IMAGING UNIT, IMAGING APPARATUS AND COMPUTER-READABLE MEDIUM HAVING STORED THEREON A CONTROL PROGRAM |
摘要 |
There is a demand for increasing the dynamic range of an imaging unit. Provided is an imaging unit comprising a pixel section that outputs a pixel signal corresponding to a reset potential after a reset and a signal potential after charge accumulation; an amplifying section that amplifies the pixel signal with a first amplification ratio or a second amplification ratio that is different from the first amplification ratio; and a control section that causes the amplifying section to amplify the pixel signal corresponding to a change from the reset potential to the signal potential with the first amplification ratio, and then causes the amplifying section to amplify the pixel signal corresponding to a change from the signal potential to the reset potential with the second amplification ratio. |

1. An imaging unit comprising:
a pixel section that outputs a pixel signal corresponding to a reset potential after a reset and a signal potential after charge accumulation; an amplifying section that amplifies the pixel signal with a first amplification ratio or a second amplification ratio that is different from the first amplification ratio; and a control section that causes the amplifying section to amplify the pixel signal corresponding to a change from the reset potential to the signal potential with the first amplification ratio, and then causes the amplifying section to amplify the pixel signal corresponding to a change from the signal potential to the reset potential with the second amplification ratio. |
