Patent ID: 7932935

Claim:
An imaging apparatus comprising: an imaging unit configured to image an object; a gain adjustment unit configured to adjust a gain for an image signal output from the imaging unit; a signal processing unit configured to process the image signal, the signal processing unit including a first noise reduction unit to reduce a particular noise included in the image signal; an image compression unit configured to compress an image signal output from the signal processing unit, the image compression unit including a second noise reduction unit to reduce a particular noise included in the image signal output from the signal processing unit; and a control unit configured to, when the gain adjustment unit is increasing the gain for the image signal output from the imaging unit, transmit a control signal to both the first and second noise reduction unit, and one of (i) set the first noise reduction unit into an operative state and the second noise reduction unit into an inoperative state and (ii) set the second noise reduction unit into an operative state and the first noise reduction unit into an inoperative state.
