1. Image Sensors:
• Two elements are required to acquire digital images: a
sensor and a digitizer.
• Sensor - sensitive to the energy radiated by the object we
wish to image.
• Digitizer - Device for converting the output of the physical
sensing device into digital form.
• Example, in a digital video camera, the sensors produce an
electrical output proportional to light intensity. The digitizer
converts these outputs to digital data.

2. Specialized image processing hardware:
• Consists of the digitizer and hardware that performs
other primitive operations, such as arithmetic logic unit
(ALU).
• ALU performs arithmetic and logical operations in
parallel on entire images.
• ALU is used in averaging images as quickly as they are
digitized, for the purpose of noise reduction.
• Hardware sometimes is called a front-end subsystem,
and its most characteristic is speed in which they
process image.

5. 3.Mass storage:
• Capability is a must in image processing applications.
Digital storage for image processing applications falls into
three principal categories:
(1) short-term storage for use during processing
(2) on-line storage for relatively fast recall, and
(3) archival storage, characterized by infrequent access.
