2-Quick Start For Raspberry PI

Step1,downlod json file for imx290/imx426/imx327 sensor module

• git clone https://github.com/INNO-MAKER/CAM-IMX462Mono.git

• cd /home/pi/CAM-IMX462Mono

• sudo chmod -R a+rwx *

Step2, Open the config.txt on Raspbian:

• sudo nano /boot/firmware/config.txt

Step3, Add the following text below the [all] line in the config.txt file

For CAM0

• dtoverlay=imx290,clock-frequency=74250000,cam0

For CAM1

• dtoverlay=imx290,clock-frequency=74250000,cam1

Step4, change camera_auto_detect=1

• camera_auto_detect=0

Step5,reboot and use libcamera for preview

• sudo reboot

Step7,use libcamera for preview:

• libcamera-still -t 0 --tuning-file /home/pi/CAM-IMX462Mono/innomakerpi5_imx290.json

4-FAQ

1, Not works on PI3 with bullseys os

Reason: On Raspberry Pi 3 and earlier devices running Bullseye you need to Resolve Method: re-enable Glamor in order to make the X-Windows hardware accelerated preview window work.

Open terminal window

• sudo raspi-config

Choose

• Advanced Options

• Glamor

• Yes.

Finally quit raspi-config and let it reboot your Raspberry Pi.

2 Not works on Raspberry PI5/CM5 with lastest OS

Reason：lack of json file.

Resolve Method: Download json file from legacy os or from our github.

5- IMX327 IMX462 IMX290 Selection Guide:

Below is a comparison table of the Sony IMX290, IMX327, and IMX462 color sensors, combining common characteristics and differences in a single table for clarity.

G Sensitivity (digits)	5486	10741	10741
Frame Rate (fps)	Up to 120	Up to 60	Up to 120
Near-Infrared (NIR) Performance	Good	Better	Best
Cost	Lowest	Medium	Highest
HDR Support	BOL-HDR	Multiple Exposure/Digital HDR	HCG Mode/HDR
Other Features	Mature driver support	Anti-reflective coating version (IMX327LQR1, sensitivity 2519 mV, SNR1s 0.17 lux)	High Conversion Gain (HCG) mode, superior noise control

Explanation

• Common Characteristics (first 5 rows: Resolution, Sensor Size, Pixel Size, Technology, Pin Compatibility): All three sensors share identical resolution, sensor size, pixel size, STARVIS back-illuminated CMOS technology, and pin compatibility, making them interchangeable in hardware designs and suitable for low-light and near-infrared applications.

• Differences (last 5 rows: G Sensitivity, Frame Rate, NIR Performance, Cost, HDR Support, Other Features):

• • G Sensitivity: IMX327 and IMX462 (10741 digits) outperform IMX290 (5486 digits) in low-light conditions.

  • Frame Rate: IMX290 and IMX462 support up to 120 fps, ideal for dynamic scenes; IMX327 is limited to 60 fps, better for static scenes.

  • NIR Performance: IMX462 offers the best NIR sensitivity, followed by IMX327, with IMX290 being the least effective.

  • Cost: IMX290 is the most cost-effective, IMX327 is mid-range, and IMX462 is the most expensive.

  • HDR Support: IMX290 supports BOL-HDR; IMX327 supports multiple exposure/digital HDR; IMX462 includes HCG mode and HDR, with better noise control.

  • Other Features: IMX290 has well-established driver support; IMX327 offers an anti-reflective coating version; IMX462’s HCG mode enhances low-light noise performance.

Selection Guidance

• IMX290: Best for budget-conscious projects requiring high frame rates but with moderate low-light performance needs (e.g., indoor surveillance).

• IMX327: Suitable for static low-light scenes (e.g., night vision surveillance) with a balanced cost-performance ratio.

• IMX462: Ideal for high-end applications requiring superior low-light and NIR performance (e.g., agriculture, intelligent transportation), but at a higher cost.
