1. Test overview.
This test is used to verify that the ADDR functions correctly.
The scanner will scan a standard film containing scratches and dirt and will display the corrected and the non corrected image. The user will judge of the ADDR effectiveness.
If the ADDR does not function very well or at all, the customer could complain that the scanner does not remove dirt and scratches properly.
2. Conditions of the test.
This test relates to the 120 film carrier inserted in the scanner.
The 120 film carrier must be inserted in the scanner to carry out this test.
A standard film (short preferably), containing dirt or scratches on the first exposure must be used for this test.
The acceptance of the test is manual.
No parameter is saved.
3. Requirements.
- Test 120 Sharpness-CoeffG Test is accepted to ensure that the sharpness in the centre of film is to its maximum.
- Test 120 Cal Encoder 2 Test is accepted, the shift RGB - IR on each top encoder is calibrated.
- Test 120 Cal RGB IR Test is accepted to ensure that the shift of IR image ratio compared with the RGB image ratio is calibrated.
4. Realisation of the test.
Click on RUN to execute the test. A message will appear requiring the insertion of the film (first exposure containing dirt or scratches ). When the film is inserted, click on OK.
The scanner will scan the first exposure of the film then will display several images :
- The RGB image, can pass from a 0% correction to a 100% correction thanks to an ADDR efficacity button.
- The IR image, checks the presence of dirt and scratches.
- Differences between the IR image and the RGB image.
Click then on OK then on ACCEPT to accept the test.
Note : The correction is better on average resolution than into High resolution. Also, the test 120 ADDR uses the Average resolution.
5. Acceptance of the test.
It is up to the user to judge the effectiveness of the ADDR. If the corrected image is acceptable (removed scratches and dirt), the test can be accepted.
6. Other affected tests.
None.
7. Trouble shooting.
If the effectiveness of the ADDR is not sufficient :
- Redo test 120 Cal RGB IR then start again the test.
- If not, remake tests 120 Cal Encoder 2 then 120 Cal RGB IR then relaunch the test.
- If not, check for sharpness then remake the tests 120 C Al Encoder 2 then 120 Cal RGB IR then restart the test.
