Methods and systems for adjusting text colors in scanned documents

A multi-function device for adjusting text colors in scanned documents, the multi-function device comprising:

• a receiver for receiving a document from a user for scanning;
• an electronic scanner for scanning the received document to generate scanned data in a mixed or multiple raster content file format;
• and
• a color adjustment module for:
• segmenting the scanned data into a background layer comprising an image layer and a foreground layer comprising one or more text layers, wherein the one or more text layers comprise textual content having one or more text colors;
• identifying text color intensity values of pixels representing the textual content in each text layer;
• calculating the text color intensity values associated with the textual content in each text layer based on scan performance of the electronic scanner;
• for each text layer, comparing the text color intensity values of each pixel of the textual content that are identified and calculated in the text layer with one or more pre-defined colors, wherein the one or more pre-defined colors represent frequently appearing text colors in documents and text colors of one or more templates of documents or reports at a multi-function device;
• based on the comparison, adjusting the text color intensity values of each pixel of the textual content in the text layer to match with the one or more pre-defined colors, thereby, generating a modified text layer;
• and
• combining the modified text layer and the image layer to generate a final scanned document.

A non-transitory computer-readable medium storing instruction, which when executed by one or more processors cause the one or more processors to:

• receive a document for scanning from a user;
• scan the document to generate scanned data in a mixed or multiple raster content file format using an electronic scanner;
• segment the scanned data into a background layer comprising an image layer and a foreground layer comprising one or more text layers, wherein the one or more text layers comprise textual content;
• identify text color intensity values of pixels representing the textual content in each text layer;
• calculating the text color intensity values associated with the textual content in each text layer based on scan performance of the electronic scanner;
• for each text layer, compare the text color intensity values of each pixel of the textual content that are identified and calculated in the text layer with one or more pre-defined colors, wherein the one or more pre-defined colors represent frequently appearing text colors in documents and text colors of one or more templates at a multi-function device;
• based on the comparison, adjust the text color intensity values of each pixel of the textual content in the text layer to match with the one or more pre-defined colors, thereby, generating a modified text layer;
• and
• combine the modified text layer and the image layer to generate a final scanned document.
