Abstract: Systems, apparatuses, and methods for estimating object distance with camera lens focus calibration are disclosed. A relationship between in-focus lens position and object distance is captured in a calibration phase for a plurality of object distances and lens positions for a given camera. The in-focus lens positions and corresponding object distances are stored as calibration data in a memory device of the given camera. Next, during operation of the given camera, a control circuit receives the in-focus lens position that was used to capture a given image. Then, the control circuit performs a lookup of the calibration data with the in-focus lens position to retrieve a corresponding object distance. Next, the corresponding object distance is used as an estimate of a distance to an object in the scene captured in the given image by the given camera.
