A7-1: Depending on the suitability of the lens and quantity, it can be customized at our group factories.
Please email us at ca-qa@centuryarks.com.

Q7-2: Is it possible to purchase with the CA378-AOIS lens removed?

A7-2: We can't sell because we can't do the imaging test at the time of assembly.
However, if you may be able to perform an imaging test using a removable reference lens, please email us at ca-qa@centuryarks.com.

Q7-3: Is it possible to change the angle of view and focal length without modifying CA378-AOIS?

A7-3: I think that it can be changed a little with an external lens attachment, but it cannot be changed with the current camera module.

  • About Raspberry Pi

Q8-1: How to set up a quick Raspberry Pi environment?

A8-1: The procedure for using a Raspbian image with SSP library installed is as follows.
(1) Download the following image.
https://www.centuryarks.com/images/product/sensor/2018-11-13-raspbian-stretch-CA378-AOIS.zip
(2) Follow the Raspbian installation guide.
https://www.raspberrypi.org/documentation/installation/installing-images/README.md
For manual installation, refer to page 4 of the following procedure.
https://github.com/centuryarks/CA378-AOIS/tree/master/Raspi3

Q8-2: Is it possible to use an ISP because the frame rate is low on the Raspberry Pi?

A8-2: Unfortunately, this is Broadcom's proprietary (*1) and at this time, no user is allowed to access the ISP.
(*1) Indicates that the source code, specifications, standards, structure, etc. are not disclosed.
The specific company or organization has the right and its specific details are not disclosed.
However, ISP can be used for the TinkerBoard compatible I/F board set that will be released soon.
We plan to provide image quality adjustment files that have been ISP tuned as default.
Customization can be adjusted for a fee, so please contact ca-qa@centuryarks.com for details.

  • About Jetson

Q9-1: Does CA378-AOIS_JSX2_2L support MIPI 4Lane?

A9-1: No, only MIPI 2Lane is supported.

Q9-2: Can Jetson TX2 board set (CA378-AOIS_JSX2_2L) be used with Jetson Xavier?

A9-2:
[HARDWARE]
CA378-AOIS's Jetson TX1 / TX2 development kit [I / F Board for Jetson] can be connected because the connector to the Xavier main unit is the same.
However, in Xavier, there are places where the power supply voltage is partly different from TX2, and it is necessary to replace the regulator IC.
The approximate specifications for the connection between the Xavier specification and our CA378-AOIS I/F board are as follows.
Resolution and frame rate: 12M @ 30fps
MIPI 2Lane x 6 (Xavier itself can connect up to 8)
[SOFTWARE]
Development plans are under consideration. Please contact us if you have any requests.
*Depending on the customer's business plan, individual consultation is also available.
Please contact ca-qa@centuryarks.com.

Q9-3: Is image quality adjustment possible with Jetson?

A9-3: Although you cannot adjust the image quality by yourself or our company, here are the answers we received from NVIDIA.
NVIDIA answers are as follows:
Yes, if you care about the image quality you have to go through the tuning process.
BTW, you need camera scaling partner to help to go through this.
We can't release the tuning tool due to IP and other business agreement issue, however we have enable camera partner to provide the support for customers, please find their information from below page:

  • RegisterSetting

Q10-1: The IMX378 specification supports RAW/12/10/8 output image formats.
Can you provide documentation on register settings for each output format?
Is it possible to change the clock setting?

A10-1: Please contact ca-qa@centuryarks.com for NDA for register setting information specifications.
As for the clock system setting, there is a sensor manufacturer non-disclosure register as well as expert knowledge, so user setting is difficult.
The register setting information file for each mode* is available on the following site.
*For the list, see the link of on the right
https://github.com/centuryarks/Sample/tree/master/CA378-AOIS/RegisterSettings
We also accept requests for register setting information files for other modes, but it will take about 2 or 3 weeks to create, so please contact ca-qa@centuryarks.com with your desired mode.
