Abstract
A camera installed in a wireless terminal comprises a first electronic zooming means to operate by hardware and a second electronic zooming means to operate by software. The first electronic zooming means quickly select one of several pictures with predetermined scale factor. The second electronic zooming means zoom in or out a picture in small steps. An operator can quickly display a picture of desired scale factor by these two means. Further, in a foldable type terminal with a magnetic sensor, a picture with desired scale factor can be displayed by adjusting an angle between a first housing and a second housing.
Claims11
A wireless terminal comprising a camera, comprising:
- a first electronic zooming means for zooming in or out a picture of an object by hardware;
- a second electronic zooming means for zooming in or out a picture of an object by software;
- a control unit for controlling the first and the second electronic zooming means;
- a display;
- and
- an operation key,
- wherein the first electronic zooming means is operated by a user clicking the operation key one or more times to display a picture of a scale factor which is near to a desired zoomed picture, and
- wherein the second electronic zooming means is operated by a user continuously pushing the operation key to finely tune a zooming scale factor to smoothly and quickly display a picture with a desired scale factor.
A method for operating a wireless terminal comprising a camera comprising the steps of:
- zooming in or out a picture by a first electronic zooming means based on hardware;
- zooming in or out a picture by a second electronic zooming means based on software,
- wherein the first electronic zooming means is operated by a user clicking an operation key one or more times to display a picture of a scale factor which is near to a desired zoomed picture, and
- wherein the second electronic zooming means is operated by a user continuously pushing the operation key to finely tune a zooming scale factor to smoothly and quickly display a picture with a desired scale factor.
A wireless terminal comprising a camera, comprising:
- a first electronic zooming unit configure to zoom in or out a picture of an object by hardware;
- a second electronic zooming unit configured to zoom in or out a picture of an object by software;
- a control unit for controlling the first and the second electronic zooming units;
- a display;
- and
- an operation key,
- wherein the first electronic zooming unit is operated by a user clicking the operation key one or more times to zoom the picture of the object in large increments for each click of the operation key, and
- wherein the second electronic zooming unit is operated by a user continuously holding the operation key in a pushed position to zoom the picture of the object in small increments.
