Latest Patents

Ivan Vasilev holds a patent for a "Camera flash module and method for controlling same." This invention utilizes an auto-exposure algorithm that employs image processing to identify critical areas of an image affected by the flash. The algorithm effectively disregards highly reflective or illuminated areas and incorporates a neutral density (ND) filter to linearize flash triggering in such scenes. The control of the camera flash is executed in two stages: a pre-flash stage followed by a main-flash stage. During the pre-flash stage, two images are captured under identical camera settings, one with flash and one without. The difference between these images allows for the determination of flash intensity in the main-flash stage.
