Figure 17: Vertical and Horizontal binning of two rows
Step 1 Charge is built up on the sensor.
Step 2 Charge in the frame is shifted vertically by one row, so that the bottom row of charge moves down into the
shift register.
Step 3
Charge in the frame is shifted vertically by a further row, so that the next row of charge moves down into the
shift register, which now contains charge from two rows - i.e. the charge is vertically binned.
Step 4
Charge in the shift register is moved horizontally (through the EM Gain register, if using the EM output
amplier) until the charge from the rst data pixel is just about to enter the output node of the amplier.
Step 5 Charge in the shift / EM Gain register is moved horizontally by one pixel, so that charge on the endmost
pixel of the shift register is transferred into the output node of the amplier.
Step 6
Charge in the shift register is again moved horizontally, so that the output node of the amplier now contains
charge from two pixels of the shift register - i.e. the charge has been horizontally binned.
Step 7
The charge in the output node of the amplier is passed to the analog-to-digital converter for each row and
is read out.
Step 8 Steps 5 - 7 are repeated until the shift register is empty. The process is repeated from Step 2 until the whole
frame is read out.
