Embodiment Construction

[0065] Viewing images on electronic devices at night can disrupt our biological clock and may cause sleep disturbances. Therefore, it is desirable to minimize the above negative effects on the biological clock.

[0066] Hereinafter, embodiments of the described technology will be explained in detail with reference to the accompanying drawings. In this disclosure, in some cases and according to those skilled in the art, the term "substantially" includes the meaning of completely, nearly completely or to any obvious degree. In addition, "formed on" can also mean "formed on". The term "connected" may include electrical connections.

[0067] figure 1 is a flowchart illustrating a method of compensating an image based on light adaptation according to an example embodiment. figure 2 is shown by figure 1 A method to compensate the view of the process of image data. image 3 is to show reference figure 1 A plot of the method's visibility curve as a function of the lighting env...

Abstract

A method of compensating an image based on light adaptation, a display device using the method, and an electronic device are disclosed. In one aspect, the method includes the steps of: determining a degree of light adaptation based on the amount of long-wavelength light in the lighting environment at which the image is displayed; The image data used to realize the image is converted via the CIE-XYZ color space into image data expressed in the CIE Long-Medium-Short (LMS) color space; the degree of light adaptation is applied to the converted image data expressed in the CIE-LMS color space, to generate compensated image data; and converting the compensated image data expressed in the CIE-LMS color space into image data to be displayed in the CIE-RGB color space via the CIE-XYZ color space.

Description

technical field [0001] The described technology generally relates to a method of compensating an image based on light adaptation, a display device utilizing the method, and an electronic device. Background technique [0002] Recently, due to the increase in the use of electronic devices (eg, televisions, smartphones, tablet computers, etc.), a large number of related electronic devices (ie, display devices included in electronic devices) are being used continuously for a certain period of time. A study of the effects of devices on users. Normally, serotonin is produced (or secreted) in the human body during the day, and melatonin is produced (or secreted) in the body at night. Namely, the production of melatonin triggers sleep. [0003] Short-wavelength light (eg, blue light with a center wavelength of 464 nm) inhibits melatonin production in the body. Therefore, when a user uses an electronic device for a long time at night, the production of melatonin in the body may be...
