The invention discloses a light field camera and its photometric adjustment method, device and electronic equipment. The method includes: acquiring a light field image through a micro-microscope array; calculating the gray value of the light field image according to the light field image; The gray value of the light field image is calculated by setting the median value and the preset compensation value to obtain a light intensity adjustment value; the intensity of the light field image is adjusted according to the light intensity adjustment value to obtain an adjusted light field image. The light intensity adjustment method of the light field camera provided by the embodiment of the present invention calculates the gray value of the light field image according to the preset median value and the preset compensation value by calculating the gray value of the light field image to obtain the light intensity adjustment value , and adjust the light field image according to the light intensity adjustment value, which can improve the spot problem caused by spatial light for imaging, and can also locally adjust any light intensity, thereby improving the local light intensity drop.
Description
technical field [0001] The present invention relates to the technical field of light field cameras, in particular to a light field camera and its photometric adjustment method, device and electronic equipment. Background technique [0002] The light field camera based on the micromicroscope array applies light field imaging technology, which can simultaneously record the two-dimensional position information and two-dimensional direction information of the space object through a single exposure, and is currently the mainstream light field acquisition device. The difference between a light field camera and an ordinary camera is that a light field camera places a microlens array on the imaging surface between the main lens and the detector, which divides the pupil of the main mirror into several sub-apertures, and each microlens passes through each The aperture acquires light from the same position in different directions in the target scene, thereby realizing the collection of...
