Dynamic Range Control (Multi-Slope Mode)

By setting the

“ExposureMode” register to “Multi Slope”, it is possible to change the

slope of the photoelectric conversion curve at multiple points in order to increase the

dynamic range of captured images. In this mode, the registers

“MultiSlope_Level1, 2, 3”

set the knee point levels of the linear response, and

“MultiSlope_Timing 1, 2, 3” set the

integration time of each slope. The greater the integration time ratio, the more the

dynamic range is extended; however the minimum value should not be less than 1.



This function only operates in Exposure Mode

“Multi Slope” (5.3.4). This function

cannot be used in

“Free Run” mode or external trigger modes (“External egde”,

“External level”).



The scan cycle becomes longer than normal

7.1

MultiSlope Mode Default Setting Operation

Let us take as an example 5 levels of light intensity (Strong: A ~ Weak: E). The 5

coloured lines/dots labeled intensity A~E illustrate light entering the camera during the

exposure time period set by

“ExposureTimeCounter”.

The default settings are as follows:

MultiSlope_Timing1: 0, MultiSlope_Timing2: 1, MultiSlope_Timing3: 10

MultiSlope_Level1: 0, MultiSlope_Level2: 5, MultiSlope_Level3: 10

ExposureTimeCounter: 61

Exposure starts at exposure time 0

At exposure time 50, the signal is reset to 1/3 of the saturation level. “Reset”
means that any signal above the set value (in this case 1/3 of the saturation level)

is discarded. With this first reset, the portions of signals A-C which exceed the 1/3

saturation level are discarded, but D-E are unaffected.

With a further exposure time of 10 (from 50 to 60), the signal is reset a second

time to 2/3 of the saturation level. With this second reset, the portion of signal A

which exceeds the 2/3 saturation level is discarded. There is no effect on B-E

from this reset.

Exposure stops at exposure time 61.

*Actual settings & exposure times may vary depending on the camera model being used
