An image-stitching method compensates electronic rolling shutter (ERS) distortion and parallax to produce a composite image. A first and second image from respective sensors are received. An ERS correction mapping is computed at a lower resolution than a parallax correction mapping. A far point and a near point defining an initial epipolar line are identified. A compensated near point is determined from ERS data, and a compensated epipolar line is formed by linear interpolation between the far point and the compensated near point. A one-dimensional search along the compensated epipolar line yields a parallax translation between the images. A warp mapping is determined from the parallax translation and the ERS correction mapping, and applied to blend the images into a composite. The technique decouples ERS estimation from parallax and is suitable for multi-sensor capture devices and post-capture stitching.
