背景技术
借助照相技术的图像的产生已经被众所周知相当的时间周期了。此外，最近，数字照相机以变得日益流行，其中图像通过数字照相机设备被捕获并被存储，用于以后打印。
在申请人的申请USSN 09/113,060，09/113,070和USSN 09/113,222中，提出了一种照相机系统，其包括完整的打印机设备，用于打印出被感测的图像。
在使用这种设备和其它图像捕获设备时，能够在拍摄图片时适当地处理音频和其它环境信息是理想的。
在申请人的申请USSN09/113,107中公开了一种这样的设备，其中通过在白背景上使用黑墨，音频数据被记录在卡或照片的后面。读取器可在卡或照片穿过扫描器装置时通过声频发生器装置读取和再现该信号。
在US 5,896,403(Nagasaki等)中公开了一种打印系统，其以点代码把图像和音频信息打印在打印媒质上，例如纸张，所述点代码可以由笔设备读取。尽管数据的扫描是不规则或随机的，由于点代码的组织，信息可以被解码。在Nagasaki等的系统中，数据扫描是低的。在如公开于USSN09/113,107中的申请人的打印和扫描系统中，处理是页宽处理，而不是如Nagasaki等的逐行处理。
发明内容
本发明涉及一种照相机系统，其除了能够在观察“照片”时回放音频信息之外，还能够在获取所感测的图像时记录音频，该音频和“照片”被记录在打印媒质的相同表面上。
根据本发明的第一个方面，提供一种用于播放预先记录的音频的系统，其以容错方式编码为不可见墨点阵列，被打印在照片上与照片基本相同的区域中，该系统包括：红外扫描器装置，用于扫描所述预先记录音频的打印的不可见墨点；处理器装置，其被互连到所述红外扫描器装置，用于解码所述扫描的音频编码以产生对应的音频信号；以及音频发射器装置，其被互连到所述处理器装置，用于依需要发射或播放所述对应的音频信号。
不可见墨可以是一种在可见光谱中具有可忽略的吸收的红外(IR)吸收墨。
编码可以包括对预先记录的音频的Reed-Solomon编码，并且包括使用页宽喷墨打印头打印在照片上的IR(红外)墨点阵列。所述点的阵列可以例如使用棋盘图案(checkerboard pattern)来高频调制，以有助于扫描。
所述系统可以包括具有槽的棒状臂，通过该槽所述照片被插入。
根据本发明的又一个方面，提供一种解码预先记录的音频信号的方法，所述音频信号是以容错编码形式在照片的表面上打印为不可见墨点阵列，其与打印在所述照片的所述表面上的图像一致，所述方法包含步骤：
(a)以红外对在所述照片上的打印的编码形式的所述预先记录的音频进行扫描；
(b)解码所述编码的音频信号；以及
(c)在音频输出设备上播放所述音频信号。
附图说明
不管可落在本发明的内容中的任何其它形式，仅为了举例，在此本发明的优选形式将参考附图来描述，其中：
图1示意性地示出了根据本发明的优选实施例构建的照相机系统；
图2示意性地示出了用于在输出媒质上打印的打印机机制；
图3示出了照片上的输出数据的格式；
图4示出输出媒质的放大部分；
图5示出了用于从照片读取数据的读取器设备；以及
图6示出了优选实施例的装置的使用。
具体实施方式
优选地，优选实施例通过对手持照相机设备的适当编程实现，如在USSN09/113,060和USSN 09/113,070中描述的。
上面提及的专利说明书公开了一种照相机系统，此后公知为″Artcam″型照相机，其中所感测的图像可以由Artcam便携式照相机单元直接打印出来。而且，上面提及的说明书公开了用于对由照相机传感设备捕获的图像进行各种操作而导致在任何输出图像上产生各种效果的装置和方法。该操作被公开为在本质上是具有高灵活性，并且可以通过插入在其上编码的用于图像的操作的不同指令的Artcam卡来实现，这种卡被公知为Artcards。Artcam还具有通过Artcam中央处理器单元(ACP)实现的重要的板上处理能力，其被互连到存储器设备，以便输入数据和图像的存储。
在优选实施例中，Artcam设备进行了适当修改，以便为其配备有麦克风设备以及相关的记录技术。当拍摄图像时，提供机会以记录周围的声音环境或者与该图像有关的消息。然后，被记录的音频以编码格式被打印在照片上，该编码优选地是高能复原的形式的。所记录的音频提供了与照片有关的永久的音频记录。之后，回放装置被提供以用于扫描该编码的音频信息并解码该信息。
现在参考图1，示意性地示出了优选实施例1，其包括如上面提及的专利说明书中描述的设置，其中，通过CCD传感器3，图像2被感测，并被转发到ArtCam中央处理器4中，中央处理器4包括重要的计算资源，如上面提及的专利说明书中所述。Artcam中央处理器4可以把图像存储在存储器5中，存储器5优选地包括高速RAMBUS(商标)接口的存储器。Artcam中央处理器4还负责控制打印机设备6的工作，打印机设备6具有页宽喷墨打印头15(见图2)，用于打印出全色照片，例如7，从而在需要时提供即时图像。打印头15可以打印彩色图像，并且具有至少(4个)喷墨嘴，用于在1600dpi分辨率打印。这四种墨包括用于打印数据的红外墨，以及用于打印彩色图像的青、洋红和黄墨。这样的打印头，但是具有使用六(6)种墨来打印的能力，被公开在申请人的申请PCT/AU00/00743，PCT/AU00/00744，PCT/AU00/00745，PCT/AU00/00746，PCT/AU00/00747和PCT/AU00/00748，其使用整体结构。
在优选实施例中，照相机设置1还装备有声音芯片10，其在ACP处理器4的控制下通过RAMBUS总线11与存储器5接口。声音芯片10可以具有标准或者特定的形式，且可例如包括从声音麦克风13获得模拟输入12的DSP处理器。可替换地，随着增加的芯片复杂性(摩尔定律)，声音芯片10的功能可以被结合到ACP芯片中，其优选地包括集成在电路芯片中的前沿CMOS型。将很容易看出，落在本发明范围内的许多其它类型的设置可被提供。声音芯片10把模拟输入12转换为对应的数字形式，并将其转发以存储在存储器5。在拍摄照片时，记录过程可以通过按下照相机设备上一处在ACP处理器4的控制下的按钮(未示出)来启动，或者它可以基本上是自动的。所记录的数据被存储在存储器5中。
现在参考图2，照相机设置优选地包括打印机设备6，其包括打印头15。打印头15用于在打印媒质17上打印图像，且同时使用IR墨在打印输出媒质17的相同表面上打印音频(或其它)信息。在USSN09/112,741中描述了类似的装置，但用于在输出照片图像的背面打印信息，其内容经必要的修正在此引入以供参考。通过使用单个打印头，提供了比这里公开的更简单的装置。申请人已在以下公开了适于此目的红外墨：于2000年8月14日提交的澳大利亚临时专利申请PQ9412和PQ9376、以及于2000年8月18日提交的申请人的申请PQ9509、以及于2000年8月21日提交的PQ9571和PQ9561。
现在参考图3，示出了打印在照相媒质17上的输出的实例。媒质17包括照相图像18，信息20和数据22与该照相图像一起被打印。为了易于显示，没有示出图像18的细节。信息20可以包括地点、日期与时间数据，其中地点信息通过键盘输入或可替换地，通过使用所附的定位系统，如GPS等而被提供。信息20以一种可视的形式被呈现。数据22以编码的不可见(但是红外可见)的形式被提供，其开始与结尾由目标边界23标记。编码格式可以是许多的和各种的，但是优选地，编码以高容错的方式被提供，以便容许刮擦、尘垢、书写、磨损、旋转、褪色等等。一种形式的合适技术是在“Artcards”结构中利用的打印技术，如上面提及的专利说明书USSN09/113,060中所述、或如USSN09/112,070和USSN09/112,785中、或者与此同时提交的共同未决申请代理号PCT/AU01/01317(代理号：ART80)、PCT/AU01/01328(代理号：ART81)和PCT/AU01/01326(代理号：ART82)中中所公开的。编码格式在很大程度上依赖数据的Reed-Solomon编码的使用来提供高度的容错。数据25的部分以示意性的形式在图4中示出，且该数据包括由图2中的打印头15打印的IR点阵列，其另外由添加到数据上的高频“棋盘”图案21来调制，以帮助感测所编码的数据。在该特定实例中，数据22可包括声音数据以及图像信息20。在申请人的共同未决专利申请代理号PCT/AU01/01317(代理号ART80)、PCT/AU01/01328(代理号ART81)和PCT/AU01/01326(代理号ART82)中所讨论的公开的方法在具有用于以1600dpi的分辨率打印的数据的4”×6”(102mm×152mm)的尺寸的照片上提供了大概6MB的任意数据的存储。
当需要“回放”记录的音频时，该照片17被通过读取器设备26，其包括夹送滚轮，用于将照片17夹送滚动通过对红外敏感的线性CCD传感器设备27，照片17同时被互补特性的红外线源照射。传感器设备27可以合适的适配的传感器设备，如上面提及的专利说明书或者申请人的专利申请PCT/AU01/01324(代理号ART85)的说明书中所述的。在平台扫描器或传真机中找到合适的传感器。CCD设备的传感器被提供有透镜化和/或过滤设置，以便对照片的尺寸以及IR墨的光谱特性优化其灵敏度和覆盖范围。在400-700mm波长范围中具有最小响应和在700mm-1200mm波长范围中具有最大响应的墨被发现是合适的，如在于2000年8月14日提交的澳大利亚临时专利申请PQ9412和PQ9376，以及申请人的于2000年8月18日提交的专利申请PQ9509、和在2000年8月21日提交的专利申请PQ9571和PQ9561中所公开的。
现在参考图6，其以示意性的形式示出图5中的音频读取器设备26的工作。线性CCD IR传感器27被互连到第二Artcam中央处理器28上，其适合适配于读取和解码以红外墨存储在照片上的数据。所解码的音频信息被存储到存储器32中，以便通过声音处理芯片33在扬声器29上回放。声音处理芯片33可以在ACP解码器28的控制下工作，ACP解码器28又在各种用户输入控制33的控制下工作，其可以包括音量控制、倒回、播放、以及快进控制等等。重要的是，如果信息是以在上述专利说明书USSN 09/113,070和USSN 09/112,785或者申请者的同类专利申请PCT/AU01/01317(代理号ART80)、PCT/AU01/01328(代理号ART81)和PCT/AU01/01326(代理号ART82)中描述的Artcard或可替换的Artcard格式来打印的，则CCD线性IR传感器27和ACP解码器28可以实现读取处理。
从对优选实施例的上述描述中可以看到，提供了一种用于自动记录与输出图像有关的音频从而提供与照片有关的音频记录的系统。还公开了一种用于读取使用IR墨记录在照片上的音频输出的音频读取器系统。
本领域技术人员将理解，在不脱离广义描述的本发明的精神和范围的情况下，可对如特定实施例所示的本发明进行多种变化和/或修改。例如，利用更复杂的音频记录和回放技术，例如立体声和B格式技术。因此，本发明的实施例在所有方面都被认为是说明性的，而非限制性的。
