Abstract
An anti-color aliasing filter for a digital imaging system is includes a first filtering region that allows any color to pass through. The filter also includes a second filtering region adjacent to the first filtering region to allow a particular color or colors to pass through in order to adjust the color frequency response of the digital imaging system to the remaining colors without affecting the frequency response of the digital imaging system to the colors passing through the second filtering region, such that color aliasing is minimized in the digital imaging system.
