Figure 4. Two-dimensional imaging of spontaneous ultra-weak photon emission from Arabidopsis plant using software and hardware binning.

(A), Two-dimensional imaging of ultra-weak photon emission measured with software binning mode and variable accumulation time. (B), Two-dimensional imaging of ultra-weak photon emission measured with hardware binning mode and variable accumulation time. Accumulation times were kept 10 min, 20 min and 30 min. The accumulation time (x-axis) versus the binning factor (y-axis) were analyzed. The binning factor ranges from 1 × 1 to 4 × 4.
