Abstract: A camera system may include circuitry for measuring the positions of an optics assembly (e.g., one or more lenses) and/or an image sensor of the camera system. The circuitry may include analog circuits comprising a first and a second position sensors to produce a first and a second sensor signals based on a first magnetic field and a second magnetic field respectively. The magnetic fields may have the same or different polarities detectable by the position sensors. The position sensors may be coupled in parallel in the same or reverse directions to produce a combined sensor output. The circuitry may determine position information for the optics assembly and/or the image sensor based on the combined sensor output. The camera system may use the position information as a feedback signal to control the position of the optics assembly (e.g., for autofocus) and/or the position of the image sensor (e.g., for optical image stabilization (OIS)).
