Cell Phone Cameras
By Jakob Jelling, Fri Dec 9th

A lot of myths exist regarding as to whether the cell phonecameras are any good or not. The fact that people require toadmit that these are also digital and theyexhibit the same facilities irrespective of the fact that theirsizes are much smaller and their functionalities are curtaileddue to this particular reason. Hence some introspection needs tobe done regarding the digital and cell phones in theirjoint venture together in the technological world!

Looking back into the initial stages of development theavailability of low-cost, low-power CMOS imaging modules helpedto charge up the popular craze camera enabled cell phones intoday's world that primitively began in Japan. That proved to becontagious for the rest of the world. From young students toeven busy business people avidly annals photos of colleagues andwhatever else passes in front of their phones. The popularityhas touched sky high and the reason being the good quality thatpeople seek at grass root level endeavors of photography.Americans have the urge to seek betterment in these areas also.They go about to seek cool new digital camera phones that allhave VGA resolution 640 x 480 pixels. This is considered a safebet that this phone is the most expensive model.

Much of a kind of ignorance exists apart from all this regardingthe cell phones and it crops from the fact that nobenchmarks exist for objectively comparing picture quality inimage sensors, camera modules, or end products. The helplessconsumers thus have to rely upon advertisements to tell themmuch. Yet this is not a correct way to knowing a technicaldevice. Considering the technological portion it can be saidhere that in the cell phone some of the VGA handsetsoffer fairly good image quality. When you consider that theresolution comes from an imaging module that measures only 6 mmsquare, its actually pretty amazing quality.

That squareincludes an imaging chip, a digital signal processor (DSP) thatsupports the VGA format, and a double lens that's packaged in alight-tight module. Finding room for this module is easy. Plus,power consumption is low because the imaging chip is CMOS.

Considering the further improvements in the cell phone cameratechnology it can be stated here that some cell phones haveincorporated conventional CCD imaging units that are still usedin most digital today. These devices require highvoltage and a bigger a battery. As a result, CMOS has taken overin VGA-resolution applications. It provides increasingly goodimage quality. All this discussion shows the variousachievements in the technology. However it must be stated herethat the cell phone are really good but they are nothingcompared to the actual digital cameras. The sole reason beingthat they are much larger and contain far more features. It mustbe admitted here that such comparison is irrelevant because theyare definitely two separate areas of work in spite of the factthat they are both digital cameras. Yet they are diverse in 100%of all their aspects. Hence the comparison is irrelevant.

Considering all the important points discussed in the abovelines regarding the various areas of the cell phone digitalcameras it comes out to be something that is worth appreciation.Leaving aside all comparisons they cell phone aredigital that are certainly good in their areas ofapplications and mass acceptance and popularity would some daymake them as advanced as their pioneer professional digitalcameras.
