PROBLEM TO BE SOLVED: To obtain a satisfactory captured image while reducing a burden of hardware constituting an imaging apparatus as further as possible during imaging by the imaging apparatus.SOLUTION: An imaging apparatus acquires IQL(K) (an identification performance limit value) which is set in accordance with the quantity of a noise component as a value capable of identifying a preset target from among a plurality of reference images which are picked up beforehand in the imaging apparatus during table creation processing (S104). An analog gain value in the case of obtaining a captured image from an imaging signal obtained from an imaging device in the imaging apparatus 1 is set while considering IQL(K) (S107) and in the case of setting to the analog gain value, a shutter time capable of obtaining preset luminance in the captured image is set for each estimated imaging signal size (S108). Further, a control table recording therein a relation between the analog gain value and the shutter time is generated for each imaging signal size (S109). |
