The sensitivity of a (digital or film) imaging system is typically described in the terms of the signal level that yields a threshold level of SNR. Industry standards define sensitivity in terms of the ISO film speed equivalent, using SNR thresholds (at average scene luminance) of 40:1 for "excellent" image quality and 10:1 for "acceptable ...
Compared to film, digital cameras are capable of much higher speed (sensitivity to light) and can perform better in low light or very short exposures. The effective speed of a digital camera can be adjusted at any time, while the film must be changed in a film camera to change the speed.
The most common is the simple interrupted stitch; [12] it is indeed the simplest to perform and is called "interrupted" because the suture thread is cut between each individual stitch. The vertical and horizontal mattress stitch are also interrupted but are more complex and specialized for everting the skin and distributing tension.

Each lens used with the camera must be calibrated carefully to ensure that the image is focused on the exact spot where the individual frame of film or digital sensor is positioned during exposure. film production film recorder film release film scanner film score
The middle stitch is a vertical mattress the others simple interrupted stitches. The vertical mattress stitch, often called vertical Donati stitch (named after the Italian surgeon Mario Donati), [1] is a suture type used to close skin wounds. The advantages of the vertical mattress suture are that it provides closure for both deep and ...
The simple interrupted stitch is a suturing technique used to close wounds. It is the most commonly used technique in the closure of skin. [1] It is known as an interrupted stitch because the individual stitches aren't connected; they are separate. Placing and tying each stitch individually is time-consuming, but this technique keeps the wound ...
As the film was run at the same speed as the television, the flickering was eliminated. Various displays, including projectors for these video rate films, slide projectors and film cameras were often combined into a film chain, allowing the broadcaster to cue up various forms of media and switch between them by moving a mirror or prism.
