Digital Cameras beginner guide
Digital Cameras - A beginner's guide by Bob Atkins, 2003

Digital Camera Basics - A primer Digital cameras are confusing to a lot of new users. In this basic guide to digital camera technology we hope to try to give digital beginners at least some basis to use in deciding which digital camera is appropriate for them. When shopping for a digital camera it's at least good to know what the basic terms like white balance, pixel, ppi and dpi mean and how they affect image and print quality. It's also important to know the difference between things like optical zoom and digital zoom as well as the advantages and disadvantages between storage formats such as Compact Flash (CF), Microdrives, Sony Memory Stick, Secure Digital (SD), Multimedia and camera interface technologies such as USB 1.1, USB 2.0 and Firewire IEEE 1394.
Pixels A pixel is a contraction if the term PIcture ELement. Digital images are made up of small squares, just like a tile mosaic on your kitchen or bathroom wall. Though a digital photograph looks smooth and continuous just like a regular photograph, it's actually composed of millions of tiny squares as shown below.

Each pixel in the image has a numerical value of between 0 and 255 and is made up of three color channels. So for example a pixel could be 37-red, 76-green and 125-blue and it would then look like this . If it was 162-red, 27-green and 12-blue, it would look like this . There are over 16 million possible combinations using this scheme and each one represents a different color. Computer savvy readers will note that each color in this scheme can be represented by an 8-bit number (byte), so the color of each pixel is defined by three color bytes. This scheme can be expanded, for example to use 16-bits (two 8-bit bytes) for each color. images using three 8-bit values are sometimes called 24-bit color images. images using three 12-bit values for color definition are called 36-bit color images, and those using three 16-bit values are called 48-bit color images.

Pixel Count One of the main ways that manufacturers categorize their digital cameras is in terms of pixel count. What this is is the number of individual pixels that go into making each image. Today this number varies between 1 million (1 Megapixel) to around 14 million (14 Megapixels). A million pixels is abbreviated to MP, so a 1MP camera has 1 million pixels and a 3MP camera has 3 million pixels. Currently most popular consumer digital cameras have between 2MP and 5MP. A 3MP camera can make excellent 4"x6" prints and very good 5"x7" prints. If you intend to make lots of 8"x10" prints, then perhaps a 4MP or 5MP camera would be a better choice. Sometimes two numbers are given, total pixels and effective pixels. Total pixels count every pixel on the sensor surface. Usually the very edge pixels aren't used in the final image. Effective pixels are the number of pixels actually used in the image after the edge pixels have been dropped.

Aspect Ratio The aspect ratio of a camera is the ratio of the length of the sides of the images. For example, a traditional 35mm film frame is approximately 36mm wide and 24mm HIGH. This has an aspect ratio of 36:24, which can equally well be expressed as 3:2. Some digicams use the same aspect ratio for their digital images. For example most digital SLR (single lens reflex) cameras have a 3:2 aspect ratio. However, video monitors typically use a 4:3 aspect ratio. For example a monitor with a 800x600 display has a 4:3 aspect ratio. With this in mind, most consumer level digicams use a 4:3 aspect ratio for their images.
Sensor Size The size of the digital sensor element (which is equivalent to the size of the negative for film cameras) is pretty small in all consumer digicams - typically around the size of a fingernail (and a small fingernail at that!). As I said above, a 35mm film frame is 24mm high by 36mm wide but most digital cameras use sensors very much smaller than this. Here are some typical digicam sensor sizes. The "name" of the sensor is based on specification for old TV tubes used in the 1950s. Nobody is quite sure why it's being used for modern digital sensors since the "sizes" don't really relate in any consistent way to the actual physical size of the sensor. However these names are widely used, so it's best to know what they are. They are often listed in digital camera spec sheets.

What will be the pixel or size of tarpaulin when i used gimp?


I don't know if this will help and all and I had to search up what tarpaulin and a few things came up and I honestly dont know how big you wan't it but Im going to give it a try

1 pixel = 0.0008680556 feet

But if im wrong I would just search it up on google for converters, Im sorry im not much help even though I use gimp daily

Is audio output (from main ic) is imputed in utc2003 audio amplifier ic?


Is the UTC2003 IC your main IC?
You can't find inputs or output of this IC?
This IC is power Operational Amplifier simply. It has TWO inputs noninverted = pin 1 and inverted = pin 2 and ONE output = pin 4. Pin 3 is ground and pin 5 is supply voltage. It's simple as the rake! What is your problem? Sorry for my rusty English...

Error code


Hello,

DS00001 error is a TWAIN driver error which explains the input value is set outside the range.
Cause:A value exceeding the range allowed for an input item was input.
Resolution: Input a value within the allowed range. Refer to the input item or the image scanner specification for the range.

Hope the above information is helpful.

Thanks & regrads,

Recently I found one balck spot on my picture, I dont know whay the black spot is coming. I am having a Nikkon D90 18-105 lens.


The black spot can be from one or two sources. The first, is a called a stuck or hot pixel. Your camera's sensor has 12.9 million pixels (12.3 million are used for the image). Many times, a hot or stuck pixel is a bright color - red, yellow, green, etc. It can be any color however. Dark or black pixels can also be called dead pixels as they look like they're "off." Regardless of which your camera suffers, it will not respond to light projected on the sensor by the lens. You'll have to have manually edit the pixel in each image, or return to Nikon for sensor replacement. Nikon used to perform a mapping out of the pixel, but it seems that they don't do this any longer. A sensor replacement can cost in the hundreds of dollars.

The second source, is dust on the sensor. A pixel(s) blocked by dust will show up in each picture, but will appear to be more in focus in some images than others - depending on the aperture value of the camera when the exposure was made. A stuck pixel usually has a very definite edge on all images regardless of aperture setting. A simple, careful wet cleaning of the sensor with a product designed specifically for the job can solve this problem pretty quickly.

Here's a video for wet sensor cleaning from Youtube There are others here too. I hope this was helpful & good luck!

Pixel shader


A pixel shader computes color and other attributes of each pixel. Pixel shaders range from always outputting the same color, to applying a lighting value, to doing bump mapping, shadows, specular highlights, translucency and other phenomena. A pixel shader alone cannot produce very complex effects, because it operates only on a single pixel, without knowledge of a scene's geometry or of neighboring pixels. A pixel shader is a computation kernel function. Pixel shaders can alter the depth of the pixel (for Z-buffering), or output more than one color if multiple render targets are active

My new Samsung LE32R88BD was showing a pixellated picture on movement, but it filled the entire screen. Since switching my Virgin box through HDMI, the picture is less pixellated but I cant get the picture...


I did some reading on the net, try to "calibrate the screen". Try set the input to 1080i, then run the thx optimiser to give you a starting point, then try a bluray with a bright image.

Keep replaying the same chapter and try raising and lowering different settings. you may find that your brightness is set way too high and after dropping it from 90 to 29, you may find that detail will have crept into the image. Try giving the colours a boost as well.

The detail in HD is very subtle, and having a properly calibrated screen will make all the difference. So to answer your question: set your input to 1080i, make sure your HDMI is outputing RGB and start tweaking that screen!
