Recently, medical endoscopes with CCD camera devices have been developed and aroused great interest because of a larger number of picture elements than conventional endoscopes with optical fiber bundles. One type of image acquisition system is such that color images are sequentially taken with red (R), green (G) and blue (B) illuminations. This type has the merit of a good spatial resolution but constructed images are sometimes blurred or color shifted because of a rapid object motion while recording three primary color images. Since three primary color images have strong correlation, this problem can be solved by a compensation method using phase correlation l). This paper shows an advanced technique named the color deviation method which is much simpler than the previous method.
