，如图4所示，放大后的待扫描图像的高和宽均为b，与设定显示区域的高相等，因此待扫描图像在放大处理后的尺寸为b*b。
本发明实施例一提出，可以采用矩阵变换的方式，对待扫描图像进行放大处理，将待扫描图像看作一个由各个像素点的像素值组成的像素矩阵，根据放大前的待扫描图像的尺寸以及放大后的待扫描图像的尺寸，确定放大待扫描图像时的变换矩阵，然后将放大前的待扫描图像的像素矩阵与该变换矩阵相乘，就可以得到放大后的待扫描图像的像素矩阵。
此外，本发明实施例一提出，也可以通过本实施例方案，将待扫描图像逐步放大，每次接收到用户针对待扫描图像的放大请求后，均将待扫描图像放大设定倍数，直至放大到最大尺寸，使用户能够随意调整待扫描图像的尺寸，提高了扫描图像的灵活性。
由于在每次进行放大处理时，放大后的待扫描图像有可能超出了设定显示区域的边界，因此在每次放大处理前，需要先判断按照设定倍数放大后的待扫描图像是否超出了设定显示区域的边界，若判断结果为否，则按照设定倍数，对待扫描图像进行放大处理，若判断结果为是，则将该待扫描图像放大至最大尺寸，具体的，确定待扫描图像的尺寸以及设定显示区域的尺寸，然后根据待扫描图像的尺寸以及设定显示区域的尺寸，确定放大后的待扫描图像的尺寸，再按照确定出的放大后的待扫描图像的尺寸，对该待扫描图像进行放大处理。
例如，上述设定倍数为2倍，智能电视将待扫描图像展现给用户后，用户认为可能无法成功扫描该待扫描图像，因此用户可以采用上述第一种触发方式或第二种触发方式触发放大待扫描图像的操作，智能电视判断将该待扫描图像放大2倍后是否超出了设定显示区域的边界，若未超出，则将放大2倍后的待扫描图像展现给用户，若用户仍然觉得无法成功扫描该待扫描图像，则可以继续触发放大待扫描图像的操作，智能电视判断将该待扫描图像再放大2倍后是否超出了设定显示区域的边界，若已超出，则将该待扫描图像放大至最大尺寸后展现给用户。
步骤23，将放大后的待扫描图像展现给用户。
本发明实施例一提出，在将放大后的待扫描图像展现给用户时，可以只在显示屏幕的显示区域内展现放大后的待扫描图像，而不展现其他信息。
也可以在显示区域内将放大后的待扫描图像置于其他信息之上。较优的，为了在显示区域中突出放大后的待扫描图像，提高扫描图像的成功率，也可以将其他信息进行透明淡化处理。
本发明实施例一提出，为了便于用户扫描，提高扫描图像的成功率，可以将放大后的待扫描图像置于显示区域的中间位置。
本发明实施例一提出的图像展现方法可以但不限于应用在智能电视中。
由上可见，当接收到用户针对待扫描图像的图像放大请求后，可以对该待扫描图像进行放大处理，然后再展现给用户，用户就可以扫描放大处理后的图像，避免了由于待扫描图像的尺寸较小造成的扫描失败的情况，提高了扫描成功率，无需用户走近智能电视再次进行扫描，提高了扫描图像的灵活性，也缩短了扫描图像的响应时间。
此外，若用户想要将放大后的待扫描图像恢复为原尺寸，则可以通过数字遥控器触发恢复待扫描图像的操作，智能电视在接收到用户针对该待扫描图像的图像恢复请求后，对待扫描图像进行缩小处理，然后将缩小后的待扫描图像展现给用户。本发明实施例一提出，用户可以但不限于采用下述两种方式来触发恢复待扫描图像的操作，具体为：
与上述第一种触发方式对应，用户通过数字遥控器移动定位焦点，使定位焦点位于放大后的待扫描图像上，智能电视若监测到定位焦点位于该放大后的待扫描图像上的时长大于预设时长，则可以认为用户想要触发后恢复该待扫描图像的操作，因此确认接收到用户针对该待扫描图像的图像恢复请求。
与上述第二种触发方式对应，用户通过数字遥控器移动定位焦点，使定位焦点位于放大后的待扫描图像上，然后用户点击数字遥控器上的“确定”按键，相当于用户针对该放大后的待扫描图像执行了点击操作，此时可以认为用户想要触发恢复该待扫描图像的操作，因此确认接收到用户针对该待扫描图像的图像恢复请求。
若在对待扫描图像进行放大处理时，直接将该待扫描图像放大到最大尺寸，则在对放大后的待扫描图像进行缩小处理时，可以直接将放大后的待扫描图像缩小至原始尺寸。
若在对待扫描图像进行放大处理时，将待扫描图像逐步放大，每次接收到用户针对待扫描图像的放大请求后，均将待扫描图像放大设定倍数，直至放大到最大尺寸，则在对放大后的待扫描图像进行缩小处理时，可以将待扫描图像逐步缩小，每次接收到用户针对待扫描图像的恢复请求后，均将待扫描图像缩小设定倍数，直至缩小到原始尺寸。在每次缩小处理前，需要先判断按照设定倍数缩小后的待扫描图像是否小于该待扫描图像的原始尺寸，若判断结果为否，则按照设定倍数，对待扫描图像进行缩小处理，若判断结果为是，
则将该待扫描图像缩小至原始尺寸。
