Which one of the following determines the sharpness of image in a camera? (1) The aperture (2) The exposure time (3) The focal length of the lens (4) Size of the camera
by

1 Answer

Answer :

(1) The aperture Explanation: Image quality is a characteristic of an image that measures the perceived image degradation (typically, compared to an ideal or perfect image). Imaging systems may introduce some amounts of distortion or artifacts in the signal, so the quality assessment is an important problem. Sharpness determines the amount of detail an image can convey.
