These errors occur frequently and are caused by incorrect data transmission or erroneous reading of data. The data in a JPEG image is "differentially" written. If a particular spot is damaged, all subsequent parts of the picture will be displayed incorrectly. Exceptions are files that contain Restart-Marker, but most cell phones and cameras do not write any Restart-Marker into the image files. Depending on the severity of the damage, a restoration of the colors is possible.
Strong damage to the data stream often leads to complete destruction of the image. If individual parts of the image are not damaged too much, at least these parts can be restored. However, this is a complicated process, too. The relevant parts must be recognized in the data stream and must be removed. The restored image will start in the middle or in another part of the original motif. It is also possible that individual parts are totally missing within the picture. In this color space, the brightness, as well as the intensity of red and blue are stored in separate channels.
If the data stream or the JPEG header is damaged, it can happen that the color values "swell" and leave the permitted color space. The picture then shows intensely colored thick lines and blocks.
This error also causes the file to look different in different programs and browsers. If the header of a JPG file is still there, but damaged, it can cause the image to be displayed in a completely chaotic way. If these tables are damaged, the image will be "misassembled". Slight damage to the JPEG header can be repaired. In case of severe damage, it is necessary to replace the entire header with the header of another, not damaged file.
This header must necessarily come from the same camera or the same phone. If an image no longer contains a JPEG header, then it is not possible to display the image, at first. In such a case, however, a repair can succeed if the JPEG header is completely replaced by a new header.
This new header must necessarily come from the same camera or the same phone. When creating an image file, there is the option to "optimize" the information contained in the header. Unfortunately, if this optimization was done on the defective file, the header can not simply be replaced by another because it has been customized for the data stream. For this reason, repairing such a file, usually is possible with an arbitrary, undamaged file from the same device.
Our product is able to automatically repair a large number of different JPEG defects. The relevant information is extracted from the files, checked and, if possible, repaired directly. In this case, complicated methods of pattern recognition are used. Since it is sometimes difficult to determine which error is actually present, several different repairs are performed, which can lead to multiple results per file. However, this does not have to confuse you, you can simply select the appropriate file when downloading.
In order to always achieve the optimum result, we do not want to make an automated pre-selection here. As described above, restoring the image is often only possible by using a completely new JPEG header from another file.
This "sample file" must meet the following criteria: The image file must be undamaged The image file must be created by the same camera or mobile phone The picture must have the same resolution The picture should have been taken with the same settings When the user starts the analysis, our software evaluates all the appropriate JPEG headers from the sample files and uses them to repair the damaged image.
This usually leads to several results, that is, multiple result images. Sometimes we receive e-mails from people who have tried our free trial access but were unfortunately unable to recover the broken images.
