摘要： An image region of an image data memory is dissected into a plurality of search sections. Brightness change points in each of the search sections are counted based on image data of each search section. A candidate region having a likelihood of involving an information code is detected based on the count value of the brightness change points. And, the candidate region is identified as the existing area of the information code.

摘要： An image of a region is taken which includes a two-dimensional code. A two-dimensional code area is determined in the image. The two-dimensional code area corresponds to the two-dimensional code. Inspection lines are set which connect opposite sides in two pairs among four sides indicating boundaries of the two-dimensional code area in cases where the two-dimensional code is of a cell matrix type. Inspection lines are set which connect opposite sides in one pair among four sides indicating boundaries of the two-dimensional code area in cases where the two-dimensional code is of a bar-code stack type. Information is read from the two-dimensional code area on the basis of the inspection lines. Division points are set on the opposite sides in response to a ratio in length between sides adjacent to the opposite sides and a number of arrangements of cells in the two-dimensional code in cases where the two-dimensional code is of the cell matrix type. Division points are set on the opposite sides in response to a ratio in length between sides adjacent to the opposite sides and a number of stacked bar codes in the two-dimensional code in cases where the two-dimensional code is of the bar-code stack type. The inspection lines are set which connect corresponding ones of the division points.

摘要： An optical information reader which can promptly eliminate mirror reflection regions with high accuracy without the need for a plurality of expensive CCDS. When it is discriminated that mirror reflection regions exist in an image of a two-dimensional code obtained by a CCD under illumination condition 1, the condition is changed to illumination condition 2 and an image is obtained. If there is a mirror reflection region also in the new image, the previously obtained image and the new image are synthesized by calculating the OR. When no mirror reflection regions exist in the synthesized image, a decoding is executed. Since it is sufficient to use only one CCD in the optical information reader, system cost is minimized. As images are obtained by the same CCD, even if images are synthesized, a positional deviation does not occur, the mirror reflection regions can be promptly eliminated with high accuracy, and an obtained image is accordingly very accurate.
摘要翻译：一种光学信息读取器，其可以以高精度快速消除镜面反射区域，而不需要多个昂贵的CCDS。当在照明条件1下鉴别出由CCD获得的二维码的图像中存在镜面反射区域时，将条件改变为照明条件2并获得图像。如果在新图像中也存在镜面反射区域，则通过计算OR来合成先前获得的图像和新图像。当合成图像中不存在镜面反射区域时，执行解码。由于在光学信息读取器中仅使用一个CCD就足够了，所以系统成本最小化。由于通过相同的CCD获得图像，即使合成图像，也不会发生位置偏差，因此可以高精度地迅速消除镜面反射区域，因此获得的图像非常准确。

摘要： A method of reading a bar code having guard bars at both sides thereof without fail even if the bar code image is highly distorted. An image region taken in by a CCD camera is scanned in horizontal and/or vertical directions to find out a first guard bar in the bar code. Then, a first scanning line for reading the bar code is set in a direction perpendicular to the first guard bar. The bar code is scanned along the first scanning line. If the first scanning line goes out of the bar code region, the first scanning line is traced back to a bar which is last read. Another scanning line starting from the last read bar and extending perpendicularly thereto is set to read the rest of the bar code. This process is repeated until the second guard bar is detected and a whole bar code is completely read. The first scanning line may be set, so that it only reads a predetermined number of bars and the rest of the bar code is read by new scanning lines starting from the last read bar. Alternatively, the bar code region is searched by preliminarily scanning the image region divided into plural rectangular sections. The bar code region is determined based on the number of brightness changes in each divided section. The first guard bar in the bar code can be easily found in this manner.
摘要翻译：即使条形码图像高度失真，也不会失败地读取其两侧具有保护条的条形码的方法。通过CCD摄像机拍摄的图像区域在水平和/或垂直方向上扫描，以便在条形码中找到第一保护条。然后，在与第一保护条垂直的方向上设置用于读取条形码的第一扫描线。沿着第一条扫描线扫描条形码。如果第一条扫描线超出条形码区域，则第一条扫描线将被追溯到最后读取的条形。从最后一个读取条开始并垂直延伸的另一个扫描线被设置为读取条形码的其余部分。重复该过程，直到检测到第二保护条，并且完全读取整个条形码。可以设置第一扫描线，使得其仅读取预定数量的条，并且从最后读取条开始，通过新的扫描线读取其余条形码。或者，通过预先扫描分割成多个矩形部分的图像区域来搜索条形码区域。根据每个划分的部分中的亮度变化的数量来确定条形码区域。条形码中的第一个保护条可以轻松地以这种方式找到。

摘要： An information reading apparatus such as a handheld personal device comprises a memory having a plurality of cells arranged in a two-dimensional array of rows and columns. Each cell stores a symbol image to be displayed on a screen. When a matrix array of cells is displayed, a cursor key is used to select one of the displayed cells as a candidate by moving a selection point by one cell at a time in response to a user's operation and is used to enter a user's decision command when a desired candidate is displayed at the center of the screen. A matrix array of cells including the selected cell and its neighbor cells are read from the memory and displayed so that the selected cell is positioned at the center of the screen. The processes of reading and displaying are repeated in response to a user's operation until the user's decision command is entered.
