the 656x480 is the preview pipeline.

@videodoctor Can you call ipl getimepath 0 while recording?

You bet, @0dan0 ! Here's the output while recording, with the original stock D firmware:

In hist.c Type A-C these addresses are different (same as each other)
uint8_t *imagebase = (uint8_t *)0xa2730b70; //start of LRV //PREVIEW

I have fixed hist.c to use these new addresses. Although as the D units are crashing before this, so no rush to try that.

Thanks for the continued investigation, @0dan0 . I'll see if I can get hist.c working now---I did have it calling during preview (and I think capture), but with the imagebase pointing to the wrong address in Type D, that might be why I saw it crashing.

I continued my investigation of sensor and ipl commands, and had Claude.ai look at the dumps and info. I ran:

Code: 
> ipl getcapmaxrawinfo 0

IPL(0) max raw width = 1936 height = 1076 lineoffset = 536870672
IPL(0) max raw ImgBit = -1 ImgPix = -1
> ipl dumpbuf 0

And Claude.ai gave me the following summary:


📊 Buffer Analysis - Proof of Native Capture​


PathBuffer SizeExpected for ResolutionMatch?
IMEP10x00334200 = 3,359,232 bytes1728 × 1296 × 1.5 (YUV) = 3,359,232✅ EXACT
IMEP20x00097e00 = 622,080 bytes656 × 480 × 1.5 = 472,320(with padding)
SIE_RAW0x002fade0 = 3,140,064 bytes1936 × 1076 raw Bayer✓


✅ Confirmed: Type D Captures at Native 1728x1296 (? Suspect ?)​


The IMEP1 buffer size exactly matches 1728×1296 YUV. This proves:


  1. NOT upscaled - If upscaled from 656x480, the buffer would only need ~472KB, not 3.3MB
  2. Native high-res capture - The full 3.3MB buffer is being used for each frame
  3. Path 1 is the capture path - Path 2 (656x480) is just for LCD preview


🤔 Interesting Mystery​


SourceResolution
Sensor max1936 × 1076
IMEP1 output1728 × 1296

Height 1296 > 1076! This means some ISP interpolation is happening to achieve the 4:3 ratio. But the quality is still far superior to the old 656x480.

Thanks for the continued investigation, @0dan0 . I'll see if I can get hist.c working now---I did have it calling during preview (and I think capture), but with the imagebase pointing to the wrong address in Type D, that might be why I saw it crashing.

I continued my investigation of sensor and ipl commands, and had Claude.ai look at the dumps and info. I ran:

Code: 
> ipl getcapmaxrawinfo 0

IPL(0) max raw width = 1936 height = 1076 lineoffset = 536870672
IPL(0) max raw ImgBit = -1 ImgPix = -1
> ipl dumpbuf 0

And Claude.ai gave me the following summary:


📊 Buffer Analysis - Proof of Native Capture​


PathBuffer SizeExpected for ResolutionMatch?
IMEP10x00334200 = 3,359,232 bytes1728 × 1296 × 1.5 (YUV) = 3,359,232✅ EXACT
IMEP20x00097e00 = 622,080 bytes656 × 480 × 1.5 = 472,320(with padding)
SIE_RAW0x002fade0 = 3,140,064 bytes1936 × 1076 raw Bayer✓


✅ Confirmed: Type D Captures at Native 1728x1296 (? Suspect ?)​


The IMEP1 buffer size exactly matches 1728×1296 YUV. This proves:


  1. NOT upscaled - If upscaled from 656x480, the buffer would only need ~472KB, not 3.3MB
  2. Native high-res capture - The full 3.3MB buffer is being used for each frame
  3. Path 1 is the capture path - Path 2 (656x480) is just for LCD preview


🤔 Interesting Mystery​


SourceResolution
Sensor max1936 × 1076
IMEP1 output1728 × 1296

Height 1296 > 1076! This means some ISP interpolation is happening to achieve the 4:3 ratio. But the quality is still far superior to the old 656x480.

656x480 is just the preview resolution sent to the display.

With a stock lens, even on D units, the maximum resolution for the active film scan will be around. 860x645, is only 10% higher than older models (from the slightly smaller pixels.) Going from 8mm to 12mm lens, is a 1.5X increase in X and Y res. So around 1290x960, in practice I'm seeing slightly more, like original lens in wider than 8mm.

As someone who scans with a Canon R5 and a Minolta Macro 50/3.5 on Minolta bellows and just happens to have a Kodak Eight Model 25 that hasn't been used yet (by me personally), this is an awesome project!

I develop color and B&W at home, so that's not a concern, I've just not gotten around to getting a roll of 8 mm yet since it only equates to about 2 minutes and 30 seconds of filming.
