    • A flame detector is provided. A circuit board is disposed in a housing. A first light source emits first light. A light guide member comprised of translucent material guides the first light from the first light source to a light emission portion of the light guide member. A first light receiving element detects second light having a predetermined wavelength unique to the flames. A second light source emits third light to a translucent cover which is disposed between an opening of the housing and the first light receiving element. A second light receiving element detects the third light passed through the translucent cover to test the translucency. The first light source, the second light source and the second light receiving element are mounted on the circuit board. The light emission portion is formed into a substantially annular shape which encloses the first light receiving element at a front side of the housing to limit a field of view of the first light receiving element to a predetermined range. And the light guide member has a light entrance portion and a light exit portion for the third light to form a light path from the second light source to the second light receiving element through the translucent cover and the light guide member.

    • Background images are removed and only desired payment information is extracted from a grayscale image of a check or similar financial instrument. A density distribution improvement process applied to grayscale raw image data 40 acquired by scanning a check corrects the density distribution of the raw image data 40 to separate the density range of the desired payment information from the density range of the background image. A threshold level 44 for clearly separating the payment information from the background image is then calculated from the characteristics of the density distribution of the grayscale improved image data 42 acquired by the density distribution improvement process. Histograms of the density distributions are used to determine the characteristics of the density distribution. The improved image data 42 is then converted to binary image data 46 using the threshold level 44.
    • 背景图像被去除,并且仅从支票或类似金融工具的灰度图像中提取期望的支付信息。 应用于通过扫描检查获取的灰度级原始图像数据40的浓度分布改进处理校正原始图像数据40的浓度分布,以从背景图像的浓度范围分离所需支付信息的浓度范围。 然后,根据通过密度分布改善处理获取的灰度级改善图像数据42的浓度分布的特性,计算用于将支付信息与背景图像清楚分离的阈值水平44。 密度分布的直方图用于确定密度分布的特征。 然后,使用阈值电平44将改进的图像数据42转换成二进制图像数据46。

    • Column misalignment between a magnetically-recognized character string and an optically-recognized character string is corrected to improve character recognition reliability. A character string is read magnetically and the result outputted. The same character string is also read optically and the result outputted. A magnetic data reading unit detects the magnetism of a character string printed in magnetic ink and outputs the detected magnetic data. A recognition result comparing unit then applies a column offset detection process to detect misalignment between the character columns in the magnetic and optical results, then applies a column offset correction process to correct any column offset and align corresponding character columns. The comparing unit then compares corresponding character columns in the magnetic data recognition result and image data recognition result. For each position comparison, the comparing unit outputs the common character if the magnetically-recognized and optically-recognized character at that position match, or a question mark if the magnetically-recognized and optically-recognized character at the position do not match or if one or both of the magnetically-recognized or optically-recognized character is missing.
    • 校正磁识别字符串与光学识别字符串之间的列未对准,以提高字符识别可靠性。 一个字符串被磁性读出,并输出结果。 同样的字符串也被光学读出并输出结果。 磁数据读取单元检测打印在磁墨中的字符串的磁性,并输出检测到的磁数据。 识别结果比较单元然后应用列偏移检测处理以检测磁和光结果中的字符列之间的未对准,然后应用列偏移校正处理来校正任何列偏移并对齐对应的字符列。 比较单元然后比较磁数据识别结果中的相应字符列和图像数据识别结果。 对于每个位置比较,如果在该位置处的磁识别和光学识别的字符匹配,则比较单元输出公共字符,或者如果位置上的磁识别和光学识别字符不匹配或如果一个 或者磁识别或光学识别的字符都丢失。

    • Column misalignment between a character string recognized by a MICR and a character string recognized by optical character recognition is corrected to improve character recognition reliability. A magnetic data reading unit detects the magnetism of a character string printed in magnetic ink and outputs the detected magnetic data. An image reading unit optically reads the same character string printed in magnetic ink and outputs the image data. A magnetic data recognition unit applies a character recognition process to the magnetic data output by the magnetic data reading unit and outputs magnetic data recognition result. An image data recognition unit applies character recognition to the image data output by the image reading unit and outputs image data recognition result. A recognition result comparing unit applies a column offset detection process to detect misalignment between the character columns in the magnetic data recognition result and image data recognition result, then applies a column offset correction process to correct the column offset and align corresponding character columns, and then compares corresponding character columns in the magnetic data recognition result and image data recognition result based on the character strings after correcting the column offset and outputs a final recognition result.
