1. A method of operating an apparatus, the method comprising: alternating between reading out a row of pixel values from a top portion of a first sensor and a row of pixel values from a bottom portion of the first sensor; reading out a row of pixel values from a second sensor in parallel with the reading out of the row of pixel values from the top portion of the first sensor, wherein reading out said row of pixel values from a second sensor in parallel with the reading out of the row of pixel values from the top portion of the first sensor is performed during a first read out time period, said row of pixel values read out from the first sensor during the first read out time period corresponding to a scene area which overlaps a scene area to which said row of pixel values read out from the second sensor corresponds; reading out during said first read out time period a row of pixel values from a third sensor capturing a scene area below the scene area to which said row of pixel values read out from the second sensor correspond; during a second read out time period reading out an additional row of pixel values from the third sensor in parallel with reading out of a row of pixel values from the bottom portion of the first sensor, said row of pixel values from the bottom portion of the first sensor corresponding to a scene area which overlaps the scene area captured by the additional row of pixel values from the third sensor; and during said second read out time period reading out an additional row of pixel values from the second sensor.
