The Book Image Processor is a small Java utility I wrote for post-processing photographed images of book pages into a format that can easily be compiled into an ebook. It is part of my book scanner build tutorial.
Features
- Rotate images, convert them to grayscale or black and white, and adjust brightness and contrast.
- Crop images to the page dimension. The "End Crop" lets you set one crop setting at the beginning of the image set, and another at the end of the image set. Then the crop settings are interpolated between the two settings for the entire image set. This allows the cropping to more closely follow the page, since the position of the page is not uniform through the book (due to the thickness of the book.
- Preview pane - lets you see what the output for a particular image will be. Select any image from the image list and click the "update preview" button. Note that the preview is not automatically updated when settings are changes, you must continue to click the Update Preview button after each change.
- Separate settings for left and right (even and odd) images allow you to process all the images in one batch.
- Interleaving and uniform file renaming - specify a uniform filename for the output files while automatically interleaving left and right images. You can specify the starting index of the output files so that you can process images in batches (for example, if your camera memory is limited).
- Save and Load profiles - You can save profile settings for reuse to speed up image processing. The last settings used are automatically saved, or you can explicitly load a saved setting from the Output Settings tab

Support
This is a pretty simple program and targeted toward more technical users, so I do not intend to provide much support or documentation beyond the above. If you have any questions, you may send inquiries to This e-mail address is being protected from spambots. You need JavaScript enabled to view it or twitter to @314piesJR. This was put together fairly quickly, so it doesn't have a lot of polish, but it gets the job done. It was designed with a specific workflow in mind, so you may find bugs if you use the software differently. You should always keep a backup copy of your book images until you are finished processing and compiling your PDF.
