v1.0.8
20251009
Important: We strongly recommend all users update to v1.0.8 immediately after receiving the device.
What’s New
1) Smart Compression for Document Photos
New codec tuned for paper/printed text.
Typical file size ~150 KB per image while maintaining text sharpness for OCR and reading.
Trade-off: Color fidelity is slightly less accurate than previous versions.
Benefit: Much faster uploads over the internet (better experience on slower or metered connections).
2) Enhanced Autofocus with Anti-Shake Filtering
New stabilized AF pipeline designed for handheld capture.
Filters minor hand tremor to preserve text clarity, reducing the blur seen in prior releases.
The advanced AF routine takes about ~4 seconds end-to-end (trigger → focus → anti-shake → save).
How to Capture the Sharpest Text (Recommended Use):
Keep ~20 cm (≈8 in) between the device and the document.
This distance helps the camera lock focus reliably on printed text.
If you must shoot closer than 20 cm, keep the device perfectly parallel to the page.
Tilting at close range reduces focus margin and can soften edges.
Audible focus lock cue: When focus is acquired, you may hear a crisp mechanical “click” from the lens module . This indicates the device has locked focus and is ready to capture.
Notes & Trade-offs
The compression update prioritizes legible text and smaller files over perfect color reproduction.
AF duration may vary slightly with lighting/contrast; ensure good, even lighting for best results.
