Abstract: The disclosure relates to an image tone adjustment method, an apparatus thereof, and a computer-readable storage medium. The method includes: fitting overlapping areas to obtain a first correction parameter and a second correction parameter, performing interpolation on each pixel of the target image to obtain a corresponding correction parameter, correcting the target image according to the corresponding correction parameters; fitting an overlapping area between the corrected target image and the first image, and an overlapping area between the corrected target image and the second image to obtain a first RGB three-channel linear transformation parameter and a second RGB three-channel linear transformation parameter, performing linear interpolation on each pixel of the corrected target image to obtain a corresponding RGB three-channel linear transformation parameter, and transforming the corrected target image.

Abstract: The present invention relates to a method of manufacturing a micro reactor device that includes a tubular reactor (1) as a flow path, for allowing reaction species to react in the reactor (1). The micro reactor device is manufactured by forming a particle layer (2) on an inner wall of the reactor (1). The particle layer (2) can be formed by causing a dispersion liquid of particles to flow through the reactor (1) and drying. In this way, it is possible to provide a method of manufacturing a micro reactor device having an inner wall modified so that the reaction species can react more efficiently, and to provide the micro reactor device.
