Alising reduction method for color digital still cameras with a single-chip charge-coupled device

摘要

This paper presents an aliasing reduction method for digital still cameras(DSCs)which takes advantage of the color- signal correlation. The authors have developed a method of reduc- ing aliasing by increasing the resolution of the color signals in DSCs using a single-chip charge-coupled device with a primary-color filter array. The new method interpolates the signals by taking advantage of the fast that color-signal variations are similar to one another in a local region of an image.
