must be entered in register PROFILE_INT3 for the single integration slope mode; the other registers are to be filled with zeros.
The following conditions must be met to display a sensor frame as a live image:
∙No integration time value must be lower than:
PROFILE_INTX >= 4000 * (40.106 / PROFILE_PIXELCLK)
∙Additionally, no integration time except the last may be lower than: PROFILE_INTX > 4000 * (3.52.1012 / PROFILE_PIXELCLK)
in the multiple integration slope mode.
Example: w $138 #24000000 ;single int. SMode with 24msPROFILE_SHUTTER The register specifies the sensor shutter principle. Please note the multiple integration slope mode is not possible when selecting the rolling shutter and, thus, registers PROFILE_INT0, PROFILE_INT1, PROFILE_INT2 and PROFILE_INT3 are inactive. The integration time is here determined by the image readout rate.
Example: | w $148 #1 | ;rolling shutter mode |
PROFILE_SUBSAMPLE
The register specifies whether or not a subsampling of the lines and/or columns of the sensor shall be carried out.
Example: | w $149 #3 | ;X/Y Subsampling |
PROFILE_AMLIFIER The register specifies the amplification factor of the analog amplifier downstream of the sensor. The register value should not be changed for the following reasons:
∙The proper calibration of the camera is no longer guaranteed.
∙The pixel values are falsified through the amplification limitation.
∙The signal noise would be amplified and the desired improvement of the image brightness cannot be achieved.
| Example: | w $14A #1 | ;Ampl.factor is 5.25 |
PROFILE_CALIB | The register specifies the calibration routine for the sensor. | ||
| The output amplifier is calibrated during every line blanking period. The fast | ||
| mode (#0) can force a calibration to be carried out during one clock cycle. This | ||
| is, however, not as accurate as would be desired, and thermal noise would be | ||
| unavoidable during calibration; in contrast thereto, the slow calibration mode | ||
| (#1...#3) is incremental and free of any thermal noise. Some 200 or more | ||
| "slow" calibrations have the same effect as one "fast" calibration. The differing | ||
| "slow" calibration modes may be set at the start of an image (#1) or any line | ||
| not yet read out (#2) or both together (#3). | ||
| Example: | w $14B #1 | ;slow image calibration |
PROFILE_PRECHARGE
The register is set either to
In some applications, it may be necessary to use the continuous charging of the pixel columns instead of the precharging with every line scanning operation.
