Abstract

In order to enable easier magnification and reduction of a displayed image, an electronic device 1 includes a display unit 30, a pressure detection unit 60 and a control unit 10, such that the display unit 30 displays an image, the pressure detection unit 60 detects a pressure, and the control unit 10, based on the pressure detected by the pressure detection unit 60, controls magnification or reduction of the image.

Claims

1. An electronic device comprising:

a display configured to display an image;

a pressure detection unit configured to detect a pressure;

a contact detection unit comprising a touch face, the contact detection unit being configured to detect a contact of an object at any position on the touch face; and

a controller configured to perform magnification or reduction of the image around the contact and control a ratio thereof step by step, based on the pressure detected by the pressure detection unit,

wherein the control of the ratio thereof step by step comprises detecting a sweep amount or a sweep direction, calculating a first ratio used for a first magnification or reduction and calculating a second ratio used for a second magnification or reduction by adjusting the first ratio, and one of the first ratio and the second ratio is calculated based on the pressure, and-the other of the first ratio and the second ratio is calculated based on the sweep amount or the sweep direction,

wherein the object is a single object, and

wherein the magnification or reduction is performed with the single object.

2. A display method comprising steps of:

displaying an image;

detecting a pressure;

detecting a contact of an object at any position on a touch face; and

performing magnification or reduction of the image around the contact and controlling a ratio thereof step by step, based on the detected pressure of the contact,

wherein the controlling of the ratio thereof step by step comprises detecting a sweep amount or a sweep direction, calculating a first ratio used for a first magnification or reduction and calculating a second ratio used for a second magnification or reduction by adjusting the first ratio, and one of the first ratio and the second ratio is calculated based on the pressure, and-the other of the first ratio and the second ratio is calculated based on the sweep amount or the sweep direction,

wherein the object is a single object, and

wherein the magnification or reduction is performed with the single object.
