    • A line sensor captures, under predetermined and initialized exposure, at least one of the first negative base area before the first laboratory reserved area, the second negative base area just behind the first laboratory reserved area, the third negative base area just before the second reserved area, and the fourth negative base area behind the second reserved area, and then R, G and B output voltages output from the line sensor are measured. Next, the gain of each of analog amplifiers, or the gain of each of the analog amplifiers and the exposure time of the line sensor are controlled such that each maximum value of the measured R, G and B output voltages corresponds to a predetermined reference voltage. An image of each frame is captured based on the exposure control. Thus, the exposure can be controlled correctly, and a frame image can be captured properly.

    • A plurality of viewpoint images are acquired and images for three-dimensional image display are generated without causing a reduction in polarization performance. Provided are: a first polarization means which has a first polarization region and a second polarization region that each allows different polarized light to be transmitted therethrough; a second polarization means which is made up of a third polarization region that allows only the transmitted light of either one of the first polarization region or the second polarization region to be transmitted therethrough, and a total transmission region that allows the transmitted light of the first polarization region and the second polarization region to be transmitted therethrough; an imaging element into which the transmitted light of the second polarization means is input; and an image processing unit which executes signal processing for an output signal of the imaging element. The image processing unit generates parallax information in which subject distance is reflected by applying a first viewpoint image that is based on the transmitted light of the total transmission region of the second polarization means, and a second viewpoint image that is based on the transmitted light of the third polarization region of the second polarization means, and generates a left-eye-purpose image and a right-eye-purpose image for three-dimensional image display by means of image conversion processing of the first viewpoint image for which the parallax information is applied.
