First image data and second image data are captured by a first image sensor and second image sensor(s), using at least two different settings. The first image data includes first subsampled image data of at least a first part of a first field of view of the first image sensor that has at least a part of overlapping field of view. The first image data and the second image data are processed together, using HDR imaging technique, to generate a first HDR image and a second HDR image. During processing, interpolation and demosaicking is performed on the first subsampled image data, by employing the second image data and using HDR imaging technique. Demosaicking is performed on the second image data, by employing the first image data and using HDR imaging technique.
