摘要： An optical code scanner is presented that includes image capture technology to read optical codes. The optical code scanner captures an image of an optical code and then generates multiple reduced resolution versions of the image. Multiple techniques are applied to the different images to identify a region of interest, enhance the contrast of the image, perform a non-linear local geometrical distortion correction and minimize the spatial resolution required to read the optical code. The techniques reduce the raw processing power and time required to identify and read an optical code.

摘要： A liquid crystal display (LCDS) which has higher contrast characters than previously available LCDs, particularly LCDs used in electronic price labels. The LCD includes a number of characters containing segments including four vertical segments and three horizontal segments arranged in a figure-8 shape. The four vertical segments have a width determined by a segment width to character width ratio of about 0.208-0.283 and the three horizontal segments have a width determined by a segment height to character height ratio of about 0.100-0.150. The LCD also includes two diagonal segments defined by two parallel lines to enhance visibility of characters such as the letter “N”.

摘要： Methods and apparatus are provided for low resolution item identification. An image of an unknown item is captured and quantized to greatly lower the resolution of the image. The quantized image data of the unknown item is compared to a plurality of the quantized image data for known items. The comparison includes using a signal-to-noise ratio calculated using the quantized image data for both the unknown and known items. A match is found when the calculated signal-to-noise ratio is above a predetermined threshold value.

摘要： Methods and apparatus are provided for fast item identification. A plurality of sensors capture data for an unknown item that is moved past the sensors. The data is processed to produce a plurality of physical attributes related to the unknown item. The physical attributes are used to search a database of physical attributes for a large number of known items where the unknown item is one of the known items. A small set of known items are selected where the physical attributes of the known items match the physical attributes of the unknown item. Further processing of the selected set of known items identifies the unknown item as one of the set of known items.
