Digital still cameras

This item was taken from the IEEE Periodical ' Digital still cameras ' This paper presents an interpolation method for digital still cameras (DSCs) which is based on color signal correlation. The authors have developed a method of reducing aliasing by increasing the resolution of color signals in DSCs that use a single-plate charge coupled device (CCD) with a primary color filter array. The new method interpolates signals by taking advantage of the fact that color signal variations are similar to one another in a local region of an image. It selects the signal that shows the higher correlation, either in the horizontal or vertical directions, at color signal positions subject to interpolation, thus improving the color resolution. First, the effectiveness of the new method was verified using image simulation. Next, the prototype hardware was fabricated. The prototype is fitted with an original reduced instruction set computer (RISC) built-in dynamic random access memory (DRAM) for processing image signals to provide high-speed camera signal processing. The authors also confirmed that the effectiveness of the new method was also established in actual products.
