The embodiment of the invention provides a defocusing eliminating method and device, and relates to the technical field of electronic equipment. The method comprises the steps that the wavelength range of an imaging light source in a lens is acquired, a target parameter matched with the wavelength range of the imaging light source is searched in a preset database, a light filter having the target parameter can eliminate defocusing caused by the light source within the wavelength range, and the light filter having the target parameter is switched to be between the lens and an imaging sensor. The target parameter matched with the wavelength range is searched in the preset database through the wavelength range of the imaging light source, and the light filter having the target parameter is switched to the lens to eliminate defocusing caused by different wavelength ranges of the imaging light source so that the target parameter is searched by the method through the database, the parameter of the selected light filter is more accurate and defocusing can be completely eliminated in comparison with human experience selection. Besides, manual operation can be omitted by automatically switching the light filter and the operation process can be simplified.
Description
technical field [0001] The invention belongs to the technical field of electronic equipment, and in particular relates to a method and a device for eliminating defocus. Background technique [0002] Defocus is a phenomenon that often occurs in lens imaging. Generally, in the process of optical imaging, for the same shooting point, due to the different wavelength ranges of the light in the imaging light source corresponding to different scenes, the positions where the light is imaged by the lens to the sensor are not coincident, resulting in defocus, such as figure 1 As shown, assuming that infrared light, visible light and ultraviolet light of different wavelength ranges in the imaging light source are incident from the observation object to the lens from the same incident direction, due to the different wavelengths, the refractive index of the lens for infrared light, visible light and ultraviolet light is different, then the infrared The positions where light, visible lig...
