The invention provides a self-adaptive lens shadow correction method based on color temperature and illumination, and the method comprises the steps: S1, obtaining a to-be-corrected original image of a video image, and guaranteeing the brightness of the image to be in the degree of human eye vision; s2, extracting four channels of the to-be-corrected image, including a red channel R, green channels Gr and Gb, and a blue channel B; s3, calculating four channel correction coefficients, including Rgain, of the image; grgain and Gbgain are selected from the group consisting of Grgain and Gbgain; bgain, Bgain; the formula is as follows: R < gain > = R < gain > org * R < stream >; grgain is equal to Grgainorg * Grstream, and Grgain is equal to Grgainorg * Grstream; gbgain is equal to Gbgainorg * Gbstream, and Gbgain is equal to Gbgainorg * Gbstream; bgain is equal to Bgain org * Bstream, and Bgain is equal to Bgain org * Bstream; wherein the Rgain, the Grgain, the Gbgain and the Bgain are respectively corresponding channel correction coefficients; the Rstream, the Grstream, the Gbstream and the Bstream are respectively corresponding correction intensities, and the Rgainorg, the Bgainorg, the Grgainorg and the Gbgainorg are respectively static correction coefficients of corresponding channels; s4, correcting four channels of the image, and performing table look-up and calculation on coefficients of corresponding positions to obtain a formula r = R * Rgain; gr is equal to Gr * Grgain; gb is equal to Gb * Gbgain; b is equal to B * Bgain.
