A method comprising: receiving a first set of frames corresponding to a scene captured by a color image sensor; and receiving a second set of frames corresponding to the scene captured by a panchromatic image sensor, wherein a number of frames in the second set is greater than a number of frames in the first set, characterized in that the method comprises generating color frames corresponding to the scene at a frame rate higher than a frame rate of the first set of frames based at least in part on processing of the first set of frames and the second set of frames; and aligning the second set of frames based on the first set of frames prior to generating the color frames, said aligning comprising: aligning (606, 608), in response to non-staggered exposure times associated with the color image sensor and the panchromatic image sensor, a frame at a timestamp in the second set to a frame at the corresponding timestamp in the first set or, if the frame at the corresponding timestamp is absent in the first set, to a frame in the first set at a timestamp preceding the timestamp of the frame in the second set; and/or aligning (606, 610), in response to staggered exposure times associated with the color image sensor and the panchromatic image sensor, a frame at a timestamp in the second set to at least one frame in the first set at a preceding timestamp and a succeeding timestamp of the timestamp of the frame in the second set. receiving a first set of frames corresponding to a scene captured by a color image sensor; and receiving a second set of frames corresponding to the scene captured by a panchromatic image sensor, wherein a number of frames in the second set is greater than a number of frames in the first set, characterized in that the method comprises generating color frames corresponding to the scene at a frame rate higher than a frame rate of the first set of frames based at least in part on processing of the first set of frames and the second set of frames; and aligning the second set of frames based on the first set of frames prior to generating the color frames, said aligning comprising: aligning (606, 608), in response to non-staggered exposure times associated with the color image sensor and the panchromatic image sensor, a frame at a timestamp in the second set to a frame at the corresponding timestamp in the first set or, if the frame at the corresponding timestamp is absent in the first set, to a frame in the first set at a timestamp preceding the timestamp of the frame in the second set; and/or aligning (606, 610), in response to staggered exposure times associated with the color image sensor and the panchromatic image sensor, a frame at a timestamp in the second set to at least one frame in the first set at a preceding timestamp and a succeeding timestamp of the timestamp of the frame in the second set. aligning (606, 608), in response to non-staggered exposure times associated with the color image sensor and the panchromatic image sensor, a frame at a timestamp in the second set to a frame at the corresponding timestamp in the first set or, if the frame at the corresponding timestamp is absent in the first set, to a frame in the first set at a timestamp preceding the timestamp of the frame in the second set; and/or aligning (606, 610), in response to staggered exposure times associated with the color image sensor and the panchromatic image sensor, a frame at a timestamp in the second set to at least one frame in the first set at a preceding timestamp and a succeeding timestamp of the timestamp of the frame in the second set.
