Page 9: Digitization Taps
Global shutter means that all pixels of the sensor are reset and afterwards exposed for a specified interval (t ). exposure For each pixel an adjacent storage circuit exists. Once the exposure time elapsed, the information of a pixel is transferred immediately to its circuit and read out from there. Due to the fact that photosensitive area gets "lost" by the implementation of the circuit area, the pixels are equipped with microlenses, which focus the light on the pixel. 6.2.4 Digitization Taps The Truesense sensors, employed in Baumer HXC cameras can be read out up to 16 channels in parallel. Notice More channels increase the speed (framerate), but the use of more channels produces a higher heat generation. Use only the maximum required number of channels! Notice Due to sensor characteristics in 12 bit mode only 2 or 4 channels are available.

Page 10: Timings
Timings Notice Overlapped mode can be switched off with setting the readout mode to sequential shut- ter instead of overlapped shutter. The image acquisition consists of two separate, successively processed components. Exposing the pixels on the photosensitive surface of the sensor is only the first part of the image acquisition. After completion of the first step, the pixels are read out. The exposure time (t ) can be adjusted by the user, however, the time needed for the exposure readout (t ) is given by the particular sensor, image format and configuration. readout Baumer HXC cameras can be operated with two modes, the Free Running Mode and the Trigger Mode. The cameras can be operated non-overlapped or overlapped.

6.3.2 Trigger Mode After a specified external event (trigger) has occurred, image acquisition is started. De- pending on the interval of triggers used, the camera may operate non-overlapped or over- lapped in this mode, when overlapped mode is enabled. 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) < t exposure readout + t notready(n+1) exposure(n) readout(n) exposure(n+1) earliestpossibletrigger(n+1) exposure(n) > t exposure readout notready(n+1) exposure(n) 6.3.2.1 Overlapped Operation: t exposure(n+2) exposure(n+1) In overlapped operation attention should be paid to the time interval where the camera is unable to process occuring trigger signals (t ).

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 (combining of neighboring pixels) ▪ Subsampling (not every pixel is read) Camera Type HXC20 ■ ■ ■ HXC40 ■... -

The three coordinates are displayed within the buffer in the order R, G, B. BGR: Here the color alignment mirrors RGB. YUV: Color model, which is used in the PAL TV standard and in image compression. In YUV, a high bandwidth luminance signal (Y: luma information) is transmitted together with two color difference signals with low bandwidth (U and V: chroma information). Thereby U represents the difference between blue and luminance (U = B - Y), V is the difference between red and luminance (V = R - Y). The third color, green, does not need to be transmitted, its value can be calculated from the other three values. YUV 4:4:4 Here each of the three components has the same sample rate. Therefore there is no subsampling here. YUV 4:2:2 The chroma components are sampled at half the sample rate. This reduces the necessary bandwidth to two-thirds (in relation to ...

Page 24: Exposure Time
8.1.3 Exposure Time On exposure of the sensor, the inclination of photons produces a charge separation on the semiconductors of the pixels. This results in a voltage difference, which is used for signal extraction. Figure 15 ► Incidence of light causes charge separation on the semiconductors of the sensor. The signal strength is influenced by the incoming amount of photons. It can be increased by increasing the exposure time (t exposure On Baumer HXC cameras, the exposure time can be set within the following ranges (step size 1μsec): Camera Type exposure exposure HXC20 / HXC20c 4 μsec 1 sec HXC40 / HXC40c 4 μsec 1 sec 8.1.4 PRNU / DSNU Correction (FPN - Fixed Pattern Noise) CMOS ... -

8.1.5 High Dynamic Range (HDR) Beside the standard linear response the sensor supports a special high dynamic range mode (HDR) called piecewise linear response. With this mode illuminated pixels that reach a certain programmable voltage level will be clipped. Darker pixels that do not reach this threshold remain unchanged. The clipping can be adjusted two times within a single exposure by configuring the respective time slices and clipping voltage levels. See the figure below for details. In this mode, the values for t , t , Pot and Pot can be edited. Expo0 Expo1 The value for t will be calculated automatically in the camera.

8.1.9 Binning / Subsampling Notice Binning and Subsampling are only available at monochrome cameras. Baumer HXC cameras support horizontal Binning. In binning, horizontally neighboring pixels are aggregated and reported to the software as one single "superpixel". When subsampling, only certain pixels are read out. (Subsampling 2x2 = every second pixel in every second line.) Binning Illustration Example without Figure 21 ► Full frame image, no binning of pixels.

Page 29: Brightness Correction (Binning Correction)
8.1.10 Brightness Correction (Binning Correction) The summation of pixel values may cause an overload. To prevent this, binning correction was introduced. Binninig Realization 2x1 binning takes place within the FPGA of the camera. The binning cor- rection is realized by averaging the pixel values instead of simply adding them. 8.2 Color Adjustment – White Balance This feature is available on all color cameras of the Baumer HXC series. White balance means independent adjustment of the three color channels, red, green and blue by employing of a correction factor for each channel. 8.2.1 User-specific Color Adjustment The user-specific color adjustment in Baumer color cameras facilitates adjustment of the correction factors for each color gain. This way, the user is able to adjust the amplifica- tion of each color channel exactly to his needs. The correction factors for the color gains range from 1.0 to 4.0. non-adjusted histogramm after histogramm user-specific color adjustment ◄ Figure 24 Examples of histo- gramms for a non- adjusted ... -

Due to this fact exposure times are limited. However, this causes low output signals from the camera and results in dark images. To solve this issue, the signals can be amplified by a user-defined gain factor within the camera. This gain factor is adjustable from 1.0 to 4.0. Notice Increasing the gain factor causes an increase of image noise and leads to missing codes at Mono12, if the gain factor > 1.0... -

Page 34: Shutter
8.5.4 Double Shutter This feature offers the possibility of capturing two images in a very short interval. Depend- ing on the application, this is performed in conjunction with a flash unit. Thereby the first exposure time (t ) is arbitrary and accompanied by the first flash. The second expo- exposure sure time must be equal to, or longer than the readout time (t ) of the sensor. Thus the readout pixels of the sensor are recepitve again shortly after the first exposure. In order to realize the second short exposure time without an overrun of the sensor, a second short flash must be employed, and any subsequent extraneous light prevented.
