摘要： In an example embodiment, method, apparatus and computer program product are provided. The method includes accessing image capture parameters of a plurality of component cameras at a first time instant, where the image capture parameters for a respective component camera of the component cameras are determined based on a scene appearing in a field of view (FOV) of the respective component camera. At a second time instant, a change in appearance of one or more objects of the scene from a FOV of a first component camera to a FOV of a second component camera is determined. Upon determining the change of the appearance of the one or more objects at the second time instant, image capture parameters of the second component camera are set based on image capture parameters of the first component camera accessed at the first time instant.

The method includes facilitating capture of at least one image of a scene including a foreground object by at least one rolling shutter sensor. The at least one image includes a pattern in an image region of the foreground object comprising a series of alternate dark and bright pixel regions. The at least one image is captured by setting exposure time of the sensor as equal or less than a read-out time of a set of pixel rows of a plurality of pixel rows, and by facilitating a repeating sequence of ON and OFF of flash such that flash is ON while capturing the set of pixel rows, and OFF while capturing subsequent set of pixel rows.
