Abstract:
We face multiple technical tasks when designing and developing digital cameras for consumer use. As would be expected, image quality is a top concern. Digital still cameras fall into two categories. One uses a black box and a camera lens with a CCD (charge-coupled device) back unit that can acquire more than 3 million pixels. Designed for professional and business use, this camera normally costs more than $5,000. The second type of digital camera is designed for consumers and employs a CCD capable of acquiring 350,000 to over 1 million pixels (Mpixels). Because it is easy to handle and carries a reasonable price for the picture quality, its market has grown dramatically in last three years. Here, I discuss the image-capturing system for a consumer-use digital still camera after briefly explaining its history
