Parts of a Digital CameraJust before you know how a camera works, I would

introduce you to all the parts of a digital camera.

• Diopter Adjustment Dial• Viewfinder• Monitor• Battery Compartment Lock• Monitor Button• OK/ Menu Button• Arrow Pad

A digital camera has 7 main parts

How A Digital Camera Works Just before you click the action button on the digital camera, you might

want to adjust the brightness or sharpness of the picture so simply turn the diopter adjustment dial to have a good picture as a result.

When you click the action button on digital camera, the light strikes a digital sensor array instead of a piece of film.

The digital sensor is a computer chip which is used in place of a piece of film.

The digital sensor is made of millions of tiny sensor points known as pixels.

(Continue) These pixels are arranged in an array with rows and columns like

in a wall calendar.

The pixels become excited when image strikes the sensor. The image then passes through color filters.

The sensor converts the image from light waves into an analog signal.

The analog signal is converted to a pure digital signal by the digital converter.

The signal will pass through a series of filters, during which white balance and color adjustments occur.

(Continue) Next the image size is adjusted by dumping unnecessary pixels,

and this is important for effective storage.

Now the camera has a nice compressed & filtered digital image.

After the process, the image is transferred into a temporary storage inside the camera which is the buffer memory.

When the buffer memory is full, the image is stored in the memory card.

The size of the buffer memory is important, since it will tell how many images you can take and store.

(Continue) Simply save the pictures you took in a hard drive and bring it to a

photo shop for an outcome of your pictures!
