Embodiment Construction

[0013] Throughout the following description, the same reference numerals are used to identify similar parts.

[0014] refer to figure 1 A portable computing device such as a personal digital assistant (PDA) device with wireless data communication capabilities such as the so-called smart phone 100 constitutes a combination computer and communication handset. Accordingly, the smartphone 100 includes processing resources such as, for example, a processor 102 coupled to one or more input devices 104, such as a keypad and / or touch screen input device. The processor 102 is also coupled with volatile storage devices, such as random access memory (RAM) 106 , and nonvolatile storage devices, such as read only memory (ROM) 108 .

[0015] A data bus 110 is also provided and coupled to the processor 102, which is also connected to a video controller 112, an image processor 114, an audio processor 116, and an optional memory storage unit such as a flash memory unit 118. Plug-in storage m...

Abstract

A method of transferring image data to a composite memory space (236) comprises including masking data defining a reserved output area (230) in a first memory space (212) and containing first time-varying data having a first frame rate associated therewith. Second time-varying image data (220) is stored in a second memory space (222) and is associated with a second frame rate. At least part of the first image data is transferred to the composite memory space and at least part of the second image data (220) is transferred to the composite memory (236). The mask data is used to provide the at least part of the second image data (220) such that, when output, the at least part of the second image data (220) occupies the reserved output area (230).

Description

technical field [0001] The invention relates to a method for transmitting image data, which is displayed, for example by a display device, and corresponds to a type of time-varying image with different frame rates. The invention also relates to an image processing device, wherein said image processing device is, for example, of the type for transferring image data displayed by a display device and corresponding to time-varying images of different frame rates. Background technique [0002] In the field of computing devices such as portable electronic devices, it is known to provide a graphical user interface (GUI) so that a user can be provided with the output of the portable electronic device. GUI can be e.g. run on Linux TM An application such as an application called "QT" on the operating system, or the GUI can be, for example, Windows produced by Microsoft Corporation. TM A component of an operating system such as an operating system. [0003] In some cases, the GUI mu...
