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： 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.
