2 New lgorithm Developed for Capture & Process that Enables Stable Our original corrective capture and process techniques provide the best-in-its-class reading capability even for difficult-to-read codes. newly developed algorithm automatically selects the optimal settings from as many as 25 correction patterns. Capture utomatically selects optimal reading conditions such as brightness and filters to clarify codes as much as possible before reading. Process newly developed processing method ensures accurate black/white reproduction even for irregular codes. 2

3 est in its class Capability newly developed algorithm provides best-inits-class reading capability. Difficult codes can also be scanned stably, including those directly marked on uneven workpieces. Easy Tuning The SR-75 is just as easy to operate as any other SR Series so that anyone can enjoy its excellent reading performance. In addition, the optimal settings can be obtained in three simple steps through automatic tuning. First in its class Predictive Maintenance Image quality can be judged based on industrial standards. It is also possible to output judgement results as signals, so that you can understand clearly when maintenance is required in the printing process. rate Grade 1% rate 1% Grade D 3

4 New lgorithm Provides est-in-its-class Capability Captures Codes Clearly Corrects codes that are difficult to read due to print density or other conditions so that they can be captured clearly. The optimal capture settings are automatically selected according to code conditions. Capture rightness Correction Contrast Threshold Correction Image Reduction & Correction Corrects the brightness by automatically selecting the optimal settings for capture from 129 levels of brightness. utomatically corrects black/white classification thresholds and optimises the contrast between code and background. Reduces the image size to one that is ideal for decoding the code that is captured in the field of view. Examples of codes to be highly affected Examples of codes to be highly affected lack resin PC rass Nylon resin Low contrast Ceramic Correction through Filters Geometric Correction utomatically selects the best filter and filtering intensity for the captured image to correct it. Corrects distortion, such as that found on cylinders.

5 Processes Captured Codes Thanks to condition-based processing, read errors are reduced even if codes on captured images are difficult to read. Local Concentration lack/white Classification lgorithm Conventionally, black/white thresholds are set for the entire code, which makes it difficult to detect unevenly printed codes. To solve this problem, we have developed a new algorithm, called local concentration black/white classification algorithm, to allow thresholds to be set for each part of a code. This algorithm enables highly accurate black/white classification even for DPM codes, on which uneven print density often occurs. 2D Code Search in Captured Images newly developed WHS (High Speed & High Stability) search programme can detect a 2D code in the field of view immediately so that high-speed, stable search is ensured even when the code position changes or there are several 2D codelike patterns in the field of view. Conventional Technique Local Concentration Technique inary processing enables immediate detection of 2D codes even if there is a codelike pattern in the field of view. 1 Threshold Determination Defective Code Positioning Programme inary Processing Our local concentration black/white classification algorithm divides a code into smaller pieces to perform binary processing using thresholds specified for each part. This enables accurate black/white classification without being affected by uneven print density. * The above illustration is only for reference and does not mean that a code is always divided into 16 parts. newly developed defective code positioning programme can identify four corners of a 2D code based on a similar code detection pattern, leading to a significant improvement in code detection performance.

7 Stable Operation with the Preventive Maintenance Function Image Quality Check by Code Reader The SR-75 Series is the first product in this class that is capable of judging the image quality of a scanned code. This enables you to identify image deterioration before an error occurs, thus ensuring stable operation. Matching Level Judging Function Enables safety factors of scanning to be compared fter a code is scanned successfully, it can be determined how easily the SR-75 Series has scanned it. This information can be used to check the safety factor of scanning or as a correlation index for the parameter bank during tuning. Two codes, which both have a reading rate of 1%, can still be distinguished by a safety factor rate Matching level 1% rate 1% 75 Matching level 43 The above shows that the left code has a higher safety factor than the right one. Image Verification Function Verification based on image quality standards Total grades can be judged based on output verification result data or preset thresholds and then output as signals. This function is designed for 2D codes (, ). Output data D-ERMT-55841: Total grade judgement Judgement can also be performed for each character Supported Standards ISO/IEC ISO/IEC TR (IM DPM-1-26) SE S9132 SEMI T1-71 The multi-i/o function outputs image verification results Various operating conditions can be assigned to two input terminals and three output terminals. Sample outputs of image verification results OUT1: Stable read output (STLE) OUT2: Unstable read output (UNSTLE) OUT3: Read error output (ERROR) ny thresholds can be set for STLE and UNSTLE. 7

9 Master/Slave Function for Using Multiple Readers Effectively This function reduces the programming load on the host computer drastically when multiple SR-75 readers are used. Two modes are available: multi-drop link mode and multi-head mode. (The SR-D1 Series can also be used in combination.) Multi-drop link mode HU Host In this mode, data read by multiple SR-75 Series readers (up to 32) working for different purposes are sent collectively by a single master to the host. This eliminates the need for the host to control communication among multiple readers, simplifying programmes in the system. Slave station Slave station Master station The master station sends data from slave stations to the host. PC PLC Multi-head mode This mode allows multiple SR-75 Series readers (up to 8) to be handled as a single device. s a result, the host does not need to consider control over multiple devices, leading to simpler programmes. Slave station HU The master station controls slave stations. Host PC Slave station Master station PLC Powerful on Fast-Moving Workpieces urst read function: cquires up to 8 consecutive images. The decoding process is performed after continuous imaging, allowing for higher speed code detection. High-speed image capture performance: The built-in ultra-high-intensity LED, bright enough even in a short exposure time, and high-speed digital signal processor (DSP) can capture moving objects effectively.
