DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention generally relates to an operation instruction input device for selecting a plurality of functions on an operation menu screen, and more particularly to an operation instruction input device applicable to an electronic camera device.

[0002]

2. Description of the Related Art In recent years, electronic cameras (also referred to as digital cameras), which convert a subject into image data by an electronic imaging function and record the image data on a recording medium, have become widespread. The electronic camera has a function of reading a captured image from a recording medium and reproducing the image on a screen of an LCD (liquid crystal display).

An electronic camera is provided with an operation instruction input device for performing an operation instruction such as selection of a photographing mode and a reproduction mode, and setting of various photographing conditions during a photographing operation. The operation instruction input device has a function of displaying an operation menu screen on the LCD and selecting a desired operation item (item indicating a function or condition) from a large number of selection items on the operation menu screen with a cursor operated by a cross key. Having. The operation instruction input device includes a menu switch for displaying the operation menu screen and a display switch (DISP switch) for switching ON / OFF of a through image display on the LCD in a shooting mode. (Including various input keys).

By the way, it is desirable that the operation instruction by the operation instruction input device can easily and accurately operate many functions. Conventionally, a device that generates a menu screen in which a plurality of operation modes are two-dimensionally developed, and has an operation unit that performs two-dimensional operation input of the menu screen, and that easily and accurately realizes advanced operation functions has been proposed. (See, for example, JP-A-11-331665).

[0005]

In order to easily and accurately perform many functions, a group of switches (including dials and various input keys) that are classified as much as possible are provided on the main body of the electronic camera. A desirable configuration is desirable. on the other hand,
In particular, in order to reduce the size of the electronic camera body, the space in which components such as switches can be arranged is limited, and thus a reduction in the number of components is required.

Therefore, in practice, the number of switches and the like is limited, and a method of selecting a target operation item from a large number of selection items on a menu screen displayed on the LCD is adopted. However, since the LCD is downsized and the display area for displaying the menu screen is also limited, the number of selection items that can be displayed at one time is limited. Therefore, a method of displaying a menu screen in which a large number of selection items are hierarchized as in the above-described conventional method is effective. The method of using the menu screen having such a hierarchical structure has an advantage that a large number of selection items can be selected and operated on a restricted display screen, but a cursor is moved or a screen is switched until a target operation item is selected. Complicated operations are required. In particular, even if the operation item is selected frequently, if the operation item is included in the selection item of the lower hierarchy, the operation of moving the cursor and switching the screen is always required, so that the operability is not good.

Therefore, an object of the present invention is to provide an operation instruction input device which can be applied to a device such as a small electronic camera and has excellent operability which can easily and accurately select a target operation item. To provide.

First instruction means for instructing the display means to display on the display means, and second instruction means for instructing the display means to first display the operation menu screen showing the lower hierarchy selection items It is.

[0010] With this configuration, the operation menu screen showing the selection item of the upper hierarchy among the many selection items arranged in the hierarchical structure is first displayed by the first instruction means. Therefore, an operation instruction for selecting, for example, a flash operation item in the shooting mode from the operation menu screen, and for selecting, for example, an automatic light emission item, which is a lower item of the flash operation item, from the operation menu screen indicating a lower hierarchy selection item Will be done.

On the other hand, an operation menu screen showing selection items of a lower hierarchy is first displayed by the second instruction means.
Therefore, in the above specific example, it is possible to first select the lower-level automatic emission item from the lower-level operation menu screen instead of the flash operation item as the upper-level item. In short, the operation menu screen including the target operation item can be displayed on the first display screen without switching the operation menu screen in order from the upper hierarchy. For this reason, when the operation item is an operation item with high frequency, an efficient operation instruction can be executed, so that the operability of the apparatus can be improved.

The second instruction means is also used as a switch (including a dial and an input key) for operating another function, thereby increasing the number of parts of the switch to be arranged in the apparatus without increasing the number of parts. An instruction function can be realized. Further, by applying the operation instruction input device of the present invention to, for example, an electronic camera device, it is possible to realize a small-sized electronic camera device having excellent operability.
