1.8 Imager File Update
The CMOS's defect data can be updated.
* CMOS is susceptible to ultraviolet rays and cosmic rays. Therefore, avoid
leaving a bare CMOS in the open. Store it in a dark place. Also, beware of static
charge. When handling the CMOS with bare hands, be sure to wear grounded
wrist bands.
1. Procedure
<Obtain the imager data of the camera. (Contact Head quarters in your region or access
the FTP site.)>
<Find the defect location specified by the user.>
1) Start up EOSD60Compiler.exe, and open the problem file specified by the user.
Compiler.exe can handle only RAW images. If the image file is JPEG format,
handle the file as a RAW image
referring to "Confirmation
Method." The figure on the right
shows the differences between a
RAW image (2496
×
1662) and
JPEG (Large-Fine: 2646
×
1648)
image. With image processing
software such as Photoshop, the
top left coordinate is expressed
as (0,0), whereas on
Compiler.exe, it is expressed as
(1,1). For this reason, in the case
of positions pointed out by the
user, the defect location at (1234,
321) on a JPEG (Large-Fine) image
is expressed differently as follows:
X=1234+72+1=1307
Y=321+16+1=338
2) Find the defect. Select the RAW
file by "OPEN" from "FILE" in the
figure on the right.
Part 4: Electrical Adjustments
4-13
To find the correct location of CMOS defects, a RAW image must be
used instead of JPEG which blurs the defect. The defect location
coordinates to be input are also based on the RAW image.
EOSD60_complier.exe will calculate the location with the full size
pixel of CMOS.That causes the number of pixels' differece from the
full size pixel images(3152
×
2068) to the JPEG (Large-Fine : 3072
×
2048).
The "defect" found could also be a piece of dust, etc. Before
starting, be sure to clean the CMOS.
