Abstract
An image capturing method with supplemental lighting modulation is applied to a monitoring apparatus having a lighting unit and an image detecting unit. The image capturing method includes dividing a working period of the lighting unit into at least one first sub-period and at least one second sub-period, driving the lighting unit to respectively output supplemental light with different intensity during the first sub-period and the second sub-period, driving the image detecting unit to respectively capture a set of monitoring images with a predetermined amount during the first sub-period and the second sub-period, comparing the monitoring image captured in the first sub-period with ones captured in the second sub-period, analyzing definition of the set of monitoring images, and selecting a corresponding monitoring image having the definition greater than a threshold to execute image recognition.
