This week I was assigned to draw the schematic for the demosaicing algorithm. The algorithm is separated into two parts, which is bilinear interpolation in the boundary of image, and PPG interpolation for the rest of image pixels. The Overview of Demosaicing Schematic The hardware implementation of the demosaicing requires Read more…
This week, I spent my time to understand and test the demosaicing algorithms in C. Finding the Right Algorithm I had done a lot of searching through the Internet, try to figure out what is the best algorithm to be used, and implement it in C program so that I Read more…
This week, I had been spending time searching on way to test the demosaic algorithm. I did a misunderstanding on previous week, that there is a process between the image sensor output and raw image. The Raw image is directly the output from the image sensor output itself. Well, I could Read more…
This week, I have to choose which area of chip design that I am going to involved in, and I decided to work on the accelerator for chip design. I had chosen to work on the accelerator for Image Sensor, to accelerate the image sensor output into a raw image Read more…
This week I was given another task about the CCD optical sensors. CCD is called Charge-coupled device where it is capable of transforming light pattern from an image into an electric charge pattern just like an electronic image. It can collect, store and transport electrical charge from one element to another. Each pixels Read more…
