Abstract: The invention relates to an electronic device, which includes camera means, including at least one camera element (CAM1) for forming image data (DATA1) from an imaging subject, a first lens arrangement (F1) according to a set focal length, arranged in connection with the camera means, and means for processing the image data (DATA1) into image information (IMAGE), the processing including, for example, zooming of the imaging subject. The said camera means 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 (F1) in an established manner and from the sets of image data (DATA1, DATA2) formed by the first and second camera elements (CAM1, CAM2) is arranged to be processed by using the data-processing means the image information (IMAGE) with the desired zooming of the imaging subject. In addition, the invention also relates to a method and program product.

Abstract: The invention relates to arranging data flow control in a data transfer system comprising a sender and at least two protocol entities serving the transmission of data from the sender. The originating protocol entity of a suspension request primitive is checked. Suspension is set as the data transmission status for the protocol entity that has originated a suspension request primitive. The originating protocol entity of a resume request primitive is checked before sending it to the sender. Also the status information is checked. Transmission of the resume request primitive to the sender is prevented if suspension is set for any other protocol entity than the originating protocol entity of the resume request primitive.
