Purpose

Applications
Checking the presence or absence of packed parts, inspecting the working
condition of LEDs or fluorescent character display tubes, and sorting household
electric appliances.
[Inspection at 6 points]
The presence or absence of target objects is examined.
- A simple black or white evaluation is made in the specified pixel area of binary
images.
- The light level in the specified pixel area is averaged, and a decision is made
whether or not it is within the specified lightness range in gray scale images.
Number of points (max.)
: 128 points at average light levels
256 points in binary images
Point size: 2 m x 2n pixels
(m, n = 1 to 16)

Pur-
pose
Measure the distance and angle of two points using the center detection function in a gray
scale search and the edge detection function, as well as center of gravity detection by
functions.
- This function can measure the following distances and angles: distance between two points,
X coordinate distance, Y coordinate distance, the angle between three points, the horizontal
angle of two points, and the vertical angle of two points.
- The following points and lines can be set: center point, circle center point, gravity center,
point where two straight lines cross, line passing through two points.
[Measuring IC packages]
Register criterion image a and b by matching edges of the IC package.
- Measurement procedures
1 Find the center points of criterion images a and b using a 2-point gray scale search.
2 Determine the distance between the two center points.
