Example Embodiment

[0027] In order to make the above objectives, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] One of the core concepts of the present invention is: through comparative experiments, it can be known that when human eyes read the text content of "black characters on white background" and "white characters on black background", the light intensity to achieve better reading visual effects is completely different. The human eye is accustomed to reading "black characters on white background" in soft light or darkness, and reading "white characters on black background" under strong light intensity and strong outdoor light. Based on the above principles, with the help of photosensitive devices or manual settings, the palm-sized e-reader can perform "black text on white background" and "white text on black background...

Abstract

The present invention provides a method and device for enhancing the reading effect of e-books, and an electronic terminal. The method includes: a photosensitive component acquires the light intensity value of the current environment; The relationship between the limit value and the critical threshold value; if the light intensity value is greater than the upper limit value or less than the lower limit value, the foreground text chromaticity value is equal to the light intensity value, and the background chromaticity value is equal to 255 minus the light intensity value; if the light intensity If the intensity value is between the upper limit value and the critical threshold value, the foreground text chromaticity value is equal to the upper limit value, and the background chromaticity value is equal to the lower limit value; if the light intensity value is between the lower limit value and the critical threshold value, Then the chromaticity value of the foreground text is equal to the lower limit value, and the background chromaticity value is equal to the upper limit value; the content of the e-book is displayed according to the foreground text and the background chromaticity value. The invention adjusts the foreground text and the background scene according to the intensity of the ambient light, which can maximize the contrast effect, facilitate the reading of the user, and reduce visual fatigue.

Description

technical field [0001] The present invention relates to the technical field of electronic books, in particular to a method and device for enhancing the reading effect of electronic books, and an electronic terminal with the function of reading electronic books. Background technique [0002] With the development of handheld e-readers, e-books have gradually entered people's reading habits. At present, the main purpose of handheld e-book readers is to read various e-books. When the above-mentioned readers display the contents of e-books, they usually display black and white mainly, and generally use foreground text and background blank as the main display form, that is, the traditional The "black text on white background" is the main form or the customized "white text on black background" is provided; the former is a traditional method evolved from paper book printing and reading habits, and the latter is an application method based on personalized reading habits.
