3D imaging module and 3D imaging method

Abstract

The invention relates to a 3D (Three Dimensional) imaging module which comprises a first imaging unit, a second imaging unit, a memory, a color separating unit, a processor, an image processing unit, a focusing drive unit, optical image stabilizing units and an image synthesis unit, wherein the first imaging unit and the second imaging unit are used for capturing images in the same scene at different angles simultaneously; the color separating unit is used for showing the images captured by the first imaging unit and the second imaging unit with three primary colors namely red, green and blue respectively; the processor is used for determining a current shoot mode; the optical image stabilizing units are used for correcting jitter before shooting; the image processing unit is used for performing out-of-focus fuzzy modification in a software compute simulation mode; and the focusing drive unit focus the first imaging unit and the second imaging unit. The invention further relates to a 3D imaging method.

Description

technical field [0001] The invention relates to an imaging module, in particular to a 3D imaging module with an automatic focus function and a 3D imaging method. Background technique [0002] With the advancement of technology, 3D (three-dimensional) imaging modules have been increasingly used in many fields, and in order to achieve better imaging effects, 3D imaging modules are also required to have an auto-focus function. [0003] The auto-focus technology of the imaging module is divided into mechanical auto-focus technology and digital auto-focus technology. Mechanical autofocus technology uses a mechanical structure to move the lens inside the lens to focus. Since the mechanical focusing technology needs to adopt a complicated mechanical structure, the cost of the auto-focus lens increases and the volume is relatively large. [0004] Digital auto-focus technology uses software simulation and calculation to process the image sensed by the image sensor, so that the blur...

Problems solved by technology

However, the defect of digital autofocus is that it is not capable of short-range imaging. Generally speaking, if the object distance is within 40cm, the focusing effect of digital autofocus technology is often unsatisfactory.

In addition, if there is shaking during the shooting process, the EDoF technology will not be able to fully function, resulting in a decline in the imaging effect of the imaging module
