为了更了解本发明的技术内容, 特举具体实施例并配合所附图式说明如下。 图 3和图 4为本发明实施例所提供的扫描复印设备的整体结构示意图。 图 5 为本发明实施例所提供的扫描复印设备的内部结构示意图。 如图 3、 图 4和图 5 所示, 该扫描复印设备包括壳体 200和盖 201 , 以及设置在壳体 200内的扫描器、 透明承载板 203和图像攫取单元 207。 该扫描器由托架 204以及设置在托架 204 上的扫描模组 206和图像攫取单元 207组成, 用以扫描以获得扫描对象的图像。 该托架 204可移动地支撑在壳体 200内。透明承载板 203为一个有机玻璃或玻璃, 用于放置扫描对象。 壳体 200上设置有扫描键 202a和复印键 202b, 分别连接至一控制部 208,扫 描键 202a和复印键 202b可从外部接近地操作并分别用于设定扫描复印设备的扫 描功能模式和复印功能模式。
如图 5所示, 扫描模组 206包括线性光源 206a、 反射镜 206b和透镜 206c, 线性光源 206a由至少一个 LED发光元件组成, 向放置在透明承载板 203上的扫 描对象发射光线, 经过扫描对象反射后,再以反射镜 206b反射扫描对象反射的图 像, 该反射镜 206b的位置经适当的安排, 可顺利地接收扫描对象反射的图像,并 将图像经透镜 206c, 传送至一图像攫取元件 207, 图像攫取元件 207利用光电转 换原理, 将扫描对象的图像转换成数位信息以进行输出。 本实施例中, 图像攫取 元件 207为一个电荷耦合元件( CCD )。
扫描复印设备的控制部 208, 连接一个驱动装置 209, 控制部 208控制驱动装 置 209驱动托架 204来回运动, 使扫描模组 206向前或向后移动, 以对扫描对象 进行完全扫描。
壳体 200内的透明承载板 203前端还设置有一校正板 205 , 校正板 205的颜 色是黑白相间, 或者是标准白、 标准黑。 当扫描键 202a触发并选择扫描功能模式 下, 在正式扫描前, 控制部 208将控制扫描模组 206和图像攫取单元 207执行校 正动作 (calibration ), 扫描校正板 205并将反射之图像传送至图像攫取单元 207, 经过计算后获得一个校正参数, 并存储于第一存储器 210内, 用于对扫描器正式 扫描扫描对象所获得图像进行校正和补偿, 以获得较高品质、 高保真度的图像。 第一存储器 210为一随机存储器(RAM ), 用于扫描复印设备作业过程中暂时性 的数据存储。
扫描复印设备还包括一个网络连接单元 211 , 例如一个 Wifi装置、 3G模块或 蓝牙模块, 将扫描复印设备接入网络, 将前述扫描功能模式下获得的校正参数上 传至网络存储空间, 例如一云存储服务器, 对校正参数进行存储。
当复印键 202b触发并选择复印功能模式下,扫描复印设备将不再通过扫描校 正板 205而获得校正参数, 而是由控制部 208控制从前述的网络存储空间下载所 存储的既有扫描的校正参数, 如前一次扫描操作的校正参数, 并利用该前一次扫 描的校正参数对扫描器进行校正。 如果扫描复印设备是出厂后的第一次使用, 并 无既有扫描的校正参数存在, 此时, 控制部 208控制读取扫描复印设备出厂时预 设的校正参数, 并基于该预设校正参数对扫描器进行校正。 对于预设校正参数, 可以在出厂前以只读方式存储在只读存储器(ROM )或系统档案中(图中未示出 ), 或者出厂前将该预设校正参数上传至网络存储空间, 这里的只读存储器(ROM ) 和前述的随机存储器(RAM )可与控制部 208集成设计, 例如构成一集成处理中 心, 这些都是常用的技术手段, 故不再赘述。 因此, 在执行复印功能时, 可大幅 节约因校正动作而浪费的等待时间, 提高复印作业的效率, 尤其是大量的数据复 印作业场合。
扫描器扫描获得的扫描对象的数位信息, 经过预定的处理, 传输至一图像形 成部 212, 或者通过图像输出部 213被发送至 PC、 USB闪存盘等外部设备, 该图 像输出部 213包括多种传输接口, 例如通过 Email、 USB接口等方式将数位信息 发送出去。 在该图像形成部 212中, 例如, 利用电子照相系统将图像形成在例如 纸张等记录介质上, 并从壳体 200的出纸口 220输出。 有利地, 该出纸口 220外 部还可以设置一个可折叠的支承板(未示出),用以支承从出纸口 220输出的纸张, 防止掉落。
在另外一些实施例中, 扫描复印设备还可以设置一个第二存储器(未示出), 例如一个非挥发性随机存储器, 连接至控制部 208。 在复印功能模式下, 控制部 208控制扫描模组 206和图像攫取单元 207获取的校正参数存储于该非挥发性随 机存储器内。 在复印功能模式下, 控制部 208控制从该非挥发性随机存储器读取 其所存储的既有操作(扫描或复印) 的校正参数, 例如上一次操作获得的校正参 数, 或者获取一预设校正参数, 对扫描器进行校正。
在本发明一实施例中, 该控制部 208包括: 校正参数获取模块、 扫描控制模 块。 校正参数获取模块与第一存储器 210或第二存储器连接, 扫描控制模块与扫 描模组 206连接, 根据获取的校正参数对扫描器进行校正。 该控制部还包括校正 参数存储模块, 同样与第一存储器 210或第二存储器连接, 用于将控制扫描模组 206和图像攫取单元 207获取的校正参数存储在第一存储器 210或第二存储器中。 本领域技术人员可以理解, 控制部的三个模块既可以是软件实现的, 也可以由硬 件实现。 如果是软件实现, 其可以是一段写入控制器处理器的程序段。 本领域技 术人员可以理解, 在本发明一实施例中, 该扫描复印设备可以同时包括多个存储 器 210, 且存储器的类别可分别为只读存储器(ROM )、 随机存储器(RAM )或 网络存储空间, 这样可实现校正参数的多方位存储, 当从其中一个存储器获取校 正参数失败时, 还可从其他存储器获取校正参数。
图 6为本发明实施例所提供的扫描校正方法的流程图。 如图 6所示, 该方法 包括: 当感应到待复印或扫描对象时, 首先判断是否需要执行校正, 如果执行校 正, 则扫描校正板, 获取校正参数, 将获取的校正参数存储在本地存储器中; 同 时判断扫描复印设备是否联网, 如果已经联网的话, 进一步将获取的校正参数上 传至网络, 然后进入校正数据使用流程。 如果不需要执行校正, 则直接进入校正 数据使用流程。
在使用校正参数时, 先从本机读取校正参数, 如果读取失败, 继续从网络读 取校正参数; 如果再次读取失败, 则获取缺省校正参数值(预设校正参数); 最后 根据成功获取的校正参数或缺省校正参数执行相应的复印或扫描动作。
在本发明一实施例中, 根据需要也可以没有本地存储器, 获取的校正参数直 接存储到网络存储器中。
在本发明一实施例中, 根据以下原则来判断是否需要执行校正: 根据作业类 型确认, 如果是扫描操作, 执行校正; 如果是复印操作, 则不执行校正。 或者根 据待处理对象的类型确认, 如果是图像, 则执行校正; 如果是文字, 则不执行校 正。 或者根据用户的手动选择确认。 或者判断已存储的校正参数中是否存在与当 前带处理对象对应的校正参数, 如果存在, 则不执行校正; 否则, 执行校正。 或 下面以根据作业类型选择是否执行校正为例说明本发明的扫描复印校正方 法, 如图 7所示, 该方法包括:
当用户提供一待处理对象放置在透明承载板上, 判断用户按下的是扫描键还 是复印键。 如果按下的扫描键, 由于对扫描效果的要求较高, 需要针对不同的扫 描对象设定不同的校正参数, 则扫描器扫描校正板获得校正参数, 并将该校正参 数作为既有扫描的校正参数储存于存储器中或上传到网络; 并基于该校正参数对 扫描器进行校正, 完成扫描。
如果按下的复印键, 从存储器或者网络中查询是否存储有既有扫描的校正参 数(在另一些实施例中为判断非挥发性随机存储器中是否存储有既有扫描的校正 参数), 如果判断为是, 如扫描复印设备不是出厂后的第一次使用, 则控制部 206 控制从存储器或者网络获得一个存储的既有扫描的校正参数, 并基于该既有扫描 的校正参数对扫描器进行校正。 该既有扫描的校正参数优选为上一次扫描功能下 获取并存储校正参数。 如果判断存储器或者网络中未存储既有扫描的校正参数, 比如扫描复印设备为出厂后的第一次使用, 则控制部 206控制获取一预设校正参 数, 并基于该预设校正参数对扫描器校正。 由以上本发明的技术方案可知, 本发 明的扫描复印设备和扫描校正方法可根据用户实际选择的功能需要, 在正式扫描 动作前, 执行校正动作或者不执行校正动作以获取一个校正参数, 对扫描器进行 校正, 缩短复印操作时的扫描时间, 提高使用效率。
以上说明书对较优实施例的解释和说明, 不以任何形式对本发明构成限制和 限定, 本发明的范围以权利要求书为准, 一切不超出本发明宗旨的显而易见的修 改、 变换和替代方案均在本发明范围内。
