3. JPEG

JPEG is a lossy image compression algorithm that is used to reduce the size of digital images. It is one of the most widely used image compression algorithms in the world, and it is used in a variety of applications, including digital cameras, smartphones, and the World Wide Web.

• Compression
  JPEG is a lossy compression algorithm, which means that it reduces the size of an image by removing some of the data in the image. This can result in a loss of image quality, but it also allows for a significant reduction in file size.
• Quality
  The quality of a JPEG image can be controlled by adjusting the compression ratio. A higher compression ratio will result in a smaller file size, but it will also result in a lower image quality. A lower compression ratio will result in a larger file size, but it will also result in a higher image quality.
• Applications
  JPEG is used in a wide variety of applications, including digital cameras, smartphones, and the World Wide Web. It is also used in a variety of software applications, including image editing programs and web browsers.
• History
  JPEG was developed in 1992 by the Joint Photographic Experts Group (JPEG). The JPEG standard has been updated several times since its original release, and the latest version is JPEG 2000.

JPEG is an essential technology for the storage and transmission of digital images. It is a versatile algorithm that can be used to achieve a wide range of image quality and file size requirements.

4. Bayer filter

The Bayer filter is a color filter array (CFA) used in most digital cameras to capture color images. It is named after its inventor, Bryce Bayer, an engineer at Eastman Kodak. The Bayer filter is a mosaic of red, green, and blue filters that is placed over the image sensor. Each pixel on the image sensor is covered by one of the three filters, and the color of the pixel is determined by the color of the filter that covers it. This way, cheaper single-chip digital cameras are able to produce high-quality color images.

• Function
  The Bayer filter is used to capture color images by splitting the incoming light into three primary colors: red, green, and blue. This is done by placing a mosaic of red, green, and blue filters over the image sensor. Each pixel on the image sensor is covered by one of the three filters, and the color of the pixel is determined by the color of the filter that covers it.
• Importance
  The Bayer filter is an important part of digital cameras because it allows them to capture color images using a single image sensor. This makes digital cameras more affordable and compact than they would be if they used three separate image sensors for each color.
• Applications
  The Bayer filter is used in most digital cameras, including DSLRs, mirrorless cameras, and compact cameras. It is also used in some video cameras and smartphones.
• John Janssen
  John Janssen is a Dutch computer scientist and entrepreneur who is best known for his work on the JPEG image compression standard. He is also the inventor of the Bayer filter.
