Bayer flter mosaic. ? Color flter array placed over sensor. ? Result: each pixel measures incident red, green, or blue light. ? 50% of pixels are green pixels. - Human visual perception most sensitive to green light (in normal light levels). Traditional Bayer mosaic. Human eye: cone spectral response. (other flter patterns exist:

Pixel Non-Uniformity each pixel in a CCD has a slightly different sensitivity to light, typically within 1% to 2% of the average signal can be reduced by calibrating an image with a flat-field image flat-field images are also used to eliminate the effects of vignetting and other optical variations. Stuck pixels some pixels are turned
Have you ever wondered what happens behind the scene when you take a picture with your digital camera? Digital cameras perform a number of processing steps, referred to as a pipeline, to convert raw data from an image sensor into a high quality image.
Once the exposure finishes, the camera closes each of these photosites, and then tries to assess how many photons fell into each cavity by measuring the strength of the electrical signal. The signals are You might wonder why the first diagram in this tutorial did not place each cavity directly next to each other. Real-world
ISP algorithms such as auto white balance, histogram calculation and equalization, autofocus, demosaicing and denoising .. The main objective is to implement some of the functions in a camera ISP (Image Signal Processor) block so that they in the .. tutorial [6] is a starting point for many GPGPU interested. Generally a
essential component for a camera system, surprisingly, its architecture has not been analyzed in the context of standards. The purpose of this chapter is to remove ambiguity when analyzing an ISP architecture or designing a new ISP architecture. At the end of this chapter, a baseline ISP pipeline is presented, which is

Digital still color cameras (DSCs) have gained significant popularity in recent years, with projected sales in the order of 44 million units by the year 2005. Such an explosive demand calls for an understanding of the processing involved and the implementation issues, bearing in mind the otherwise difficult problems these.
22 Feb 2013 This is called demosaicing, and it's probably the primary job of ISP, and there are many secret sauce methods to computing this interpolated image. In addition ISP does all the other housekeeping, it controls autofocus, exposure, and white balance for the camera system. Recently correcting for lens
