Digital camera settings

Compared to analog cameras, digital cameras offer far greater flexibility because users can adjust camera settings with purchased software. In some cases, analog camera settings can be adjusted through hardware such as dual in-line package (DIP) switches or RS-232 connections. Nevertheless, the flexibility of modifying settings through software greatly increases image quality, speed, and contrast. This can be an important factor in determining whether a defect can be detected. Many digital cameras have built-in FPGAs (field-programmable gate arrays) for digital signal processing and camera functions. FPGAs perform not only the computation behind many digital camera functions but also additional functions such as simple image processing and color interpolation for mosaic filters (in the case of smart cameras). The camera firmware controls the FPGA and onboard memory. In some cases, the camera's firmware can be updated to add and improve features. A digital camera's onboard memory allows settings, lookup table storage, buffering for high-speed transfer, and multi-camera networking through Ethernet switches. Some of the most common digital camera settings are gain, gamma, area of interest, binning/subsampling, pixel clock, offset, and triggering. Understanding these basic settings will help you achieve the best results in a wide range of applications.
