Chapter 422 There will be bread, there will be milk, just wait!
Tinkering with digital cameras these days is a joke.
Take the most common 35mm film as an example; converted to a resolution, it's at least around 15 megapixels. However, due to the influence of the film's silver halide, the quality varies; high-quality film generally has over 20 million pixels.
A digital camera needs at least 300,000 pixels to be acceptable, and even then, it might not be able to print out the image on a home printer.
Before Xing Baohua wore it, the mainstream mobile phones had cameras with around 20-30 megapixels. Of course, there were also those claiming 60-100 megapixels. Those were the result of multiple cameras stacked together, with no single camera exceeding 100 megapixels.
What does 100 million pixels mean? It's like taking a picture of a stadium where a game is in progress from a kilometer away, and when you zoom in, you can see the face of each spectator without losing frame rate.
Normally, 20 megapixels is enough to take a very clear picture. But home printing equipment can't achieve the same effect.
This was in the late 1980s, and the most crucial thing was storage.
With current technology, electronic light sensors can be used to create core devices with 20-megapixel resolution. However, they are bulky and consume a lot of power.
The key point is that you also need to equip this thing with a hard drive array enclosure.
Xing Baohua develops civilian equipment, emphasizing compactness, flexibility, convenience, and ease of use.
There's no such thing as building something bigger and bigger.
The camera in the lab can reach 100,000 pixels. Although it's an experimental device, a one-minute video recording is approximately 2.8 MB.
This is a compressed video created through technical compression; it's only passable when displayed on a screen.
Using it as a surveillance camera is too much of a strain on the eyes.
Although digital cameras are being developed, the only problem is that the hardware can't keep up, but we can't stop now.
Therefore, Xing Baohua was asked to come up with a way to generate temporary profits.
Without the aid of large storage devices or online video decoding equipment, 100,000 pixels is sufficient. Back in the day, webcams in internet cafes were just a blurry black shadow, and that was it.
Anyway, that's the gist of it. Even with unclear cassette tapes, we just persevered step by step. Back then, there was nowhere to vent our frustrations.
Xing Baohua developed this device for video conferencing used in company-level meetings.
This product won't be produced in large quantities; it's just an addition to his product catalog.
Is the product any good? Definitely not. It's limited by your internet speed and will lag terribly.
The only solution is for businesses to increase their network speed or for internal LAN use. To address this, Xing Baohua had people specifically draft and resolve various protocol issues.
With the current 56K network speed, the only solution to the smoothness issue is to continuously compress the video. This not only requires high network speed but also has limitations based on the existing network conditions.
We need to equip ourselves with devices specifically designed for this type of conference-level video hardware to solve the problem.
Another video phone doorbell.
There's a camera and a talkie outside the door. Inside, there's the talkie and a monitor. This thing doesn't have high hardware requirements; it doesn't need storage, so it basically functions like a peephole.
Xing Baohua prepared two types of monitors: a 7-inch fluorescent screen monitor and a 7-inch LCD monitor.
The only difference is the price.
Since color LCDs have not yet been fully developed, only black and white LCDs can be used.
I thought it wouldn't be so complicated, so I just made both models in black and white, which would be more convenient.
The last one is the monitoring system.
Let's not release the 100,000-pixel camera yet, but we can research the next generation, such as 300,000 pixels, which could be commercially available.
The key is the recording equipment; current surveillance equipment uses cassette tapes, which are video recorders.
The equipment is expensive, and so are the cassette tapes; a single cassette tape can only record for about an hour. Currently, the wholesale price of a cassette tape is around 50-60 yuan.
This calculation shows that the cost of the cassette tape is also high. Although more than a hundred tapes can be used for a 48-hour or 72-hour cycle, the time is still short.
Xing Baohua's idea was a VCD burning device.
Sony and Panasonic release multi-disc CD players, right? They use that multi-disc technology to hold CDs. VCDs typically have a capacity of 600-700MB. Due to technical limitations, writing to them is cumbersome; they can only read files from the device itself.
Unlike a hard drive, it cannot be easily modified or deleted. Therefore, once written, it is generally not changed.
Using this principle, Xing Baohua simply burned the video into the file, and could then play it when needed.
A single disc can record approximately 600 minutes, or about 10 hours, depending on the video format.
However, CDs are much cheaper than videotapes. After one cycle, a CD can be erased and rewritten, up to three or four times. The CD will be damaged due to friction and scratches.
For enterprise-level applications with multiple cameras, CDs are more cost-effective.
Therefore, VCD-level monitoring systems have also been included in the research and development project.
Xing Baohua came out of the laboratory that day, turned the corner and went to the rice factory production workshop to take a look. He happened to run into Liu Quan, the production manager, who was also strolling around inspecting the work.
Since Xing Baohua handed over power to the rice union, he has rarely come here. This time, he came mainly to conduct a spot check.
Liu Quan accompanied him through several workshops, and then the two stood outside the workshop doors smoking and chatting.
Liu Quan told Xing Baohua some gossip: he heard from a technician at the machinery factory that the deputy factory director had been beaten up recently.
"Deputy Factory Director Hou?"
"That kid Hou Liwei is now the executive deputy factory director, just one step away," Liu Quan said with a smile.
Why is he laughing when others have promoted him?
Xing Baohua muttered to himself, "This kid's risen incredibly fast! He's young and promising!"
