Analog Photographic film - 1980s-1990s years

Analog photography is a commonly used term for photography that uses a progressively changing recording medium, which may be either chemical process based (e.g.,photographic film or plate) or electronic (e.g., vidicon or CCD sensor). Through common use this term has come to mean anything that is "not digital" despite some amount of controversy that the use of film isn't a true "analog" process.[1][2]

In a film camera that uses the gelatin-silver process, light falling upon photographic emulsions containing silver halides is recorded as a latent image. The latent image is subjected to photographic processing, which makes it visible and insensitive to light.

In a video camera or digital still camera, the signal is captured with a video camera tube orcharge coupled device sensor, which sends the picture to be processed by the camera's electronics. The signal can be transmitted or recorded on a storage device for later playback.

How does a frame grabber work In particular I am looking for a simple diagram but any information would be helpful?

Hii. A frame grabber is an image acquisition board which can be of 2 types: Analog and Digital. In case of an analog frame grabber, we use an analog camera and digital camera for Digital frame grabber. In analog frame grabber the analog image signal is digitised (using A/D converter), then sent to a buffer memory. From there it is transferred to host memory i.e. RAM where processing talkes place. If no processing is required then the image can be displayed directly from the grabber buffer. It generally takes input from ADC at very high speeds, typically 60MHz and outputs at 20MHz so that no frame is lost. It also has standard I/O like a parallel port. In case of a digital frame grabber the image is already digitised.

Why scanning is necessary in tv transmission?

scanning is done to sample the image as digital information is more easy to be transmitted than the analog information...


What is the analog definition in computer science and how does it relate to modern computing technologies?

Analog in computer science refers to a continuous signal or data representation, as opposed to digital which is discrete. Analog technology is used in modern computing for tasks like sound processing and image recognition, where continuous data is more suitable than discrete data.
