When light falls upon the particular object , it is reflected back after striking through the object. The rays of light when passed through the lens of eye , form a particular angle , and the image is formed on the retina which is the back side of the wall. The image that is formed is inverted.
Digital Imaging Integrated Circuit
In Digital Photography ISO measures the sensitivity of the image sensor. The same principles apply as in film photography – the lower the number the less sensitive your camera is to light and the finer the grain. By choosing a higher ISO you can use a faster shutter speed to freeze the movement.
ISP(Image Signal Processor ) An image signal processor, also called image processing engine, is a specialized digital signal processor used for image processing in digital cameras, mobile phones or other devices. THine's ISP is an image processing engine for a digital camera.
Tuning (an ISP) Adjusting an image signal processor to optimize performance. The most common principal tasks of an ISP are demosaicing (interpolation), autofocus (and other automated functions), noise reduction, and lens corrections.
digital single-lens reflex
This is really a naming convention that Canon has adopted for its cameras. The “D” stands for digital since canon used to make SLRs way before dSLRs came into existence. The series however denotes specific differences. XXD (60D, 70D) are close to professional dSLRs with superior processor and sensor.
Defining a DSLR
In the most literal sense, a DSLR camera is a digital single-lens reflex camera. The advantage of this design, compared to that of a mirrorless or point-and-shoot camera, is that you can see, in real-time, the exact scene you're going to capture via the optical viewfinder.A DSLR camera is a SLR camera modified to work with a digital sensor instead of a film. Each has it's advantages, and most people uses the DSLR because it's quality is on par with the SLR with a good film. The DSLR is better for most people.
You should buy a DSLR because you have an interest in taking pictures your current camera cannot (long exposures, shallow depth of field, extreme low light). It's time to get a DSLR when you are ready to move your camera out of "auto" and into full manual so that you are thinking through every image you take.

DSLR: DSLRs use APS-C or full-frame sensors. Mirrorless: They typically use the same sensors, but there are also smaller formats for even smaller cameras.
Mirrorless cameras have the advantage of usually being lighter, more compact, faster and better for video; but that comes at the cost of access to fewer lenses and accessories. DSLRs have the advantage in lens selection and an optical viewfinder that works better in low light, but they are more complex and bulkier.
The 10 best DSLRs
- Nikon D850. Quite possibly the best camera in the world.
- Canon EOS 7D Mark II. Lots of appealing features makes the 7D Mark II an obvious choice for enthusiasts who shoot a bit of everything.
- Nikon D500.
- Nikon D7500.
- Canon EOS 800D.
- Canon EOS 90D.
- Canon EOS 250D.
- Nikon D5600.
DSLR stands for digital single-lens reflex. In simple words, it is a digital camera which uses mirror to direct the light from the lens to viewfinder. The viewfinder is a hole which lies on the back of the camera and used to preview the image before you capture it. DSLR camera comes with interchangeable lenses.
Different Types of Cameras
- Compact Cameras.
- DSLR Cameras.
- Mirrorless Cameras.
- Action (Adventure) Cameras.
- 360 Cameras.
- Medium Format Cameras.
- Traditional Film Cameras.
On the whole SLR lenses work on digital cameras both DSLR and mirrorless if they can be made to fit the right geometry with adapters or have compatible flanges. But the auto focus and sensing of and setting the diaphragm won't be there (manual) and the lens ID will not be known.
So, here is a list of advantages DSLR cameras have over point and shoots:
- Ability to change lenses and depth of field.
- Overall better image quality.
- Shutter and focus speeds.
- You see what you shoot.
- Lots of ways to control the camera.

A digital signal processor (DSP) is a specialized microprocessor (or a SIP block) chip, with its architecture optimized for the operational needs of digital signal processing. The goal of a DSP is usually to measure, filter or compress continuous real-world analog signals.
A digital signal processor takes a real world signal (audio, pressure, images) that have been digitized through an analog to digital converter And mathematical manipulates them. The manipulation is done through programming and is based on the architecture of the processor.
