The pixels addressing is done by direct addressing of rows and columns. This
approach has the advantage of full flexibility when accessing the pixel array: multiple
windowing and sub-sampled read-out are possible by proper programming.
The following paragraphs clarify the timing for row- and column readout.
Figure 3 shows the timing of the line sequence control signals. The timing constraints
are given in table 5.
The address, presented at the address IO pins (A0…A9) is latched in with the LD-Y
pulse (active low). After latching; the external controller can already produce a new
address.
Latching in a Y-address selects the addressed row and connects the pixel outputs of
that row to the column amplifiers. Through the sequence of the S and R pulse and the
Reset pulse in-between the pixel output signal and reset level are sampled and
produced at the output of the column amplifier (to do the FPN double sampling
correction).
At this time horizontal read-out of the selected row can start and another row can be
reset to effectuate reduced integration time (electronic rolling shutter).
Table 5 shows the timing constraints for the horizontal or line-select timing.
