Pearleye Technical Manual V2.3.0

Example

Integration of 32 images simultaneously to the output of the actual integration

image (a=2, b=6) => abbba = 11100 [binary] = 0x1A. After that, reactivate the

background correction.

Command sequence

>U=1A[CR]

Pearleye P-007 LWIR ...wait for at least 34 image cycles (32 + 2 frames jitter buffer, 0.85 seconds at

40 images / second) or poll the state of bit group c with U[CR]...

Pearleye P-030 LWIR ...wait for at least 34 image cycles (32 + 2 frames jitter buffer, 1.41 seconds at

24 images / second) or poll the state of bit group c with U[CR]...

>U=1[CR]

Bit group Value (hex) Explanation

a 0 Output: deactivated. Data is passed through transparently.

1 Output: activated. Apply the current correction image (H/U) and offset

value M.

2 Output: activated. Output of current correction image (H/U).

b 0 Integration: deactivated. The image store content is not changed.

1 Integration: 1 image. The following image is copied into the image

store.

4 Integration: 8 images. The following 8 images are integrated and the

result is copied into the image store.

5 Integration: 16 images. The following 16 images are integrated and the

result is copied into the image store.

6 Integration: 32 images. The following 32 images are integrated and the

result is copied into the image store.

7 Integration: 64 images. The following 64 images are integrated and the

result is copied into the image store.

c 0 Integration completed. (This value can only be read out.)

1 Integration still running. (This value can only be read out.)

Note: The Integration is activated by change of the bit group b of U.

If e.g. directly following the integration of 64 images a further integration of 64 images is subject

to be started another value has to be written into the register first.

Example: U=E, U=0, U=E.
