下面结合附图和具体实施例对本发明所述技术方案作进一步的详细描 述, 以使本领域的技术人员可以更好的理解本发明并能予以实施, 但所举 实施例不作为对本发明的限定。
本发明某些实施例提供的所述用于具有触控屏的电子设备的信息处理 方法, 在实现过程上分为信息的拾取过程和信息的显示过程两个部分, 这 里, 所述信息的显示过程也可以称为信息的输入过程, 在实施例中, 所述 信息通常是指图像信息, 图像信息的拾取过程是指: 从电子设备的屏幕上 拾取显示的图像或签名, 并将拾取数据予以保存的过程; 图像信息的输入 过程是指: 利用信息处理设备, 在电子设备的屏幕上选择适当的位置, 将 已经保存了的图像信息, 比如图像或签名, 直接喷涂在该位置作为标记的 过程。
这里, 需要说明的是: 本文所说的电子设备通常是指但不限于: 平板 电脑、 手机或个人数字助理(PDA, Personal Digital Assistant )等; 本文所 称的信息处理设备, 是指: 与所述平板电脑、 手机或 PDA配套使用的设备, 例如手写笔, 本发明实施例将以手写笔来详细叙述本发明的精神。
图 1为本发明一实施例采用手写笔拾取图像信息的示意图, 依照图 1 , 用以发送信息拾取命令的装置可以为手写笔, 也可以为电子设备, 对于信 息拾取区域的选择, 需要通过手写笔来进行, 电子设备对信息拾取区域里 的图像信息拾取完毕, 可通过以下两条途径进行存储:
1、 将所述图像信息通过 EM扫描、 红外传输、 蓝牙传输、 USB等传输 方式传输至手写笔上进行存储; 2、 将所述图像信息直接存储在电子设备上。
但是, 不管是进行上述何种存储方式, 当所述图像信息在进行存储之 前, 都可以对所述图像信息先行予以图像预处理, 例如压缩处理、 二值化 处理、 灰度处理、 以及边缘处理等, 以减少存储和传输的数据量, 加快操 作的响应时间。
图 2为本发明一实施例采用手写笔进行图像输入的示意图。 同样的, 发 出信息输入命令的装置可以为手写笔, 也可以为电子设备, 例如手机, 并 且当用户利用手写笔在电子设备的屏幕上选择了信息显示区域时, 会将用 户想要的图像信息显示在该区域。 值得注意的是: 依照图 2, 当采用上述存 储方式将图像信息存储在手写笔中时, 所述图像信息需要首先从手写笔上 传输至所述电子设备,可采用的传输方式包括:蓝牙、红外、近场通信(NFC, Near Field Communication ) 的传输方式, 也可以采用电场输出电路与电子 设备的电容屏或触控屏之间的信息交互方式, 也可以采用盖章方式; 其中, 盖章方式将在下文详细讲述。
图 3为本发明一实施例提供的手写笔的结构示意图, 如图 3所示, 整个 手写笔内部包括: 电源模块 101、 传输模块 104、 存储模块 102、 以及控制模 块 103; 其中,
电源模块 101 , 用于对其它各个模块的正常工作供电, 可以通过内置电 池实现, 也可以通过外部充电连接实现。
传输模块 104, 用于从电子设备上获取需要拾取的图像数据, 转交至存 储模块 102保存, 或者, 通过控制模块 103 , 将存储于存储模块 102中的图像 信息数据传输给电子设备。
存储模块 102 , 用于存储手写笔中的图像信息数据, 在控制模块 103的 控制下, 配合传输模块 104可实现将图像信息数据录入手写笔 10, 或者, 在 控制模块 103的控制下, 配合传输模块 104将手写笔 10中的图像信息数据输 出给电子设备。
当然, 该手写笔 10还包括输入笔尖, 所述输入笔尖是手写笔 10进行普 通输入的结构, 在本发明的实施例中, 可以起到在电子设备的屏幕上截取 图像或选择图像输出到电子设备屏幕上的指定位置的作用。
图 4为本发明实施例提供的手写笔进行图像信息拾取的操作示意图, 根 据图 4, 对应的图像拾取过程如下:
用户在移动终端 20上进行操作, 进入图像拾取模式。
用户使用手写笔 10, 在电子设备 20的屏幕 201上进行操作, 画出一个手 写笔操作线 208 , 移动终端以手写笔操作线 208作为对角线, 电子设备 20定 制以该对角线所作的矩形区域, 作为信息拾取区域 209, 当然信息拾取区域 209的定制可以有多种多样的方式, 例如: 用户可以将感兴趣的区域采用手 写笔 10进行圈定, 从而将所述圈定的区域作为信息拾取区域, 或者, 采用 基于图像处理的信息拾取方式制定信息拾取区域, 这里对上述定制方法不 做限定。
电子设备 20对信息拾取区域 209中的图像信息数据进行存储, 这样的优 点在于: ( 1 )可以省略手写笔 10的传输模块 104, 这样, 在一定程度上可以 节省成本; (2 ) 由于电子设备 20的存储容量更大, 可以在电子设备 20中存 储更多的图像信息, 从而供用户根据具体的应用场景选择。 但是, 直接将 图像信息存储于电子设备 20上还存在以下问题: (1 ) 用户在电子设备 20上 进行选择操作的过程较为复杂; (2 )手写笔 10在其它的电子设备 20上无法 进行同样的签名或标记, 缩小了用户的使用范围。
除此之外, 还可以通过该电子设备 20包括的信息传输模块向手写笔 10 的传输模块 104进行传输, 手写笔 10接收到图像信息后, 对该图像信息数据 进行存储, 采用该种存储方式, 可以克服上述的两个问题。
图 5为本发明实施例提供的手写笔进行图像信息输入的操作示意图, 根 据图 4, 对应的图像信息的输入过程如下:
用户在电子设备 20上选择添加标记或签名。
用户使用手写笔选择要喷涂标记或签名的点, 并点击屏幕 201。
电子设备 20的信息传输模块向手写笔的传输模块发送握手信息; 其中, 所述电子设备 20的信息传输模块具体可以是数据传输接口, 所述手写笔的 传输模块具体可以是数据传输接口。
手写笔的传输模块收到握手信息后, 将手写笔中存储的图像信息发送 给移电子设备 20的数据传输接口。
电子设备 20收到图像信息数据后, 将其显示在手写笔所指示的位置, 完成图像信息的显示或称喷涂过程。
图 6A为本发明实施例提供的图像信息拾取的方法流程图, 如图 6所示, 包括以下步驟:
5101、 准备;
5102、 用户在电子设备的某个界面下, 从电子设备操作用户界面(UI, User Interface )选择进入截图模式;
5103、 图像静止, 用户使用手写笔, 选择所需要截取的图像区域并截 图;
5104、 电子设备对截下的图像信息进行处理, 封装为标准图像格式;
5105、 将图像保存在电子设备或手写笔对应的存储模块中, 供后续输 入时调用;
5106、 结束。
图 6B为本发明实施例提供的图像信息输入的方法流程图, 如图 6所示, 包括以下步驟:
5201、 准备;
5202、 用户在电子设备的某个界面下, 从电子设备的操作 UI选择进入 贴图模式;
5203、 使用手写笔在电子设备的屏幕上选择需要贴图的位置;
5204、 从电子设备或手写笔中获取保存的截取的图像, 并选择需要贴 图的图像;
5205、 电子设备将该获取的图像喷涂在手写笔所选择的位置, 并保存 该处理结果;
5206、 结束。
在上述本发明实施例的具体实施过程中, 不少操作都是借助电子设备 来实现的, 在用户使用手写笔进行图像截取和输入时, 如果大部分操作能 够借助手写笔实现, 而不需用户在手写笔和电子设备之间切换操作, 必然 会有更好的用户体验。
基于此, 本发明的另一实施例提供了一种新的信息处理设备, 即: 手 写笔 10, 图 7为本发明另一实施例提供的手写笔的结构示意图, 如图 7所示, 该手写笔 10包括: 电源模块 101、 存储模块 102、 数据接口 106、 命令输入模 块 105、 控制模块 103、 以及电场输出电路 104组成; 其中,
电源模块 101 ,用于向手写笔 10中各部分供给必须的电量,可以是电池, 有线充电等模式。
数据接口 106 , 在本实例中特指 USB接口, 与存储模块 102相连, 在本 实例中用于将电子设备中的图像通过 USB等方式传递给手写笔 10的存储模 块 102存储。
命令输入模块 105 , 用于为用户提供命令的输入通道, 例如, 命令输入 模块 105可以包括若干个操作按键, 也可以包括从内存中选择图像的操作按 键, 向电子设备输出图像的控制按键, 甚至还可以包括控制手写笔 10启动 截图操作的按键等等。
控制模块 103 , 是整个手写笔 10的中心控制单元, 主要用于: 将命令输 入模块 105的操作翻译成发射信号的调制信息, 传递给电场输出电路 104; 并按照用户的操作, 将选择的图像进行编码, 发送给电场输出电路 104。
电场输出电路 104, 用于将控制模块 103发送过来的调制信息及编码后 的图像, 输出相适应的电场给电子设备的触控屏。
使用图 7所述的手写笔, 与电子设备进行图像拾取及输入的过程如下: 图像拾取过程:
用户通过手写笔上的操作按键操作手写笔, 向电子设备的触控屏发送 信息, 控制电子设备进行截图; 其中, 所述触控屏为电容屏, 包括: 电容 检测器件。
电子设备截图后, 通过数据接口将截取的图像信息传输给手写笔, 手 写笔将所述截取的图像信息进行存储。
图像输入过程:
用户通过手写笔上的操作按键操作手写笔, 向电子设备的触控屏的电 容检测器件发送相应信息。
电子设备收到该信息后进行处理准备, 比如: 冻结当前图像等。
手写笔从自身的存储单元中调取出相应的图像信息, 由控制单元进行 调制编码后, 发送给所述电场输出电路, 并控制电场输出电路向电子设备 的触控屏的电容检测器件发送相应的图像信息。
电子设备通过触控屏的电容检测器件的变化识别出图像信息。
电子设备将获取的图像信息显示在手写笔所指定的位置。
在上述实施例中, 电场输出电路的图像信息数据的输出方式可以为串 行, 也可以为并行。 串行方式为: 只向一点电容检测器件进行输入, 输入 完一个像素, 再输入一个像素, 该方式所需时间较长, 但结构简单, 手写 笔采用普通的笔尖结构即可。
并行方式类似于盖章, 如图 8所示, 即: 手写笔进行图像信息数据输入 的部分类似于印章形状, 印章面上分为若干个像素输出单元, 像素输出单 元的密度可以参考电子设备的触控屏的电容检测器件的密度, 形成当将该 类似于印章的手写笔盖到电子设备的屏幕上时, 一个像素输出单元刚好可 以对应一个电容感应器件。
如图 8所示, 当手写笔的印章面盖到电子设备的屏幕上, 且启动图像信 息数据输出后, 每个像素输出单元仅仅负责将自身所在的小图像区域的图 像数据传输给对应的电子设备的电容检测器件。 手写笔汇总整个印章区域 的电容检测器件分别收到的图像数据, 经过排列处理, 形成整个图像显示 出来, 这样, 较大的节省了传输时间。 另一方面, 操作体验与盖印章十分 相似, 比较符合用户的使用习惯。
以上所述仅为本发明的优选实施例, 并非因此限制本发明的专利范围 , 凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换, 或直 接或间接运用在其它相关的技术领域, 均同理包括在本发明的专利保护范 围内。
