A digital image is the illustration of a two-dimensional image with a finite set of digital values that are known as picture elements or pixels. It can be created by a digital camera, scanners, airborne radar, seismographic profiling, coordinate-measuring machines and others, http://www.wordiq.com/definition/Digital_image
Not long ago, only some families owned a camera. Today people have a variety of digital options to capture images. These are video cameras, laptops, handheld camera phones and others. People use technology for different occupational purposes such as work, play, entertainment, personal and other daily activities. Images can be distributed, manipulated and used with a purpose.
My digital camera is mainly used in the family. It has a lens system and it has a variety of functions such as; low light, iso-speed, self-time, digital and optical 3 x zoom, delete button, red eye, USB port, language, mode (day and night) flash, date & time, blink detection and other functions that I have not discovered yet. It is very easy to use once you are familiar with it. The photos that are taken can be transferred onto the lap top via a USB cable. The computer provides instructions when downloading the images. Apparently there are some important pieces of information to know when you buy a camera. If you follow this link you can find some useful information http://www.youtube.com/watch?v=CpWtq-haaCQ
The video camera that I have is very simple to use as well. However when it comes to transferring movies on the computer or CD disks, I find it very challenging. This camera was gifted and was brought to me from Europe. I am trying to blame the software being different over there to New Zealand. Now I am going to watch some tutorials, which could help me with my video camera that I have locked up in one of my wardrobes for the last two years. If you are interested to see how a tutorial teaches you to use a camera, you can view this link as well http://www.youtube.com/watch?v=EviEjddoeDk
Another electronic device that I am comfortable using is a cell phone with a built in camera. Most cell phones have this type of set up. By pushing only a button on the camera side, photos are taken. Furthermore, connecting it to the computer via a USB cable, photos can be loaded and printed when I want. Here is a site which offers a wide range of cell phones with built in camera option http://www.1800mobiles.com/camera-cell-phones.html
An interesting electronic device that has digital imaging is a cell phone, watch and camera all in one http://www.geekalerts.com/cell-phone-watch-with-camera-and-bluetooth/
Today’s digital camera technology has advantages and disadvantages. An image can be obtained very fast, can be modified easily and stored with a click of few buttons. However, this data can be easily lost if a computer or other devices that store the images are damaged. Software can also be out of date and images are difficult to access.
Ethical issues can arise, when people use digital images inappropriately. The issues can arise when people’s privacy, ownership or informed consent for recording and distributing of images are not seriously taken in consideration and disturbing images are published in the media, in schools or in day to day life. One example is the paparazzi, who are capturing images that can produce disturbance in some people’s personal life http://www.bing.com/images/search?q=paparazi++unethical+images&view=detail&id=78755EAACF55E1B831A946671DB3098CE009FCCC&first=1&FORM=IDFRIR
There are debates on whether it is ethical or not to use “nanny cameras” as this is believed to be a parent’s right. http://www.azcentral.com/families/articles/0119videotaping19.html?&wired
The occupational therapist has to take in consideration the way digital images are used. The client and his/her family have to be comfortable with the context in which images are used. For example, if an OT wants to record the way a client makes a cup of tea, she/he needs to ask for consent. Such a recording can also be uploaded on websites that are intended for the general public. Therefore to exclude any negative repercussions, ethical issues needs to be considered. Occupational therapists use images in some treatment plans to educate their clients. A good example of a digital image is about the correct technique of ”Retrieving Items while Using a Rolling Walker". http://www.youtube.com/watch?v=xcRltltGPqw
