Abstract
A method for operating electronic glasses including a display and a processor is provided. The method includes the steps of taking an image to be displayed as input data, distorting the original image through image manipulation executed by the processor in relation to the vision impairment based on predefined distortion criteria creating pre-compensated image data, first increasing the relative brightness of the pre-compensated image data generating increased brightness image data, second increasing the contrast of the increased brightness image data generating increased contrast image data, and displaying the generated image data on the display.
Claims5
A method for operating electronic glasses comprising a display and a processor, the method comprising:
- taking an original image to be displayed as input data;
- distorting said original image through image manipulation of the input data executed by the processor in relation to a vision impairment based on predefined distortion criteria comprising calculation of an inverted point spread function on the basis of said predefined distortion criteria based on said vision impairment and a de-convoluting step of the result of the inverted point spread function with the original image data creating pre-compensated image data;
- a brightness increasing step, wherein the brightness of the pre-compensated image data is increased generating increased brightness image data;
- a dynamic contrast range increasing step, wherein the dynamic contrast range of the increased brightness image data is increased generating increased dynamic contrast range image data as output image data to be displayed;
- and
- displaying the generated output image data on the display.
Electronic glasses for a visually impaired user, comprising a computer program product provided to be executed on a processor of a visual communication apparatus having a display, wherein the computer program product comprises an inverted point spread function module to calculate an inverted point spread function based on predetermined parameters of vision impairment, a first filter configured to increase a brightness of image data, a second filter to increase the dynamic contrast range of image data and a de-convolution filter, wherein the computer program product is configured to apply the deconvolution filter on original image data with the result of the inverted point spread function, wherein the first brightness increase filter is applied after the application of the deconvolution filter, and wherein the second contrast increase filter is directly applied after the first brightness increase filter.
