Abstract

A method for adjusting characters of a page includes determines a selected page on a display device of an electronic device. Sizes of characters on the selected page are acquired. An adjustment ratio of the characters on the selected page is computed according to a predetermined calculation method. A size of each of the characters on the selected page is adjusted according to the acquired sizes of the characters on the selected page and the computed adjustment ratio of the characters on the selected page. Each of the characters on the selected page on the displaying device is displayed with the adjusted size of each of the characters on the selected page.

First claim

What is claimed is:

1. A computer-implemented method for adjusting characters of a page using an electronic device being executed by a processor of the electronic device, the method comprising:
determining a selected page on a display device of the electronic device;
acquiring sizes of characters on the selected page;
computing an adjustment ratio of the characters on the selected page according to a predetermined calculation method;
adjusting a size of each of the characters on the selected page according to the acquired sizes of the characters on the selected page and the computed adjustment ratio of the characters on the selected page; and
displaying each of the characters on the selected page on the displaying device with the adjusted size of each of the characters on the selected page;
wherein the adjustment ratio of the characters on the selected page is computed according to the predetermined calculation method by:
acquiring sizes of characters in a first preset region of the selected page;
acquiring sizes of characters in a second preset region of the selected page;
computing a weighted average size according to the sizes of the characters in the first preset region and the sizes of the characters in the second preset region; and
computing the adjustment ratio of the characters on the selected page by dividing a preset size by the weighted average size;
wherein the weighted average size is computed according to a formula of
Fw avg=Σ i=1 n ( f ( i )/ n×w 1)+Σ i=1 m ( g ( i )/ m×w 2))/( w 1+ w 2),

f(i) representing a size of a ith character in the first preset region, w1 representing a weight corresponding to the characters in the first preset region, n representing a number of the characters in the first preset region, g(i) representing a size of a ith character in the second preset region, w2 representing a weight corresponding to the characters in the second preset region, m representing a number of the characters in the second preset region.

2. An electronic device, comprising:
a processor; and
a storage device that stores one or more programs, when executed by the at least one processor, cause the at least one processor to:
determine a selected page on a display device of the electronic device;
acquire sizes of characters on the selected page;
compute an adjustment ratio of the characters on the selected page according to a predetermined calculation method;
adjust a size of each of the characters on the selected page according to the acquired sizes of the characters on the selected page and the computed adjustment ratio of the characters on the selected page; and
display each of the characters on the selected page on the displaying device with the adjusted size of each of the characters on the selected page;
wherein the adjustment ratio of the characters on the selected page is computed according to the predetermined calculation method by:
acquiring sizes of characters in a first preset region of the selected page;
acquiring sizes of characters in a second preset region of the selected page;
computing a weighted average size according to the sizes of the characters in the first preset region and the sizes of the characters in the second preset region; and
computing the adjustment ratio of the characters on the selected page by dividing a preset size by the weighted average size;
wherein the weighted average size is computed according to a formula of
Fw avg=Σ i=1 n ( f ( i )/ n×w 1)+Σ i=1 m ( g ( i )/ m×w 2))/( w 1+ w 2),

f(i) representing a size of a ith character in the first preset region, w1 representing a weight corresponding to the characters in the first preset region, n representing a number of the characters in the first preset region, g(i) representing a size of a ith character in the second preset region, w2 representing a weight corresponding to the characters in the second preset region, m representing a number of the characters in the second preset region.

3. A non-transitory storage medium having stored thereon instructions that, when executed by a processor of an electronic device, causes the processor to perform a control method, wherein the method comprises:
determining a selected page on a display device of the electronic device;
acquiring sizes of characters on the selected page;
computing an adjustment ratio of the characters on the selected page according to a predetermined calculation method;
adjusting a size of each of the characters on the selected page according to the acquired sizes of the characters on the selected page and the computed adjustment ratio of the characters on the selected page; and
displaying each of the characters on the selected page on the displaying device with the adjusted size of each of the characters on the selected page;
wherein the adjustment ratio of the characters on the selected page is computed according to the predetermined calculation method by:
acquiring sizes of characters in a first preset region of the selected page;
acquiring sizes of characters in a second preset region of the selected page;
computing a weighted average size according to the sizes of the characters in the first preset region and the sizes of the characters in the second preset region; and
computing the adjustment ratio of the characters on the selected page by dividing a preset size by the weighted average size;
wherein the weighted average size is computed according to a formula of
Fw avg=Σ 1=1 n ( f ( i )/ n×w 1)+Σ i=1 m ( g ( i )/ m×w 2))/( w 1+ w 2),

f(i) representing a size of a ith character in the first preset region, w1 representing a weight corresponding to the characters in the first preset region, n representing a number of the characters in the first preset region, g(i) representing a size of a ith character in the second preset region, w2 representing a weight corresponding to the characters in the second preset region, m representing a number of the characters in the second preset region.
