A projection device and a projection method, a projection module, an electronic device, and a program that correct a misalignment of an optical axis are disclosed. Test emission is performed of a laser beam that is a light source in a projector, and a position of the optical axis of the laser beam is obtained from a ratio of an amount of light detected by a photodetector divided into a plurality of areas that is a two-dimensional plane perpendicular to the optical axis. The misalignment of the optical axis is obtained on the basis of information regarding a position of the optical axis of each of R, G, and B, a correction coefficient is calculated for correcting a shift of a pixel position on a projection image projected on a screen, and a pixel position to be projected is corrected with the correction coefficient and projected with RGB misalignment correction.
