Description

METHOD IN A MOBILE STATION EQUIPPED WITH A ROTATABLE ELEMENT AND A MOBILE STATION
The present invention relates to a method in a mobile station equipped with a keypad component, a camera, and at least one rotatable element relative to the keypad component, the element having at least one imaging mode corresponding to an imaging position relative to the keypad component, and one off position, which imaging position is detected with the aid of at least one sensor, and in which imaging takes place in the imaging' mode by running a camera application loaded in the operating memory, using the operating system of the mobile station. The invention also relates to the mobile station itself.
In a mobile station there is an operating system, which permits applications to be run in it. In several mobile stations there is a camera, in which case several applications independent of telephone operation relate to the camera and to image processing. In the camera application, the display becomes the viewfinder of the camera while the keypad is used to control the functions of the camera .
A traditional mobile-station operating system is of the so- called monotasking type, in which only one application can be running at a time. Nowadays, multitasking operating systems, which permit two or more applications to be run simultaneously, are quite widely used.
Most mobile stations equipped with a camera comprise a special camera component, which can be rotated to and from the imaging position. On the other hand, camera solutions are also known, in which the lens of the camera is protected by a movable flap. This has an obvious imaging position for imaging and a shield position to protect the lens. In existing mobile stations equipped with a rotating/moving camera component, the use of the camera requires the user to perform several operations . Besides rotating or moving the camera component, one or more keypad operations are generally required to start imaging. Correspondingly, in a mobile station equipped with a rotating display component, the viewing of the images requires the display component to be rotated to the display position and, in addition, keypad operations.
US application publication US 2004/0192220 Al discloses a mobile station with a clamshell basic construction, in which the mobile station changes to the camera mode by rotating the display component through 180°. The camera is on the opposite side of the display component. In addition, the display compo- nent/camera can be rotated through 90° . In known camera phones, the camera application is loaded into the memory and run by the operating system by pressing a key. Thus quite obviously in this case too a reed-relay causes the camera application to boot and start.
The invention is intended to create an imaging function in a mobile station according to the preamble to Claim 1, which will be easier to use and faster than previously. The characteristic features of the method according to the present in- vention, are stated in the characterizing portion of the same Claim 1. The characteristic features of the mobile station according to the invention are correspondingly stated in Claim 6. The rotating/moving element can be used to quickly start any application whatever in a multitasking environment .
When a multitasking operating system is used and the application is preloaded in the operating memory, it will start immediately. The difference is often considerable compared to starting, in which the application is, for example, on a mem- ory card and is loaded into the memory from it. Traditionally, the camera application does not open and close, instead the operating system moves, for example, the focus to and from this application, either to the previous application or to the main menu. In this case, the term moving the focus refers to the running of the program, when it gains control of the display and keypad and generally the use of the resources provided by the operating system. The camera application is held continuously in the operating memory and is thus ready to be taken immediately into focus. In any case, the camera applica- tion operates in the background, even through it is not used.
In one embodiment, imaging or some other similar function is closed when leaving the image position (or similar) . In one third embodiment, the sensor detecting the imaging position of the camera component is a so-called Hall sensor. Other benefits and embodiments of the invention will be examined hereinafter, in connection with the examples.
In the following, the invention is described in detail with reference to the accompanying drawings depicting some embodiments of the invention, in which
Figure 1 shows one mobile station according to the invention in closed mode, Figure 2 shows the mobile station of Figure 1 with the camera component in the imaging position, Figure 3 shows the mobile station of Figure 1 in the telephone mode,
Figure & shows the mobile station of Figure 1 in the imaging and viewing mode,
Figure 5 shows a block diagram of the mobile station, and Figure 6 shows a flow chart of the initiation of the camera or other similar application. The mobile station 10 of Figure 1 comprises first of all a body component 12 and a camera component 14, in which there is a camera 15. The body 12 is in two parts, comprising a keypad component 19 and a display component 18. The first display 20 can be read in closed mode (Figure 1) . In Figure 2, the camera component 14 of the mobile station 10 is turned to the imaging position, after which the camera application (camera mode) is started in the manner to be described hereinafter. A sensor 16, which is a Hall sensor, detecting the imaging position, is marked in Figure 2.
In Figure 3, the mobile station is in the telephone mode, when the display component is rotated through nearly 180°, so that the large display 20' is revealed in the display component and the keypad 22 in the keypad component 19. This includes a navigation key 22 ' . The clamshell construction of this mobile station 10 is special, as both halves are attached to the camera component by pivot joints 24 and 25. In addition, there is a pivot joint 26 in the display component, for rotating it to the imaging position (Figure. 4) , in which it is possible to take still images or a video clip. A second sensor 16' is marked in Figure 3 for detecting the position corresponding to the telephone mode while correspondingly the base of the display component 18 includes a third sensor 16".
Because the applications are ready in the operating memory, it is sufficient for the operating system to give the focus to them, when the corresponding sensor detects a change in position. Thus, when changing from the mode of Figure 1 to the mo- de of Figure 2 , the rotation of the camera component 14 to the imaging position causes, with the aid of the sensor 16, an interrupt operation in the operating system, on the basis of which the camera application starts (the focus changes to the program). Correspondingly, the sensors 16' and 16" each cause the start of a preselected application. Correspondingly, the focus can be moved away from the camera application, for example, to the main menu, with the aid of an interrupt message when the camera application will move to the background.
In one embodiment, the camera application starts when the camera module is turned slightly (e.g., 5°- 15°), in such a way that the sensor 16 detects the rotation (Figure 2) . In this case, the HW interrupt creates a SW-based key event, by means of which the camera application is changed to the cover dis- play in the multitasking operating system and vice versa on exit from the mode in question. Once the mode has been activated, the rotation of the camera module 14 alters the direction of the viewfinder image, in such a way that it is always in the correct direction.
The imaging and viewing mode ( λ Image-mode ', Figure 4) activates when the display component 18 is first of all turned through about 90° and rotated slightly, when the third sensor 16" detects the rotation.
Figure 5 shows a simplified block diagram of the mobile station. The microprocessor 34 (CPU) is the central component, which processes data according to the command codes contained in the program. In the mobile station there is generally a mass memory, for example 38. Primarily, the operation requires a program memory 36' (ROM) and an operating memory 36 (RAM) . Applications are preloaded from the mass memory 38 or the program memory 36' (ROM) to the RAM memory 36 as soon as the mobile station is switched on.
The camera 15 is connected to a video processor 32, which is connected to the microprocessor 34. The keypad 22 and the position sensors 16, 16', 16" are connected to the input unit 30, which transmits data to the microprocessor 34. The data output is processed by an output unit 40, from which the data is led to the displays 20 and 20' and to the audio unit 42.
The programmatic control of the preloaded applications is shown in the flow chart of Figure 6.
Switching on 50 the mobile station immediately leads to the loading 51 of the preselected applications into the operating memory. It is not even necessary to enter the PIN code (e.g., GSM telephone) . After that, there is an interrupt detection loop, stage 52, in the program of the operating system. The position sensors (16, 16', 16") create so-called interrupts, each one of which has its own number. When an interrupt oc- curs, the interrupt number is retrieved, stage 53, with the aid of which an application can be selected, stage 54. The selection 55 guides the operation to an application according to the interrupt number (one of stages 56, 57, or 58) . This is a question of moving the focus to the program in question, or in connection with termination, of moving the focus from a certain application to the main menu or some other preselected application, in which case the camera application moves to the background.
