From b5e587dc08e470d05a29039159d7deaec820a0d9 Mon Sep 17 00:00:00 2001 From: Mike Rosseel Date: Fri, 26 Dec 2025 21:00:54 +0100 Subject: [PATCH 01/16] Fix 16-bit image saturation detection in auto exposure MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The histogram zero-star handler was using a hardcoded saturation threshold of 250 ADU, which only works for 8-bit images (0-255). For 16-bit images (0-65535), this incorrectly flagged nearly all pixels as saturated. Changes: - Detect image bit depth by checking max pixel value - Use 64000 threshold for 16-bit images (98% of 65535) - Use 250 threshold for 8-bit images (98% of 255) - Add saturation_threshold to metrics for debugging This fixes histogram analysis when processing 16-bit raw sensor data, though currently auto exposure only receives 8-bit processed images. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 --- python/PiFinder/auto_exposure.py | 13 ++++++++++++- 1 file changed, 12 insertions(+), 1 deletion(-) diff --git a/python/PiFinder/auto_exposure.py b/python/PiFinder/auto_exposure.py index ea6d05af..f4b181a6 100644 --- a/python/PiFinder/auto_exposure.py +++ b/python/PiFinder/auto_exposure.py @@ -475,7 +475,17 @@ def _analyze_image_viability(self, image: Image.Image) -> tuple: # Calculate metrics mean = float(np.mean(img_array)) std = float(np.std(img_array)) - saturated = np.sum(img_array > 250) + + # Determine saturation threshold based on image bit depth + # 8-bit images: 0-255 range, saturate at ~250 (98% of max) + # 16-bit images: 0-65535 range, saturate at ~64000 (98% of max) + img_max = np.max(img_array) + if img_max > 1000: # Likely 16-bit (range 0-65535) + saturation_threshold = 64000 # 98% of 16-bit range + else: # 8-bit (range 0-255) + saturation_threshold = 250 # 98% of 8-bit range + + saturated = np.sum(img_array > saturation_threshold) saturation_pct = (saturated / img_array.size) * 100 # Viability criteria from test_find_min_exposure.py @@ -489,6 +499,7 @@ def _analyze_image_viability(self, image: Image.Image) -> tuple: "mean": mean, "std": std, "saturation_pct": saturation_pct, + "saturation_threshold": saturation_threshold, "has_signal": has_signal, "has_structure": has_structure, "not_saturated": not_saturated, From c9ae96919910e7c8649b3c711e3b44dbae8e9044 Mon Sep 17 00:00:00 2001 From: Mike Rosseel Date: Fri, 26 Dec 2025 21:01:20 +0100 Subject: [PATCH 02/16] Add exposure time and bit-depth displays to SQM view MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Enhanced the SQM view to show additional diagnostic information: - Current camera exposure time (top right): "400ms" or "0.4s" - 8-bit processed SQM value (right side, labeled "8bit") - 16-bit raw sensor SQM value (left side, labeled "16bit") when available The 8-bit and 16-bit values are positioned to not overlap, with the 8-bit value keeping its original position from when it was labeled "raw".
