The cdisplay is the universal display component of the LC/RRC system. Both lens and camera data are numerically and graphically illustrated on the cdisplay's 3,8 TFT screen. Using the cdisplay, virtual depiction of lens information for any lens is possible, independent of whether the camera is being used. This lens data is:
- manually calibrated once, and then saved
- read through the ctag
(cdisplay extension necessary)
- provided directly from the lens
(e.g. Cooke S4/i)
Through activating cdisplay's easy to read touch screen all operation functions of the lens and camera can be controlled with the cdisplay . The following software programmes are accessible:
- lens information
- camera control
- motion control
- special functions
- cdisplay.ext
The cdisplay -extension is an add-on module for the cdisplay . This consists of:
- A reader module for writing to and reading data from the memory chip ( ctag )
- A radio module for an independent communication with the camin
- Space for a battery to enable independent operation
In stand alone configuration, the cdisplay-ext unit with its 3.8 screen, ctag reader/writer, wireless module and battery, weighs just 440g and remains operational for up to 4 hours as a multifunctional tool for displaying and controlling functions of diverse camera systems.
- ctag
ctag is a microchip that can be used to store individual lens information and stuck to the inside of the lens cap. Once this information has been read by cdisplay, the virtual depiction of lens information is clearly visible on cdisplay's 3.8 screen. This information is possible for all lenses .
- Functionality
On all film sets, many different passive components are simultaneously being used. The patented cmotion system simply saves and (if desired) performs a readout of the technical relevant data (e.g. lens scales) from these components through its transponder. Currently, this technology is only being used for lens and user-data. However, in the near future, the operation and display system currently being implemented by cmotion should also be possible with filters, batteries and much more.
- ctag programming
Every lens (from the oldest to the newest) can be integrated into the cmotion system. Through a simple manual calibration of each lens (approximately 20 minutes), you are able to store the individual information of the lens (including serial number) and write it onto its individual ctag . Each lens will require its own ctag , the cdisplay unit however, can store lens information for up to 1000 lenses. During setup calibration, cdisplay will compare each end stop of the lens and match it with those in its memory. An exact match will identify that specific lens. If more than one lens is found to have similar end stops, each possible lens will be displayed on the screen for manual selection.
- PC lens calibration
The camin is connected to the PC via a serial port. Control of the motors is now possible through the PC keyboard.
A USB-webcam then needs to be aligned to the respective calibration scale with the image visible on you PC monitor.
Then, every scale position for the motor will be driven by a key on the keyboard. Every motor position will then be saved to that key.
All the data can now be transferred from the PC to the ctag . The ctag is then attached inside the lens cap with all the lens information, and can be read by any cdisplay anywhere in the world. ctag is completely maintenance free and does not require a battery to store its information.
The information can now be identified and illustrated on the cdisplay (extension necessary). The ctag needs to be brought within 4cm of the cdisplay's transponder (or visa versa) in order for the data to be read. This is all done without contact and completed within 1 second.
Notice:
While prepping the equipment the necessary lenses should be saved to the cdisplay. Then, on the set, during the calibration process, the lenses should be automatically recognized by the system and displayed on the cdisplay .
