What are the camera chip models? Camera chip model summary

The camera mainly includes a lens, a CCD image sensor, a pre-amplifier, an AGC, an A/D, a sync signal generator, a CCD driver, an image signal forming circuit, a D/A conversion circuit, and a power supply circuit.

The working principle of the camera is: the object reflects light, spread to the lens, the lens is focused on the CCD chip, the CCD accumulates the corresponding charge according to the strength of the light, after periodical discharge, produces an electrical signal that represents a picture frame, After pre-amplifier circuit amplification and AGC automatic gain control, the digital signal is processed by the image processing chip, so the analog to digital signal processing IC (DSP). The sync signal generator mainly generates a synchronous clock signal (which is performed by a crystal oscillation circuit), that is, generates vertical and horizontal scanning drive signals to the image processing IC. Then, a standard composite video signal is output through the output terminal via the digital-to-analog conversion circuit. This standard video signal is the same as the video output of home video recorders, VCD players, and home video cameras, so it can also be recorded or viewed on television. Image digital signal processing is mainly SONIX (Song Han) and VIMICRO (Star Micro).

HY7131E: A sensor for PC cameras released by Hyundai Corporation. It is the best product in the current camera market. At present, Hyundai has discontinued production. Only some large camera manufacturers have inventory, if they can buy it now. To such products, the speed and picture quality will be quite good.

HY7131R: An alternative to Hyundai's HY7131E. As far as the current camera performance is concerned, the application of current product drivers is not as effective as HY7131E, but the price/performance ratio is better, and Micro360 can be purchased selectively: it is a good sensor manufactured by Taiwan Micron. , in the drive with the performance and picture quality is not bad, the current market is a large proportion of cameras are equipped with this chip, in the absence of HY7131 products, it is recommended to buy.

At present, there are many DSP models and main parameters used in the camera [except for special labeling, all support hardware 350,000 pixels] VIMICRO301P: In the field of cameras, it is a very good chip in China's chip industry, and it is also quite high in the world. The reputation is the only chip with the most powerful color reproduction and fast transmission. The mainstream cameras use this chip!

SUNPLUS 561: This chip is a hardware chip with 100,000 pixels. After software interpolation, it can still reach 300,000 pixels. It is the most mainstream match of the 300,000-pixel camera on the market. It is worth mentioning that he is a single chip product solution, sensors and DSP are integrated into one chip, so the price is quite high!

VIMICRO301L: An alternative product to the 301P, which is an optimized product under control costs. Although there are few products on the market today, it is believed that the success and experience of the 301P product from ChinaStar Microelectronics Co., Ltd. must be quite effective. Not bad.

EM2800/2710: This chip is a hardware 1.3 megapixel DSP of 禾 Rhea, EM2800 is mainly used as a TV card acquisition chip, but there are also some large camera manufacturers in China to make him a camera product, such product speed It is about twice as much as a normal camera. EM2710 is mainly used as a camera product. Its product performance is equivalent to the EM2800 in the application of the camera. Both chips support high-speed USB2.0 interface at the same time. Under the computer with good performance, the effect and speed of the product will be very good!

Sonics102P: One of Taiwan's famous dsp, its product features in the image quality is clear, color and color performance is better, but the relative speed compared to similar products, the speed is slightly superior, a small part of the market portable small camera, also With this chip!
