PROBLEM TO BE SOLVED: To provide an imaging apparatus capable of accurately detecting a focal position independently of a change in the transfer efficiency or the like. SOLUTION: A transfer efficiency detecting unit 70 is a unit for detecting the transfer efficiency of a CCD 36. A camera sensitivity detecting unit 72 acquires sensitivity (ISO) information of the CCD 36 established at photographing. A light source color temperature detection unit 74 acquires color temperature information of a light source calculated by a CPU 10. A drive frequency detection unit 76 acquires a drive pulse frequency (drive frequency of the CCD 36) outputted from a TG 48. An enclosure temperature detection unit 78 detects the temperature of an enclosure of a camera 10. A focus peak detection unit 80 detects a focus peak position by the CPU 10. A focus peak correction unit 82 corrects the focus peak position (detected value). The focus peak detection unit 80 outputs the corrected focus peak position to the CPU 10. The CPU 10 carries out focus control on the basis of the corrected focus peak position. COPYRIGHT: (C)2007,JPO&INPIT |
