How did digital SLRs and phone cameras change?

How Camera Changing its Generation with time

The importance of digital cameras is nothing new. Until the advent of digital cameras, photography was a luxury, but with the advent of digital cameras, many doors have opened. Digital SLR is the lifeblood of today's photography.

In 1969, George Smith and Willard Boyle invented the Charge Capold device (CCD) at the Bell Laboratory, which became the basis of digital cameras. This device basically works like an integrated circuit, which is mounted on a surface made of silicone. And it contains a large number of light-sensitive substances, on which particles of light reflected from an object are charged and the light is converted into an electrical signal. As a result, a digital copy of the photo is obtained through special technology. No film or negative is required to save the image here. Instead, memory cards are used, which are the daily companion for storing human information in this age.

In 1975, Kodak engineer Steve Sajon made the first digital camera. The 8-pound camera used 0.01 megapixels to take black-and-white pictures and record them on a cassette tape. It took 23 seconds to take a picture, although Kodak did not bring it to market.

In 1986, Kodak invented the first megapixel sensor. And in 1986, Fuji developed their first-generation digital camera, the DS-1P, but they did not market it.

The first digital camera to be sold in the market in 1990 was the DY Cam Model 1, which at the time had a market value of US 600. Then in 1994 Apple introduced their first digital camera Apple Quick Tech.

Now let's come to the world of mobile phone camera. The first camera phone, the Sharp J-SH04, was launched in 2000, and was launched by J Phone, a Japanese mobile phone manufacturer. This phone used a 0.1 megapixel camera. The same year Samsung launched their first camera phone, the SCH-V200.

Nokia launched their first camera phone, the Nokia 7650, in 2002. The 0.3 megapixel phone could take 640X480 color pictures. Three years later, Nokia launched the most acclaimed N-Series 'N90'. It was Nokia's first mobile to use the Carl Zeiss lens. It also had the advantage of making videos. Then came the Nokia N series N93, N95, N82, N86, N8. The N95 is the first to add a 5-megapixel camera, while the N8 is a 12-megapixel one.

Camera phones are slowly gaining popularity. Although at that time the phone cameras were quite weak from the separate digital cameras. Fixed focus lenses, small sensors, limited functionality - despite these problems, phone cameras continue to gain popularity. Mobile photography has been around since the advent of smartphones. The first Android smartphone, the HTC Dream, had a 3.15-megapixel camera with autofocus feature. And the first generation iPhone comes with a 2 megapixel camera.

Many people start hobby photography with the help of smartphones. Smartphone manufacturers are emphasizing the front camera for taking selfies. Maybe smartphone cameras will soon replace DSLRs.

A picture is worth a thousand words. And that's why there is so much need for cameras around the world. From social media to the world of entertainment or news media, the triumph of the camera is everywhere. For some it is just a source of entertainment, for others, it is a tool. History always teaches us to think anew. It has taken a long time to come from the camera obscura to phone camera, but the difference between the camera of 200 years ago and the camera of today is really surprising. The development of technology has never stopped. The development of science and technology is the result of today's modern cameras. Who knows, maybe the camera of the future will be even more wonderful!
