摘要：
This paper focuses on high speed video acquisition system designing for biomedical image enhancement. The paper gives information about microscope dimmer using in image analysis. Due to fast digital camera, system contains intelligent illumination dimming hardware automatically regulated through measurement card. Regulating parameter for dimmer (PWM duty cycle) is computed from image features, histogram distribution and intensity relations. Dimming helps system to preserve optimal acquisition light conditions for accurate image/sequence processing and eliminates abnormal heat generation in microscope condenser when using high-power lamp.
