Benefits of technology

[0009]The present invention provides an image device for generating depth images and related electronic device. Because the image device utilizes a rotating device to rotate a plurality of image capturers included in the image device, and utilizes a processor to generate a depth image according to plurality of images captured by the plurality of image capturers, compared to the prior art, the image device does not have a problem that optical centers in the prior art cannot overlap. In addition, because a 360 degree panoramic color and depth image generated by the present invention has depth information of a 360 degree panoramic depth image, compared to the prior art, when the electronic device displays the 360 degree panoramic color and depth image, the electronic device can display a corresponding planar color and depth image according to motion or rotation of the electronic device

Problems solved by technology

However, because optical centers of a plurality of image capturers included in the each image capturing group cannot completely overlap (that is, a mechanism of the image device has an intrinsic defect), the image device first needs to execute image processing on a plurality of images captured by the plurality of image capturers (e.g. integrating the optical centers of the plurality of image capturers into a virtual optical center) to generate the 360 degree panoramic depth image, otherwise a problem of blind spots will occur at stitching regions of the 360 degree panoramic depth image.
Therefore, how to solve the above-mentioned problems of the prior art becomes an important issue.

FIG. 1 is a diagram illustrating an image device 100 for generating depth images according to the present invention, wherein as shown in FIG. 1, the image device 100 includes two image capturers 102, 104, a supporting unit 106, a rotating device 108, and a processor 110, the supporting unit 106 is coupled to the rotating device 108, the processor 110 is coupled to the image capturers 102, 104, the image capturers 102, 104 are installed on the supporting unit 106, and the image capturers 102, 104 are non-fisheye image capturers. But, in another embodiment of the present invention, the image capturers 102, 104 are fisheye image capturers. In addition, the present invention is not limited to the image device 100 including the image capturers 102, 104. That is, the image device 100 can include more than two image capturers. In addition, one of ordinary skill in the art should well know that each image capturer of the image capturers 102, 104 at least includ...

second embodiment

[0020]Please refer to FIG. 3A. FIG. 3A is a diagram illustrating an image device 300 for generating depth images according to the present invention, wherein as shown in FIG. 3A, differences between the image device 300 and the image device 100 are that the image device 300 further includes a light source 302, an image capturer 304 are used for capturing a plurality of second images including emission light generated by the light source 302, the processor 110 is coupled to the light source 302, the image capturer 304, and the image capturer 102, and the light source 302, the image capturer 304, and the image capturer 102 are installed on the supporting unit 106. In addition, the emission light is structured light (or the emission light includes a random pattern), and the light source 302 utilizes a collimator, at least one laser beam (e.g. at least one infrared laser beam), and at least one optical element (e.g. at least one diffraction optical element (DOE) to generate the emission ...

third embodiment

[0030]Please refer to FIG. 4. FIG. 4 is a diagram illustrating an electronic device 400 for viewing a panoramic color and depth image according to the present invention, wherein as shown in FIG. 4, the electronic device 400 includes a display 402, a processor 404, and an inertial sensor 406 (e.g. an inertial measurement unit, IMU), the processor 404 is coupled to the display 402 and the inertial sensor 406 (because the processor 404 and the inertial sensor 406 are installed within the electronic device 400, related coupling lines corresponding to the processor 404 and the inertial sensor 406 are represented by dotted lines), and the inertial sensor 406 can be a gyro, an accelerator, a microelectromechanical systems (MEMS), and so on.

Abstract

An image device for generating depth images includes at least two image capturers and a rotating device. When the rotating device rotates the at least two image capturers, multiple images captured by the at least two image capturers are utilized to generate a depth image, wherein a view angle corresponding to the depth image is not less than a view angle of each image capturer of the at least two image capturers.
