<p>PROBLEM TO BE SOLVED: To reduce the imaging sensitivity without degrading a dynamic range.SOLUTION: A head of an imaging device includes: an imaging device having a rolling shutter function, for outputting an image in analog signal corresponding to an amount of light from a subject; an analog amplifier for increasing or attenuating a signal level of an analog signal from the imaging device; and a conversion part for clipping a digital signal obtained by converting the analog signal inputted from the analog amplifier, if the signal level of the digital signal exceeds a maximum output level, and outputting the digital signal. The analog amplifier attenuates the level of the analog signal from the imaging device within a range in which the digital signal outputted from the conversion part keeps the maximum output level, for a case of minus gain input.</p> |
