Problems solved by technology

[0005] It should be noted that for the multi-touch operations described above, although various touch operations are possible, multi-touch operations become complicated compared to single-touch operations because multiple fingers are used

Embodiment 2

[0181] Furthermore, in the first and second embodiments described above, when a touch operation of moving a finger to draw a circle is performed, the touch operation is determined as a zoom operation and the zoom operation is performed.

[0182] However, the present invention is not limited to this example, and as Figure 14 As shown, when a touch operation in which a finger is lightly brushed (flicked) over the monitor image Mp is performed, the CPU 110 determines the flick operation based on the finger trace, and the CPU 110 can recognize that the zoom-in operation has been performed and perform the zoom-in operation.

[0183] More specifically, the CPU 110 recognizes the trace of the flick, sets the screen coordinate X of the start point of the flick as the center point of the zoom, and also sets the zoom scale according to the speed of the flick (speed of finger movement).

[0184] At this time, for example, the zoom scale is set such that the faster the flick speed is, th...

Embodiment 3

[0189] Furthermore, in the first embodiment described above, the CPU 110 performs the zooming operation at predetermined time intervals and at a zooming scale corresponding to the length of the drawn arc.

[0190] The present invention is not limited to this example, and the CPU 110 may perform a zoom operation using a quarter of the zoom ratio of a full circle whenever the length of the drawn arc reaches, for example, a quarter of the circle.

[0191] In addition, for example, whenever the length of the drawn arc reaches the length of the circumference, that is, whenever a circle is drawn, the zooming operation may be performed at a zoom ratio of a full circle.

[0192] By doing so, it is possible to control such that the zoom operation is not performed until the drawn arc reaches a predetermined length, and it is possible to prevent erroneous operations (such as performing a zoom operation when the touch panel 109 is touched by mistake).

[0193] The present invention is not...

Abstract

A digital image processing device is provided that improves operability when performing a scaling up / scaling down operation. Based on a single trajectory when a touch position on a display screen of a display portion moves, a center point and ratio used to scale up or scale down the image are set. In this way, for example, it is possible to scale up and scale down the image by an easy touch operation of simply tracing the trajectory with a single finger (namely, by a single-touch operation).

Description

technical field [0001] The present invention provides an information processing device employing an image zoom feature that zooms a displayed image using a touch operation. Background technique [0002] In known techniques, an information processing device may employ a touch panel. With this type of information processing apparatus, more intuitive operations can be realized on the touch panel by employing touch operations such as tapping, dragging, flicking, and the like. For example, flicking is an operation in which a finger (or a touch pen, etc.) is lightly drawn across the surface of the touch panel. [0003] In addition, in recent years, information processing apparatuses having a so-called multi-touch panel on which pinch out and pinch out ( pinch in) and other operations. In this regard, the pinching operation is an operation in which two fingers touch the touch panel and the space between the two fingers becomes wider. The matching operation is an operation in wh...
