Kamerasensorencodierung

Kamerasensorencodierung refers to the process by which raw data captured by a camera's image sensor is converted into a digital format that can be stored, processed, and displayed. This involves several stages, starting with the light hitting the photosensitive elements of the sensor. These elements, typically photodiodes, convert incoming photons into electrical charges. The magnitude of this charge is proportional to the intensity of the light.

Following the charge accumulation, an analog-to-digital converter (ADC) transforms these analog electrical signals into discrete digital values. This conversion is crucial as computers and digital devices operate on digital information. The resolution of the ADC, measured in bits, determines the number of distinct tonal levels that can be represented for each pixel. Higher bit depth allows for a wider dynamic range and more subtle gradations of color and brightness.

Furthermore, Kamerasensorencodierung often includes demosaicing, a process necessary for color sensors. Color sensors typically use a color filter array (CFA), such as the Bayer filter, where each pixel only records the intensity of one primary color (red, green, or blue). Demosaicing algorithms interpolate the missing color information for each pixel based on its neighbors, reconstructing a full-color image. Other encoding steps might involve noise reduction and initial image processing before the data is saved in a specific file format like JPEG or RAW.
