6 Image Sensor Register Information

Note : Register_num[ x : y ] means we want to access the y+1 th to x+1 th bits of Register_num . So Register 71[15 : 0] means that we want to access the 1st to 16th bit of the register number 71.

Register Overview

Register Name Register Address Default Value Description
Image_flipping 69[1:0] 0

The image coming out of the image sensor, can be flipped in X and/or Y direction. When flipping in Y is enable, the
bottom left pixel (0, 3071) is read out first instead of the top left one (0, 0). When flipping in X is enabled only the
pixels within a channel are flipped on the X-axis, not the channels themselves. Flipping in X is only supported when
using 32 channels per side .

0: No image flipping
1: Image flipping in X
2: Image flipping in Y
3: Image flipping in X and Y

Exp_ext 70[0] 0

The exposure time can be programmed in two ways, externally or internally. Externally, the exposure time is defined
as the time between the rising edge of T_EXP1 and the rising edge of FRAME_REQ .Internally, the exposure time is set by uploading the desired value to the corresponding sequencer register.

0: Exposure time is defined by the value uploaded in the
sequencer register (71-72)
1: Exposure time is defined by the pulses applied to the
T_EXP1 and FRAME_REQ pins

Exp_time 71-72[7:0]


(
Exp_time[15:0] = Reg 71[15:0]
Exp_time[23:16] = Reg 72[7:0]
)

1536

When the Exp_ext register is set to ‘0’, the value in this
register defines the exposure time according to the formula

Offset_bot 87[11:0] 780

A digital offset can be applied to the output signal. The value in this register defines the dark level offset
applied to the bottom(OUT1_N/P to OUT32_N/P) output signal (min = 0, max = 4095) More Info

Offset_top 88[11:0] 780

A digital offset can be applied to the output signal. The value in this register defines the dark level offset
applied to the top(OUT33_P/N to OUT64_P/N) output signal (min = 0, max = 4095) More Info

Number_lines_tot 1 3072

The value in this register defines the number of lines read
out by the sensor (min=1, max=3072)

PGA_gain 115[2:0] 0

0: unity gain
1: x2 gain
3: x3 gain
7: x4 gain

PGA_div 115[3] 0

1: divide the output signal by 3

ADC_range_mult 116[9:8] 1

Change the slope and the input range of the ramp used by the ADC More Info

0: 8 bit (x1)
1: 10bit (x2)
3: 12bit (x4)

ADC_range_mult2 100[1:0] 0

Extends the ADC range for slow input clock speeds. `ADC_range_mult`
has to be set to 3 for all bit modes when using this. More Info

0: x4
1: x8
3: x16

6.1 DaemonCLI

To set/get parameters from command line, DaemonCLI can be used:

Syntax: DaemonCLI <module> set/get <parameter> <value>

6.1.1 Predefined Commands

Certain Commands are available which allows the user to do certain tasks without explicitly setting the registers value.

Examples:

Analog Gain ( Register Info )

DaemonCLI image_sensor set analog_gain 2  // Set the image sensor analog gain to value "2"

This command is equivalent to :

DaemonCLI image_sensor set config_register 115 1  // Setting Gain (x2)
DaemonCLI image_sensor set config_register 116 0x3d5  // ADC_range fine-tuned for gain value
DaemonCLI image_sensor set config_register 100 1  //ADC_range_mult2
DaemonCLI image_sensor set config_register 87 2000 //Bottom channel output offset
DaemonCLI image_sensor set config_register 88 2000 //Top channel output offset

6.1.2 Setting and Getting Parameters Explicitly

With these commands we can set or get value of each register individually

Examples:

Number of Lines to be read ( Register Info )

DaemonCLI image_sensor get config_register 1 // get number of lines to be read


Image Flipping ( Register Info )

DaemonCLI image_sensor set config_register 69 2  //Flip image in Y direction


Setting Exposure Time ( Register Info )

DaemonCLI image_sensor set config_register 70 0 // Setting register to use internal exposure mode
DaemonCLI image_sensor set config_register 71 1536 
DaemonCLI image_sensor set config_register 72 0 


Digital Offset Bottom ( Register Info )

DaemonCLI image_sensor set config_register 87 1824


Digital Offset Top ( Register Info )

DaemonCLI image_sensor set config_register 88 1824

7.1 Camera Structure

“The hardware design of the AXIOM Beta was kept simple at first, purely addressing problems discovered with the AXIOM Alpha. In the beginning we had intended to design the camera around a single board on top of an off-the-shelf FPGA/system-on-chip development board: the MicroZed™, but as a result of field testing and together with feedback gathered from the community we agreed to make it far more powerful by devising a more complex stack of boards where each layer is dedicated to specific functions.” - Sebastian Pichelhofer.


Note: All layouts/dimensions have been laid-out in accordance with the specific requirements of this application. Reconfiguration is possible and encouraged. For guidance, contribution or commissions please contact us.


ABDK 2xHDMI.jpg


7.2 Camera Versions

Distinctions between AXIOM Beta's Developer Kit, Compact and Extended versions are purely denoted by variations in the camera's enclosure (or lack thereof). Aside from custom orders, e.g. where specific PCBs or modules aren't necessarily required, all internal PCB's and components are exactly the same.


Note: If a custom version of AXIOM Beta Developer Kit is required for scientific/research purposes, then it could be possible to make the necessary changes. Please make contact to discuss requirements.


7.2.1 AXIOM Beta Developer Kit

A skeleton frame provides support for the electronics, lens mount (e-mount) and tripod footplate. No surrounding enclosure allows for easy access to the AXIOM Beta's core components and their connectors.

Intended for developers and early adopters - currently shipping. See Prices.

Implications:

  • Skeleton enclosure only (3D View).
  • CMV12000 image sensor.
  • Camera control via connected PC and Linux Terminal/Console only.
  • Passive sensor cooling (works well).
  • Passive E-Mount (passive Canon / Nikon adapter available).
  • Screw-on UV/IR cut off filter instead of camera internal one.
  • Interface Board limits image sensors throughput to 150FPS@4K (faster Interface Board replacement will be available later).
  • Dual 5V 3+A AC power supply (included).
  • 1x HDMI 1080p60 output module and PMOD debug module are the only plugin modules available currently (AXIOM Beta has two slots).
  • Solder-on area on AXIOM Main Board not populated with gyroscopes/magnetometer/accelerator yet (will be available later on).
  • Power Board requires manual reconfiguration (trimmers) when switching to a different image sensor module (potentially in the future).
  • No power-on switch on camera yet (camera turns on when power is connected).
  • Cameras need to be user calibrated -> Factory Calibration.
  • Software/Firmware is a work in progress.

7.2.2 AXIOM Beta Compact (AB CP)

This enclosure option provides a solid but lightweight aluminum layer around the camera's electronics and incorporates several mount points and future expansion slots. Great for rig integration or general in-the-field protection. More camera control and recording options are meant to be ready together with the AXIOM Beta compact.


Note: This enclosure version is currently in development.

7.2.3 AXIOM Beta Extended (AB EX)

With the Extended enclosure the AXIOM Beta shall resemble the golden age of film cameras. With ergonomics in mind and space for an integrated recording device (AXIOM Recorder), this enclosure is intended to be ideal for shoulder mounted operation.


Note: This version of enclosure is in concept phase.

7.4 Enclosures

There are several AXIOM Beta enclosure variants, some are finished and available and some are still in development. The AXIOM Beta Developer Kit (ABDK) has a skeleton framework instead of an enclosure allowing easy access to the electronics but at the same time providing a strong and solid link between hardware, lens mount and tripod mount base. This is great for developers and in lab conditions but there are several other variants that add a 3d printed, laser cut acrylic shell around this skeleton framework. There is also the Compact enclosure as very solid custom CNC milled aluminium multi part assembly.

7.6 Main PCBs in Detail

AXIOM Beta electronic board stack.

The AXIOM Beta comprises five core printed circuit boards (PCBs):

  • Sensor Board
  • Sensor Interface Board
  • AXIOM Beta Main Board
  • AXIOM Beta Power Board
  • Microzed

Different plugin modules and shields can be used to add interfaces or extend functionality.

In rare cases users may want to build the camera and or its components themselves - see AXIOM_Beta/Prices for cost estimates. We can either supply all the individual components or the relevant files with a view to a user sourcing unpopulated PCBs directly from the manufacturer. In any event make contact and we'll provide guidance.

The Beta CMV12K ZIF Sensor Board hosts the heart of every cinema camera - the (CMOS) image sensor. apertus° offered three different sensor options during the crowd funding campaign; Super35, Super16 and 4/3rds, and as almost 90% of the backers opted for the Super35 sensor its respective module was developed first. The camera uses the ams Sensors Belgium CMV12000. Note: The ZIF (Zero insertion force) socket is useful for developers as it allows for the sensors removal at the turn of a lever (zero force). The AXIOM Beta Compact camera hosts the Beta CMV12K THT Sensor Board. THT (Through hole tech) is suited to applications where the sensor-front-end won't be removed regularly.
Interface Board
Interface Board V1 without FPGA for now
The Beta Interface Dummy Board acts as a bridge between the image sensor board and the rest of the camera. It converts communication between the aforementioned components to a standard protocol so that almost any image sensor that becomes available in the future can be used with the AXIOM Beta without changing the rest of the hardware. If AXIOM users felt that 8K was in demand they would simply swap the sensor board for one capable of capturing images in the desired resolution.
Beta Main Board
AXIOM Beta Main Board circa 2016.
The Beta Main Board is the equivalent of a PC's motherboard. It hosts two external medium-speed shield connectors and two high-speed plugin module slot connectors. These act as a central switch for defining where data captured by the sensor and other interfaces gets routed to inside the hardware. In this regard, all specifics can be dynamically reconfigured in software opening up a lot of new possibilities such as adding shields for audio recording, genlock, timecode, remote control protocols or integrating new codecs and image processing inside the FPGA. In the centre of the main board a 'solder-on' area has been incorporated, this will for example host chips capable of sensing the camera's orientation and acceleration (the same chips used to stabilise quadcopters and track head movements in VR headsets). Being situated directly behind the image sensor centre means that these sensors are ideally positioned to supply data for image stabilisation or metadata about the camera’s orientation and movement during a shot.
CSO

The AXIOM Beta CSO (Center Solder On) is a small addon PCB that can be added to a pre-designated area on the Beta Main Board. It hosts chips capable of measuring and controlling compensation processes via the camera's software, i.e. for orientation and acceleration (the same chips used to stabilise quadcopters and track movement in VR headsets), magnetic field related data, and three dimensional motion sensing.

Beta Power Board
AXIOM Beta Power Board V.01.

The Beta Power Board PCB generates all the different supply voltages for the chips and logic on the other PCB’s inside the camera. It also monitors currents so that it can estimate remaining power based on the recorded consumption. In the current revision of the camera a predefined set of supply voltages matching the current application with the rest of the camera have been generated, in the future however, it will be possible for users to dynamically reconfigure voltages according to their needs through the camera’s software.

7.7 Shields and Plugin Modules

1xHDMI Module.

The AXIOM Beta has two high speed module slots with PCIe connectors (these are not really PCIe cards, we just utilize PCIe for the connectors). Each module has a total bandwidth to/from the main processing FPGA of at least 6 Gbit/s. This makes the modules perfect for dealing with high bandwidth video outputs like HDMI/Displayport/SDI.

Due to the flexibility that this arrangement provides this could also allow us to create a dedicated solid-state media recorder module in the future. For now the AXIOM Beta relies on external recording though.



7.7.1 Shields

The name shields was inspired by the Arduino plugin boards that are also called "shields". AXIOM Beta sports two shield slots with space for connectors going to both sides of the camera. In contrast to modules the shields in the Beta have slow and medium speed interfaces to the main processing FPGA, and, therefore, are perfect for tasks like: trigger IN/OUT, genlock IN/OUT, timecode IN/OUT, sync IN/OUT or connecting external sensors or buttons, LCDs, etc.

The AXIOM Beta has 2 medium speed IO interfaces to be used in conjunction with "shields".

  • One 200Mbit/s (west) shield interface.
  • One 1Gbit/s (east) shield interface.

Note: Shields are not hot plug-able.

    • 500MBit/s GPIO
  • Two modules can be combined in one 12.4 Gbit/s double height module.
  • Hot pluggable.

The plugin modules are PCIe x1 connectors which are not using PCIe signaling. The bottom Plugin Module is called "south" while the top is called "north".

7.8 Functions

Recording Options

AXIOM Beta Developer Kit.

The AXIOM Beta currently utilizes external third-party recorders for capturing moving images. A number of different products from different brands can record the HDMI signal from the AXIOM Beta and store the video in Prores or DNxHD. There are plans for enabling AXIOM Beta internal recording to solid state storage in the future however. In particular this is a requirement for writing high speed video as the Beta sensor is capable of capturing moving images at up to 300 FPS in full 4K resolution.


Operating System

Since the camera is running Linux, you have a full operating system at your disposal. This means any 3rd party peripherals like USB drives or wireless adapters should work out of the box. Standard protocols like SSH/FTP/SCP/etc. as well as Graphical User Interfaces via HTTP can be used to interface with the camera from computers and most mobile devices.


Sound

AXIOM Beta is not capable of recording sound internally at the moment.
