Problems solved by technology

Therefore, a problem is encountered such that in each frame, the transmitted light in the right area of ​​the shutter and the transmitted light in the left area of ​​the shutter are mixedly received (generated between the right and left viewpoint images). crosstalk), so images from multiple viewpoints (in this case, right and left viewpoint images) cannot be accurately acquired
Since the amount of right and left parallax decreases when crosstalk is generated between viewpoint images in this way, it is difficult to obtain the desired stereoscopic effect (easily recognized as a flat image)

[0069] Overall structure and configuration of the image pickup device 1

[0070] figure 1 The overall structure and configuration of the image pickup device according to the first embodiment of the present disclosure are shown. The image pickup device 1 acquires a plurality of viewpoint images (right and left viewpoint images) as a subject pickup image (still image or moving image). The image pickup device 1 includes image pickup lenses 10 a and 10 b , a shutter 11 , an image sensor 12 , a signal processing / storage section 13 , and a control section 20 .

[0071] Each of the image pickup lenses 10a and 10b is a master lens for taking an image of a subject. For example, a general image pickup lens used in a video camera, still camera, or the like is used as each of the image pickup lenses 10a and 10b. In this case, although the image pickup lens 10a and the image pickup lens 10b are disposed on the light incident side and the light exit side of the shutter 11, respectively, ...

[0105] Figure 10A , Figure 10B and Figure 10C Drive timings of the image sensor and the shutter according to Modification 1 of the first embodiment are respectively shown. That is to say, Figure 10A shows the exposure time period and readout in the image sensor, Figure 10B shows the OPEN and CLOSE switching of the shutter during the low temperature phase, while Figure 10C The OPEN and CLOSE switching of the shutter during the high temperature phase is shown. and, Figure 11A and Figure 11B The response characteristics of the shutter in Modification 1 in the high temperature stage and the response characteristics of the shutter in Modification 1 in the low temperature stage are respectively shown.

[0106] In modification 1, for example, a liquid crystal shutter is used, so that in the low temperature stage, the response from the transmissive state to the light-shielding state is not delayed too much (property d1), while the response from the light-shielding state...

Abstract

The invention provides an image pickup apparatus. In one embodiment, the image pickup apparatus includes an image sensor configured to operate in a line-sequential manner and a shutter device operatively coupled to the image sensor. The shutter device includes regions configured to switch between substantially open states and substantially closed states such that after a first exposure for a first frame is finished, a second exposure for a second frame is started.

Description

technical field [0001] This application claims priority from Japanese Patent Application No. JP2010-058304 filed in Japan Patent Office on Mar. 15, 2010, the entire contents of which are hereby incorporated by reference. Background technique [0002] Various image pickup devices have been proposed and developed. For example, there has been proposed an image pickup device including an image pickup lens and a shutter that is divided into right and left areas and whose opening and closing can selectively switch each divided area. The image pickup device is described, for example, in Japanese Patent No. 1,060,618 ("Patent Document 1"), Japanese Patent Laid-Open No. 2002-34056 ("Patent Document 2"), and JP-A-H09-505906. According to this image pickup device, the opening and closing of the right and left regions of the shutter are alternately switched to each other in a time-divisional manner, thereby switching the transmission light path. Therefore, two kinds of images (a left ...
