Page 51: Color Pattern Matching
4.3 Color Pattern Matching 4.3.1 Overview of Color Pattern Matching In the image from which a registed color was extracted, the LightPixAE20 detects the registered base image (template) in the inspection area (, which is called “Searching“). The unit judges whether the detected image is positioned within the allowable range (the base position +/- set range).
Page 52 Conditions under which inspection image position is judged as OK If the detected image is positioned within the position of the saved template +/- allowable range (settable in JUDGEMENT CRITERIA SETTING mode), the LightPixAE20 judges as OK. Settings of teaching and judgement criteria X and Y are judged as OK X and Y,or Y or Y are judged as NG.
Page 53 About inspection steps The LightPIxAE20 separately searches an image similar to the template within the inspection area at second and third steps. The number of steps varies depending on the inspection speed (settable in CONFIGURATION mode) When the inspection speed is set to “High” or “Middle”, inspection is performed at three steps, and when it is set to “Low”, it is performed at two steps.
Page 54 Detailed conditions: Number of detection candidates Number of detection candidates At the first and second steps, if you set the number of detection candidates when there are multiple images having more than the specified degree of similarity, you can detect the images of the specified number. The detected multiple images are called the “number of detection candidates”.

Even if you selected X-directional measurement direction in CONFIGURATION mode, Y-directional base length and the allowable range do not affect the inspection results. Similarly, even if you selected Y-directional measurement direction in CONFIGURATION mode, X-directional base length and the allowable range do not affect the inspection results. 4.6.7 Measurement Execution The ways of mesurement execution Internal trigger: ON...
Page 101 Checking measurement data When carrying out measurement in RUN mode, you can check the minimum and maximum of the detected length in the X and Y directions. When setting the direction of the inspection object in CONFITURATION mode to X, you can check the default or previous settings by selecting Y, but you should not refer to the settings.

5.2 Input/Output Timing 5.2.1 Performing a Reading Operation (Internal Trigger: OFF) When you perform inspection by inputting the TRIGGER signal from external devices, follow the timing chart shown below. If you switch product types before executing an inspection, input the signals following the timing chart below.
Page 110: Switching Product Types
5.2.2 Switching Product Types What is product type switch? Product type switch is to call a product type, for which you want to execute an inspection or a teaching, from product types of 1 to 7. To switch product types: Specify a product type number you want to change using TYPE 1-3 signals (see the table shown below).
Page 111: Teaching
5.2.4 Teaching The LightPixAE20 can execute a teaching using the signals from the external devices based on the currently captured image, but exposure time and binary level may be changed after teaching execution. Therefore, execute a teaching only if there is no problem having these values changed. Timing chart: Teaching for OK product only 1.
Page 112 Timing chart: Teaching for OK and NG products If the TEACH function is set to OKNG in CONFIGURATION mode, execute a teaching following the instructions below: 1. Confirm that the READY signal is ON and inptut the TEACH signal. 2. Input a product type, for which you want to peform a teaching, to the ports of TYPE 1-3 in more than two milliseconds (T1).
