Abstract: PROBLEM TO BE SOLVED: To provide an imaging device capable of obtaining a desired viewpoint image without any restriction on the posture in image capturing in one direction. SOLUTION: The imaging device 2 includes: an imaging lens 11; an imaging element 13 for acquiring imaging data on the basis of received light; a liquid crystal shutter 19 divided into four or more regions and capable of controlling a transmissivity for each of the regions; a liquid crystal shutter drive section 14 for switching transmitting and blocking of each of the regions in the liquid crystal shutter 19; and a casing for accommodating the items. Since the liquid crystal shutter 19 is divided into four or more regions, the liquid crystal shutter drive section 14 can select a proper region corresponding to a desired viewpoint direction from the four or more regions in a case where the casing is in a certain posture and a case where it is in another posture different from the certain posture so that the transmitting and blocking can be switched.

Abstract: PROBLEM TO BE SOLVED: To make a tracking servo motor normally started during the recording/reproducing of any of DVD, CD and BD. SOLUTION: A CD and/or DVD objective lens 24 is arranged in a case 38 of an optical pickup so that its moving direction (horizontal direction in the drawing) matches a line through the center of a spindle in the radial direction of an optical disk 100. A BD objective lens 23 is arranged in a position offset from the moving-direction line of the CD and/or DVD objective lens 24. In the case of recording and reproducing the BD, by employing the tracking servo of one of a 1-beam method, a phase shifting DPP method, and a 5-spot DPP, the difficulty of starting the tracking servo motor is alleviated even if recording and reproducing are performed in a plurality of disks. Thus, the tracking servo motor is normally started, and both objective lenses are permitted to access the recording/reproducing area of the innermost periphery of the optical disk 100.
