Description

相机模组故障检测方法及装置
本专利申请要求申请日为2015年11月08日、申请号为2015107583354的中国专利申请的优先权，并将上述专利申请以引用的方式全文引入本文中。

背景技术
目前智能手机逐渐融入到了人们日常生活之中，不但成为日常通讯设备，也成为日常易于携带的娱乐设备。例如，用户可以使用智能手机的备忘录等功能记录会议等事物，还可以使用智能手机中的相机来进行拍照。而且随着智能手机中相机的配置越来越高，并且基于智能手机的便携性，用户越来越喜欢用智能手机上的相机进行拍照。
随着用户使用智能手机的时限变长，相机模组出现故障的频率也随之开始逐渐变大。目前当相机模组出现故障后，用户再调用相机时，就无法将其打开。然而实际上智能手机上的相机模组并未出现致命的故障，只是智能手机在系统检测和设置过程中出现偏差，从而中断加载相机服务造成无法打开相机。目前，智能手机可以读取相机校准值的一次性可编程(One Time Programmable，简称OTP)数据，当读取到OTP数据中某固定位置读数非为预定值时，不再加载相机模组，上述相机模组故障判定的方法考虑的因素较为单一，限制了相机模组的使用，导致用户体验较差。

具体实施方式
下面结合附图对本申请实施例提供的相机模组故障识别方法及装置进行详细描述。
实施例一
如图1所示，其为本申请实施例一的相机模组故障识别方法的流程示意图，该相机模组故障识别方法包括：
步骤101、获取相机模组的一次性可编程OTP数据。
具体地，在用户试图调用智能手机上的相机时，会通过点击触摸屏上的相机图标向智能手机发送指令，当智能手机探测到该点击操作后，就可以对相机模组进行测试。本实施例中，智能手机可以获取相机模组的OTP数据，以根据该OTP数据判断相机模组是否出现故障。
步骤102、根据所述OTP数据判断所述相机模组是否故障。
一般当获取到OTP数据后，智能手机对OTP数据进行分析，以判断相机模组是否出现故障，当读取到OTP数据中某固定位置读数非为预定值时，则判定相机模组出现故障，不再加载相机模组。然而实际上智能手机上的相机模组并未出现致命的故障，只是智能手机在系统检测和设置过程中出现偏差，从而中断加载相机服务造成无法打开相机。为了提高相机模组的使用效率，本实施例在步骤102判定结果为是时，需要进步执行步骤103，如果判断结果为否，执行步骤105启动相机模组。
步骤103、从所述OTP数据中提取第一自动白平衡AWB值、第一镜头阴影校正LSC值和第一自动对焦AF值。
其中，所述第一AF值包括第一远焦端对应值(Infinity)和第一近焦端对应值(Micro)。
智能手机对获取的OTP数据进行解析，从中可以提取出第一自动白平衡(Automatic White Balance，简称AWB)值、第一镜头阴影校 正(Lens Shading Correction，简称LSC)值以及第一自动对焦(Automatic Focus，简称AF)值。其中，第一AF值包括第一Infinity值和第一Macro值。
步骤104、分别判断所述第一AWB值、所述第一LSC值和所述第一AF值是否合法。
本实施例中，为相机模组的第一AWB值、第一LSC值以及第一AF值分别设置有判断策略。在提取出第一AWB值、第一LSC值和第一AF值之后，智能手机需要分别判断第一AWB值、第一LSC值和第一AF值是否合法。例如，将第一AWB值、第一LSC值以及第一AF值分别设置有一个合法范围，当相应的值未超出相应的合法范围时，则可以判断该相应的值为合法的数值，该相应的值就可用。
如果判断出第一AWB值、第一LSC值和第一AF值均合法，则执行步骤105；如果判断出第一AWB值、第一LSC值和第一AF值至少一个非法，则执行步骤106。
步骤105、启动相机模组。
在判断出上述第一AWB值、第一LSC值以及第一AF值均为合法数值后，就可以指示启动相机模组。具体地，指示读取相机模组中的传感器(Sensor)对应的标识(Identification，简称ID)。在读取Sensor ID成功后，启动相机模组，进入相机模组的操作界面下。
步骤106、禁用相机模组。
当第一AWB值、第一LSC值和第一AF值中的至少一个为非法数值时，说明相机模组出现了较为严重的故障，此时相机模组将会被禁用。
本实施例提供的相机模组故障检测方法，通过获取相机模组的OTP数据，根据OTP数据判断相机模组是否故障，如果判断结果为是，从OTP数据中提取第一AWB值、第一LSC值和第一AF值；其中，第一AF值包括第一远焦端对应值和第一近焦端对应值，分别判断第一AWB值、第一LSC值和第一AF值是否合法，如果判断结果为第一AWB值、第一LSC值和第一AF值均合法，启动相机模组，在用 OTP数据判断相机模组故障后，利用AWB值、LSC值和AF值进步判断该故障的严重程度，在故障不严重时可启用相机模组，提高了相机模组的使用效率，并且提升了用户感受。
实施例二
如图2所示，其为本申请实施例二的相机模组故障探测方法的流程示意图，该相机模组故障探测方法包括：
步骤201、获取相机模组的OTP数据。
步骤202、根据所述OTP数据判断所述相机模组是否故障。
如果判断结果为是，执行步骤203，如果判断结果为否，则执行步骤207。
步骤203、从所述OTP数据中提取第一自动白平衡AWB值、第一镜头阴影校正LSC值和第一自动对焦AF值。
其中，所述第一AF值包括第一远焦端对应值和第一近焦端对应值。
步骤201～步骤203的过程可参见上述实施例一中步骤101～步骤103中相关内容的记载，此处不再赘述。
步骤204、判断所述第一AWB值是否合法。
具体地，智能手机将第一AWB值与预存在系统中的第二AWB值进行比较，如果第一AWB值与第二AWB值的绝对差值在预定的范围内，则判定第一AWB值合法。
实际上，图像信号处理(Image Signal Processing，简称ISP)中设有调整(Tuning)参数，在该Tuning参数中符合正太分布的黄金(Golden)模组所对应的第二AWB值(B/G,R/G)，该第二AWB值均存在于系统当中。本实施例中的相机模组为厂商出厂的特定(Spec)中规定量产的相机模组，该相机模组的第一AWB值和Golden模组的第二AWB值之间的差异要保证在10％以内，就可以判断出第一AWB值在合理的范围内。如在合理范围内，就可认为该第一AWB值可以使用。
如果判断第一AWB值合法，则执行步骤205；否则，执行步骤 210。
步骤205、判断所述第一LSC值是否合法。
进一步地，智能手机将第一LSC值与预存在系统中的第二LSC值进行比较，如果第一LSC值与第二LSC值的绝对差值在预定的范围内，则判定第一LSC值合法。
实际上，ISP中设有的Tuning参数中有Golden模组所对应的第二LSC值，该第二LSC值均存在于系统当中。本实施例中的相机模组为厂商出厂的Spec中规定量产相机模组，该相机模组的第一LSC值和Golden模组的第二LSC值之间的差异要保证在10％以内，就可以判断出第一LSC值在合理的范围内。如在合理范围内，就可认为该第一LSC值可以使用。
如果判断第一LSC值合法，则执行步骤206；否则，执行步骤210。
步骤206、判断所述第一AF值是否合法。
进一步地，智能手机将第一Infinity值和第一Macro值分别与预存在系统中的第二AF值中所包含的第二Infinity值和第二Macro值进行比较；其中，第二AF值预存在系统中。如果第一Infinity值和第二Infinity值的绝对差值以及第一Macro值与第二Macro值的绝对差值均在预定的范围内，则判定第一AF值合法。
实际上，ISP中设有的Tuning参数中有Golden模组所对应的第二AF值，其中，第二AF值中包含第二Infinity值和第二Macro值，该第二LSC值均存在于系统当中。本实施例中的相机模组为厂商出厂的Spec中规定量产相机模组，该相机模组的第一AF值中的第一Infinity值和第一Macro值与Golden模组的第二Infinity值和第二Macro值之间的差异要保证在20％以内，就可以判断出第一AF值在合理的范围内。如在合理范围内，就可认为该第一AF值可以使用。
如果判断第一AF值合法，则执行步骤207，否则，执行步骤210。
步骤207、发送读取所述相机模组中的传感器标识的指令。
步骤208、根据所述指令读取所述传感器标识。
步骤209、若成功读取所述传感器标识，则启动所述相机模组。
步骤210、禁用相机模组。
