Description

一种智能终端相机控制方法 技术领域
本发明涉及智能终端控制领域，尤其涉及一种智能终端相机控制方法。
技术背景
目前安卓手机随着CPU性能的提升,相机像素的增加,使得用户可以使用普通相机拍出比较专业的图片。
目前，在相机使用时，经常发现在专业模式下，滑动到无穷远预览10米之外的景物时,并不能做到预览最清晰，原因是镜头马达从最小值变化为最大值时，两者的code值相差较大，一致性差。由于原先的最小值和最大值为预先设置，这样在不同的智能终端中，成像效果大相径庭。
因此，需要一种新型智能终端相机控制方法，能自动准确获得每颗镜头马达对应最小值及最大值。
发明概要
为了克服上述技术缺陷，本发明的目的在于提供一种智能终端相机控制方法，即便智能终端的相机一致性不同，也可准确地获取近景和远景的code值。
本发明公开了一种智能终端相机控制方法，包括以下步骤：
步骤1：启动智能终端，读取相机传感器内OTP，以烧录所述相机的micro和infinity值，并写入一文件节点内；
步骤2：启动相机；
步骤3：自所述文件节点内读取所述micro和infinity值；
步骤4：分拆所述micro和infinity值至一需求份数，并将所述需求份数赋值至智能终端***内的相机位置key值。
优选地，所述文件节点位于所述智能终端***的sys/class/focus/focus/focus_level路径上。
优选地，所述步骤4中，根据等差数列拆分所述micro和infinity值。
优选地，所述相机位置key值为pref_camera_afeng_pos_key。
优选地，所述步骤2和步骤3间，还包括：步骤2’:初始化智能终端***内的列表偏好选项。
优选地，所述控制方法的步骤2’和步骤3间还包括：
步骤5：判断智能终端是否首次启动，若是，则执行步骤3，若否，则执行步骤4。
优选地，所述micro和infinity值存储与static变量min_value和max_value中。
采用了上述技术方案后，与现有技术相比，具有以下有益效果：
1.任意品牌的智能终端内的任意相机可自动获取马达的micro和infinity值，提高了一致性；
2.照片成像效果内的景深和锁附深度更佳。
附图说明
图1为符合本发明一优选实施例中相机管理方法的流程示意图。
发明内容
以下结合附图与具体实施例进一步阐述本发明的优点。
参阅图1，本发明提供了一种智能终端相机控制方法，并通过以下步骤执行实现：
步骤1：对智能终端开机启动，使得智能终端的***读取相机传感器内的OTP，并将读取后的相机的micro和infinity值烧录至其内，则在智能终端启动后的OTP内，已记录有相机预设的micro和infinity值，相机在后续启用时，可调用烧录的micro和infinity值。在烧录完成后，将把该micro和infinity值写入文件节点内，以供后续调用。
步骤2：文件节点形成后，启动相机；
步骤3：相机自文件节点读取micro和infinity值，以调用，以矫正不同相机模组在组装时对近景和远景的差异值。
步骤4：获取了micro和infinity值后，对micro和infinity值形成的最小值和最大值进行拆分，分解成多份数据值，这些多份数据值将以一需求份数的形式最终赋值至智能终端***内的相机位置key值处，例如pref_camera_afeng_pos_key。针对micro和infinity值形成的最小值和最大值，并根据准度决定需求份数，以等差数列的形式拆分，可形成具有阶梯度近景和远景code值，使得相机可在这些值中选择，固定化一致化不同相机的拍摄参数。
可以理解的是，上述步骤4中，若决定拆分的等差数列的公差越小，需求份数将越大，相机取景的准度效果也将越好。
在一优选实施例中，文件节点位于智能终端***的sys/class/focus/focus/focus_level路径上，直接地写入***内部，减少调用参 数时对***内存的占用，并加快了调用的速度。
优选或可选地，步骤2和步骤3间，还包括了：
步骤2’：在智能终端***内初始化列表偏好选项，以重新确定列表偏好选项listpreference的可选内容，替换原有的近景和远景对焦参数。
进而，步骤2’和步骤3间还包括：
步骤5：判断智能终端是否首次启动，若是，则执行步骤3，将micro和infinity值存储与static变量min_value和max_value中，以将micro和infinity值烧录至***内，若否，则直接执行步骤4，对***内已有的static变量min_value和max_value进行按需求份数拆分micro和infinity值的步骤。
应当注意的是，本发明的实施例有较佳的实施性，且并非对本发明作任何形式的限制，任何熟悉该领域的技术人员可能利用上述揭示的技术内容变更或修饰为等同的有效实施例，但凡未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何修改或等同变化及修饰，均仍属于本发明技术方案的范围内。
