Embodiment Construction

[0045] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.

[0046] figure 1 It is an exemplary flow chart of a method for processing a special lighting effect in an embodiment of the present invention. Such as figure 1 As shown, the process includes the following steps:

[0047] Step 101, scan each pixel in the image to be processed, and determine the pixel that needs to emit light.

[0048] In this step, it may be determined that a pixel point whose luminance value is greater than a set threshold is a pixel point that needs to emit light. For example, the value range of the set threshold may be [120, 255], and the threshold may be 240 in this embodiment.

[0049] Step 102, for each determined pixel point, with the pixel point as the center point, select a corresponding number of pixel points along ea...

Abstract

The invention discloses a light-emitting special effect processing method and a device; the method comprises the following steps: determining the pixel points which need to emit light in a pending image; respectively taking each pixel point as the central point, and respectively selecting pixel points of corresponding number from each set direction based on a set light-emitting length; taking each selected pixel point and each pixel point which is regarded as the central point as pending pixel points, and calculating the brightness coefficient value of each pending pixel point according to the location relationship between each pending pixel point and the corresponding central point; for each pixel point whose brightness coefficient value is not 1, processing light-emitting treatment to the pixel point based on the brightness coefficient value of the pixel point so as to obtain an image with light-emitting special effect. The technical proposal provided by the invention can achieve specific light-emitting effects in finished shot images.

Description

technical field [0001] The invention relates to image processing technology, in particular to a method and device for processing luminous special effects. Background technique [0002] With people's demand for various special effects of images, there are currently many image processing methods, such as image stitching, image mosaic processing, image contrast adjustment, etc. In addition, in order to create a special light effect, in the prior art, a special lens, such as a Pozi mirror or a cross mirror, is usually added to achieve a specific light effect of the captured image when shooting. In practical applications, it is sometimes necessary to achieve a luminous special effect similar to that achieved by the above-mentioned Pozi mirror or cross mirror for the image that has been captured, but this cannot be achieved in the prior art. Contents of the invention [0003] In view of this, the present invention provides, on the one hand, a method for processing special li...
