The Focus Assist Function Software for LV5490 Waveform Monitor from Leader implements an algorithm that shows a colored-shade area of the object when focus is achieved. The larger the area covered by the shade is, the more focused it is. This allows you to adjust the camera lens, and see on the monitor or viewfinder when the object is best focused. This function is suitable for scenes with low contrast details and facilitates the focusing of details even in small objects. It provides a visual pattern where the specific scene is focused the most.
