Description

  The present invention relates to an imaging apparatus equipped with a touch panel that detects a touch operation, and more particularly to startup control at startup.

  In recent years, with retractable digital cameras, the photographic lens has been increased in magnification and field of view, and has an optical magnification of 5 times and a focal length of 28 mm in terms of 35 mm film when the wide end is set. Models with a photographic lens are also appearing.

  When the magnification of the taking lens is increased with a retractable digital camera, the amount of extension of the lens barrel increases. For this reason, if a waterproof case is designed corresponding to a retractable digital camera provided with a photographic lens having a high magnification and a high angle of view as described above, there is a problem that the lens barrel portion is enlarged.

  For this reason, when the power is turned on while being accommodated in the waterproof case, the amount of extension of the lens barrel is limited (see Patent Document 1).

JP 2010-12816 A

  However, in the invention described in Patent Document 1, the power supply SW is not used when the user does not intend when the device is not carried in a waterproof case for underwater photography and is carried in a bag or the like alone. When it is pushed, the lens barrel is pulled out and the lens barrel is pulled out, so that the lens barrel may hit another stored item in the bag and damage the lens barrel.

  The present invention has been made in view of the above points, and by controlling the lens barrel extension when the power is turned on, the lens barrel can be attached to the lens barrel when the power is turned on without being intended by the user, such as in a cage. An object is to provide an imaging device capable of reducing damage.

In order to achieve the above object, an imaging apparatus of the present invention provides:
An accepting means for accepting an activation operation;
A touch operation detecting means for detecting a touch operation;
When the activation operation is accepted, if the touch operation is not detected by the touch operation detection means, the lens barrel is controlled to be extended according to the activation operation, and when the activation operation is accepted, When the touch operation is detected by the touch operation detection unit, the control unit is configured to control the lens barrel so that the lens barrel is not extended according to the activation operation.

  According to the imaging apparatus of the present invention, when a touch operation is performed on the touch panel when the activation operation is received, the lens barrel is controlled so as not to be extended when the touch operation on the touch panel is detected. Thus, damage to the lens barrel can be reduced when the power is turned on without the user's intention.

It is a flowchart shown about the starting process of an imaging device. It is a composition conceptual diagram concerning other embodiments of the present invention.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 shows a schematic configuration diagram of a digital camera of the present embodiment. In FIG. 1, 1 is a digital camera body, 2 is a power supply SW for turning on the power to the body, and 3 is a release switch. Reference numeral 4 denotes a liquid crystal panel with a touch panel for displaying captured / reproduced images / shutter speed and aperture numerical value photographed number information and performing a KEY operation. Reference numeral 5 denotes a mode switch for switching modes such as shooting / reproduction.

  Although not shown in FIG. 1, a retractable lens barrel that retracts / extends a lens barrel provided with a photographing lens is also included.

  FIG. 2 is a block diagram showing the configuration of the control unit of the digital camera shown in FIG. In the figure, 11 is a power supply unit for supplying voltage to the digital camera body for operating the digital camera 1, 12 is a CPU for controlling the entire digital camera, and 13 includes a CCD for capturing an image. An imaging unit 14 is an image processing unit that processes captured images, 15 is a storage unit that stores image data, 16 is a liquid crystal display unit for notifying the outside of the state of the captured image display and the digital camera body, and 17 Is a touch panel operation unit that performs operations on the apparatus in accordance with operations from the touch panel, 18 is an operation unit that performs operations on the apparatus, 19 is a lens barrel drive control unit that controls the lens barrel, and 20 is The lens barrel drive unit drives the lens barrel unit under the control of the barrel drive control unit.

  Although not shown in FIG. 2, the CPU 12 is further connected to various circuits and the like necessary for photographing and reproduction of the digital camera in FIG. 1, and the CPU 12 is stored in a ROM (not shown). Perform predetermined program operation control.

  The startup process of the imaging apparatus having the above configuration will be described with reference to the flowchart shown in FIG.

  After receiving the power activation operation, in step 101, it is determined whether or not the mode switch 5 is pressed. If the mode switch 5 is in the pressed state in step 101, the process proceeds to step 109, where it is determined that the waterproof case is in the housed state, and the underwater mode is started in which the operation from the liquid crystal panel 4 with the touch panel is not accepted. If it is determined in step 101 that the mode switch 5 is not pressed, the process proceeds to step 102 and touch panel detection is started.

  Next, in step 103, it is determined whether there is a touch operation on the touch panel of the liquid crystal panel 4 with a touch panel. If it is determined in step 103 that there is no touch operation on the touch panel of the liquid crystal panel 4 with a touch panel, the process proceeds to step 107 and the lens barrel of the retractable lens barrel is extended to perform normal startup. When it is determined in step 103 that there is a touch operation on the touch panel of the liquid crystal panel 4 with a touch panel, a touch state warning such as “touched” is displayed on the liquid crystal panel 4 with a touch panel.

  In this embodiment, in step 101, it is determined that the waterproof case is housed depending on whether the mode switch is pressed, and in step 109, the underwater mode is started. If the button is pressed for more than a certain time, it may be determined that the waterproof case is stored and activated as an underwater mode.

  In step 104, a warning indicating the touch state is given. In step 105, it is determined whether a predetermined time has elapsed since the touch state warning was displayed. If it is determined in step 105 that the predetermined time has elapsed, the process proceeds to step 108, where it is determined that the touch state unintended by the user continues, and the lens barrel extension control is not performed, and the power OFF process stored in the ROM is performed. Follow the instructions to turn off the power. If it is determined in step 105 that the predetermined time has not elapsed since the touch state warning display is performed, the process proceeds to step 106 and it is determined whether or not touch detection is lost on the touch panel of the liquid crystal panel 4 with a touch panel.

  If it is determined in step 106 that there is touch detection on the touch panel of the liquid crystal panel 4 with a touch panel, the process returns to step 105 and the processes up to step 106 are repeated. If it is determined in step 106 that there is no touch detection on the touch panel of the liquid crystal panel 4 with a touch panel, the process proceeds to step 107, and the user touches the liquid crystal panel 4 with a touch panel in the touch state such as “touched” on the touch panel in step 104. Since the warning display is recognized and the touch panel touch panel is removed from the liquid crystal panel 4 with a touch panel, the lens barrel is controlled to start up normally.

  In the present embodiment, when the touch detection is performed in the touch-detectable area of the touch panel on the liquid crystal panel 4 with the touch panel in step 103, a touch state warning display such as “touched” is displayed on the touch panel. However, as shown in FIG. 4, when the user grips the digital camera body 1, an area touched by the user's finger or the like is handled in advance as being outside the determination area, and the touch panel-equipped liquid crystal panel 4 is within that area. Even when touch detection is performed, the lens barrel may be controlled to start the lens barrel and perform normal activation.
