Each digital camera has a set of microprocessors which control camera’s sensor, buffer, LCD, autofocus, etc. These microprocessors are also controlled by “firmware”, which is software stored in the Read Only Memory (ROM) of the camera. In order to enhance performance and/or add new features, most of the cameras allow the firmware to be upgraded. […]

Fill Factor

Fill factor, in the context of solar cell technology, is defined as the ratio (given as percent) of the actual maximum obtainable power, (Vmp x Jmp) to the theoretical (not actually obtainable) power. In the context of photography and cameras, the fill factor indicates the size of the light sensitive photodiode relative to the surface […]


A digital camera doesn’t store only information about the pixels of the image, it also stores information about the date and time a picture was taken, aperture, shutterspeed, ISO and many other camera settings. All these information, also called “metadata” are stored in a header. One of the most used type of header is EXIF […]

Effective Pixels

As we look at a digital image, we must understand that the number of pixels is not the same thing with the number of sensor pixels measurements that were used to produce that image. In conventional sensors, each pixel has one photodiode which corresponds with one pixel in the image. A conventional sensor in, for […]


We talk about connectivity, at a digital camera, when we want to refer at the way that other devices can be connected, so that transfer, viewing or printing of images can take place. We also need connectivity to use the camera for remote capture. Image transfer To be able to transfer images to your computer, […]
