Title:
IMAGING MECHANISM AND FORWARD SURVEILLANCE CAMERA USING SAID IMAGING MECHANISM
Document Type and Number:
WIPO Patent Application WO/2013/161495
Kind Code:
A1
Abstract:
An imaging mechanism (7) provided in a forword surveillance camera can adjust, without using a mechanical constitution, light intensity brought into an image sensor (70) by adjusting the light intensity passing through a liquid crystal shutter (73) disposed in an adjusting part. For example, when the light intensity is great during the day, or the like, the resolution of images taken during the day can be improved by the light passing through the adjusting part being shielded and the light intensity brought into the image sensor (70) being reduced. When there is little light intensity at night, or the like, the brightness of images taken at night can be improved by light passing through the adjusting part and the light intensity brought into the image sensor (70) being increased.
