Abstract: The present invention relates to a data storage system and specific command execution method thereof, which is applied to a memory storage system. When a memory manager receives an command from a host system, it can judge whether the command is a normal command or a specific command. If the command is the specific command, read a first logic sector address, an accessible data length and a second logic sector address in the specific command, and duplicate the first logic sector address pointing to the physical storage address of the stored data reading to a memory buffer; and move physical storage address pointing to that from the first logic sector address to the second logic sector address. It can achieve both data reading and data moving by one specific command.

Abstract: An automatic testing method applied to an automatic testing system for testing a barcode identification apparatus is described. In the method, a test host is utilized to generate a barcode pattern automatically, so as to display the barcode pattern through a barcode revealing apparatus. The barcode identification apparatus reads and resolves the barcode pattern to retrieve an identification result. The identification result is returned to the test host. The test host compares the barcode information carried by the barcode pattern and the identification result, and generates a test result. The test host repetitively generates the barcode pattern for a barcode identification apparatus carried the barcode pattern and the identification result, and then generates a test result. Through the test host repeatedly generates the barcode pattern and records the corresponding test result, manual operation is not required to obtain testing data for being analyzed.

Abstract: A barcode recognition method is provided for recognizing a barcode to derive effective barcode information thereof. The barcode includes a plurality of segments. In the method, every time the barcode is scanned and recognized, any segment, in which a barcode information fragment carried therein is able to be derived, is recorded as an effective segment. And then the effective segments are selected and combined to generate a plurality of segment combinations. The information carried by the segment combinations is respectively verified by the checksum thereof, so as to find out the segment combination, which is successfully verified by the checksum thereof, to be the effective combination. Every time the barcode is scanned and recognized, only part of the segments of the barcode has to be successfully recognized, and the effective segments derived are combined and verified, so as to quickly recognize the barcode.

Abstract: A method of improving multi-type barcode recognition efficiency using continuous sampling is applicable to a barcode recognition apparatus. According to the method, each barcode type is given with a corresponding weight value, and a total weight threshold is set in the barcode recognition apparatus. A barcode pattern is sampled with a limited number of times, and each sampled image sample is only compared with a part of the supported barcode types. When the comparison matches, a weight value is assigned to the matched barcode type, and the weight value is accumulated to acquire a total weight value of the matched barcode type. When comparison of all image samples is finished, the barcode type with the total weight value reaching the total weight threshold is the barcode type of the barcode pattern, and a recognition result of the barcode pattern is output according to the barcode type.

Abstract: A barcode recognition method is applicable to a data processing apparatus. According to the barcode recognition method, after the data processing apparatus is turned on, a control module loads and initializes a barcode recognition program from a data storage device, and then switches the barcode recognition program to background execution. The control module continuously monitors whether a trigger event occurs to the data processing apparatus. When the trigger event occurs, the control module switches the barcode recognition program to foreground execution. When the barcode recognition program is in foreground execution, an image capture module captures at least one image frame, for the control module to recognize. The control module derives barcode information, so as to obtain a recognition result. After the control module outputs the recognition result to other application programs by simulating keystrokes, the control module switches the barcode recognition program to background execution.

Abstract: An image processing method of locating and recognizing barcodes in an image frame is applicable to an image processing apparatus. The method is to define plural scan tracks on the sample image frame, and the image processing apparatus searches for the section(s) possibly having the barcode, along each scan track. If the section(s) possibly having the barcode found on two neighboring scan tracks by the image processing apparatus is located at an approximate horizontal axis position, the image processing apparatus determines that a quadrilateral area defined by the two sections possibly having the barcode is an area possibly having the barcode. Therefore, the image processing apparatus can quickly locate and recognize the barcode area in the image frame.

Abstract: A method for multi-type barcode recognition is provided for recognizing a current barcode, so as to determine a barcode type of the current barcode among supported barcode types and the corresponding barcode information. In the method, a record table is loaded in advance for recording the matching frequency that each supported barcode type matches the barcode type of recognized barcodes. According to the matching frequency these supported barcode types are sorted in a recognizing sequence to be utilized to recognize the current barcode according to the recognizing sequence. Every time a current barcode is to be recognized, the supported barcode type utilized to recognize the current barcode is picked up according to the recognizing sequence, so as to determine the barcode type of the current barcode. The supported barcode type that most frequently matches the recognized barcode will be picked up at first, therefore, the barcode recognition efficiency is improved.
