Dynamic device 71 and optical filter 72, further include light acquisition module 73.In the present embodiment, light acquisition module 73 is light level
Device, light sensor are used to detect the light luminance under current shooting environment, when the light intensity value of external environment is lower than default
When luminance threshold, the processor of terminal sends the control signal that optical filter is removed to daylighting path, driving device to driving device
Optical filter is moved on to except daylighting path according to control signal, so that infrared light is able to enter camera module and is conducive to imaging；Work as outside
When the light intensity value of environment is higher than predetermined luminance threshold value, the processor of terminal is sent to driving device moves into daylighting for optical filter
The control signal in path, driving device move on to optical filter on daylighting path according to control signal, and infrared light is stopped to enter camera shooting
Mould group, so as to normally be shot.
Present embodiments provide a kind of camera module, which includes driving device and optical filter, driving device with
Optical filter connection, controls the optical filter and is moved on the daylighting path except the daylighting path of the camera module, or
It is moved to from the daylighting path except the daylighting path, solving terminal camera in Related Technical Issues is that fixation is set
Set irremovable, when which results in being shot under the environment of night or light difference, infrared light can be also filtered out, and be made
The problem for obtaining imaging effect difference, realizes the effect that terminal camera can be also clearly captured under night or low light environment.
Second embodiment
Fig. 8 is the flow chart for the filming control method that second embodiment of the invention provides, which includes:
