Camera Technology

  • Types of Sensors
    • CCD - One of the oldest designs, charge-coupled devices are still one of the leading types of image sensors.
    • CMOS - A newer type of imager that allows engineers more flexibility in designing the sensor than the older CCD design.
    • LBCAST - Similar in design to CMOS sensors but using a different type of transistor in their underlying design to help decrease noise levels.
    • Foveon X3 - A proprietary technology that allows image sensors to read all three colours in a single photosite.
  • Sensor Technology
    • Bayer Filter Array - Allows inherently monochromatic image sensors to capture and interpret colour information.
    • Anti-Aliasing Filter - A special filter that adds a small amount of blur to captured images in order to prevent aliasing artifacts.
    • Microlenses - Tiny lenses placed above each photosite in order to maximize the sensitivity of the imager.
    • Electronic Shutter - Used in some types of image sensors, electronic shutters eliminate some of the limitations imposed by mechanical shutter assemblies.
  • Memory Cards
    • Compactflash - A larger form of flash memory common in high-end DSLRs.
    • Secure Digital - A type of flash memory with a very small footprint and used in many different types of cameras.
  • File Formats
    • JPEG - A compressed image format that provides much smaller file sizes than alternatives while maintaining most of the quality.
    • TIFF - Provides either uncompressed or losslessly compressed storage for digital image files without any loss in quality. Unfortunately, these files are generally quite large so they can be difficult to manage.
    • RAW - Proprietary file formats that store minimally processed data taken directly from the sensor. Requires additional conversion steps, but provides the highest level of flexibility.
    • DNG - Adobe's attempt to create a standardized RAW file format, provides many of the benefits noted above but is an open standard.
  • Metadata
    • EXIF - The standard metadata format used by almost all digital cameras. Primarily used to store information about the camera settings that were in use when the image was captured.
    • IPTC - A standard used to store editorial captioning information. Generally added manually by the photographer so that the image can be added to a database and properly indexed.
    • XMP - An upcoming metadata platform that uses an extensible format allowing a wider-range of information to be stored in image files.
