The task of focusing objects might be difficult to perform with high resolution cameras. The operator of the camera might be adjusting the lens of the camera to obtain the best focus possible based on what his/her eyes can see. This is more complicated to do when the scene has low contrast or small objects. So, how can an operator make sure that he/she is achieving the best focus of a scene?
LEADER introduced a new feature on its LV5490 called FOCUS ASSIST (patent-pending). This optional feature implements an algorithm that shows a colored-shade area of the object when focus is achieved. The larger the area is covered by the shade the more focused it is. So the operator can be adjusting the camera lens and see on the monitor or viewfinder when the object is best focused.
