Digital Imaging Characteristics Chapter
2 – Questions and Answers 100% Pass
What is an artifact in digital imaging?
✔✔ An unwanted visual defect or distortion caused by compression, processing, or sensor
limitations.
What is focal plane in digital imaging?
✔✔ The plane where the camera sensor or film focuses light to create a sharp image.
What is exposure latitude in digital imaging?
✔✔ The range of exposure settings where an image retains acceptable detail in both highlights
and shadows.
What is bitmapped image in digital imaging?
✔✔ An image made up of individual pixels, each with a specific color value, also known as a
raster image.
What is vectorization in digital imaging?
1
,✔✔ The process of converting a raster image into a scalable vector format.
What is high-pass filtering in digital imaging?
✔✔ A technique used to enhance fine details and edges in an image.
What is backlit imaging in digital imaging?
✔✔ A method where light shines from behind the subject, often creating silhouettes or enhanced
contrast.
What is adaptive contrast enhancement in digital imaging?
✔✔ A technique that adjusts brightness levels in different parts of an image to improve visibility.
What is luminance noise in digital imaging?
✔✔ Grain-like variations in brightness across an image, often appearing in low-light conditions.
What is chromatic noise in digital imaging?
✔✔ Unwanted color variations in an image, typically appearing as specks of red, green, and blue
in dark areas.
2
, What is soft clipping in digital imaging?
✔✔ A method of limiting highlights and shadows gradually to avoid harsh transitions.
What is tone mapping in digital imaging?
✔✔ A process that compresses the dynamic range of an image to display details in both
highlights and shadows.
What is pixel mapping in digital imaging?
✔✔ A correction method that detects and compensates for defective pixels in a sensor.
What is spatial resolution in digital imaging?
✔✔ The ability of an imaging system to distinguish small details and structures in an image.
What does contrast resolution refer to in digital imaging?
✔✔ The ability of an imaging system to differentiate between slight differences in shades of
gray or color.
