Therefore, you shou ld p erform all analog ad ju stm ents p rior to any d igital ad ju stm ents. 1. Analog gain (the Gain (dB) or Calibrate Gain Target p aram eters in the Analog Controls set) is m u ltip lied by the analog signal to increase the signal strength before the A/ D conversion. It is u sed to take ad vantage of the fu ll d ynam ic range of the A/ D converter. For exam p le, in a low light situ ation the brightest p art of the im age m ay be consistently com ing in at only 50% of the DN . An analog gain of 6 d B (2x) w ill ensu re fu ll u se of the d ynam ic range of the A/ D conv erter. Of cou rse the noise is also increased . 2. The analog offset or black level (Black Level (D N ) com m and ) is an ―artificial‖ offset introd u ced into the vid eo p ath to ensu re that the A/ D is fu nctioning p rop erly. The analog offset shou ld be set so that it is at least 3 tim es the rm s noise valu e at the cu rrent gain. Digital Processing To op tim ize cam era p erform ance, d igital signal p rocessing shou ld be com p leted after any analog ad ju stm ents. 1. Fixed p attern noise (FPN ) calibration (calcu lated u sing the Calibrate FPN p aram eter) is u sed to su btract aw ay ind ivid u al p ixel d ark cu rrent. 2. The d igital offset (D igital Offset (D N ) p aram eter) enables the su btraction of the ―artificial‖ A/ D offset (the analog offset) so that ap p lication of the PRN U coefficient d oes not resu lt in artifacts at low light levels d u e to the offset valu e. You m ay w ant to set the D igital Offset (D N ) valu e if you are not u sing FPN correction bu t w ant to p erform PRN U correction. 3. Photo-Resp onse N on-Uniform ity (PRN U) coefficients (calcu lated u sing the PRN U Target and Calibrate PRN U, or PRN U Calibration Algorithm Selector p aram eters in the D ata Processing fam ily) are u sed to correct the d ifference in resp onsivity of ind ivid u al p ixels (i.e. given the sam e am ou nt of light d ifferen t p ixels w ill charge u p at d ifferent rates) and the change in light intensity across the im age either becau se of the light sou rce or d u e to op tical aberrations (e.g. there m ay be m ore light in the center of the im age). PRN U coefficients are m u ltip liers and are d efined to be of a valu e greater than or equ al to 1. This ensu res that all p ixels w ill satu rate together. 4. Backgrou nd su btract (Background Subtract (D N ) p aram eter) and system (d igital) gain (D igital Gain (D N ) p aram eter) are u sed to increase im age contrast after FPN and PRN U calibration. It is u sefu l for system s that p rocess 8-bit d ata bu t w ant to take ad vantage of the cam era’s 12 bit d igital p rocessing chain. For exam p le, if you find that you r im age is consistently betw een 128 and 255DN (8 bit), you can su btract off 128 (Background Subtract (D N ) 2048) and then m u ltip ly by 2 (D igital Gain (D N ) 8192) to get an ou tp u t range from 0 to 255. 03-032-20123-01 Teledyne DALSA Spyder3 GigE Vision SG-14 Monochrome Cameras User’s Manual 47 Analog Gain and Offset Adjustment Op tim izing offset p erform ance and gain in the analog d om ain allow s you to achieve a better signal-tonoise ratio (d ynam ic range).

Resu lts of the FPN correction are u sed in the PRN U p roced u re. We recom m end that you rep eat the correction w hen a tem p eratu re change greater than 10°C occu rs or if you change the analog gain, integration tim e, or line rate. PRN U correction requ ires a clean, w hite reference. The qu ality of this reference is i m p ortant for p rop er calibration. White p ap er is often not su fficient becau se the grain in the w hite p ap er w ill d istort the correction. White p lastic or w hite ceram ic w ill lead to better balancing.

Becau se m ost of the other blocks in the PLC u se p reconfigu red inp u ts and ou tp u ts, the Signal Rou ting Block is the p rim ary m ethod of rou ting a signal from one block to another. How the Signal Routing Block Works The Signal Routing Block has 8 outputs (I0 - I7). Each output uses a 16:1 multiplexer that connects to 16 inputs. The Signal Routing Block has more than 16 input signals, so not every input can be connected to every one of signals I0 - I7. However, signals I0 - I7 are functionally identical, so connecting to a specific one isn’t important. If you can’t route the input with your first choice, simply choose another. The Lookup Table lets you connect any input signal I0-I7 to any Lookup Table output signal Q0-Q17 03-032-20123-01 Teledyne DALSA Spyder3 GigE Vision SG-14 Monochrome Cameras User’s Manual 91 You can manipulate your inputs using simple or complex Boolean expressions. The following expressions are both valid: Q0 = I6 Q6 = !(I4 & I6) & ((I2 ^ I5) | I1) Teledyne DALSA 03-032-20123-01 92 Spyder3 GigE Vision SG-14 Monochrome Cameras User’s Manual Syntax Line Ou tp u t Inp u t Exp ression Com bined Exp ression Boolean Op erators Correct Lookup Table Syntax Valid Construction Ou tp u t = Exp ression EOL (end of line) Q0, Q1, Q2, ..., Q16, Q17 I0, I1, I2, ..., I6, I7 Inp u t N ot Inp u t Boolean constant Exp ression Boolean op erator Exp ression N ot & (and ) | (or) ^ (xor) !

Thu s, the ou tp u ts have a total nu m ber of 256 inp u t com binations. The resu lt of each com bination can be 1 or 0. When you m od ify the equ ations in the Looku p Table, the controller calcu lates the resu lts of all 256 inp u t com binations and stores the resu lt of each ou tp u t as a 256-bit looku p table (hence the nam e). There are 18 ou tp u ts (Q0 - Q17), so the controller calcu lates 18 d ifferent looku p tables. The controller then p asses the resu lting 18 looku p tables to the IP Engine. Know ing the valu e of the 8 inp u ts, the PLC need s only look u p the valu e of the resu lting ou tp u t (for each ou tp u t), rather than calcu late it. Thu s, the Looku p Table can achieve a p rop agation d elay of only one system clock cycle (30 ns), regard less of the com p lexity or nu m ber of Boolean exp ressions.
