○View mode (Current model)
Pseudo Color View   Contour View   Split Spot
擬似カラーs.jpg   等高線ビューs.jpg   分割スポットs.jpg
The difference in luminance or color on the image is presented by using colored image.
Suited for Mura evaluation
  Indicates the luminance and color difference by using contour line.   Image is dividend with grid pattern and show value of luminance and chromaticity in each gird.

Standard Spot View   Random Spot View   Cross Section View
規格スポットs.jpg   任意スポットs.jpg   断面図ビューs.jpg
Four type of measurement according to JEITA standard (EIAJ ED-2522/ED-2710). shape and quantity of spots are changeable.   999 points at max can be placed on the image.   Measured data on the cross-section line is shown as graph. The cross-section line can be selected from cross line and diagonal line.

Color diagram View(x,y/u',v')   3D View   Histogram View

Measured data on each view can be plotted on the color diagram   Measured data show as 3D image.   Statistical graph.
Vertical axis means the frequency, horizontal axis means measured data.

Thumbnail View   Time-series graph view    
サムネイルビューs.jpg   時系列ビューs.jpg    
Measured images show as thumbnails.   Variation of measured data with lapse of time shows    

Measured data on each view can be saved as csv format.
Image on each View can be saved as BMP/JPG/PNG file.
