Digital camera interpolation explained

Written by Jakob Jelling

In a device such as a digital camera it is very important to understandrepparttar very basic aspects ofrepparttar 116096 device so as to properly operate it and give itrepparttar 116097 due respect it deserves. Such a topic is interpolation! These are accessories that helprepparttar 116098 digital camera to performrepparttar 116099 technologically advanced features that it is capable of. In extreme explanatory and simple terms it can be summed up as that interpolation refers to software programs that can effectively enlarge image resolution beyondrepparttar 116100 actual resolution by adding extra pixels using complex mathematic calculations. Now, this is a feature that can be absolutely useful in providing a good success to a user.

Looking intorepparttar 116101 technical aspects it can be stated that interpolation is a technique whererepparttar 116102 spatial resolution of an image is increased from its original size to a higher or larger resolution. The spatial resolution of an image is simply its horizontal x vertical pixel count. For example 1600 x 1200. Again getting into further intricate details it can be stated that there are two techniques of interpolation commonly used, they are software and hardware. Again software interpolation can be performed on a digital image using a one of a number of image editing programs such as PhotoShop. This is often termed as resizing and is done with a computer, performed on an image file from a digital camera that already exists in a file format such as JPG. Hardware interpolation involvesrepparttar 116103 resizing of an image, but it differs from software interpolation in thatrepparttar 116104 image is resized algorithmically insiderepparttar 116105 camera duringrepparttar 116106 image processing sequence and beforerepparttar 116107 image has been saved as a JPG image file.

Building a Wood Ladder

Written by Dave Markel

This is a simple project that should only take a couple of hours to complete.

Supplies: You will need 2 - 12' 2x4's (uprights) 2 - 8' 2x3's (rungs) Exterior wood glue 36 - 2-1/2" Deck Screws

Tools: 4 Clamps Measuring Tape Square Pencil Circular Saw Drill with countersink and screw bit Hammer Chisel

Start by clampingrepparttar two 12' - 2x4's together withrepparttar 116095 top edge and ends flush. Stand them on edge. The rungs are notched intorepparttar 116096 2x4 upright 1-1/8" so we need to mark out notches. The top and bottom rungs are 8" fromrepparttar 116097 ends, place a mark at 8". This isrepparttar 116098 top ofrepparttar 116099 upper rung andrepparttar 116100 bottom ofrepparttar 116101 lower one. Offset these marks 2-1/2" (the width ofrepparttar 116102 2x3 rungs).

Now measure out forrepparttar 116103 rest ofrepparttar 116104 rungs. Lay your tape measure onrepparttar 116105 8" mark made earlier and measure 16" increments. These marks representrepparttar 116106 center ofrepparttar 116107 intermediate rungs. Offset these marks 1-1/4" on either side.

Using your square, square offrepparttar 116108 marks you have just made downrepparttar 116109 face ofrepparttar 116110 2x4 uprights 1-1/8" deep. Square your marks acrossrepparttar 116111 top edge ofrepparttar 116112 uprights as well.

Now it is time to cutrepparttar 116113 notches. Setrepparttar 116114 depth of your circular saw to 1-1/8". Start by makingrepparttar 116115 cheek cuts ofrepparttar 116116 notch then proceed to make a series of cuts about a 1/4" apart throughrepparttar 116117 rest ofrepparttar 116118 notch. Do this for allrepparttar 116119 notches.
