Embodiment Construction

[0023] Today, many electronic devices 10 include a camera 12 . Such devices include, in addition to digital cameras, mobile workstations, PDA (Personal Digital Assistant) devices and similar "smart communicators". In this relation, the concept of "electronic device" can be broadly understood. For example, it can be a device that is or can be equipped with digital imaging capabilities. Hereinafter, the present invention is described by taking the mobile station 10 as an example.

[0024] Fig. 1 shows a rough schematic example of functional units in a device 10 basically according to the invention. Device 10 may include functional components as shown in FIG. 1 . The device 10 consists of a camera device 12 and a data processing device 11 connected to the camera device 12, which are the basic components for realizing the device 10 according to the present invention, by means of which the program product 30 can be implemented at the HW or SW level, thereby processing Image dat...

Abstract

The invention relates to an electronic device (10), which includes - camera means (12), including at least one camera element (CAMl) for forming image data (DATAl) from an imaging subject (17),- a first lens arrangement (Fl) according to a set focal length, arranged in connection with the camera means (12), and means (11) for processing the image data (DATAl) into image information (IMAGE), the processing including, for example, zooming othe imaging subject (17).The said camera means (12) additionally include at least a second camera element (CAM2) equipped with a second lens arrangement (F2), the focal length of which differs from the focal length of the said first lens arrangement (Fl) in an established manner and from the sets of image data (DATAl, DATA2) formed by the first and second camera elements (CAMl, CAM2) is arranged to be processed by using the data- processing means (11) the image information (IMAGE) with the desired zooming of the imaging subject (17). In addition, the invention also relates to a method and program product.

Description

technical field [0001] The invention relates to an electronic device, comprising: [0002] - an imaging device comprising at least one imaging element for forming image data from an imaging object, [0003] - a first lens assembly according to a set focal length arranged in connection with said camera device, and [0004] - means for processing said image data into image information, said processing comprising eg scaling of an imaging object. [0005] Furthermore, the invention relates to a method and a corresponding program product. Background technique [0006] A separate camera element can be found in a variety of existing electronic devices, one example being a camera phone. The lens group associated with the camera element is arranged substantially fixed, eg without any form of zooming possibility. [0007] Today, digital zoom is used in many known electronic devices. However, it has some known drawbacks. For example, these defects are related to image sharpness. ...
