Match List I with List II Choose the correct answer from the options given below:List I List II A. 2-D Array Input I. Liquid Crystal display B. Transmissive device II. Flat-bed scanner C. Binary image III. Camera D. 1-D array input IV. Ink jet printer
A-III, B-I, C-IV, D-II
Imaging devices are classified by how they sense or render a picture: area (2-D) sensors capture a whole frame at once, line (1-D) sensors capture one row at a time and sweep, transmissive displays modulate light passing through them, and binary output devices place dots that are either on or off.
A — 2-D Array Input: a camera uses a two-dimensional CCD/CMOS sensor array that captures the whole image in one exposure, so A-III.
B — Transmissive device: a liquid crystal display modulates light from a backlight that passes through the liquid crystal cells, so B-I.
C — Binary image: an ink jet printer deposits a dot of ink or none at each position, producing a binary image (grey levels are simulated by halftoning), so C-IV.
D — 1-D array input: a flat-bed scanner moves a single linear sensor row across the page and builds the image line by line, so D-II.
Codes that place the camera or the scanner opposite the display, or the printer opposite the 1-D sensor, confuse capture devices with rendering devices.
A-III, B-I, C-IV, D-II option is correct.
