Embodiment approach 2

[0139] Below, refer to Figure 8 , 9 A second embodiment of the present invention will be described. The imaging device of this embodiment differs from the imaging device of Embodiment 1 in the basic pixel configuration of the imaging element 1 and the method of acquiring an image representing parallax. Hereinafter, only the differences from the imaging device of Embodiment 1 will be described, and the description of the same parts will be omitted.

[0140] Figure 8 The basic pixel configuration on the imaging surface of the solid-state imaging device 1 in this embodiment is shown. In this embodiment, a pixel is constituted by a plurality of pixel blocks basically constituted by two rows and two columns, and a color element (color filter) or a polarizing filter is arranged to face each pixel. The color element in this embodiment is a known color filter that transmits only light in a wavelength range having a specific color component. In addition, in the following descrip...

Abstract

Disclosed is an image capture device, comprising an image forming lens (3), a light transmission unit (2) further comprising two polarizers, a rotation drive unit (2A) that rotates the light transmission unit (2), and a solid-state image capture element (1). The solid-state image capture element (1) further comprises a plurality of pixels and polarizing filters corresponding to the pixels. A first polarizing filter (50a) is positioned corresponding to a first pixel group (W1), and a second polarizing filter (50b) is positioned corresponding to a second pixel group (W2). The directions of the transmission axes of polarization regions (P(1), P(2)) in the light transmission unit (2) vary respectively by an angle a. The directions of the transmission axes of the polarization filters (50a, 50b) vary respectively by an angle ss. The rotation drive unit (2A) is capable of rotating the light transmission plate (2) with the direction of the optical axis of the incident light being the direction the axis of rotation. It is thus possible to obtain a plurality of sets of multiple-viewpoint images.

Description

technical field [0001] The present invention relates to a single-lens three-dimensional imaging technology that uses an optical system and an imaging element to obtain multiple images with parallax. Background technique [0002] In recent years, digital still cameras and digital video cameras employing imaging elements such as CCDs and CMOSs ​​have surprisingly achieved higher functionality and higher performance. Especially with the advancement of semiconductor manufacturing technology, a high degree of refinement has been developed, and high integration has been realized. The imaging element has also advanced from 1 million pixels to 10 million pixels to achieve high pixel count, and the captured images have also achieved high-quality images by leaps and bounds. In addition, the display device also achieves space saving due to the thin liquid crystal or plasma display, and realizes high-resolution, high-contrast performance. Such high-quality images are trending, and tar...
