The invention discloses a light field camera, a luminosity adjusting method and device thereof and electronic equipment. The method comprises the following steps: acquiring a light field image passingthrough a micro microscope array; calculating a gray value of the light field image according to the light field image; calculating the gray value of the light field image according to a preset median and a preset compensation value to obtain a light intensity adjustment value; and adjusting the intensity of the light field image according to the light intensity adjustment value to obtain an adjusted light field image. The embodiment of the invention provides the luminosity adjusting method of the light field camera. The gray value of a light field image is calculated; the gray value of the light field image is calculated according to the preset median and the preset compensation value, the light intensity adjustment value is obtained, and the light field image is adjusted according to the light intensity adjustment value, so that the problem of light spots caused by spatial light to imaging can be improved, any light intensity can be locally adjusted, and the locally generated lightintensity fall is improved.
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...
