Abstract
A new technique to design mosaic color filters
on a CCD area sensor is propose to improve
the quality of electronic endoscope image.
Images obtained from the CCD sensor have
an interpolation error. The error causes
degradation of spatial information in the
reproduced image, In this paper, we analyzed
spectral distribution of the reflectance
spectra in the electronic endocarp image,
and the distribution was used to optimize
the spectra transmittance of the color filters
for improvement of image quality. The simulated
annealing technique was utilized for optimization.
