Features AW00123409000202 Basler ace USB 3.07.5 Digital ShiftFor information about the availability of digital shift on a specific camera model, see Table 41 onpage 191 and Table 42 on page 192.The digital shift feature lets you change the groups of bits that are output from the ADCs in thecamera. Using the digital shift feature will effectively multiply the output of the camera by 2 times, 4times, 8 times, or 16 times. The next two sections describe how the digital shift feature works whenthe camera is set for a 12 bit pixel format and when it is set for a 8 bit pixel format. There is also asection describing precautions that you must observe when using the digital shift feature and asection that describes enabling and setting the digital shift feature.7.5.1 Digital Shift with 12 Bit Pixel FormatsNo ShiftAs mentioned in the Functional Description section ofthis manual, the camera uses 12 bit ADCs to digitizethe output from the imaging sensor. When the camerais set for a pixel format that outputs pixel data at 12 biteffective depth, by default, the camera transmits the12 bits that are output from the ADC.Shift by 1When the camera is set to shift by 1, the output fromthe camera will include bit 10 through bit 0 from theADC along with a zero as an LSB.The result of shifting once is that the output of thecamera is effectively multiplied by 2. For example,assume that the camera is set for no shift, that it isviewing a uniform white target, and that under theseconditions the reading for the brightest pixel is 100.If you changed the digital shift setting to shift by 1,the reading would increase to 200.If the digital shift feature is not available for your camera you can use the gainfeature to obtain an effect similar to adjusting digital shift.For more information about the gain feature, see Section 7.2 on page 193.ADCNo ShiftMSBLSBbit0bit1bit2bit3bit4bit5bit6bit7bit8bit9bit10bit11ADCShifted OnceMSBLSBbit0bit1bit2bit3bit4bit5bit6bit7bit8bit9bit10bit11 "0"
