The imaging/reproducing switching button 1102 is set to the reproducing mode, and the menu button 2101 of the display part 300 is then pushed, whereby it is possible to transfer to the state in which the reproduction menu is displayed as shown in
The above mentioned menu items are described on the left side of
The imaging/reproducing switching button 1102 is set to the taking mode, and the menu button 2101 of the display part 300 is then pushed, whereby it is possible to transfer to the state in which the taking menu is displayed as shown in
The menu items are described on the left side of
The icon of a set-up item can be displayed in both the reproduction menu and the taking menu. Therefore, it is possible to shift to the set-up mode from both the taking mode and the reproducing mode.
When the menu is displayed, various functions are set in response to the button operation or the jog dial operation (step SA6). If an operation other than the operation concerning a menu is performed (step SA7), the menu mode is finished (step SA8).
According to the imaging apparatus of this invention, when the menu is displayed, the menu-type identification icon for identification of the present menu as the taking menu, the reproduction menu, or the set-up menu, is displayed in an inside region on the left side of the curved band-like image 2051, while the plurality of menu item icon images corresponding to the displayed menu-type identification icon image and the icon image for set-up are arranged on the curved band-like image 2051. Such an operation is performed mainly by a control flow in the display parts selector 211.
The menu-type identification icon image is kept displayed while a user selects the menu item to adjust or set the menu item. Thus, the user can easily recognize the purpose of the menu item being adjusted or set by the user.
The imaging apparatus of this invention is further described. In this apparatus, when the still image or moving image recorded in a hard disk or a memory card is transferred or received to or from an external apparatus, the still image can be transferred or received to or from a USB terminal through a USS controller. This case assumes that the external apparatus is a personal computer. It is also possible to transfer or receive an MPEG compressed moving image directly to or from an image recording/reproducing apparatus such as a DVD recorder through an interface. In general, when such image data is transferred to the DVD recorder, the MPEG compressed moving image is decoded on a camera side, and the resulting analog signal is output through a video terminal or S-terminal. The analog signal is re-compressed on the image recording/reproducing apparatus side to be stored. With this method, for example, it takes one hour to record the moving image recorded for one hour in the DVD recorder. However, in this case, the MPEG compressed moving image data can be transferred in a streaming form to the DVD recorder through a network as it is. Although the transfer time depends on a compression rate, it is possible to realize a speed of several tens of times faster than that of real time, and a high image quality can be maintained because re-encoding is not executed. For example, when the transfer time is 10 times faster than real time, it takes only six minutes to record the moving image recorded for one hour in the DVD recorder. When a LAN is used as a network, the moving image is sent or received to or from a LAN terminal through a LAN controller. In addition to the moving image data, the data containing the still image or audio data may be transferred to the DVD recorder.
As mentioned above, when the recording medium is a large capacity hard disk, since the number of recorded images is increased, it is necessary to feed or return the images at high speed. Therefore, in order to perform the feeding and returning of the images with no stress, the jog dial is used. The jog dial gives information of the rotation angle and rotation speed thereof to the controller for controlling the entire system. The controller may control the display speed of the image based on the information from the jog dial.
According to this invention, menu icons on the screen of the display part 300 are arranged concentrically in the jog dial. The iconized menu items are displayed on the screen. These icons are visually arranged concentrically in the jog dial. When the jog dial is rotated, the icons of the menu items are also rotated in synchronism with the rotation of the jog dial. The design representing the jog dial is provided between the jog dial and the icon items, whereby a user can intuitively understand that the menu can be selected or changed by rotating the jog dial.
When the difference of rotation radius is generated between the jog dial and the menu item icons, the user may feel that the rotation of the menu item icons is too fast or slow with respect to the rotation of the jog dial. In this invention, the user can set the relation of the rotation speeds of the jog dial and the menu item icons.
The user rotates the jog dial to select the setting of the rotation speed of the menu item icons from a menu on the screen. For example, the user selects “icon rotation speed” in the set-up menu, whereby he can select the items such as “faster”, “fast”, “intermediate”, “slow”, and “slower”, to set the rotation speed. The user confirms the selected result by rotating the jog dial. If the user does not like the rotation speed, he can change the setting to select a suitable speed. The controller stores the setting, and controls the rotation of the menu item icons on the basis of the input of the jog dial and the setting value.
In addition, the menu-type identification icon (design) representing the kind of menu is displayed, whereby the user can easily understand the kind of the menu being displayed.
The jog dial and the curved band-like image are concentrically arranged, and their rotations are synchronized, whereby the usability and the operational feeling are improved. The design representing the jog dial is displayed, whereby the user can intuitively understand that the menu can be selected or changed by rotating the jog dial. In addition, the design representing the kind of the menu is displayed, whereby the user can easily understand the kind of the menu.
