管发射红外线， 如果有物体将发射的红外线反射回来， 则反射的红外线经过手机屏幕等物 理结构隔挡后被红外线接收器接收。 其中， 当手机中的红外线发射二级管工作时， 手机通 过红外线接收器实时接收红外线， 并从接收的红外线中获取反射的红外线的强度值， 如果 反射的红外线的强度值超过预设门限值， 则确定出有物体接近手机。
在实现本发明的过程中， 发明人发现现有技术至少存在以下问题：
红外线接收器接收的红外线要经过手机的屏幕等物理结构隔挡， 因此获取反射的红外 线的强度值存在因手机物体结构而产生的影响， 但每个手机产生的影响都各不相同， 如果 在每个手机中设置相同的门限值， 使得有些手机无法精确地确定出是否有物体接近。 发明内容

为使本发明的目的、 技术方案和优点更加清楚， 下面将结合附图对本发明实施方式作 进一步地详细描述。 实施例 1
如图 1所示， 本发明实施例提供了一种终端确定物体接近的方法， 包括：
步骤 101 : 红外线接收器读取红外发射二极管不工作时的第一红外线强度值， 并且红外 线接受器读取红外发射二极管工作时的第二红外线强度值；
步骤 102: 获取第二红外线强度值与第一红外线强度值之间的第一差值， 作为反射的红 外线强度值；
步骤 103 :判断反射的红外线强度值与终端自身存储的红外线强度阈值之间的第二差值 是否大于预设的第二阈值；
步骤 104: 当第二差值大于所述预设的第二阈值时， 则确定有物体接近终端。
在本发明实施例中， 获取反射的红外线强度值， 判断获取反射的红外线强度值与终端 自身存储的红外线强度阈值之间的第二差值是否大于预设的第二阈值， 当第二差值大于预 设的第二阈值， 则确定有物体接近终端。 在判断获取反射的红外线强度值与终端自身存储 的红外线强度阈值之间的第二差值是否大于预设的第二阈值时可以消除终端的物理结构产 生的影响， 如此可以在每个终端设置相同的第二阈值， 从而使得每个终端都能精确地确定 是否有物体接近。 实施例 2
本发明实施例提供了一种终端确定物体接近的方法。 终端内有红外线发射二极管和红 外线接收器组成的接近光传感器， 且终端利用本实施提供的确定物体接近的方法， 来确定 是否有物体接近终端。 参见图 2， 该方法包括：
步骤 201 : 通过红外线接收器读取红外线发射二极管不工作时的第一红外线强度值 Ir， 并缓存第一红外线强度值 Ir;
具体地， 停止红外线发射二极管继续工作， 通过红外线接收器接收外界的红外线， 并 读取接收的红外线的第一红外线强度值 Ir，其中，红外线发射二极管不工作时接收的红外线 为环境中的红外线， 因此第一红外线强度值 Ir为环境中的红外线强度值。
步骤 202: 开启终端内的红外线发射二极管， 通过红外线接收器接收红外线并读取接收 的红外线的强度值 Psl ;
其中， 开启终端内的红外线发射二极管后， 红外线发射二极管实时地向外发射红外线， 终端内的红外线接收器实时接收红外线， 且接收的红外线包括环境中的红外线， 还可以包 括红外线发射二极管向外发射的红外线被反射回来的红外线； 因此， 读取红外线接收器接 收的红外线的强度值 Psl 包括第一红外线强度值 Ir， 还可以包括反射的红外线的强度值 Psl l o
其中， 终端内的红外线发射二极管向外发射红外线， 会因空气等因素将部分的红外线 反射回去， 并被终端内的红外线接收器接收； 如果位于终端发射红外线的方向上有物体， 则物体会将红外线发射二极管发射的红外线反射回去， 并被终端内的红外线接收器接收； 如果位于终端发射红外线的方向上的物体离终端越接近， 红外线接收器接收到物体反射的 红外线的强度就越大。
步骤 203 : 根据读取的红外线的强度值 Psl和第一红外线强度值 Ir， 获取反射的红外线 强度值 Psl l， 将反射的红外线强度值 Psl l作为红外线强度阈值并缓存该红外线强度阈值； 具体地，计算读取的红外线的强度值 Psl与第一红外线强度值 Ir之间的第一差值 Psl l， 第一差值 Psl l等于 Psl-Ir， 其中， 计算的第一差值 Psl l即为反射的红外线强度值， 将计算 的第一差值 Psl l作为红外线强度阈值， 并缓存该红外线线强度阈值。
其中， 反射的红外线需要经过终端的屏幕等物理结构隔挡后， 被终端内的红外线接收 器接收， 因此获取的第一差值， 即红外线强度阈值存在因终端的物理结构隔挡而产生的影 响。
其中， 终端内的红外线发射二极管实时地向外发射红外线， 且终端内的红外线接收器 实时接收红外线， 当再次接收到红外线时， 继续执行步骤 204。
步骤 204: 通过红外线接收器接收外界的红外线并读取接收的红外线的强度值 Ps2， 根 据接收的红外线的强度值 Ps2和第一红外线强度值 Ir获取反射的红外线强度值 Ps21 ;
具体地， 通过终端内的红外线接收器接收红外线， 并读取接收的红外线的强度值 Ps2， 计算读取的红外线的强度值 Ps2与第一红外线强度值 Ir之间的第一差值 Ps21，第一差值 Ps21 等于 Ps2-Ir， 其中， 计算出的第一差值 Ps21为反射的红外线强度值 1。
其中， 获取反射的红外线强度值 Ps21也存在因终端的物理结构而产生的影响， 但是对 于同一个终端， 每次产生的影响都是相同的。
步骤 205: 比较获取反射的红外线强度值 Ps21与缓存的红外线强度阈值 Psl l， 如果小 于， 则执行步骤 206， 如果大于， 则执行步骤 207;
步骤 206: 将缓存的红外线强度阈值 Psll更新为获取反射的红外线强度值 Ps21， 结束 操作；
步骤 207: 根据获取反射的红外线强度值 Ps21和缓存的红外线强度阈值 Psl l， 计算出 第二差值；
其中， 缓存的红外线强度阈值 Psll存在因终端的物理结构隔挡而产生的影响， 获取反 射的红外线强度值 Ps21也存在因终端的物理结构隔挡而产生的影响； 又因为对于同一终端 每次产生的影响都相同， 因此， 计算出第二差值 Ps21-Psll消除终端的物理结构隔挡而产生 的影响。
步骤 208: 根据计算的第二差值和预设的第二阈值确定是否有物体接近终端。
具体地， 比较计算的第二差值与预设的第二阈值， 如果超过预设的第二阈值， 则确定 出有物体接近终端， 如果未超过预设的第二阈值， 则确定出没有物体接近终端。
其中， 当位于终端发射红外线的方向上的物体离终端越来越近时， 终端内的红外线接 收器接收到物体反射红外线发射二极管发射的红外线的强度越来越强， 使得计算出的第二 差值越来越大， 当计算出的第二差值超过预设的第二阈值， 则可以确定出有物体接近终端。
其中， 计算出的第二差值消除了终端的物理结构隔挡而产生的影响， 因此可以在每个 终端中预先设置相同的第二阈值， 来确定是否有物体接近终端。
其中， 当终端的红外线接收再次接收到外界的红外线时， 返回执行步骤 204。
其中， 在本实施例中， 步骤 205和 206是可选的步骤， 即接近光传感器初次启动并在 步骤 203 中首次缓存红外强度阈值之后， 每次获取到反射的红外线强度值时可以直接获取 反射的红外线强度值与首次缓存的红外线强度值之间的第二差值并根据第二差值和预设的 第二阈值确定是否有物体接近终端， 所以可以不需要执行步骤 205和 206。
在本发明实施例中， 首先获取并缓存红外线强度阈值， 然后每当接收到外界的红外线 时， 获取反射的红外线强度值， 如果反射的红外线强度值小于缓存的红外线强度阈值， 则 计算反射的红外线强度值与缓存的红外线强度阈值之间的第二差值； 其中， 对于同一终端， 终端对每次接收的反射的红外线强度值的影响都相同， 因此在计算反射的红外线强度值与 缓存的红外线强度阈值之间的第二差值时， 消除终端的物理结构的影响， 从而可以在每个 终端中设置相同的第二阈值， 并使每个终端精确地确定是否有物体接近。 实施例 3
如图 3所示， 本发明实施例提供了一种终端确定物体接近的方法， 包括：
步骤 301 : 当终端的红外线发射二极管开启时， 接收外界的红外线， 读取并缓存接收的 红外线的强度值；
步骤 302: 当再次接收到外界的红外线时， 读取再次接收的红外线的强度值， 计算出再 次接收的红外线的强度值与缓存的红外线强度值之间的差值；
步骤 303 : 当计算的差值大于预设的第二阈值时， 则确定有物体接近终端。
在本发明实施例中， 首先获取并缓存接收的红外线的强度值， 然后每当接收到外界的 红外线时， 读取接收的红外线的强度值， 根据读取的红外线强度值和缓存的红外线强度值 计算出差值， 根据计算出的差值和预设的第二阈值确定是否有物体接近终端。 其中， 对于 同一终端， 终端对每次接收的反射的红外线的强度值的影响都相同， 因此在计算读取的红 外线强度值与缓存的红外线强度值的差值时， 消除终端的物理结构的影响， 从而可以在每 个终端中设置相同的第二阈值， 并使每个终端都能精确地确定是否有物体接近。 实施例 4
本发明实施例提供了一种终端确定物体接近的方法。 终端内有红外线发射二极管和红 外线接收器， 且终端利用本实施提供的确定物体接近的方法， 来确定是否有物体接近终端。 参见图 4， 该方法包括：
步骤 401 :当终端内的红外线发射二极管开启时，通过红外线接收器接收外界的红外线； 其中， 当红外线发射二极管开启时， 红外线发射二极管向外发射红外线， 且存在部分 发射的红外线会被空气等物质反射回来； 另外， 环境中也会存在红外线； 因此， 红外线接 收器接收的红外线包括环境中的红外线和反射的红外线。
步骤 402: 读取接收的红外线的强度值， 并缓存读取的红外线强度值；
其中， 接收的红外线包括环境中的红外线和反射的红外线， 因此读取的红外线的强度 值包括反射的红外线的强度值和环境中的红外线的强度值。
其中， 反射的红外线需要经过终端的屏幕等物理结构隔挡后， 被终端内的红外线接收 器接收， 因此读取的反射的红外线的强度值存在因终端的物理结构隔挡而产生的影响。
其中， 终端内的红外线发射二极管实时地向外发射红外线， 终端内的红外线接收器实 时地接收红外线， 当再次接收到红外线时， 执行步骤 403。
步骤 403 : 通过红外线接收器接收外界的红外线， 并读取接收的红外线的强度值； 其中， 接收的红外线包括环境中的红外线和反射的红外线， 因此此次读取的红外线的 强度值包括反射的红外线的强度值和环境中的红外线的强度值。 另外， 环境中的红外线的 强度较稳定， 因此每次读取的红外线的强度值中包括环境中的红外线的强度值都相同。
其中， 反射的红外线需要经过终端的屏幕等物理结构隔挡后， 被终端内的红外线接收 器接收， 因此读取的反射的红外线的强度值也存在因终端的物理结构隔挡而产生的影响。
步骤 404: 计算读取的红外线强度值和缓存的红外线强度值之间的差值；
其中， 每次读取的红外线的强度值中包括环境中的红外线的强度值都相同， 因此将读 取的红外线强度值与缓存的红外线强度值作差运算， 得到的差值为反射的红外线的强度差 值。
其中， 对于同一终端， 终端的物理结构对每次接收反射的红外线的影响都相同以及每 次读取的环境中的红外线的强度值也相同， 因此将读取的红外线的强度值与缓存的红外线 的强度值作差运算， 可以消息终端的影响以及环境中的红外线的强度值。
步骤 405 : 根据计算的差值和预设的第二阈值确定是否有物体接近终端。
具体地， 判断计算的差值是否超过预设的第二阈值， 如果是， 则确定出有物体接近终 端， 如果否， 则确定出没有物体接近终端。
其中， 在计算读取的红外线强度值和缓存的红外线强度值之间的差值时消除终端的物 理结构产生的影响， 因此可以在每个终端中预先设置相同的第二阈值来确定是否有物体接 近终端。
其中， 当终端内的红外线接收器再次接收的外界的红外线时， 返回执行步骤 403。 在本发明实施例中， 首先获取并缓存接收的红外线的强度值， 然后每当接收到外界的 红外线时， 读取接收的红外线的强度值， 根据读取的红外线强度值和缓存的红外线强度值 计算出差值， 根据计算出的差值和预设的第二阈值确定是否有物体接近终端。 其中， 对于 同一终端， 终端对每次接收的反射的红外线的强度值的影响都相同， 因此在计算读取的红 外线强度值与缓存的红外线强度值的差值时， 消除终端的物理结构的影响， 从而可以在每 个终端中设置相同的第二阈值， 并使每个终端都能精确地确定是否有物体接近。 实施例 5
