Claim 8:
9. The image processing method according to claim 7, wherein determining the target value of each basic color component corresponding to the target color temperature comprises:
determining the target value of each basic color component corresponding to the target color temperature according to a functional relation between each basic color component and a color temperature, wherein
in a case where each basic color component is the red component, the functional relation between the red component and the color temperature is a first functional relation, and the first functional relation is:

F1(x)=A1*log(x/100)+C1,, wherein F1(x) represents a value of the red component, x represents the color temperature, and values of parameters A1 and C1 are obtained by fitting a plurality of coordinate points, between the first basic color temperature Tc_min and the second basic color temperature Tc_max, of a color matching function of the red component by using the first functional relation;
in a case where each basic color component is the green component, the functional relation between the green component and the color temperature is a second a second functional relation, and the second functional relation is:

F2(x)=A2*log(x/100)+C2,, wherein F2(x) represents a value of the green component, x represents the color temperature, and values of parameters A2 and C2 are obtained by fitting a plurality of coordinate points, between the first basic color temperature Tc_min and the second basic color temperature Tc_max, of a color matching function of the green component by using the second functional relation; and
in a case where each basic color component is the blue component, the functional relation between the blue component and the color temperature is a third functional relation, and the third functional relation is:

F3(x)=A3*log((x/100)−10)+C3,, wherein F3(x) represents a value of the blue component, x represents the color temperature, and values of parameters A3 and C3 are obtained by fitting a plurality of coordinate points, between the first basic color temperature Tc_min and the second basic color temperature Tc_max, of a color matching function of the blue component by using the third functional relation.
