Claim:
1. A projection method of a wearable projection apparatus, comprising: acquiring color distribution information and brightness distribution information of a plurality of regions of a hand; determining modified color output parameters according to the acquired color distribution information of the regions of the hand and preset standard color information, and determining modified brightness output parameters according to the acquired brightness distribution information of the regions of the hand; and controlling a projection module to output an image according to the determined color output parameters and the determined brightness output parameters, wherein: the determining the modified color output parameters according to the acquired color distribution information of the regions of the hand and the preset standard color information, comprises: the determining the modified color output parameters according to the determined reference color value, the preset standard color information and the acquired color distribution information of the regions of the hand, is performed by calculating using formulae as follows: where, U′(x,y) is a modified red tone output parameter; V′(x,y) is a modified blue tone output parameter; U(x,y) is red tone information in the color distribution information of the regions of the hand; V(x,y) is blue tone information in the color distribution information of the regions of the hand; U
