Abstract: An example method for camera processing includes detecting a first region of interest for image content captured with a primary camera, detecting a second region of interest for image content captured with a secondary camera, comparing the first region of interest and the second region of interest, determining a first lens position for a secondary camera lens of the secondary camera based on an autofocus process for the secondary camera, determining a second lens position for the secondary camera lens of the secondary camera based on a determined lens position for a primary camera lens of the primary camera, determining a lens position for the secondary camera lens based on the first lens position or the second lens position based at least in part on the comparison, and causing the secondary camera to capture images with the secondary camera lens at the determined lens position.

Abstract: An on-chip resistor correction circuit includes a first MOS transistor connected between VDD and a reference resistor, the other end of the reference resistor being grounded; an operational amplifier for outputting a first control signal based on a reference voltage and a voltage of the reference resistor; a second MOS transistor connected between VDD and a reference node; a branch where each of the on-chip resistors is located is controllably connected between the reference node and ground; a comparator for generating a comparison signal based on the voltage of the reference node and the reference voltage; and a controller for generating a control signal under the action of the comparison signal to control the branch where each of the on-chip resistors is located to turn on or off.
