Piranha ES-xx User ManualTeledyne DALSA 03-032-20070-02373.3.4 Increasing Sensitivity with BinningBinning increases the cam era’s light sensitivity by d ecreasing horizontal and / or verticalresolu tion—the charge collected by ad jacent pixels is ad d ed together. Binning is alsou sefu l for increasing fram e rate (vertical binning) or increasing the pixel pitch. Forexam ple, if you set you r vertical binning to 2 and you r horizontal binning to 2, you r pixelsize increases from 7μm x 7μm (no binning) to 14μm x 14μm (2x2 binning).Figure 12: 2x2 Binning in Area ModeSetting Horizontal BinningPurpose: Increases the horizontal pixel pitch and light sensitivity byd ecreasing horizontal resolution. The amount of d ata bein g sentfrom the camera is red uced by the horizontal binning factor.Different frame grabber files are need ed for d ifferent horizontalbinning factors.Syntax: sbh mSyntax Elements: mH orizontal binning value. Available values are 1 (factorysetting, no binning) 2, 4, or 8 (ES-80 mod el only)N otes:  If you are using horizontal binning, the min, max, and meanstatistics generated by the gl or gla command are for everysecond pixel (or valid d ata) only (e.g., if sbh 2, every secondpixel). For optimal flat field correction, you should rerun the ccp andccf command s after changing binning values. Changing binning values d oes not automatically alter gain,frame rate generation, or other functions of the camera. Pixel numbering remains unchanged for the roi, gl, gla,dpc, gfc, sfc, gpc, and spc command s. Refer to Figure 13for an explanation of pixel numbering and pixel start and stopvalues w hen using a region of interest.Example: sbh 2
