Page 11: Readout Modes
6.1.3. Readout Modes The Truesense Imaging sensors, employed in Baumer SXC cameras, are subdivided into four Taps. ◄ Figure 7 Taps of the employed sensors. Due to Baumer's integrated calibration technique, these taps are invisible within the re- corded images, but affect the operation and the rate of the readout process and therewith the readout time (t readout 6.1.3.1. Quad Mode On quad readout mode all four taps are read out simultaneously as displayed in the sub- sequent figure. ◄ Figure 8 Quad Tap Readout Mode. - Page 12 6.1.3.3. Single Mode In single readout mode all taps are combined as displayed in the subsequent figure. Figure 10 ► Single Tap Readout Mode. The data of all pixels of the sensor are moved to the output register and afterwards trans- fered to the memory. Once the information have left the output register, the readout is done. Due to the fact, that the complete sensor needs to be read out, the readout time t readout increased compared to quad and dual readout mode.

6.2.2. Trigger Mode After a specified external event (trigger) has occurred, image acquisition is started. De- pending on the interval of triggers used, the camera operates non-overlapped or over- lapped in this mode. With regard to timings in the trigger mode, the following basic formulas need to be taken into consideration: Case Formula earliestpossibletrigger(n+1) readout(n) exposure(n+1) - Page 15 6.2.2.2. Overlapped Operation: t > t exposure(n+2) exposure(n+1) If the exposure time (t ) is increased form the current acquisition to the next acquisi- exposure tion, the time the camera is unable to process occuring trigger signals (t ) is scaled notready down.

Page 23: Camera Functionalities
Camera Functionalities 8.1. Image Acquisition 8.1.1. Image Format A digital camera usually delivers image data in at least one format - the native resolution of the sensor. Baumer cameras are able to provide several image formats (depending on the type of camera). Compared with standard cameras, the image format on Baumer cameras not only in- cludes resolution, but a set of predefined parameter. These parameters are: ▪ Resolution (horizontal and vertical dimensions in pixels) ▪ Binning Mode (see chapter 4.1.7) Camera Type Monochrome SXC10 ■ ■ ■ ■ SXC20 ■... -

Page 27: Look-Up-Table
8.1.4. Look-Up-Table The Look-Up-Table (LUT) is employed on Baumer monochrome cameras. It contains 2 (4096) values for the available levels of gray. These values can be adjusted by the user. 8.1.5. Region of Interest (ROI) With the ROI function it is possible to predefine a so-called Region of Interest (ROI). This ROI is an area of pixels of the sensor. On image acquisition, only the information of these pixels is sent to the PC. Therefore all the lines of the sensor need not be read out, which decreases the readout time (t ). This increases the frame rate. readout This function is employed, when only a region of the field of view is of interest. It is coupled to a reduction in resolution. - Page 28 Pixel Information of Interrest Read out Lines Discarted Pixel Information Figure 21 ► Partial Scan: Read out Lines. The most significant reduction of the readout time – compared to a full frame readout in dual mode – can be achieved if the ROI is positioned as follows: ▪ within one of the sensor halves ▪ symmetrically spread to both sensor halves For example, the readout time of the ROI's in the figures 21 and 22 is the same. Figure 22 ► Partial Scan: Example ROI's with identical readout times. On asymmetrically spread ROI's, the readout time is affected by the bigger part of the ROI. An example for this fact is shown in the figure below: Figure 23 ► Partial Scan: Read out time linked with position of the ROI.

Page 29: Binning
On digital cameras, you can find several operations for progressing sensitivity. One of them is the so-called "Binning". Here, the charge carriers of neighboring pixels are aggre- gated. Thus, the progression is greatly increased by the amount of binned pixels. By using this operation, the progression in sensitivity is coupled to a reduction in resolution. Baumer cameras support three types of Binning - vertical, horizontal and bidirectional. In unidirectional binning, vertically or horizontally neighboring pixels are aggregated and reported to the software as one single "superpixel". In bidirectional binning, a square of neighboring pixels is aggregated. -
