Description
k ? -24,3 - -) 5 1 FUNCTION SELECTION CIRCUIT FOR ELECTRONIC APPARATUS AND
CONTROL METHOD USING THE CIRCUIT The present invention relates to electronic equipment, and more particularly to a function selection circuit for an electronic apparatus, which circuit can select the various functions stored in a system by means of one or two keys. The invention also relates to a method for controlling such equipment by use of the function selection circuit.
As more diverse functions have been built into electronic equipment, so operating key panels have become more complicated. For example, a video tape recorder (VTR) performs various functions such as PLAY, PAUSE, MEMORY, EDIT, STOP, SS (SPEED SEARCH), FF (FAST FORWARD), REW (REWIND), TIME, PGM (PROGRAM), and REC (RECORD). Therefore, the key panel must include a key for each of these functions.
The increased complexity of such key panels has increased the probability of erroneous operation by the user pressing an incorrect key when selecting a given function. Also, many ports must be allocated for electronically scanning the key panel.
An object of the present invention is to provide a function selection circuit for an electronic apparatus and to a control method utilising same, in which each function is sequentially displayed or indicated by means of a mode key and a chosen function is selected by a mode selection key when the desired function is displayed or highlighted.
The scope of the present invention is defined by each and every one of the appended claims, alone or in combination.
In particular, a first aspect of the present invention provides a function selection circuit for an electronic apparatus, the circuit comprising:- 2 a mode search key for sequentially searching and causing members of a predetermined range of functions to be indicated; an on-screen display part for displaying the range of functions and their sequential indication for selection; a mode selection key for selecting a desired function indicated as a result of operating the mode search key; and a microcomputer connected to the on-screen display part, the mode search key and mode selection key for controlling said apparatus according to the function selected.
A second aspect of the present invention provides a method of electronic function selection for controlling the operation of an electronic apparatus, the method comprising:- a set-up routine for determining whether an input key has been pressed; a search process for sequentially searching and indicating members of a predetermined range of functions in response to sequential pressing of a mode search input key; displaying at least the currently indicated function; and an execution process for executing a function indicated during the search process in response to pressing of a mode selection input key.
These and other advantages of the present invention will become more apparent from the following description of a preferred embodiment and with reference to the accompanying drawings in which:
Fig. 1 is a block diagram of a function selection circuit according to the present invention, for use in electronic equipment; k 3 Fig. 2 is a flow chart for explaining a control method using the circuit shown in Fig. 1; and Fig. 3 is a block diagram of a remote control embodiment of a function selection circuit according to the present invention.
Fig. 1 shows a block diagram of a function selection circuit comprising a microcomputer (MICOM) 12 for controlling a system in accordance with selected functions. The microcomputer is connected to the outputs of both a mode search key 10 and a mode selection key 11. The mode search key sequentially selects functions indicated by a moving cursor and the mode selection key allows the user to select a given function when highlighted by the cursor. An on-screen display part 13 for displaying the functions is connected to an output of the MICOM. As used herein, the terms onscreen display and on-screen display part refer to cathode-ray tube displays, liquid crystal displays or any other means capable of electronically displaying visual information or an image, and/or to electronic circuitry for operating any such display. A drive mechanism 14 and circuit 15 are provided for controlling the operation of the system are also connected to output of the MICOM.
If the mode search and the mode selection operations are to be remotely controlled, the mode search key 10 and the mode selection key, the MICOM 12, and the on-screen display part 13 will be located in a remote transmitter 100, whilst the drive mechanism 14 and the circuit part 15 will be located in a receiver 200 (see Fig. 3).
Fig. 2 shows a flow chart explaining the way in which the function selection circuit controls an electronic system.
1 4 The method comprises a set-up routine Ll for determining whether an input key has been pressed, or the identity of a pressed key, a search process P1 for moving a cursor to select one of the displayed functions whenever the mode search key 10 is pressed in the set-up routine L1, and an execution process P2 for executing the function selected during the mode search process P1, when the mode selection key input 11 is pressed. If the mode selection key is not pressed, the cursor is moved to the next function.
The mode search process P1 comprises a step S4 for distinguishing whether or not the mode search key 10 is pressed and a step S5 for moving the cursor every time the mode search key pressed.
Instead of a cursor, any other means of sequentially highlighting individual members of the displayed range may be used, eq. sequential change in brightness or colour etc. Alternatively, the mode search key may cause each of the members of the range of functions to be displayed alone, in sequence.
The execution process P2 comprises a step S6 for distinguishing whether or not the mode selection key 11 is pressed or not and a step for executing the selected mode function when step S6 establishes that the mode conversion key has indeed been pressed. A step S8 is also provided for moving the cursor to the next mode if step S6 establishes that the mode selection key 11 has not been pressed. In other words, if the mode selection key 11 is not pressed during the period of step S6, the cursor is moved automatically to the next mode by the step S8 and the mode search process P1 is repeated.
In the embodiment of the present invention as described above, first, the MICOM 12 scans the ports corresponding P1 and P2 to check the generation of the key signals. If the mode search key signal is detected through the port P1, the MICOM 12 moves the cursor to a first function displayed on screen, and if the mode search key 10 is pressed once more, the cursor is moved to the second function displayed on screen and so on. During the mode search, when a desired function is indicated, one presses the mode selection key 11.
Then, MICOM 12 controls the drive mechanism 14 and the circuit 15 according to the selected function at which the cursor stopped after recognition of the appropriate mode selection signal at the port P2.
In the remote control embodiment (Fig. 3), if the mode search key 10 in the remote transmitter 100 is pressed, the MICOM 12 in the remote transmitter outputs a control signal to move the cursor to the first function displayed by the on-screen display part 13.
When the cursor has been moved to a user's desired mode by repeating the above operation, that mode is selected by the mode selection key 11 and the appropriate mode selection signal is provided to the MICOM 12, so that a control signal for controlling the drive mechanism 14 and the circuit 15 is sent to the receiver 200. Thus, the selected mode function is effectively executed by the remote control signal provided from the MICOM 12.
Referring again to Fig. 2, the MICOM 12 checks the generation of the key signal by sequentially providing the scan signals to the ports P1 and P2 during the steps S2 and S3 of the set-up routine L1. If the key signal is recognized during step S3, then subsequently during step S4, it is distinguished as to whether it is the mode search signal or the mode selection signal.
If the input key is found to be the mode search key, then the cursor is moved to the first function of the on-screen display 13 during step S5. IF the input key is found to be the mode selection key, during step S6 the MICOM 12 controls the drive mechanism 14 and circuit k_ 6 to execute the selected function at which the cursor stopped during step S7. However, if after a predetermined time delay, the mode selection key 11 is not pressed during step S8, then the cursor is automatically moved on to the next mode.
It is assumed that the functions listed in table 1 have already been set up in the MICOM 12.
Table 1 press tizes press tizes MODES of MODE SELECTION of MODE SEARCH key key 0 0 =P 0 1 PLAY 0 2 REV 0 3 FF 0 4 SPEED SEARCH 0 5 REC 0 6 PAUSE 0 7 MEMORY 0 8 EDIT 0 9 PROGRAM FF FF The cursor is moved sequentially to the corresponding pre-set function, every time the mode search key is pressed. Then, if the mode selection key 11 is pressed when the cursor is placed at (say) the FF (Fast Forward) function, the MICOM 12 recognizes that the FF function is selected and controls the drive mechanism 14 to run the tape fast after unloading.
As mentioned hereinbefore, according to the present invention, the mode search and selection functions can be remotely controlled by installing the on-screen display 13 (where the stored functions are displayed), 7 the mode search key, and the mode selection key in the remote transmitter and by installing the MICOM, the drive mechanism, and the circuit part in the receiver (the MICOM may alternatively be located in the transmitter).
Alternatively, the mode search and mode selection functions can he confirmed on a television screen by connecting the on-screen display part to a television.
Therefore, the present invention reduces the number of keys which are oneto-one matched to each function in a conventional arrangement, down to two or three keys. This in turn reduces the numbers of ports and the area of PCB (printed circuit board) in the circuitry. Furthermore, the present invention reduces manufacturing costs and reduces the probability of inadvertent errors when selecting the key.
The invention is in no way limited to the specific embodiments hereinbefore described. Various modifications of the disclosed embodiments as well as other embodiments of the invention, all within the scope of the invention as defined by the appended claims, will now become apparent to persons skilled in the art upon reference to this description of the invention.
