What does HDR mean?

hdr stands for High Dynamic Range Imaging and, in computer graphics and cinematography, is a set of techniques used to achieve a larger exposure dynamic range than ordinary digital image techniques; The goal of high dynamic range imaging is to correctly represent the wide range of brightness in the real world, from direct sunlight to the darkest shadows.

HDR mode is an abbreviation of High Dynamic Range, which means high dynamic range imaging in Chinese. Dynamic range refers to the maximum that a camera can record when capturing an imageThe ratio between dark and brightest tones. The greater dynamic range means the camera is able to capture images across a wider range of brightness, allowing for scenes with higher light contrast while preserving detail in both highlighted and shaded areas.

HDR refers to the High-Dynamic Range (HDR) image, which can provide more Dynamic Range and image details than ordinary images. The LDR image corresponding to the best details of each exposure time is used to synthesize the final HDR image. It can better reflect the visual effects of the real environment. Open method:Co., Ltd. developed a compatible USB PD, QC and AFC protocol Sink controller. The LDR6328S draws power from an adapter that supports USB PD, QC, and AFC protocols, and then supplies power to the device. For example, adapters can be configured to output the required power to power wireless charger devices. The LDR6328S is also compatible with traditional USB power adapters.

PD protocol charger is different from the previous USB-A QC charger, its default is no voltage output,Only when the load side is detected to have a pull-down output 5V, and then through communication with the power chip, the output required fast charging voltage is 9V, 12V, 15V, 20V. PD protocol refers to the USB-PD protocol, is a fast charge protocol proposed by the USB-IF organization, the full name of USBPowerDelivery, can reach 100W.

According to the PD protocol query, the PD protocol charger is different from the previous USB-A QC charger, its default is no voltage output, only the load side is detected to have a pull-downOutput 5V, and then through communication with the power chip, output the required fast charging voltage, such as 9V, 12V, 15V, 20V.

What are the characteristics of embedded systems?

Highly integrated real-time response capability, low power consumption and strong customization. High system stability. The software code is demanding. Scalability and modular design. Strong integration with other technologies. Strong hardware support capability. Strong software support capability. Has a wide range of application field adaptability.

is very specificThe advantage of embedded operating system is that it is highly personalized, the combination of software system and hardware is very close, and it is generally necessary to transplant the system for hardware, even in the same brand and the same series of products, it needs to be modified according to the changes and increases and decreases of the system hardware. At the same time, for different tasks, it is often necessary to make large changes to the system, and the compilation and download of the program should be combined with the system.

Embedded system is a special type of computer system, its main characteristic is that it has strict functional limitations and resource limitations. The main characteristics of embedded systems are as follows: Miniaturization: Embedded systems are usuallyA small, low-power hardware platform is required. This makes them suitable for many different application areas, such as medical devices, vehicles, smart homes, and more. Real-time: The embedded system must be able to complete its task within a specified time.

The operating environment varies greatly. Embedded systems are everywhere, but the operating environment is very different, can be run on an airplane, in the ice and snow poles, in the hot car, requiring a constant temperature laboratory, especially in the harsh environment or sudden power failure, the system is still required to work normally. Less resources than common PC systems.

The main features are: the system kernel is small. Embedded systems are generally used in small electronic devices, resources are relatively limited, so the kernel is smaller than the traditional operating system. Strong specificity. Embedded system is personalized, in which the software system and hardware are closely combined, the general hardware system to be transplanted, even if the same brand, the same series of products also need to be modified according to the changes and changes in the system hardware.

Embedded system features are rich and diverse, designed to meet specific application requirements, to provide high performance and stability. The following are the key characteristics of embedded systems: Tailoring: EmbeddedThe system supports an open and scalable architecture, which can be flexibly adjusted according to actual needs to provide customized solutions.
