ABSTRACT:
The present invention describes methods and devices for reading out an image sensor with reduced delay times between the reading out of different lines. The method of a first embodiment reads out each line of an image sensor in at least two overlapping sequences, whereby each sequence comprises a succession of blanking times and pixel readout periods. The timing of the sequences is such that the readout periods of different sequences are interleaved. The method of a second embodiment provides a high-speed column readout by discharging a column bus by a load current modulated in amplitude and time. The method of a third embodiment provides a high-speed column readout by pre-charging a column bus by a load current provided by connecting the column bus to a DC potential. Devices corresponding to each of the methods are also provided.
