Abstract:
PROBLEM TO BE SOLVED: To output clear images by reducing blooming even when a strong light source such as the head lamp of an oncoming car is present at night. SOLUTION: This image pickup system is provided with an IR lamp for irradiating the front part with infrared rays, a CCD camera 5 for imaging the front part, and for converting it into an electric signal and an image processing unit 7 for continuously and periodically outputting images whose exposure is different by changing the signal storage time of the CCD camera 5 in predetermined periods. The image processing unit 7 sets a mask for adjusting the luminance levels of images in ODD fields and EVEN fields whose exposure is different in the images in the ODD fields whose luminance level is high.
