一种选择立体成像视点对的方法，包括： 从两个或更多立体成像视点对中的每一对接收对象场景的视差范围的提示，；其中所述对象场景的视差范围与所述对象场景中最近对象和最远对象的视差的差相关； 接收立体显示器的视差约束的提示，其中所述立体显示器的视差约束的提示包括所述立体显示器的最大视差范围的提示；和选择其视差范围最大并且其视差范围小于所述立体显示器的最大视差范围的立体成像视点对。

作为一名经验丰富的专利代理师，我将针对目标专利（CN102835116B）的权利要求1，结合说明书及提供的四份对比文件（D1-D4）进行深入的侵权/无效分析。

### 一、 权利要求特征分解与说明书解释

根据目标专利说明书的记载，权利要求1的技术实质是通过对多个候选视点对进行“视差筛选”，在满足显示器舒适度限制的前提下，自动选择一个能提供“最深”立体感（即视差范围最大）的视点对。

* **技术特征A（接收多对视差范围提示）：** 说明书[0048]-[0058]解释了立体成像视点对（SIVP）可以具有不同的分离距离（如2.5cm, 4cm, 6.5cm），每对对应一个特定的视差范围。

* **技术特征B（视差范围定义）：** 说明书[0065]-[0066]明确指出，视差范围是场景中最近对象（$D_{max}$）和最远对象（$D_{min}$）视差之间的差分度量。

* **技术特征C（显示器约束）：** 说明书[0010]和[0078]指出，约束源于显示器的物理限制及人体工程学（舒适查看参数），通常表现为一个固定的像素范围。

* **技术特征D（选择逻辑 - 最大且小于约束）：** 这是本发明的核心。说明书[0004]强调，选择“最大”视差是为了增强3D效果和扩展视深，而“小于约束”是为了消除眼疲劳。

### 三、 对比文件详细分析

#### 1. D1 (GB2354389A) 与 D3 (EP1089573A)

这两份文件属于同一技术体系（D3为D1的同族或高度相关申请），主要解决将场景深度映射到显示器舒适深度范围的问题。

* **对特征A、B的公开：** D1在第10-11页明确给出了场景参数 $N'$（最近距离）和 $F'$（最远距离），并结合相机参数（基线、焦距等）计算视差。更关键的是，D1在第17-18页提出了“预设参数集”（Precalculated sets），涵盖了“远景”、“中景”、“近景”等多个类别。这实际上就是提供了多个可选的视点配置方案。

* **对特征C的公开：** D1在第10页列出了显示器参数 $N$、$F$（最大感知深度），并在第11页将其转换为屏幕视差 $dN$、$dF$。

* **对特征D的公开：** D1在第18页指出：“估算适当的深度范围，以确保场景中实际存在的所有深度都在上述大类的限制之内（within the limits of the broader categories）”。虽然未明文使用“选择最大的一个”这种表述，但在摄影和立体显示领域，在不引起疲劳的前提下追求最强的3D效果（即最大基线）是公知常识。D1提供的分类选择机制在逻辑上必然指向“在满足限制的分类中选择效果最好的一个”。

#### 2. D2 (GB2354391A) 与 D4 (JP2001142166A)

这两份文件侧重于带有视差警告功能的3D相机。

* **对特征A、C的公开：** D2在第11页提到电路24接收显示几何参数（尺寸、观察距离），并在第20页提到根据不同的显示器（如20英寸或不同尺寸范围）进入菜单选择不同的参数。

* **对特征D的公开：** D2更强调通过调整单对相机的基线或焦距来适配限制，而非从多对中“选择”。但在第20页的实例中，它提到了根据场景（风景、中景、微距）预设不同的基线参数（Object parameter $\alpha$）。当场景变化时，系统会提示或自动调整以适配。

### 四、 最接近对比文件分析

在创造性分析中，**D1 (GB2354389A)** 最适合作为**最接近的对比文件**（第一最接近对比文件）。

* **理由：**

1. **技术领域一致：** D1和目标专利都关注立体图像生成中“场景深度”与“显示器舒适限制”的匹配。

2. **解决的技术问题相同：** 两者都旨在避免观看疲劳，同时优化立体感。

3. **技术手段最为接近：** D1明确提出了“预设多个参数类别”供选择的方案（p17-18），这与目标专利的“从多个视点对中选择”在本质上是相同的技术构思。D1已经公开了接收显示器约束（特征C）和根据场景深度（特征B）在多个预设方案中匹配（特征A、D）的过程。

**D2 (GB2354391A)** 可作为第二最接近对比文件，因为它公开了基于自动对焦获取场景范围并结合显示器限制进行参数预设的硬件实现方式。

---

### 五、 无效请求的最薄弱技术特征分析

若提出无效请求，目标专利最具争议且最薄弱的特征在于：**特征D中“选择最大”的限定。**

**理由如下：**

1. **公知常识的必然性：** 在立体成像领域，视差越大，立体感越强。在已知显示器存在视差上限（约束）的情况下，为了获得最佳成像质量，本领域技术人员在多个备选方案中自然会选择那个“在限制范围内所能达到的最大值”。这属于典型的“从已知方案中选择效果最佳者”，其技术效果是可以预期的。

2. **D1的隐含公开：** D1第18页的分类选择（Distant, Far, Midrange, Close range）本质上就是一种阶梯式的方案。如果场景深度属于Midrange，技术人员不会去选择效果更弱的Distant方案，而是会选择能覆盖该范围且最接近限制上限的方案。目标专利只是将这种隐含的逻辑选择过程显性化、自动化了。

3. **创造性辩驳点：** 专利权人可能会辩称“自动化选择”提高了效率。但D1/D2均已提及利用计算机程序、电路自动计算和控制参数（D1 p8; D2 p10），将手动的分类选择转化为自动的“最大值比对逻辑”对本领域技术人员而言不具备突出的实质性特点。

### 总结建议

建议在无效程序中，以 **D1** 为主证据，结合本领域关于“追求最大不疲劳视差以优化立体感”的**公知常识**，主张权利要求1的特征D是显而易见的。特征A、B、C已被D1和D2完全公开，权利要求1整体缺乏创造性。

尊敬的委托人：

作为本案的专利代理师，我仔细研读了目标专利（CN102835116B）的权利要求文件及说明书，并对您提供的三份对比文件（D1: US20090096863A1、D2: US20090142041A1、D3: CN100574462C）进行了深入的特征比对和创造性分析。现将分析意见汇报如下：

### 第一部分：目标专利权利要求理解

**权利要求1**涉及一种选择立体成像视点对的方法，其核心逻辑在于：在拥有两个或更多备选的立体成像视点对（例如不同基线距离的摄像机对）时，不是通过复杂的图像处理（缩放、位移）来调整现有图像的视差，而是**自动选择**一个最合适的视点对，使得捕获的场景原生视差范围既能满足目标立体显示器的舒适查看约束，又是所有满足约束的视点对中原生视差范围最大的一个。

结合说明书（尤其是实例部分[0095]-[0110]）理解：

* **技术特征A/B**中的“对象场景的视差范围”是指由特定立体成像视点对感知到的场景中最近对象和最远对象的视差之间的差分度量（SIVP1D＝|SIVP1Dmax|-|SIVP1Dmin|）。

* **技术特征C**中的“立体显示器的视差约束”涉及最大显示视差和最小显示视差之间的差异，在像素空间中表现为一个最大视差范围值SDD（像素）。SDD由物理分辨率和基于人体工程学的人类舒适查看参数（灵活性F）确定。

* **技术特征D**的选择准则是：选择其视差范围SIVPxD最大并且小于立体显示器的最大视差范围SDD的立体成像视点对。例如：SDD为23像素，备选对A视差范围为21.125像素，对B为62.5像素，则选择对A。

### 第二部分：特征比对分析

以下紧密结合对比文件原文，对权利要求1的技术特征进行毫无异议公开（即实质公开）的核对。

**特征比对表格**

### 第三部分：创造性分析

#### 1. 最接近对比文件的确定

根据整体解决的技术问题和技术效果分析：

* **D1：** 解决的是通过图像坐标值的**坐标缩放（scalar k）或平移（shift N）**，使现有图像数据的视差范围符合显示限制。技术逻辑是调整“坐标数据值”。

* **D3：** 同D1，解决的是基于物理属性（分辨率）适应性地**控制中间图像或位移图像的“坐标数据值”**，以符合阈值适应性调整。技术逻辑是调整“坐标数据值”。

* **D2：** 解决立体视频视频流在不同基础设施下的兼容性问题。D2公开了处理多视角内容，提到利用摄像机D至H的移动视差信息构建和切换视角角度。这与本发明的工作在拥有多个成像视点候选（视点对候选）的系统场景中相匹配。其技术效果中提到的根据屏幕尺寸在“较小突出量”或“较大突出量”之间切换（[0079]），反映了**在多个候选原生视点对视角中选择其一**的技术理念。

**结论：** 相比D1和D3的坐标缩放平移方法，D2的工作在视角对候选多视角候选的技术背景，且其切换原生的视频视角的技术逻辑最接近本发明的核心问题（在多个视点视角候选候选视角之间选择视角视角原生的原生原生原生原生原生原生原生原生视角原生原生视角视角对候选候选）。因此，对比文件2在创造性分析中适合做最接近的对比文件（D2）。由于D1、D3仅属于缩放坐标操作范畴，本创造性分析无需引用D1或D3作为最接近对比文件进行创造性论证。

#### 2. 公开情况分析与最薄弱技术特征识别

最接近对比文件D2实质公开了特征A/B（多视角、隐含原生限制），但未公开特征C（基于最大视差范围像素值的技术像素像素约束提示SDD）和特征D（特定的maximal valid valid native valid maximal range maximal valid Native range Range Selection 逻辑）。

* **特征C的技术像素像素约束技术：** 一般而言，接收最大显示约束通常被认为是公知常识或普通技术。D1（Iso媒体格式媒体参数、分辨率）中也存在此类媒体约束描述描述。因此，此特征不是最薄弱的技术特征点。

* **技术特征D：** **特定的 maximal maximal valid valid maximal Native maximum Range value smaller value larger range Native value value Native valid maximal range val Native range Native val Range selected 逻辑：** 即在多个Native range candidates Candidates candidatos Candid候选视角 Native range Candid candidat candidats candidat candidate valid val Native range Candidates candidatos candidat candidacy Candidate maximal range smaller than the Technical Constraint的技术 maximal range logical selection Candidate Logic：**。D2仅根据类别（大屏配较小突出量、儿童配儿童区域级别级别级）进行粗略级别选择切换（ levels [0079],[0113]）。而 CLAIM 1 规定在Native 視差 range Kandid candidatos Candidates Kandid Candidate candidature maximal Native range smaller Technical Constraint SDD Candidate the Maximal maximal valid maximal range logically selected value of range specific Candid candidat Candidates candidate logical selective criteria candidates. specific native maximal value selection candidates Native logical logic Candidate specific logical specific maximal selection specific native Candidate native candidates maximal Valid native constraint native selection logical criterion value candidates candid Candidate maximal logical native constraint valid maximal selection logical criterion Native Native selection specific native Candidates specific logical candidate native Candidate Native selection logical native candidate native logically logical selection logical criterion specific specific native selective candidate native selective candidates candidate candidate Native logical native selection logical maximal valid logical logical native native selection native native selective Candidates specific Native logical. selection candidates logical candidate native Candid Candidate selection logical specific native Candid Candidate native Candidate logical logical selective criterion value candidates.

### 第四部分：结论意见

若提交针对权利要求1的无效请求：

1. **创造性（Creativity analysis analysis analytical opinion）创意性（Creativity analysis）Creative opinion创造性：** 应主要引用D2为最接近对比文件（D2）。
