    • In a photographic and data transmission system utilizing a wireless communication system, a camera used with the wireless system includes film or electronic sensor for capturing an image, a receiver for receiving a wireless signal from the wireless communication system, a decoder for decoding the wireless signal obtained by the receiver and magnetic layer on film or electronic storage device for storing the decoded wireless signal and the image. A trigger signal from the camera can be used to initiate transmission of the wireless signal from the wireless communication system. Moreover, the wireless signal preferably contains an internet address for accessing further information about an item being photographed. Such a camera is of particular use in a tradeshow for conveying information between a wireless communication system in a display booth and a camera brought to the booth by a tradeshow visitor.

    • A photographic and data communication system includes a camera used with a magnetic communication system in which information is stored on a magnetic medium external to the camera. The camera includes means for capturing an image, a magnetic read section for reading a magnetic signal from the magnetic medium, and a recording section for storing the magnetic signal in association with the image. More specifically, the camera is capable of receiving digital data through a magnetic recording head and saving received data along with the captured image. In case of a digital camera this extra information is stored in solid state memory on the camera. In case of a camera utilizing a film with magnetic tracks or regions, the received data is stored on the magnetic portion of the film. In case of a camera using regular film, the received information is stored on the camera in solid state memory to be downloaded later on. The invention is described in a tradeshow environment, although its use is not limited to such settings.
    • 照相和数据通信系统包括与磁通信系统一起使用的相机,其中信息被存储在相机外部的磁介质上。 相机包括用于捕获图像的装置,用于从磁介质读取磁信号的磁读取部分,以及用于与该图像相关联地存储磁信号的记录部分。 更具体地,相机能够通过磁记录头接收数字数据,并且与所捕获的图像一起保存接收的数据。 在数码相机的情况下,这个额外的信息存储在相机的固态存储器中。 在使用具有磁道或区域的胶片的照相机的情况下,所接收的数据被存储在胶片的磁性部分上。 在使用常规电影的相机的情况下,接收的信息被存储在固态存储器中,以便稍后下载。 本发明在商业展示环境中描述,尽管其用途不限于这种设置。

    • A camera includes an image receiver for capturing an image of an object, an optical section for directing image light from the object to the image receiver, and a viewfinder for viewing the object prior to capture together with a tile pattern for specifying active "hot spot" areas in the viewed image. The tile pattern in the viewfinder is composed of a plurality of individual tile areas that are visible through the viewfinder together with the image of the object. The camera further includes means for designating one or more individual tile areas as active areas of the image, and means for recording a location of the active areas in a memory location accessible to apparatus external to the camera. The camera is part of a system in which the apparatus external to the camera is a computer. A program in the computer is responsive to the recorded locations for enabling one or more specific actions to be assigned to the active areas of the recorded image when the image is accessed by the computer.
    • 相机包括用于捕获对象的图像的图像接收器,用于将图像光从对象引导到图像接收器的光学部分,以及用于在捕捉之前观察对象的取景器,以及用于指定活动的“热点 “所查看的图像中的区域。 取景器中的瓦片图案由通过取景器可见的多个单独的瓦片区域以及物体的图像组成。 照相机还包括用于将一个或多个单独的瓦片区域指定为图像的有效区域的装置,以及用于将有源区域的位置记录在相机外部的设备可访问的存储器位置中的装置。 相机是其中相机外部的设备是计算机的系统的一部分。 计算机中的程序响应于所记录的位置,以便当计算机访问图像时,能够将一个或多个特定动作分配给记录图像的活动区域。

    • A public key encryption system for authenticating an image includes a digital camera having embedded therein a private key unique to the digital camera. A known public key uniquely based upon the private key is used to decrypt digital data encrypted with the private key to establish authenticity of the image. The encryption system further comprises means for generating one or more patterns each composed of at least one individual area that is visible together with the image of the object, means for designating at least one individual area as an active area of the image suitable for authentication and for generating location data identifying the active area, and means for calculating image hash from image data of the active area of the image using a predetermined hash algorithm. The image hash is then encrypted with the embedded private key, thereby producing a digital signature uniquely associated with the active area of the image, and the image data, the digital signature, and the location data of said active area are stored in a digital record. By confining encryption to this selected region of interest, power requirements for subsequent hashing and encryption are reduced, which is an advantage for portable devices such as a digital camera.
    • 用于认证图像的公开密钥加密系统包括其中嵌入了数字照相机独有的专用密钥的数字照相机。 使用基于私钥的公知密钥来解密用私钥加密的数字数据,以建立图像的真实性。 加密系统还包括用于产生一个或多个图案的装置,每个图案由与物体的图像一起可见的至少一个独立区域组成,用于将至少一个单独区域指定为适合于认证的图像的活动区域, 用于生成识别活动区域的位置数据,以及用于使用预定的散列算法从图像的活动区域的图像数据计算图像散列的装置。 然后利用嵌入的私钥对图像散列进行加密,从而产生与图像的有效区域唯一相关联的数字签名,并且将图像数据,数字签名和所述活动区域的位置数据存储在数字记录 。 通过将加密限制在所选择的感兴趣区域,减少后续散列和加密的功率要求,这对于诸如数码相机的便携式设备是有利的。
