The code indicated that it's cropped, but wouldn't that mess with viewing angles? Hm.

The bitstream is in one of the accessible SPI flashes, but reversing that is a pain.

E: Checked the datasheets. E76/E86 have 17um pitch, E96 has 12um. This gives a sensor size of 5440, 7888, 7680 respectively. This means that the sensor is, in fact, cropped.

However, it's unclear how it manages to maintain the FOV.

E2: Requesting a /dev/mtdblock{0,1} dump from a E75 and E86 please, if someone has access.

Would a similar dump from an E54 help? (it's still listed as current model / should be more in line with E76/E86/E96.. )

The E76+E86 likely share a 17um pitch sensor (probably an ULIS UL 04 27 2), while the E96 has a 12um pitch sensor (probably i3system DB640-12C-A). I haven't taken it apart so I don't know for sure, but someone DM'd me those specs last year. This means that it's not possible to use the full 640x480 resolution without prohibitive reverse engineering efforts, and even then it might be occluded by the hardware design (12um 640x480 is a smaller optical window than 17um 640x480, but the two systems share lenses => 17um will have clipped or distorted peripheral image at full resolution)

FLIR manufactures their own sensors.
The entire E7x and E8x series shares the same 640x480 sensor.

If you check the datasheet, E76+E86 have a 17um pitch sensor. E96 has a 12um sensor.

Good morning everyone,

I have recently added to my Flir stable the E96 (I know, I know.. )

If someone needs anything extracted from it - let me know (-:


Cheers,
aproape
