Optical field collecting control method and device and optical field collecting equipment

Abstract

An embodiment of the invention discloses an optical field collecting control method and device and optical field collecting equipment. The optical field collecting control method includes: acquiring the main lens aperture parameters of an optical field camera; determining part of the imaging area, corresponding to at least one sub-lens in the sub-lens array of the optical field camera, in the image sensor of the optical field camera as a first imaging area; adjusting the pixel density distribution of the image sensor to allow the pixel density of the adjusted first imaging area to be different from that of the other parts of the imaging area; using the adjusted optical field camera to perform optical field collecting on a to-be-shot scene. The method has the advantages that image sensor pixel utilization rate during optical field collecting performed by the optical field camera on the to-be-shot scene is increased, and optical field image imaging quality is increased.

Description

technical field [0001] The present application relates to the field of light field acquisition technology, in particular to a light field acquisition control method and device and a light field acquisition device. Background technique [0002] A light field camera is an imaging technology that uses a sub-lens array to record and reproduce a three-dimensional scene. It usually places a sub-lens array between the main lens and an image sensor such as a CCD. Light field information is recorded on the focal plane of the sub-lens array. [0003] Different from the two-dimensional image acquisition method of the traditional camera, the light field camera can record four-dimensional light field information such as the space and angle of view of the three-dimensional scene through a single exposure, and supports "focusing after shooting" (that is, no need to focus when shooting), through Rich image effects can be generated by processing the captured image, which can satisfy one or ...

[0004] However, although the light field camera increases the above-mentioned flexibility of single-exposure imaging, the light field camera records the viewing angle direction information of the object light by losing the spatial resolution of the image, and collects the light field of the scene to be photographed based on the light field camera During the process, the image sensor of the light field camera has limited image sensor pixels for light field acquisition, some image sensor pixels do not participate in light field acquisition, and the pixel utilization rate of the image sensor is low, which affects the imaging of light field images quality
