The PD module may be configured to provide a control signal to an electromechanical device, such as a voice coil motor (VCM), of an image capture module to move a lens assembly to focus an image of an object to be imaged onto a primary image sensor. The PD module may direct the capture of a PD image by the PD image sensor and perform a phase detect (PD) technique on the captured AF image to identify a focus point of the lens assembly. This determined focus point may be used to displace the lens assembly relative to the primary image sensor to achieve focus of the object onto the primary image sensor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Phase detect auto-focus","description":"An phase detect (PD) module including a phase detect (PD) lens, PD image sensor, and a PD controller is disclosed.
