Camera exposure controller including imaging devices for capturing an image using stereo-imaging

A camera exposure controller having at least two imaging devices mounted on a mobile object for taking an image, through stereo-imaging, utilizing incident light from external world in which an object of imaging is present, comprising:

• exposure parameter setting means for generating a brightness histogram of the image taken by the imaging devices and setting exposure parameters including a shutter speed based on the generated brightness histogram;
• high-brightness imaging region removal necessity determining means for determining whether the set exposure parameters are within a predetermined range, and when they are found to be out of the predetermined range, for determining whether a high-brightness imaging region is present in the image due to high-brightness incident light, and when the high-brightness imaging region is present in the image, for determining whether it is necessary to remove the high-brightness imaging region;
• and
• high-brightness imaging region extraction and removal means for extracting the high-brightness imaging region and for removing it from the image, when it is determined that removal of the high-brightness imaging region is necessary.
