Error #52 coming up for JPEG image
|
|
| siddhugp@gmail.com 2007-08-15, 6:56 pm |
| I recently recovered some important jpeg images and .mov videos from a
memory card that was erased.
When I read the image using exifer, it gives me JPEG error #52.
The image files are 1.5-2mb, so they seem to have the image data, but
I'm not sure if the header is missing or the image is corrupted.
Could someone check out this image and tell me if they can be read?

Thank You!

I'm not sure.
The first 0x80000 bytes shouldn't be there.
At 0x80000 it starts as a reasonable Exif file, but it's corrupted
about 30% through the main image.
I'll play with it for a while, and see what I can do.
I think the D40 may have three images, so I may be able to
extract at least a full intermediate sized image.

The D40x has a 160 x 120 thumbnail, and a
570 x 375 intermediate image.
These are OK on your file, but I don't think I have
all the data for the main image.

I tried taking the bogus data from the start of the file,
and appending it to the end of the main image, but
it appears to be from another image. I think the OPs
recovery program messed things up.
The OP also mentioned the files are about 1.5MB to
2MB. That seems too small for a 3872 x 2592 image
with such a mild quantizing table. The review image
I downloaded off the web for 4 MB.

I did much the same as you. Results are here:

Two small images recovered, one larger broken image.
