Description

数字切片图像存储方法及装置、 电子图书显示方法及装置 本申请要求于 2013年 2月 8日提交中国专利局、申请号 201310050964.2、 发明名称为 "有源矩阵显示面板的驱动方法及驱动装置、 显示器 "的中国专利 申请的优先权, 其全部内容通过引用结合在本申请中。
技术领域
本发明涉及数字信息处理技术,特别涉及一种数字切片图像存储方法及装 置、 电子图书显示方法及装置。
背景技术
随着计算机技术的发展,各种信息的数字化存储已逐渐为人们所使用, 当 今社会的庞大信息在各行各业都出现了不同程度的信息浪费、 信息堵塞等问 题, 海量信息的存储、 分析、 处理等方面都值得人们深入研究。
各种信息中, 文字信息及图像信息是使用率最高的信息。但图像信息作为 信息载体往往比文字信息能够表达更多的信息量。 然而, 随着人们不断提高对 图像质量、 精度等性质的要求, 大容量图像信息的存储、 分析、 处理等方面的 管理已不容忽视。
在病理学方面尤为如此, 病理切片 (玻璃切片)是病理标本的一种; 传统 的病理切片在制作时一般将部分有病变的组织或脏器经过各种化学品和埋藏 法的处理, 使之固定硬化, 在切片机上切成薄片, 粘附在玻璃片上, 染以各种 颜色, 供在显微镜下检查, 以观察病理变化, 做出病理诊断, 为临床诊断和治 疗提供帮助。数字切片图像则是将病理切片进行数字化处理的结果; 在数字切 片图像上包含有病理切片的所有图像信息,使用者可以在计算机或者其他服务 终端上观察数字切片图像, 而无需借助显微镜。
然而,数字切片图像因数据产生设备的精度及质量的提高, 其分辨率是很 高的, 因此数字切片图像携带的信息量是庞大的。现有技术的医学类电子图书 或网络图书(电子版的书籍)也采用切片图像作为其显示图片, 但与传统的印 刷书籍类似的是, 当书籍中涉及到切片图像时, 电子图书仅保存局部切片图像 元素并固定显示该图像元素形成的局部切片图像,局部切片图像本质上是数字 切片图像非常微小的一部分, 为了弥补显示不清的缺陷(无法观察到周围的切 片图像信息),现有技术一般选取多张不同位置的局部切片图像进行固定显示。 上述这种切片图像存储与显示方式造成了切片信息的不完整,即实际切片所包 含的信息是庞大的,但真正在电子书籍内存储与使用的切片信息却仅是局部的 切片信息, 这种切片图像的存储与显示方式造成了切片信息的浪费。 发明内容

具体实施方式
电子图书(或功能同电子图书的电子产品、电子应用,如网络在线书籍等) 相对于传统纸质的书籍, 具有即时更新、 便于查询、 使用直观的优点。
数字切片图像是病理学中显微学科观察且做出结论的重要依据,医学类电 子图书中常常需要以切片图像作为内容进行显示,但因数字切片图像承载的切 片信息是完整的, 其数据量非常大,将数字切片图像庞大的信息全部加载到电 子图书内是不切实际的。传统的医学类电子图书仅是以承载部分切片信息的切 片图像作为其图像内容, 而不选用也非存储完整的数字切片图像。 换句话说, 现有技术的电子图书仅截取了局部切片图像进行显示,但如此承载的切片信息 非能完整呈现切片组织, 因而选取了多个局部切片图像进行显示, 即以多图的 方式进行显示,但这也导致了电子图书内大量的图像排版; 上述局部切片图像 仅仅是固定显示, 不仅对于切片信息的承载量小, 造成切片信息的浪费, 也无 法直观地观察切片的其他部分, 信息反馈性能很差。
针对以上问题,发明人想到,数字切片图像是能够承载完整的切片信息的, 如果可以实现电子图书对于数字切片图像的充分利用,应当可以实现电子图书 对于切片信息的完整呈现。现有技术是固定显示切片图像的, 若能够将切片图 像于电子图书的图像显示窗口动态地显示, 不仅会解决图像排版复杂的问题, 也能够使用户直观地观察切片图像。
基于以上思路,发明人首先在本发明技术方案中定义了一种新的数字切片 图像的存储结构, 该种存储结构不仅能够支持大容量的数字切片图像,还采用 如下方式对切片的图像元素信息进行处理:对图像元素信息进行以设定的分级 倍率进行分级, 并对分级后的图像元素信息进行分割, 形成对应分级倍率的数 字切片图像, 且对应分级倍率的数字切片图像被分割为若干子数字切片图像。 此外,发明人还公开了一种支持上述存储结构的电子图书的显示方式,通过获 取用户请求中携带的显示倍率及显示位置的信息,读取与所述显示倍率的相关 的部分数字切片图像, 关于数字切片图像具体选择区域, 则与显示位置信息有 关。
实施例 1
如图 1所述的一种数字切片图像的存储方法, 包括:
步骤 S1 : 获取切片的图像元素;
切片的图像元素是根据显示单位对以标准倍率放大切片所得的切片图像 进行分割所得到的, 具体地, 获取切片的图像元素是基于如下步骤完成的, 可 参见图 2:
步骤 S101 : 利用放大观察装置获取切片上选择范围内的高倍率的放大图 像;
步骤 S102: 利用相机将选择范围内的放大图像记录下来, 形成切片范围 内的面图像;
其中, 面图像的尺寸是由所述相机既定的;
步骤 S103: 重复步骤 S101~S102, 依次获取整个切片 (即切片全部范围 内) 的面图像;
步骤 S104: 依据预先设定的尺寸对所有获取的面图像拼接形成的切片图 像进行再分割, 形成所述切片的图像元素。
步骤 S101所述的放大观察装置可以是显微镜。
步骤 S102的在放大观察装置所选择的切片范围内用相机记录面图像的过 程如下, 具体可参考图 3:
图 3示意了放大观察装置所选择的切片范围 (为部分切片), 将该切片依 据显示单位划分为由显示单位 1~99组成的切片图像, 其中, 所述显示单位可 以是像素或其他用于显示衡量单位。 图 3的 C部分示意了所述面图像, 即包 括显示单位 1、 2、 11、 12。
关于步骤 S104, 切片的图像元素, 是对面图像拼接形成的切片图像进行 重新分割所形成的, 其目的在于使所存储的图像元素更为贴近显示图像的要 求, 比如, 以图 3所示意的切片范围为例, 假设面图像拼接得到的切片图像为 1-99显示单位所构成的, 而此时的显示单位为一个像素, 那么再次分割所得 到的图像元素可以是包括了显示单位的图像信息的切片图像的存储单位,即包 括了一个像素的切片图像的信息。
上述过程还具体可以用如下算式进行计算:
若面图像尺寸为 Χχ Y (X、 Y对应至少两个显示单位), 最终获得的图像 元素的设定尺寸为 ΜχΝ (Μ、 Ν对应至少一个显示单位), 可以通过如下过 程, 实现从面图像到图像元素的获取过程:
Sal, 横向拼接 m个连续面图像, 纵向拼接 n个面图像, 取( m x X ) /M 的整数部分 i ( i > 1 ), 取( n x Y ) /N的整数部分 j (j>l), 并从面图像拼接形 成的图像顺序截取前 i个 M X N的显示单位(可以是像素)作为 i个图像元素; 上述过程中, 有 m、 η>1, n、 m为根据显示要求预先设定的整数。
Sa2, 重新将横向拼接剩余部分(mxX _ ixM) χΥ作为第一个面图像 并重复步骤 Sal, 直到相同纵向位置的剩余横向图像元素不足 M个显示单位 为止。
Sa3, 将步骤 Sal的纵向拼接剩余部分 Χχ ( η χ Υ- j χ Ν )作为第一个面 图像并重复步骤 Sal~ Sa2。
Sa4,重复步骤 Sal~Sa3,直到纵向剩余部分的图像元素不足 N个像素为止。 步骤 S1得到的整个切片的图像元素具体可以是以特定的图像格式存储, 其所对应的是高倍率的数字切片图像。
步骤 S2: 对属于同一切片的图像元素执行处理步骤; 所述处理步骤用于 以设定的多个分级倍率形成对应分级倍率的数字切片图像,且不同分级倍率的 数字切片图像被分割为若干子数字切片图像。
这里, 步骤 S1与步骤 S2之间还包括一个数据处理过程, 具体地, 在相机 记录每一个图像元素时,会对图像元素进行编号,属于同一切片的图像元素是 属于同一序列组的。 因此, 在对图像元素执行处理步骤之前, 还包括对获取的 切片图像元素进行归类的步骤, 对以同一序列组顺序编号的数据(图像元素) 存放在同一地址下,即被标记同一序列组顺序编号的数据是从同一切片上被记 录下来的图像元素,对图像元素进行的编号可以是文件名的形式,也可以是图 像元素所存储地址的标记信息; 对应的, 属于同一序列组的编号, 可以是符合 一定规则的文件名的序列, 比如 IMAGE00UPEG、 IMAGE002. JPEG... ,还可 以是同一地址下的图像元素, 比如其标记信息均是 D:\My Documents \My PicturesMmageOOOl o 并且, 这里的处理步骤是一个图像元素的处理过程, 旨在 基于原始切片数据 (获取的图像元素)构建出对应不同分级倍率的数字切片图 像, 而生成的数字切片图像还以图像元素为存储数据,被分割为若干子数字切 片图像, 其存储的数据是对应每个子数字切片图像的图像元素。
如图 4所示, 处理步骤进一步可以用如下步骤实现,:
步骤 S201: 将属于同一切片的图像元素分割成若干子图像元素; 在本步骤中,图像元素与子图像元素分别是对应数字切片图像的图像元素 与对应子数字切片图像的图像元素, 其都是上述定义的图像元素。
步骤 S202: 分别以设定的多个分级倍率缩小所述子图像元素, 以获得对 应分级倍率的子图像元素;
除了上述分级倍率外, 图像元素(子图像元素)还存储着最高倍率, 即是 步骤 S1所得到图像元素对应的数字切片图像局部的倍率。
所述以设定的多个分级倍率缩小所述子图像元素可以具体是对图像元素 中显示单位的线性缩小,也可以是对显示单位的其他调整方式,在实际实施时, 对显示单位的调整可以是对图像像素的调整,因属于常规技术,此处不再赘述。
步骤 S203: 依据对应分级倍率的子图像元素形成子数字切片图像, 所述 子数字切片图像拼接为对应分级倍率的数字切片图像。
步骤 S3: 将所述数字切片图像进行存储。
根据步骤 S1~S3, 所形成的存储数字切片图像的文件格式, 包括: 头文件信息, 定义了所存储的数字切片图像的全局信息, 进一步包括: 数据基本信息: 包括数据总长等。
版本信息;
切片图像的全局信息: 包括图像宽高, 压缩方式, 标签信息, 扫描倍率, 扫描时间;
子切片图像的分级索引信息:包括形成的各子数字切片图像所存储相对位 置、 各子数字切片图像之间的分级及分割关系;
其他标记信息。
子图像元素信息, 进一步包括:
子图像头文件信息, 包括所在子切片图像的相关信息, 如: 子切片图像的分级编号信息;
子切片图像的数据长度信息;
子切片图像的坐标信息;
子切片图像的其他标记信息;
子图像元素的数据信息, 包括子图像元素的数据信息。
实施例 2
一种数字切片图像的存储方法, 包括:
与实施例 1相同的步骤 S1~S3。
与实施例 1不同的是,如图 5所示, 步骤 S1具体是基于如下步骤完成的: 步骤 S301 : 使用放大扫描设备逐点地扫描切片, 并获取切片的点图像; 由于逐点地扫描到的图像数据已是基于最小显示单位,故而, 这里的点图 像可以直接作为图像元素进行采集。
步骤 S302: 重复步骤 S301 , 依次获取整个切片 (即切片全部范围内) 的 点图像;
步骤 S303: 基于上述点图像形成所述切片的图像元素。
当然, 在其他实施例中, 步骤 S301也可以采用放大扫描设备逐行或逐列 地扫描切片, 并获取切片的行图像或列图像。
由于本实施例的点图像(行图像或列图像)等同于实施例 1尺寸为 1 x 1 ( Χ χ 1或 1 X Y )的面图像, 其具体实施过程及算法可参考实施例 1 , 本实施 例不再赘述。
除了上述不同点外, 本实施例还有一个与实施例 1不同的实施方式在于: 如图 6所示, 本实施例的步骤 S2的处理步骤包括:
步骤 S401 : 分别以设定的多个分级倍率缩小属于同一切片的图像元素, 以获得对应分级倍率的切片图像元素;
步骤 S402: 将对应各分级倍率的切片图像元素分别分割成若干子图像元 素;
步骤 S403: 依据对应分级倍率的子图像元素形成子数字切片图像, 所述 子数字切片图像拼接为对应分级倍率的数字切片图像。
实施例 1与实施例 2所述不同分级倍率均不包括标准倍率 (即步骤 S1所 获取图像元素对应的数字切片图像的倍率 ), 所述分级倍率认为是小于标准倍 率的预设倍率, 比如, 标准倍率为 20, 分级倍率可为 1、 2、 5、 10。
当然, 在其他实施例中, 所述分级倍率可以包括标准倍率, 此时, 分级倍 率相当于一个倍率信息的概念, 可分为标准倍率与其他倍率(其他倍率均小于 标准倍率 ),那么步骤 S401可适应性变化为: 分别以设定的分级倍率中的其他 倍率缩小属于同一切片的图像元素, 以获得对应其他倍率的切片图像元素; 步 骤 S202可适应性变化为: 分别以设定的分级倍率中的其他倍率缩小所述子图 像元素, 以获得对应其他倍率的子图像元素。其实与实施例 1与实施例 2应属 于同一技术范围内。
本实施例最终所形成的存储数字切片图像的文件格式与实施例 1一致,此 处不再赘述。
实施例 3
对应于实施例 1和实施例 2, 本实施例给出了一种如图 7所述的电子图书 的显示方法。本实施例的电子图书被嵌入基于实施例 1或实施例 2的存储方法 所形成的存储文件, 能够在显示界面上加载和显示数字切片图像。
图 7的电子图书的显示方法包括:
步骤 Ml: 获取用户的第一请求, 所述第一请求携带显示倍率及显示位置 的信息;
根据本步骤,首先要确定用户所选择的图像的显示倍率及希望现实的切片 位置信息。 一般地, 用户可以通过输入数据, 如操作鼠标、 键盘或其他程序图 形等来要求显示图像, 并设定当前图像的显示倍率及显示位置。 当然, 还可以 通过调整显示窗口的大小,这样既携带了显示倍率信息也确定了显示位置信息 (显示窗口显示的图像本身已确定了显示位置,可以通过当前窗口长宽长度与 用户调整的窗口的长宽长度的比值推算用户所需的显示倍率)。
步骤 M2: 读取与所述显示倍率的相关的部分数字切片图像, 部分数字切 片图像的选择与所述显示位置相关;
在步骤 M2中, 如图 8所示, 若用户的第一请求中所携带的显示倍率等于 多个分级倍率或标准倍率中的任一个,所述读取对应所述显示倍率的部分数字 切片图像还进一步包括步骤: 步骤 M201: 选择对应所述显示位置的子数字切片图像;
步骤 M202: 读取所选择的子数字切片图像中对应所述显示倍率的子数字 切片图像;
步骤 M203:将所读取的子数字切片图像拼接形成所述部分数字切片图像。 当然, 如图 9所示, 在步骤 M2中还可能遇到用户的第一请求中所携带的 显示倍率不等于多个分级倍率或标准倍率中任一个的情况,此时所述读取对应 所述显示倍率的部分数字切片图像还进一步包括步骤:
步骤 M301: 选择对应所述显示位置的子数字切片图像;
步骤 M302: 确定与所述显示倍率最接近的分级倍率或标准倍率; 步骤 M303: 读取所选择的子数字切片图像中对应所述最接近的分级倍率 或标准倍率的子数字切片图像;
步骤 M304: 调整所读取的子数字切片图像的倍率至显示倍率;
步骤 M305:将调整后的子数字切片图像拼接形成所述部分数字切片图像。 步骤 M3: 在图像显示区域显示所读取的部分数字切片图像。
所述图像显示区域即上述显示窗口。
由于电子图书除了图像部分还包括文字部分, 本实施例还可以包括步骤
M4:
基于用户的第二请求读取文字信息;在文字显示区域显示所读取的文字信 息。
当然, 除了上述切片图像的显示文字的显示, 本实施例的电子图书可以根 据用户请求或系统初始化加载显示除切片图像以外的其他图像信息。

其他信息存储单元 400;
显示服务端 500, 实现如下步骤:
通过互联网接收用户的在客户端 100操作用户阅读界面所发出的第一请 求, 第一请求可以由用户操作鼠标、键盘等硬件输入并开启客户端 100用户界 面上的特定图标或链接等发出的,指示用户要求在图像显示区域 102的显示窗 口显示图像, 当然, 同时也可用调整图像显示区域 102的显示窗口的方式(具 体可参见本实施例;),在第一请求中加载并使之携带显示倍率及显示位置请求。
选取倍率信息及位置信息与第一请求中所携带的显示倍率及显示位置请 求相匹配的显示单元, 并通过调取该显示单元的地址信息指向的图像元素(获 取相应倍率的子数字图像显示单元的图像元素); 再通过互联网反馈至客户端 100, 并在图像显示区域 102的显示窗口显示该图像;
当然,这里所谓选取倍率信息与第一请求中所携带的显示倍率请求相匹配 的显示单元, 是有两种情况的 (具体参见实施例 3 步骤 M201~M203、 步骤 M301-M305 ): 根据显示要求, 在选定显示单元后, 将该显示单元中的图像元 素调整为要求的倍率,例如仅包括存储对应 10倍倍率和 15倍倍率图像元素的 两个显示单元, 那么对于用户请求中携带的 14倍倍率的显示要求会使用对应 15倍倍率图像元素的显示单元, 并且,显示服务端 500还对传递至客户端 100 的图像元素进行调整, 缩小至 14倍倍率后再行传递。 当然, 也可选择对应 10 倍倍率图像元素的显示单元,但有可能会产生显示图像失真的问题,故以选择 对应高倍率的显示单元为宜。
此外,选取位置信息与第一请求中所携带的显示位置请求相匹配的显示单 元,也非仅选取一个显示单元, 因为用户给出的位置信息往往是以点的形式出 现的, 用户选择的点, 是图像上坐标点的概念。 对于单个图像元素来说, 其是 显示单位, 比如一个像素的范围 (参见实施例 1对应图像元素的论述部分), 因此,是根据用户给出的点信息是否落入显示单元的坐标信息(也是位置信息) 所限定的范围内判定的; 再有, 由于显示窗口的长宽长度是用户调整的, 其相 对的长度加上用户选择的点, 限定了所需的部分数字切片图像; 根据这部分数 字切片图像上所有点 (坐标点的概念), 选择包含上述点的对应一定倍率信息 的至少一个显示单元, 这些显示单元所指向的图像元素构成的子数字切片图 像, 拼接形成显示的部分数字切片图像。
至于文字信息存储单元 300、 其他信息存储单元 400在客户端 100的文字 显示区域 101或图像显示区域 102的请求显示, 可与上述过程类似, 当然, 由 于文字信息数据量较小,也可以直接一次性请求加载到客户端 100并在文字显 示区域 101的显示窗口显示。
设置显示服务端 500, 是由于数字切片图像所存储的数据量较大, 显示单 元数目众多, 一次性加载及显示至客户端 100不利于数据管理, 因一些数据对 于特定用户是非必要的, 出于用户特定化的问题, 对于单个用户, 数字切片图 像的一次性加载及显示反而会造成数据的浪费。
本发明虽然已以较佳实施例公开如上,但其并不是用来限定本发明,任何 本领域技术人员在不脱离本发明的精神和范围内,都可以利用上述揭示的方法 和技术内容对本发明技术方案做出可能的变动和修改, 因此, 凡是未脱离本发 改、 等同变化及修饰, 均属于本发明技术方案的保护范围。
