7.6. Special mode setting

In this chapter, the user will find the register setting tables for using special modes. Detailed descriptions are given in the corresponding

chapters of these modes; see chapter 5.7., Pixel-field.

7.6.1. TOF dual DCS acquisition with phase-shifted integration time (motion blur reduction)

■ This mode needs the following basic setting of the MT registers:

MT_0_hi = 0x34, MT_1_hi = 0x3E.

■ Reset the MT registers to the default values after leaving this mode:

MT_0_hi = 0x30, MT_1_hi = 0x35.

--- 1

Table 35: Basic measurement mode setting

Notes:

Setting is not applicable for this application.

Output is effectively 4x DCS in 2 DCS-frames.

7.6.2. TOF and grayscale single DCS acquisition with 2 different integration times (High dynamic range)

Notes:

Output is effectively 2 DCS frames with different integration times in each 1 readout frame.

Grayscale image passively illuminated by ambient-light only.

Grayscale image passively illuminated by ambient-light and actively illuminated by modulated LED/LD.

Note: LED driver is always turned on. Take care that the LED driver and the epc635 chip does not exceed the maximum operating limits.
