Sequence of Control Voltages at the HDR Gate
Sequence of Voltages in a Piecewise Linear Pixel Response
The exposure indicator is controlled by:
• R0x1B LED_OUT Control
The MT9V022 provides an output pin, LED_OUT, to indicate when the exposure takes
place. When R0x1B bit 0 is clear, LED_OUT is HIGH during exposure. By using R0x1B, bit
1, the polarity of the LED_OUT pin can be inverted.
High dynamic range is controlled by:
• R0x08 Shutter Width 1
• R0x09 Shutter Width 2
• R0x0A Shutter Width Control
• R0x31
In the MT9V022, high dynamic range (that is, R0x0F, bit 6 = 1) is achieved by controlling
the saturation level of the pixel (HDR or high dynamic range gate) during the exposure
period. The sequence of the control voltages at the HDR gate is shown in Figure 21. After
the pixels are reset, the step voltage, V_Step, which is applied to HDR gate, is setup at V1
for integration time t
V4, which also serves as an antiblooming voltage for the photodetector. This sequence of
voltages leads to a piecewise linear pixel response, illustrated (in approximates) in
Figure 21 on page 26.
