## 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.

### 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.

&#x20;

* 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.
