Since the display size of the function menus included in the displayed list displayed on the display unit is adjustable by operating the input devices, a plurality of inputs can be carried out with a small number of input devices. In this way, the number of components can be reduced.
A display apparatus with input devices according to an embodiment of the present invention will be described below with reference to the drawings.
A case in which a display apparatus 1 with input devices according to an embodiment of the present invention is applied to a portable digital cameral will be described. A display unit 2 including a liquid crystal display is disposed, on the side opposite to the digital cameral lens. A frame 3 having a predetermined width surrounds the periphery of the display unit 2.
As shown in the drawings, the left and right areas of the frame 3 are defined as a left section 3a and a right section 3b, respectively, and are disposed opposite to each other, whereas the upper and lower areas of the frame 3 are defined as an upper section 3c and a lower section 3d and are disposed opposite to each other.
In the frame 3, long first input device 4, second input device 5, and third input device 6 are disposed in the left section 3a, the right section 3b, the upper section 3c, respectively, and four fourth input devices 7, which are shorter than the first to third input devices 4, 5, and 6, are disposed in the lower section 3d with equal intervals between each other.
The first to fourth input devices 4, 5, 6, and 7 have smooth operation surfaces 4a, 5a, 6a, and 7a, respectively. The operation surfaces 4a, 5a, 6a, and 7a are exposed from the surface of the frame 3.
When the operator lightly touches any one of the operation surfaces 4a, 5a, 6a, and 7a, the inner switching circuit is switched and predetermined coordinates can be input.
The switching circuit, for example, is constituted of X electrodes and Y electrodes arranged in a matrix (not shown in the drawings). When the operator's finger touching any one of the operation surfaces 4a, 5a, 6a, and 7a, the electric capacitance between the finger and the X and Y electrodes changes. Coordinates that correspond to this change in capacitance are input.
Instead, the operator may slide their finger on and in contact with any one of the operation surfaces 4a, 5a, 6a, and 7a, along the longitudinal direction, so as to change the hierarchy level of a function menu displayed on the display unit 2.
Guide protrusions 3e having a predetermined height are provided around the operation surfaces 4a, 5a, 6a, and 7a, which are exposed from the surface of the frame 3.
In other words, the input devices 4, 5, 6, and 7 are surrounded by the guide protrusions 3e having a predetermined height.
Accordingly, the input operation by the input devices 4, 5, 6, and 7 does not have to be visually confirmed since the input operation can be sensed by touching the guide protrusions 3e.
Next the operation of the display apparatus 1 with the input devices 4 to 7 is described with reference to the drawings. When the display apparatus 1 constituting a digital camera is in a photography mode, the display unit 2 displays a first screen that is capable of displaying an image captured by a charge-coupled device (CCD) (imaging device).
On the first screen in the photography mode, a plurality of icons representing menu items are displayed in the lower area, close the periphery of the display unit 2 in the vicinity of the fourth input devices 7 provided at the lower section 3d of the frame 3.
The plurality of icons are, for example, a first icon 2a, a second icon 2b, and a third icon 2c corresponding to a flash mode, a close-up mode, and a self-timer mode, respectively, which are items of a function menu for the digital camera.
The operation of the third icon 2C corresponding to the self-timer mode will be described as an example. When carrying out self-timer photography, when the photographer's finger touches an operation surface 7a of the rightmost fourth input device 7, as shown in the drawing, corresponding to the third icon 2c, a second screen, such as that shown in
When the first menu list 8 is displayed, the first menu list 8 is set to OFF. At this time, if an operation surface 5a of the second input device 5 corresponding to the first menu list 8 is touched, the switching circuit of the second input device 5 is switched, and a predetermined menu item, e.g., ten-second self-timer, included in the first menu list 8 is selected.
In other words, by operating the input devices 5 and 7, a predetermined function menu item may be started-up or selected.
If the fourth input device 7, which is the leftmost input device among the four fourth input devices shown in the drawings, is touched after selecting the menu item corresponding to the ten-second self-timer, the ten-second self-timer menu item is entered and set and the second screen is changed to the first screen so that the image to be photographed is displayed in a large size.
In other words, by repeatedly operating the same input device 7, a plurality of inputs, such as starting, selecting, and entering a function menu item, is possible. Thus, the display apparatus 1 with input devices 4 to 7 can be easily operated.
If the photographer presses the shutter button after the first screen is displayed again on the display unit 2, the shutter is operated ten seconds later so as to capture the image displayed on the display unit 2.
In case the first to third icons 2a, 2b, and 2c are not used, by operating buttons other than the first to fourth input devices 4 to 7, the display unit 2 displays a third screen including a second menu list 9 corresponding to a plurality of function menu items, as shown in
To select one of the function menu items, such as a self-timer menu item, included in the second menu list 9, the first input device 4 in the vicinity of the menu item, self-timer, is lightly touched by the operator to display the first menu list 8, which is the same menu list shown in
Then, to set the time for the self-timer to, for example, ten seconds, the second input device 5 in the vicinity of the displayed 10-second menu item is lightly touched and then the third input device 6 in the vicinity of a setting mode indication 2d displayed in the upper area of the display unit 2 is lightly touched.
By touching the second left input device 7, as shown in the drawing, in the vicinity of an enter mode indication 2e displayed in the lower area of the display unit 2 after setting the self-timer to ten seconds, the time of the self-timer is set to ten seconds and the second screen is changed back to the first screen so that the image to be photographed is displayed in a large size.
To turn off the self-timer function, the second input device 5 in the vicinity of the OFF menu item displayed in the first menu list 8 is touched.
When the self-timer function is turned off, the shutter is operated immediately after the shutter button is pressed.
Moreover, the operator can scroll the second menu list 9 upward or downward by sliding their finger placed on the operation surface 4a of the first input device 4 upward or downward so that function menu items other than those illustrated in
To view previously captured images, an operation button (not shown in the drawing) other than the first to fourth input devices 4 to 7 are operated so that a plurality of previously captured images are displayed in a displayed list 10, i.e., displayed menu, where the images are arranged along the X and Y directions, as on the display unit 2 in shown in
To print out a predetermined image (menu item) included in the displayed list 10 with a printer, the predetermined image can be selected by touching the first input device 4 and the fourth input device 7 that correspond to the predetermined image and that are disposed along at least two orthogonal sides (left section 3a and upper section 3c) along the X and Y directions of the frame 3.
After selecting the predetermined image, by operating the operation surface 7a of the fourth input device 7 corresponding to the enter mode indication 2e provided the vicinity of the enter mode indication 2e, the selected predetermined image is entered and set so that the image to be photographed is displayed in a large size on the display unit 2.
Then, the selected predetermined image can be printed with a printer. In an area of the display unit 2 in the vicinity of the second input device 5, as shown in
When the photographer's finger is placed on the operation surface 5a of the second input device 5 and, for example, slid upwards, as shown in the drawing, the size of images in the displayed list 10 is increased, whereas, if the finger is slid downwards, the size of the images is decreased. For example, as shown in
By operating the fourth input device 7 in the vicinity of a menu mode indication 2f corresponding to the menu mode indication 2f, as shown in
Such a display apparatus with input devices according to this embodiment of the present invention is capable of clearly displaying images on the display unit 2 by preventing the display unit 2 from becoming dirty since the display unit 2 does not have to be touched for input.
Since a cursor is not displayed on the display unit 2, a complicated operation of moving a cursor in the X and Y directions is not required. In this way, operation is simple and easy.
According to this embodiment according to the present invention, the input devices 4 to 7 were disposed in all sections 3a to 3d of the frame 3. However, the input devices only need to be provided on the frame 3 at at least two adjacent sides orthogonal to each other in the X and Y directions (for example, on the right section 3b and the upper section 3c in
The input devices 3 to 7 according to the above-described embodiments are capacitance switches. However, the input devices 3 to 7 may be membrane switches having a plurality of moving contacts and a plurality of fixed contacts.
