Abstract

A print format adjustment system includes a receiving module, a visual condition determination module, a print format determination module, and a print control module. The receiving module receives content for printing in a first print format. The visual condition determination module establishes the sharpness of vision of a viewer in front of a display, at a predetermined view distance. The print format determination module determines a second print format based on both the first print format and the visual condition of the viewer. The print control module prints the content in the second print format.

Claims

1. A computer-implemented method for adjusting print format in an electronic device, the method comprising:

receiving content for printing in a first print format by a processor of the electronic device;

continuously measuring current distance between a viewer and a display of the electronic device by a distance detecting device of the electronic device;

when the current distance between the viewer and the display is equal to a predetermined distance, determining a visual condition of the viewer at the predetermined distance by the processor;

determining a second print format based on the first print format and the visual condition of the viewer by the processor; and

printing the content in the second print format;

wherein the step of determining the visual condition of the viewer comprises;

displaying a visual acuity test chart on the display;

determining a visual acuity index by testing the viewer using the visual acuity test chart; and

determining a minimal size relative to the visual acuity index, wherein the minimal size is a size of which a visual element smaller than is unrecognizable for the viewer at the predetermined distance;

the step of determining the second print format comprises obtaining size of the second print format by using an equation as follows;

2. An electronic device, comprising:

a storage unit;

a processor coupled to the storage unit;

one or more programs being stored in the storage unit and executable by the processor, the one or more programs comprising;

a receiving module configured for receiving content for printing in a first print format;

a distance measurement module configured for continuously measuring current distance between a viewer and a display of the electronic device;

a visual condition determination module configured for determining a visual condition of the viewer at a predetermined distance when the current distance between the viewer and the display is equal to the predetermined distance;

a print format determination module configured for determining a second print format based on the first print format and the visual condition of the viewer; and

a print control module configured for printing the content in the second print format;

wherein the visual condition determination module is configured for displaying a visual acuity test chart on the display, determining a visual acuity index by testing the viewer using the visual acuity test chart, and determining a minimal size relative to the visual acuity index, where the minimal size is a size of which a visual element smaller than is unrecognizable for the viewer at the predetermined distance; and

the second print format determination module is configured for obtaining size of the second print format by using an equation as follows;
