PROBLEM TO BE SOLVED: To provide an imaging apparatus effective in imaging of an object with a very large luminance difference and an object changing time by time by varying a dynamic range magnification factor of camera at a high-speed depending on the luminance difference in the object so as to obtain an imaged image optimized for the object luminance difference. SOLUTION: The dynamic range magnification factor in response to the luminance difference of the object can be obtained from the imaging apparatus 20 by using a control means 24 to control a shutter speed depending on the luminance difference of the object in the case of obtaining first and second image signals through imaging. Further, the imaging apparatus 20 adopts a CMOS sensor 28 for the imaging element, reads the image signal obtained by imaging at a high-speed and an area selection extract means 113 selects and extracts optional image information to limit an information amount for the image signal subjected to signal processing thereby reducing a time required from the imaging until output of the image signal.
