Abstract: Provided are an image enhancement method and system. The method comprises: acquiring an input brightness value, and calculating a logarithmic mean value of the input brightness value; processing the input image based on a Retinex image enhancement algorithm to obtain a first brightness gain value; according to the logarithmic mean value of the input brightness value, making a calculation to obtain a brightness gain control factor; according to the brightness gain control factor and the first brightness gain value, making a calculation to obtain a second brightness gain value; and enhancing the input image according to the second brightness gain value to obtain an output image. In the present application, a Retinex image enhancement algorithm is used to enhance an input image; and by using a brightness gain control factor, when the brightness of an image is low, a first brightness gain value will be largely compressed, and when the brightness of the image is high, the first brightness gain value is less compressed, so that the brightness gain of a dark image is lessened. The brightness of an output image is effectively controlled, so that the brightness of the output image can not only be raised, but also can satisfy a real environment.

Title: A system and method for increasing optical power in an RF over fibre link
Inventor: IAN FLINT
IPC: H04B10/2575
Filed: 2020-08-13
Abstract: This application is concerned with transmitting a microwave radio frequency signal over an optical link, which in the prior art is referred to as Radio-over-fibre (RoF) transmission. The invention aims to improve the signal-to-noise ratio by increasing optical power to compensate for shot noise. This is achieved by using multiple lasers. In embodiments, the lasers have different wavelengths and outputs from the wavelengths are multiplexed 11 to produce a multiplexed optical beam. In embodiments, a modulator 13 modulates an RF signal 100 onto the multiplexed optical beam and one or more photodiode receivers 14, 14A receive the modulated multiplexed beam and output the RF signal. In other embodiments, the multiplexed optical beam is demultiplexed (53A, Fig. 5) into multiple beams, which are each passed to a respective modulator (54A, 54B, Fig. 5). One embodiment is concerned with determining a requisite optical power to achieve a predetermined signal to shot noise ratio, and consequently the number of lasers required. The number of modulators and photodiode receivers are then determined, ensuring there is no overloading. Each photodiode receiver may be a balanced photodiode receiver.
