4 Image Processing Overview Common terms 32 This chapter introduces concepts that may be new to many users. The Kodak i30 and i40 Scanners provide the ability to process scanned images to improve their quality. Using these features the scanner can sometimes make the scanned image look better than the original document. Basic image processing concepts are reviewed in this chapter to help you take advantage of these powerful features. Image processing refers to several separate features of the scanner that allow you to automatically adjust each image in a certain way that may improve the resulting images. Common examples of image processing features are correcting any skew in the fed document, cutting the edges of the image off to remove any unneeded border or cleaning up extraneous "noise" on the image. The idea is to do this automatically so you can get better images with a minimum amount of rework. The information that follows describes the image processing features by walking you through the Scan Validation Tool. The same options should be available on the user interface of the software application you are using (i.e., Kodak Capture Software). All fields on the Scan Validation Tool are described in this chapter. Following are a few common terms that are used throughout this chapter: Bi-tonal or Binary - black-and-white. Simplex - indicates that only one side of the document (the front side) will be scanned, creating a single page image. Duplex - indicates that both sides of the document will be scanned, creating two page images. Cameras - it is important to understand the concept of "cameras". The Kodak i30 Scanner is a simplex scanner. The camera has the ability to separate color and bi-tonal/binary data simultaneously. This means it scans one-sided documents; a front color camera and a front bi-tonal/binary image, allowing you to capture one side of a document either in color/grayscale or black-and-white with a single scan. The Kodak i40 Scanner is a duplex scanner. The cameras have the ability to separate color and bi-tonal/binary data simultaneously. This means it scans both sides of a two-sided document; a front color image, a rear color image, a front bi-tonal/binary image, and a rear bitonal/binary image, allowing you to capture both sides of a document in either color/grayscale, black-and-white, or a combination of color/ grayscale and black-and-white with a single scan. When you use the Kodak Scan Validation Tool, you will need to select which camera(s) you want to use to scan your document to get the desired results. You can use the following examples as a guide when making camera selections. A-61512 May 2006
