Abstract

Methods are disclosed for digital cameras to gain tilt information of an image sensor of the camera in order to achieve a fast correction for this tilt. By moving the lens of the camera to positions providing a maximum sharpness of at least three regions of interest (ROI) in the image sensor the tilt of the image sensor is calculated by using the correspondent lens/sensor distances and the distances of the different ROIs to the center of the image sensor. Yaw and pitch values of the tilt of the image sensor are calculated to enable an alignment of the sensor.
