Embodiment Construction

[0038] Next, an imaging device 1 according to an embodiment of the present invention will be described with reference to the drawings.

[0039] Such as figure 1 As shown, the imaging device 1 of the present embodiment includes: an imaging unit 2 that captures a subject A to obtain image information; and an image processing unit 3 that processes the image information obtained by the imaging unit 2 .

[0040] Such as figure 1 As shown, the imaging unit 2 has: an imaging lens 4, which converges the light from the subject A; an aperture member 5, which is arranged adjacent to the imaging lens 4; a microlens array 6, which passes through the aperture member 5 and forms The light behind the real image B is incident on the microlens array 6 ;

[0041] Such as figure 2 As shown, the aperture unit 5 has: an ordinary aperture portion 5a having a substantially circular opening through which a part of the light from the subject A converged by the imaging lens 4 passes; The ordinary a...

Abstract

The subject distance can be obtained with high precision, and a high-quality image can be obtained. An imaging device (1) is provided, the imaging device (1) has: an imaging lens (4), which converges light from an object (A); an aperture member (5), which is adjacent to the imaging lens (4) configuration; imaging element (7), which photographs the light that is converged by the imaging lens (4) and passes through the aperture part (5); Between the element (7) and the imaging lens (4), the aperture unit (5) has: at least one ordinary aperture section with a substantially circular opening; and at least two coded aperture sections with predetermined pattern openings.

Description

technical field [0001] The present invention relates to imaging devices. Background technique [0002] Conventionally, an imaging device using a microlens array has been proposed (for example, refer to Patent Document 1). [0003] This imaging device includes a microlens array in which a plurality of pixels are assigned to each lens between an imaging lens and a sensor. According to this imaging device, a plurality of parallax images can be obtained simultaneously, and by performing known stereo matching processing, the distance between the subjects can be measured at any point on the subject. [0004] prior art literature [0005] patent documents [0006] Patent Document 1: Japanese Patent No. 4752031 Contents of the invention [0007] The problem to be solved by the invention [0008] However, when a subject with little texture information is captured or blurred, the accuracy of the stereo matching process decreases and there is a problem that the distance cannot b...
