If your JPEG image file shows invalid colors than this is a hint that the byte stream of you file is damaged at several positions. That is to say your file has some memory errors within its data stream. These issues lead to wrong and erroneous image colors for the whole image file. For each memory fault a new color appears on the JPG image. You can learn more about this type of error at: JPEG errors
Are your JPG picture colors damaged this way and you wonder whether you can recover your image files? The answer is: Yes.
Based on our 12 year experience in JPEG image recovery, we offer a client application for manual recovery of JPEG color errors.
Repairing JPEG Color errors is done in four easy steps:
A detailed application help will be provided soon at this place.
JPEG files are encoded in small blocks, called "MCU" (Minimum Coding Unit). All file operations are performed based on the MCU and not based on pixels.
VG JPEG-Repair Online - MCU Editor works with command keys. That is to say you just will work with keys instead of menus that are controlled with your mouse. Beside a lot of display, file, MCU copy and paste operations, you have two main operations for color recovery:
All file parts that still contain a visible area of the image motive can be repaired. I.e. all image parts that are displayed with wrong colors, can be recovered. Faulty positioning and shifting of image parts can be repaired, too.
In general, all image regions that still consist (and are in wrong color or location) can be recovered.
Parts that do no more contain any visible part of the image can't be reconstructed because for these areas the according memory bytes of the JPEG image file are completely destroyed. But such parts usually are very small, fortunately. If we repair your photo, we will replace such irreparable parts with other parts duplicated from somewhere in the image. So these parts will no more be conspicuous.
If your images miss complete regions of the picture, a recovery of these areas is not possible at all. Please consider that once the image parts are lost due a memory error, they are gone forever.
