Image capture control method and apparatus thereof

An image capture control apparatus, comprising:

• a driving unit;
• a lens comprising an aperture and a shutter for capturing image, wherein the aperture and the shutter are connected to the driving unit;
• an image capture unit, capturing the image according to the formation of the image by the lens;
• an analog-to-digital converter connected to the image capture unit, converting analog image signals output by the image capture unit to digital image signals;
• and
• a main control unit connected to the driving unit, driving the driving unit to control the aperture and the shutter, wherein the main control unit is connected to the analog-to-digital converter for accumulatively storing digital image data output by the image capture unit, and evaluating environmental brightness according to the digital image data,
• wherein the main control unit calculates initial shutter exposure period (t) and initial sensitivity (ISO) according to the environmental brightness, and determines whether the initial shutter exposure period is not larger than a predetermined period (T), and, if so, the main control unit drives the driving unit to drive the shutter to capture the image according to the initial shutter exposure period (t) and drives the analog-to-digital converter to process the captured image according to the initial sensitivity (ISO), and otherwise, the main control unit drives the driving unit to drive the shutter to capture the image with the final shutter exposure period (t′) and drives the analog-to-digital converter to process the captured image with the final sensitivity (ISO′) according to a predefined rule.
