Abstract

We compared the Spatial Frequency Response (SFR) of image sensors that use the Bayer color filter pattern and Foveon X3 technology for color image capture. Sensors for both consumer and professional cameras were tested. The results show that the SFR for Foveon X3 sensors is up to 2.4x better. In addition to the standard SFR method, we also applied the SFR method using a red/blue edge. In this case, the X3 SFR was 3-5x higher than that for Bayer filter pattern devices.
