information or improve quality.
The primary goal is to create visual content The primary goal is to modify or extract
that can be understood by humans, often information from digital images, typically
for informative purposes. through algorithms and techniques.
Computer graphics is used in movies, video Image processing is used in medical imaging,
games and flight simulators for graphic satellite imaging, facial recognition, editing, etc
purposes. for better imaging.
Computer graphics produces new images Image processing modifies or enhances
from scratch or modifies existing ones to existing images, mostly without fundamentally

Computer Graphics often requires powerful It can be implemented on standard computing
graphics processing units (GPUs) and hardware but may require parallel processing
rendering hardware. units for efficiency.
Can produce highly complex visual scenes Outputs are often simpler, focusing on

lighting and shadows. image, such as contrast or texture.
Applications of Computer Graphics
Computer graphics is used in computers for manipulating, creating and storing various
types of objects as well as images, some applications of computer graphics are
mentioned below:
• By using the computer graphics we can create different types of arts such as
commercial and fine art and animation packages etc.
• With help of computer graphics we can create presentation of various reports
such as financial and statistical data and economical reports.
• Computer graphics is also majorly used in the entertainment industry such as
game and movie industry etc.
• By using computer graphics we can design various drawings for buildings,
aircraft schematics and automobile design etc.
Applications of Image Processing
Image processing is also used in computers for manipulating the different parameters of
images, some applications of image processing are mentioned below:
• Image processing finds its use and availability in the field of image sharpening
and also helps in the restoration of images.
• Image processing is used in the medical field in order to find patterns in the
medical reports and help in enhancing the image to find conclusive reports.
• Image processing is also used in the field of transmission and encoding for
faster and smoother transmission of images.
• It is used in the field of color processing and enhancing the color of various
images to give it more clarity.
