What input operation that requires a conversion to digital form prior to input?
An input operation that requires conversion to digital form prior to input is scanning a physical document. A scanner captures the image of the document and converts it into a digital format, such as a PDF or JPEG file, which can then be processed by a computer. This conversion allows for easier editing, sharing, and storage of the information contained in the document.
A concave mirror can form a real image which is a copy of an object that forms?
Yes, a concave mirror can form a real image that is inverted and smaller than the object. This type of image is produced when the object is placed beyond the mirror's focal point.
Describe the image form mirror by a plane mirror?
The image formed by a plane mirror is virtual, upright, and the same size as the object. The image appears to be behind the mirror at the same distance as the object is in front of the mirror. The orientation of the image is laterally inverted, meaning left and right are switched.
What is the difference between the object and the image?
An object refers to the physical thing being observed, while an image is a reproduction or representation of the object, typically in a visual form. The object exists in reality, while the image can be a reflection, photograph, drawing, or any other representation of the object.
What is the full form of JBIG?
JBIG is a Digital Image Format stands forJoint Bi-Level Image Group.
How does a concave mirror can form a real image which is a copy of an object that forms .?
A concave mirror can form a real image that is a copy of an object through reflection. When parallel rays of light converge towards the focal point of the concave mirror, they intersect and form a real image that is upside-down and a true representation of the object.
What is digital image processing?
Image processing is the method of processing data in the form of an image. Image processing is not just the processing of image but also the processing of any data as an image. It provides security.
What part of the eye refracts rays and forms the image of an object?
The cornea and the crystalline lens are responsible for refracting light rays to form the image of an object on the retina.
How do we use the ray model of light to show that the image formed in the mirror has the same size as the object?
When an object is placed in front of a plane mirror, the rays of light reflecting off the object form an image behind the mirror. By drawing incident and reflected rays corresponding to points on the object, using the law of reflection, we can show that the image is the same size as the object. This is because the incident and reflected rays form virtual images that are congruent to the object, thus showing that the size of the image is equal to the size of the object.
What uses a beam of light to create a digital image form artwork such as photos and drawings?
Scanner
Simple definition of scanner?
a scanner is an input device which is used to converet image into digital form
What is a copy of an object form by reflected or refracted rays of light?
Virtual Image
