"Thread: What do you mean by, "" 2 megapixel camera interpolated to 4 megapixel ""." If you want good interpolation invest in a copy of photoshop. ...and a camera that produces .raw files. Camera CCD pixels are not the same as display pixels. For a start they have more green pixels than any other colour, which makes sense as the eye is most sensitive to green.

Short Description Superzoom Cameras. Super-zoom digital cameras provide a minimum of 8X zoom with some cameras offering as much as 30X zoom, most offer at least 15X zoom. These offer incredible levels of optical zoom so that you can get close to the action regardless of where you are.his is the scene at 4X zoom, In this case 4X is 56mm which is similar to the magnification of the human eye but a much smaller field of view. Example of a 4X Lens. This is the scene at 8X zoom, In this case 8X is 110mm which is slightly more than twice the magnification of the human eye.

- mega-is a … prefix used to describe how  much of them there are (1 million).   If, for instance, a 1 megapixel image is stored with 24-bit color  (8 bits for red, 8 bits for green, and 8 bits for blue), the total  amount of memory required to store it would be 3 megabytes (24  megabits / 8 bits per byte).

Megapixels This is the amount that you eat. Some cameras use all the pixels on the sensor (and wind up with a clean plate) and others only use a portion of the pixels for the photograph. A camera's effective megapixel number is the number of pixels on the sensor that are actually used to capture the photographic image.

How many megapixels do you need? Similarly, if you halve the width of a 12MP photo, to 2,000 x 1,500, the megapixel rating drops to a quarter, or 3MP. As such, the differences between a 4MP, 8MP, 13MP and 41MP photo perhaps aren’t as big as the numbers might suggest.

Is 5.0 megapixels good for a camera phone? Report Abuse. 5 megapixels is good, however, picture quality really comes down to the quality of the sensor, not the megapixels. I read that the camera are pretty good, not as good as a stand alone point and shoot, but for a smartphone on a prepaid carrier, it's probably one of the best you can get. BORED · 4 years ago.

Image Resolution, size, and compression: Resolution refers to the number of pixels in an image. Resolution is sometimes identified by the width and height of the image as well as the total number of pixels in the image. For example, an image that is 2048 pixels wide and 1536 pixels high (2048X1536) contains (multiply) 3,145,728 pixels (or 3.1 Megapixels). You could call it a 2048X1536 or a 3.1 Megapixel image. As the megapixels in the pickup device in your camera increase so does the possible maximum size image you can produce. This means that a 5 megapixel camera is capable of capturing a larger image than a 3 megapixel camera.
