How does a scanner differ from a digital camera?

• A scanner is used for video recording, while a digital camera is for still images.

• A scanner captures images in 3D, while a digital camera captures images in 2D.

• A scanner captures images of documents, while a digital camera captures images of scenes.

• A scanner takes photos of people, while a digital camera scans documents.

What is a color model in the context of images?

• A color model is a software tool for editing images.

• A color model is a physical object used in photography.

• A color model is a mathematical representation of colors used in digital images.

• A color model is a type of image filter.

Explain the concept of Device Independent Color Models.

• Device Independent Color Models rely on specific hardware settings for color accuracy.

• Device Independent Color Models are only applicable to printing devices.

• Device Independent Color Models are used to enhance device performance.

• Device Independent Color Models provide a consistent way to represent colors across different devices, ensuring uniformity in color appearance.

What role does image processing software play?

• Image processing software only compresses files.

• Image processing software is used solely for printing images.

• Image processing software is designed to create 3D models.

• Image processing software enhances and analyzes images for various applications.

List two common file formats for images.

• JPEG, PNG

• TIFF

How is text insertion typically handled in digital documents?

• Text insertion is handled by placing the cursor and typing at the desired location.

• Text insertion requires a special software tool.

• Text can only be inserted at the beginning of the document.

• Text insertion is done by copying and pasting from another document.

What are the specifications of digital images?

• Image brightness and contrast

• Camera model and lens type

• Subject matter and composition

• Specifications of digital images include resolution, color depth, file format, aspect ratio, and compression.
