1. Which explanation matches read the intensity distribution?A. A piecewise mapping uses different input-output slopes across intensity intervals.B. Gamma encoding changes the relationship between stored display values and light intensity.C. Windowing selects a display range and maps it to visible output values.D. A histogram counts pixels at each intensity but discards where those pixels lie.

2. Which explanation matches design a piecewise brightness mapping?A. A histogram counts pixels at each intensity but discards where those pixels lie.B. Gamma encoding changes the relationship between stored display values and light intensity.C. A piecewise mapping uses different input-output slopes across intensity intervals.D. Windowing selects a display range and maps it to visible output values.

3. Which explanation matches gamma and display values?A. A histogram counts pixels at each intensity but discards where those pixels lie.B. Gamma encoding changes the relationship between stored display values and light intensity.C. A piecewise mapping uses different input-output slopes across intensity intervals.D. Windowing selects a display range and maps it to visible output values.

4. For design a piecewise brightness mapping, which result or action fits this practical case: The archivist wants to brighten shadows without washing out highlights.A. Map dark input values more steeply while keeping the bright interval gentler.B. Compare two images with the same histogram but different placement of dark regions.C. Compare a middle encoded value with half the physical light level rather than assuming they are equal.D. Show both a narrow window for a faint mark and a wide window for the overall scan.

5. For window a high-bit-depth image safely, which result or action fits this practical case: A 16-bit scan looks nearly black when shown in an 8-bit viewer.A. Compare two images with the same histogram but different placement of dark regions.B. Map dark input values more steeply while keeping the bright interval gentler.C. Compare a middle encoded value with half the physical light level rather than assuming they are equal.D. Show both a narrow window for a faint mark and a wide window for the overall scan.
