CONCLUSION


Intensity and colour values for each picture in horizontal and vertical rows of pixels.

User control inputs.

Output is encoded file for a picture.

Permanent store of the picture at a file in a flash memory sick.

Screen display of picture from the file after decoding


Keys on the camera.

Shutter, lens and charge coupled device (CCD)

array sensors

Good resolution photo quality LCD display

unit

Displays text such as image-title, shooting data

and time and serial number. It displays

messages. It displays the GUI menu when user interacts with the camera.

Self-timer lamp for flash.


Internal memory flash to store OS and

embedded software and limited number of image files.

Flash memory stick of 2 GB or more

for large storage.

Universal Serial Bus (USB), Bluetooth and serial COM port for connecting it to computer, mobile and printer.


Microcontroller or ASIP (Application

Specific Instruction Set Processor).

Multiple processors (CCDSP, DSP, Pixel

Processor and others).

RAM for storing temporary variables and

stack.

ROM for application codes and RTOS

codes for scheduling the tasks.


SYSTEM LAYER

APPLICATION LAYER

FUNCTION LAYER

PRESENTATION LAYER

CONTROL LAYER

BASE LAYER


CCD signal processing

JPEG coding

JPEG decoding

Pixel co-processing

LCD and USB Port device drivers

LCD, Bluetooth COM and USB Port device drivers

Light, flash and display device drivers


System layer provides system services

Example:

Display the text with picture,flash start and stop and services such as IPCs(Inter Process Communication)

APPLICATION LAYER : Application layer is for system switches,

button and control tasks.


Function layer is for appilcation layer tasks functionality using Picture_FileCreation, Picture_FileDisplay and Picture_FileTransfer.

PRESENTATION LAYER:

Presentation layer is for providing standard acess to an image file


By using digital camera we can capture images and videos.

And this data can be transfered into a computer by using various devices.

We learnt the digital camera hardware and soft ware architecture.
