Not pixel size lah... pixel size does not come into the equation.
Circle of confusion is determine by the 'resolution' of the human eye. The ability of the human eye to detect the blur in the image. The circle of confusion is expessed in the final image/print and the distance at which the image is viewed.
Focal length and aperture will determine the "amount of blur" projected onto the sensor/film. The 'blur' is than magnified into the final image/print. The amount of magnification is affected by the size of the sensor/film and how big the final image is. How much blur can be detected by the human eye is also affected by the distance you are viewing the photo.
This should be discussed in another thread. (I think this has been discussed before.)
