Figure 41:

Programmable Multiple Slope Response

In the figure above, the red lines represent a pixel on which a large amount of light is falling. The blue

line represents a pixel on which less light is falling. As shown in the figure, the bright pixel is held to a

programmable voltage for a programmable time during the exposure time. This happens two times to

not saturate the pixel at the end of the exposure time. This does not influence the darker pixels, so

they will have a normal response. The VTGLOW voltages and different exposure times are

programmable using the sequencer registers. The VTGLOW programming controls the placement of

the knee points on the X-axis, while the programmed exposure times control the slope of the

segments. With both these features, you can achieve a response as seen in the figure below.
