成像引擎14的透镜引导组件314最好能够设定为制造时所设定的两个不同的预定聚焦位置之一。 Lens imaging engine 14 of the guide assembly 314 is preferably capable of setting one of two different predetermined focus position is set during manufacture. 一个称为近聚焦的聚焦位置使成像引擎14能聚焦到大约五英寸(12.7cm)远的物体上。 Called a focus position near the focus of the imaging engine 14 can be focused to approximately five inches (12.7 cm) on a distant object. 第二个聚焦位置称为远聚焦,允许成像引擎14聚焦到大约九英寸(22.9cm)远的物体上。 The second focus position called far focus, focus allows the imaging engine 14 to about nine inches on a distant object (22.9cm). 这两个聚焦位置的超集提供给成像引擎14达到跨越各条形码密度范围的卓越工作范围,并且当设定到远聚焦位置时还提供改进的远景照片拍摄能力。 Superset of these two focus position to the imaging engine 14 to achieve superior operating range across each of the density range of the bar code, and when set to a shooting ability Shihai far focus position to provide improved vision pictures. 聚焦控制单元319由FOCUS_CTRL1和FOCUS_CTRL2信号来控制,该信号用于控制用来放置透镜组件302的马达318的运行。 Focus control unit 319 is controlled by FOCUS_CTRL1 FOCUS_CTRL2 and a signal for controlling the lens assembly 302 is used to place the operation of the motor 318. 放置透镜组件302的控制如表1所示。 Controlling the lens assembly 302 is placed as shown in Table 1.

表1-聚焦控制定义通常在条形码解码扫描期间,马达318将以反复模式运行,使得聚焦随每个所采集的帧在近焦和远焦之间变化。 Table 1 is defined generally focus control during decoding bar code scanning, the motor 318 will repeat mode, so that the focusing variation between the far focus and the near focus with each frame acquired. 在某些情形中,比如照片拍摄和具体的条形码读取应用,可能需要强加多个帧捕捉上的聚焦位置之一。 In some cases, such as photographs and a specific bar code reading application, you may need to impose more than one of the focus position on the frame capture. 一旦被命令进行操作,马达318将操作透镜调节机制216,用于沿透镜引导组件314将至少一个透镜312移动到指定位置,并且停留在那里20毫秒。 Once the command is operated, the operation of the motor 318 of the lens adjustment mechanism 216 for guiding the lens assembly 314 along at least one lens 312 is moved to the designated position, and stays there 20 milliseconds. 这表示最大曝光时间大约是帧时间减去20毫秒的停留时间,导致最大曝光设置为12毫秒。 This represents the maximum exposure time is about frame time minus the residence time of 20 milliseconds, resulting in maximum exposure is set to 12 milliseconds. 当以反复模式操作时,为保证适合的并且稳定的图像捕捉,软件应该设定曝光时间不大于12毫秒。 When operating in the repetitive mode, in order to ensure a suitable and stable image capture, the software should set the exposure time is less than 12 milliseconds. 如果强迫聚焦位置为较近或较远,则只要给马达20毫秒使其从强迫聚焦位置的时间停留到第一个图像曝光开始的时间,可使曝光时间像帧时间那样大。 If the focus position is forced to close or very far, as long as 20 milliseconds to the motor so as to force the residence time from the time the focus position of a first image exposure is started, the exposure time can as large as the frame time.

当启用反复模式时,在某些情形中可能需要知道所捕获的图像的聚焦位置。 When the repeat mode is enabled, in some cases you may need to know the focal position of the captured image. 假如在这样的例子中,当正在读取图像时,没有直接来自成像引擎14的对透镜组件302所处的聚焦位置的反馈。 In such an example, if, when the image is being read, there is no direct feedback from the imaging engine 302 is located on the focus position of the lens assembly 14. 知道聚焦位置的唯一方法是将成像引擎14初始化到一特定聚焦位置,并且然后在逐帧基础上跟踪当前聚焦位置。 The only way to know the focal position of the imaging engine 14 is initialized to a particular focus position, and then the track of the current position of the focus on a frame. 实现此任务的一个方法是通过使用FOCUS_CTRL1和FOCUS_CTRL2来使聚焦位置强制为一特定聚焦位置,然后将聚焦控制变为反复模式,并且命令平台20来启用EXSFT信号(比如,在平台中设定RUN比特(假设已经启用ACQ比特))。 One way to achieve this task by using FOCUS_CTRL1 to the focus position and FOCUS_CTRL2 forced to a particular focus position, and the focus control mode is repeatedly changed, and the platform 20 to enable EXSFT command signal (for example, setting the RUN bit platform (assuming that you have enabled ACQ bit)). 在EXSFT的每个上升沿,照相机聚焦会切换,从而会在与初始化位置相反的聚焦位置上捕获第一帧。 EXSFT each rising edge, the camera will focus switched so captures a first frame in the opposite position of the focus position on initialization. 下一个帧会在初始化位置处等等。 At the next frame will initialize the position and the like. 当这些帧中的每一个被捕获时,由平台20产生帧的中断末端,并且可用其聚焦位置标记该帧,同时当前聚焦位置切换到下一个位置,准备捕获下一个帧。 When each of these frames is captured, the platform 20 is generated by the interruption terminals, and the focal position marker which can be used in the frame, while the current focus position to the next position, ready to capture the next frame. 当使用功率模式AE中任一种时,最好设定初始聚焦位置以保证第一帧总是始于预定的聚焦位置。 When using any one of the power mode AE ​​is preferably set to ensure that the initial focus position of the first frame always begins a predetermined focus position.

以功率模式D操作平台20可用在例如扫描期间之中,此时已经获取两个帧并且正在处理它们,且系统继续让照相机运行但不采集,从而如果需要它可以积极地捕捉更多的帧,在该功率模式D中,运行是为成像引擎14来检测图像而启用的,但没有启用图像的采集(在平台20中,启用RUN比特(运行)并禁用ACQ比特(采集))。 A power operation mode D being used, for example the platform 20 during the scan, this time has been acquired and the two frames are being processed, and the system continues to run but does not allow the camera to capture, so that if necessary it can be positively capture more frames, in this power mode D, the operation for detecting an image forming engine 14 is enabled, but there is no image acquisition is enabled (in the platform 20, the rUN bit is enabled (running) and disable bits ACQ (acquisition)). 在这种情形中,处理器不会产生帧的中断末端,因为它并不作采集。 In this case, the processor will not generate an interrupt end of the frame, because it does not make the acquisition. 在这种情况下,跟踪聚焦位置状态变得更加困难。 In this case, tracking the focused position becomes more difficult. 建议如果使用功率模式D,马达应该强制为初始化的聚焦位置,直到启用采集(ACQ比特)。 If D is recommended power mode, the motor is forced to be initialized focus position until acquisition is enabled (bits ACQ). 这将保证聚焦控制被重新初始化到已知的起始位置,并且再次使用帧的中断末端来跟踪聚焦位置状态。 This will ensure that the focus control is re-initialized to a known starting position and the end of the frame used again interrupts to track the focused position. 根据设计要求,提供了在通电后会被写入成像引擎14(例如,LC99704)的DSP306的缺省照相机寄存器设置。 Depending on design requirements, it provides imaging engine is written after the power 14 (e.g., LC99704) of the camera DSP306 default register settings.

成像引擎14最好包括数字和模拟增益控制,该增益控制能够在I2C接口上手动地改变。 The imaging engine 14 preferably includes a digital and an analog gain control, the gain control can be changed manually in the I2C interface. 条形码读取应用通常并不利用数字增益控制,因为它一般并不提供真正的信号放大值。 Bar code reading applications typically do not utilize digital gain control, as it generally does not provide a true signal amplified value. 模拟增益是通过LC99704 DSP的寄存器157d来控制的。 Analog gain is controlled by the register 157d LC99704 DSP. 图7显示了根据写入寄存器157d的数字值获得的模拟增益。 Figure 7 shows simulated gain obtained according to the digital value written to the register 157d. 该模拟增益在随后读出的帧上生效。 The analog gain effect on the subsequent frame is read out.

平台20的采集接口最好是高度可编程的。 Preferably acquisition interface platform 20 is highly programmable. 需要被配置为保证照相机适当运行的关键项是:MCKI的设置,要与DSP306(在所提供的例子中,为来自平台20的11.981MHz)相适合;EXSFT的极性,在电源被施加到成像引擎14之后或在退出成像引擎的待机电源模式B之后,要与成像引擎14的启动顺序相匹配;当禁用采集/运行时EXHT和EXSFT的空闲状态;每行的像素数和每帧的行数与CCD相适合;以及直接存储器存取(DMA)目的地和重载地址寄存器。 Needs to be configured to ensure proper operation of the camera key terms are: MCKI provided to the DSP306 (in the example provided, from the platform to the 11.981MHz 20) suitable phase; EXSFT polarity of the power supply is applied to the imaged or after exiting the imaging engine standby power mode B, to match the engine after 14 and boot sequence imaging engine 14; and when disabled acquisition / runtime EXHT and EXSFT idle state; the number of pixels per line and lines per frame and suitable phase CCD; and a direct memory access (DMA) and a destination address register reload.

然后,处理系统确定成像光学装置相对于固定参考点移动到特定或大约的位置所需的距离数量。 Then, the processing system determines the imaging optical means with respect to a fixed reference point to the distance needed for a particular number or approximate location. 为执行这种计算,处理系统考虑了成像光学装置914的参考点相对于固定参考点的上一个存储位置。 To perform this calculation, the processing system takes into account the reference point of the imaging optical device 914 relative to a fixed reference point storage location. 当不考虑偶尔通过手动或自动地设置处于相对于固定参考点而言已知位置处的成像光学装置的当前位置来校准成像引擎的需要时,成像光学装置914的参考点的上一个存储位置就等于成像光学装置914的参考点相对于固定参考点的当前位置。 When not considering occasionally by manually or automatically set in the current position with respect to a fixed reference point at a known position of the imaging optical apparatus required to calibrate an imaging engine, a storage location reference point 914 on the imaging optical apparatus It is equal to the reference point of the optical imaging device 914 relative to the current position of the fixed reference point.
