Camera module and electronic device

Abstract

Camera module (1) comprising: an imaging lens (13) with a central axis (CA); a drive module (10) configured to drive the imaging lens (13) to move along a direction of the central axis (CA); and a positioning module (14) comprising: a positioning light emission module (140); a positioning light receiving module (141) configured to receive emitted light from the positioning light emission module (140); and a positioning light shielding film (142) configured to move synchronously with the imaging lens (13);wherein, when the imaging lens (13) is moved along the direction of the central axis (CA), the positioning light shielding film (142) at least partially blocks the light emitted by the positioning light emission module (140), the light intensity of the emitted light received by the positioning light receiving module (141) changes, and the positioning light shielding film (142) moves, and the positioning light receiving module (141) outputs a corresponding positioning signal according to the light intensity.
