This application discloses a method, apparatus, and electronic device for generating lens flare. The method includes: generating a set of patches corresponding to the lens flare based on its attribute information; obtaining a set of sequence maps corresponding to the patch set; determining the sampled texture coordinates of the multi-frame textures based on the original texture coordinates of the patch set and the region information of the areas where the multi-frame textures are located in the sequence map set; sampling the sequence map set based on the sampled texture coordinates of the multi-frame textures to obtain the texture information of the patch set; and generating the lens flare based on the texture information of the patch set. This application solves the technical problems of complex lens flare generation processes and poor generation effects in related technologies.

This invention relates to the field of optical inspection equipment technology, and particularly to a rapid lens flare detection device, comprising: a driving mechanism, a planar LED inspection mechanism, and a multi-field-of-view screening mechanism; the planar LED inspection mechanism and the multi-field-of-view screening mechanism respectively perform rapid inspection and screening of lens flare, using real imaging conditions to assist in evaluating the degree of lens flare. The driving mechanism includes: a linear module, a sliding module, an L-shaped support plate, and a tray; the linear module is symmetrically fixed on a horizontal working platform, and the sliding module is installed at the driving end of the linear module, driving the sliding module to slide and adjust on the X-axis; several L-shaped support plates are installed at the driving end of the sliding module, driving the L-shaped support plates to slide and adjust on the Y-axis. This invention enables multi-station planar rapid inspection, combined with multi-field-of-view point light source screening of lens flare degree, improving inspection efficiency and reducing the risk of missed detection.

A method for eliminating lens flare that eliminates lens flare is provided. The lens flare elimination method performs: a step for acquiring images by irradiating the coaxial episcopic illumination light with varying irradiation intensities and capturing images at each irradiation intensity while the object is not placed on the mounting table; a step for capturing an image of the object by irradiating the object placed on the mounting table with the coaxial episcopic illumination light at an arbitrary irradiation intensity; a step for estimating an image for correction, which is the image at the irradiation intensity irradiated when the measurement object is captured, based on the images acquired in the image acquiring step; and a step for generating a post-correction image in which the lens flare is eliminated from the image of the object by obtaining the difference between the image of the object and the image for correction.
