Embodiment Construction

[0054] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be described in detail below. Apparently, the described embodiments are only some of the embodiments of this application, not all of them. Based on the embodiments in the present application, all other implementation manners obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present application.

[0055] Congenital color vision disorder, commonly known as color blindness, is the inability to distinguish various colors or certain colors in the natural spectrum. Color blindness is more common due to congenital factors, and there are far more male patients than female patients. Color blindness is divided into full color blindness and partial color blindness (protanopia, deuteranopia, blue-yellow blindness, etc.).

[0056] In general, color-blind patients ca...

Abstract

The invention discloses an image brightness conversion method based on a Craik-O 'Brien effect. The method comprises the steps of obtaining image information; and respectively calculating the to-be-displayed brightness of each pixel point in the image, wherein the to-be-displayed brightness is used for enabling the brightness change trend of the image to be unchanged and the brightness change amount to be increased when each pixel point is displayed according to the respective to-be-displayed brightness; and re-coloring the image based on the to-be-displayed brightness to obtain an image afterbrightness conversion. Therefore, the brightness difference in the image is increased, and based on the Craik-O 'Brien effect, because the brightness of places with different colors in a common imageis different, the brightness difference is enhanced by changing the brightness, so that the identification of human eyes on the image contour can be improved, and people can read information carriedin the image more easily. In the scheme provided by the invention, the brightness change is more obvious by changing the brightness in the picture, so that a color blindness patient with color readinginconvenience can read the information in the picture according to the brightness.

Description

technical field [0001] The present application relates to the technical field related to picture display, and in particular to a method, device and equipment for image brightness transformation based on the Craik-O'Brien effect. Background technique [0002] Congenital color vision disorder, commonly known as color blindness, is the inability to distinguish various colors or certain colors in the natural spectrum. Color blindness is more common due to congenital factors. There are far more male patients than female patients. Color blindness is divided into full color blindness and partial color blindness (protanopia, deuteranopia, blue-yellow blindness, etc.). [0003] In general, color-blind patients cannot effectively recognize some color changes in the image, and it is difficult to read some pictures that carry information with color changes. Contents of the invention [0004] The purpose of this application is to provide a method, device and equipment for image brig...
