Overview Partial scan output image format It is equipped with a partial scan feature that divides an entire screen image into 16 × 16 sections, allowing it to be output as an optionally designated rectangle within the required limits. Use of this function enables frame rates faster than normal speeds, thus enabling efficient image capture. In addition, partial scan operations can be carried out even without the input of an external trigger. C-mount High vibration-resistance structure Binning The

Functions Binning Mode The mode used when the sensitivity is increased and the frame rate is multiplied based on mixing the CCD pixel data, is called the Binning mode. There are two types of binning: 1 × 2 binning when the output image is compressed in the vertical direction only, and 2 × 2 binning when the image is compressed in the horizontal direction also. When binning mode is used, set either Format7 Mode 1 (2 × 2 binning), or Format7 Mode 2 (1 × 2 binning). The specifications for each mode
