[0097] The second embodiment is a modification of the first embodiment. In the first embodiment, the first area passes the light L 1 The direction of the electric field is parallel to the first direction. Meanwhile, in the second embodiment, the first area passes through the light L 1 The direction of the electric field forms an angle of 45 degrees with the first direction. The polarization states of the first polarizing unit 230 and the second polarizing unit 250 included in the imaging device according to the second embodiment are schematically illustrated in Figure 6A with 6B middle.

[0098] exist Figure 7 A conceptual diagram of an imaging element array 40 having a Bayer arrangement is illustrated in . Even in the second embodiment, in the imaging element array 40, one pixel includes four imaging elements (a red imaging element R for receiving red light, a blue imaging element B for receiving blue light, and two Green imaging element G) for receiving green light....

[0101] The third embodiment is also a modification of the first embodiment. In the imaging device according to the third embodiment, in the first polarizing unit 330, a central region 333 is provided between the first region 331 and the second region 332, and the central region that has passed through the central region 333 passes through the polarization state of light does not change from the polarization state of the light prior to being incident on the central region 333 . That is, central region 333 is polarization independent.

[0102] Meanwhile, when the incident light passes through the first polarizing unit, the amount of light decreases in proportion to the spectral characteristics and extinction ratio, and its brightness becomes dim. In this case, the extinction ratio is the ratio of the amount of light to be selected and passed by the polarizer to the amount of leaked light not selected by the polarizer and to be reflected or absorbed. Specifically, in the case o...

Abstract

There are provided an imaging apparatus and an imaging method. The imaging apparatus includes a first polarizing unit that polarizes light from an object, a lens system that condenses light from the first polarizing unit, and an imaging element array that has imaging elements arranged in a matrix of a first direction and a second direction orthogonal to the first direction and a second polarizing unit arranged on a light incident side, and converts the light condensed by the lens system into an electric signal.

Description

technical field [0001] The present disclosure relates to an imaging device and an imaging method, and more particularly, to an imaging device and an imaging method for imaging a subject as a stereoscopic image. Background technique [0002] In the related art, there has been proposed a system for simultaneously imaging a common subject using two cameras arranged on the left and right sides, simultaneously outputting two kinds of obtained images (a right-eye image and a left-eye image), and displaying Stereoscopic image. However, when two cameras are used, the size of the device may increase, and using two cameras is not practical. Regardless of the zoom ratio of the lenses, the baseline length between the two cameras, ie the interocular distance for a stereo camera, is typically about 65 mm, which corresponds to the interocular distance of a human. In this case, binocular disparity may increase in the enlarged image, and this forces information processing different from no...
