This disclosure describes techniques to compensate for changes in a depth of field of a camera caused by changes in orientation of the camera (e.g., tilt) and changes in the temperature of the camera. For instance, the described techniques may utilize an actuator, such as a voice-coil motor, of the camera to adjust an image distance of the camera lens to compensate for changes in the depth of field of the camera caused by changes in the orientation of the camera and/or changes in temperature of the camera. One or more models may be generated using calibrated input current values for the voice-coil motor which indicate, for various changes in orientation and temperature of the camera, input current values to cause the voice-coil motor to adjust the image distance of the camera to maintain the desired depth of field.
