The Difference Between an SLR Camera and a Digital Camera

Sensitive area: SLR camera imaging is purer The photosensitive area of ​​a digital camera is much smaller than that of an SLR. For example, in SLR cameras, the size of the APS-C frame is about 24*16mm, and the full-frame size is about 35*23.5mm. The size of the photosensitive element of a digital camera is generally equivalent to the size of a fingernail. However, due to the disadvantage of the photosensitive area, the digital camera pixel The higher the density, the more impurities in the image. Photoreceptor time-consuming: digital cameras work longer The photoreceptor of a digital camera works during the viewfinder, while the photoreceptor of an SLR camera (CCD or CMOS) works during shooting. Compared with SLR cameras, the working time is shorter, and the picture quality is better. Price: SLR prices are higher There is still a certain gap between the prices of digital cameras and SLR cameras. Because SLR image processing chips are more capable, the response of SLR machines is much f

Things to Consider When Choosing Bluetooth Headsets

 With the development of Bluetooth headset technology, more and more terms are flooded with it, which brings a lot of trouble to the purchase. I hope this article can clear the fog and let more people understand whether these parameters are useful to find a Bluetooth headset that suits them. 1. Brand (1)Bluetooth headsets derived from mobile phone manufacturers The brand is well-known and has a large fan base. Such as Apple, Huawei (2)Traditional acoustic equipment manufacturers, mostly international brands, with technology accumulation, are relatively mature. Such as: SONY, JBL, Audio-Technica ( 3) Newly emerging domestic brands Rely on high-cost performance to highlight products, such as 1more, display 2. Sound quality Common Bluetooth headset evaluations will use artificial ears to obtain the frequency response curve of the headset. The disadvantage is that the ear canal structure of real people is different, so artificial ears cannot represent the public’s hearing experience. In te

Interpret the development trend of consumer electronics

 The Nielsen survey shows that 44% of consumers worldwide say that their grocery spending has increased in the past five years. This is the uniformity and commonality presented on a global scale. In addition to groceries, the categories that consumers spent the most in the past five years are technology and communications (38%), education (34%), travel (33%), and healthcare (32%). Rising spending on technology and communications is a common phenomenon worldwide, while spending on education, tourism, and medical care is regional. The categories that consumers are willing to pay high prices include consumer electronics (42%), clothing/shoes (40%), cosmetics (31%), dairy products (30%), and meat/seafood (29%). With the development of society and the gradual maturity of technology, consumer electronic products have gradually changed from high-end consumer goods to daily necessities. They have penetrated the daily lives of ordinary consumers. The design of consumer electronic products shoul
