Description

  The present invention relates to an imaging apparatus capable of mirror-up shooting, and more particularly to display during mirror-up shooting in remote shooting.

  Conventionally, the display of the mirror-up state and the setting state at the time of mirror-up shooting is output to the display device of the camera body. When the mirror-up shooting is set, the mirror-up shooting mark is turned on when the mirror-up shooting is set, and the mirror-up mark blinks during the mirror-up shooting to notify the photographer that the shooting is in progress. When mirror-up shooting is disabled and mirror-up shooting is not enabled, the mirror-up mark is turned off. In remote shooting, when the photographer is away from the camera body, it is difficult to immediately determine the mirror-up shooting status.

  For example, Patent Document 1 discloses display control of a mirror up mark.

It is a figure which shows the display form of a mirror up mark.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a system configuration diagram according to an embodiment of the present invention.

  Example 1 showing the embodiment of the present invention will be described below.

  Fig. 1 shows a schematic diagram of an interchangeable lens digital camera.

  The interchangeable lens 1 generally includes a zoom lens 11 for changing a focal length, a diaphragm mechanism 12 for controlling brightness, and a focus lens 13 for focusing on a subject. The interchangeable lens 1 is configured such that the lens-side mount 14 can be mechanically joined to the mount portion 27 of the digital camera 2. The digital camera 2 reflects light that has passed through the lens with a half mirror 21 and forms an image at the position of the focusing plate 24. The light imaged on the focus plate 24 is inverted by the prism 25 and can be observed as an erect image through the eyepiece lens 26.

  Further, at the time of shooting, the half mirror 21 jumps up, the shutter 22 opens, and the light passing through the lens 1 forms an image on the image sensor 23.

  A contact group 15 is incorporated in the mount portion 14 of the interchangeable lens 1. The contact group 15 is a contact (not shown) for supplying power from the digital camera body and performing communication. The contact group 15 is divided into applications such as power supply, ground, transmission, reception, and clock.

  The mount portion 14 of the interchangeable lens 1 is joined to the mount portion 27 of the digital camera 2 so that the contact groups 15 in the mount portion 14 and the connection terminals in the contact group 28 in the mount portion 27 are connected to each other. .

  As a result, power is supplied from the digital camera 2 to the interchangeable lens 1 via the connection terminal, and communication is started between the interchangeable lens 1 and the digital camera 2.

  Next, FIG. 2 shows an internal configuration of the digital camera 2.

  The image sensor 23 is a sensor such as a CCD or a CMOS, and the light imaged on the image sensor 23 is converted into an amount of electric charge corresponding to the amount of incident light in each pixel in the image sensor 23.

  The signal generated by the timing generator 32 drives the image sensor 23, transmits the charge accumulated in the sensor, and is sequentially converted into a voltage signal.

  The converted voltage signal is sampled by correlated double sampling 30 (hereinafter referred to as CDS) and converted to a digital signal by an A / D converter 31.

  The image data converted into the digital signal is input to the IC 33, first enters the WB circuit 33 a for calculating data for white balance with respect to the data, and is temporarily stored in the memory 1 of 35.

  The data stored in the memory 1 of 35 is input again to the IC 33 and subjected to three image processes.

  First, image data converted into a digital signal is converted into lossless compressed RAW data in a lossless compression circuit 33d that performs lossless compression (reversible compression) as it is, and sent to the CPU bus 34.

  In addition, the image data converted into digital signals is downsampled by reducing the bandwidth by averaging the RAW data within the block or applying a low-pass filter as shown in Fig. 7, for example, and the original image size is reduced. In order to be converted into a smaller thumbnail image, the RAW thumbnail circuit 33 c performs thinning processing and sends it to the CPU bus 34.

  Finally, in order to create an image for jpeg compression, image processing is performed in the image processing circuit 33b, and YcbCr output as a result is raster-block converted, and jpeg compression is performed in the jpeg compression circuit 33e. It is sent to the CPU bus 34.

  Immediately after the power is turned on, the CPU 36 initializes the digital camera 2 and starts communication with the interchangeable lens according to the program in the memory 2 of 37.

  In addition, the CPU stores the image data output to the CPU bus 34 as the captured image data once in the memory 1 of 35 and finally writes it in the external memory 39 via the interface circuit 38.

  A switch 40 connected to the CPU 36 is a release switch. When the switch 40 is pressed, the above-described photographing operation is performed, and an image is written in the external memory 39.

  When the mirror-up shooting setting is enabled and mirror-up shooting is performed, the half mirror 21 only jumps up when the release switch is pressed in order to prevent blurring of the digital camera due to vibration generated when the half mirror jumps up. No shooting operation is performed, and the half mirror 21 is kept raised even when the release switch is released. When the release switch is pressed again, a shooting operation is performed and an image is written in the external memory 39.

  Next, a method for displaying a mirror-up mark indicating a mirror-up setting and a state of mirror-up shooting in a digital camera connected to a computer via the external interface of the present invention will be described.

  The display of the mirror up mark is displayed on a display 41 connected to the computer 40.

  FIG. 3A shows a screen panel 310 that displays the mirror-up state on the display 41 connected to the computer. During remote shooting, a mirror-up mark is displayed on the screen panel 310 together with shooting setting displays such as a shooting mode 311, a drive mode 312, and an AF mode 313.

  The mirror-up mark display 314, the mirror-up mark display 315, the mirror-up mark display 316, and the mirror-up mark display 317 shown in FIGS. 3a, 3b, 3c, and 3d are the mirror-up mark display type and the mirror-up mark according to the present invention. The display state of the mirror-up mark is selected according to each mirror-up setting state in the mirror-up shooting in the remote shooting, and the display state of the mirror-up mark is switched depending on the state of the mirror-up shooting.

  The display state of the mirror-up mark is as follows depending on the mirror-up shooting setting and the mirror-up shooting state.

  The mirror-up mark display 314 indicates the mirror-up mark lighting state, and is set to “execute” mirror-up shooting, which means that mirror-up shooting is possible.

  The mirror-up mark display 315 represents a display state of the mirror-up mark being light, and the mirror-up shooting setting is in an “unset (not set)” state, which means that the mirror-up shooting can be set.

  A mirror-up mark display 316 indicates that the mirror-up mark is blinking and means that mirror-up shooting is being performed.

  The mirror-up mark display 317 indicates that the mirror-up mark is turned off, and means that the mirror-up shooting is not effective.

  The display form of the mirror-up mark depending on the mirror-up shooting and the state of the mirror-up setting is not limited to the example shown in the first embodiment. For example, the color is changed instead of the blinking display of the mirror-up mark. Alternatively, an alternative display method of reducing the mark display instead of the mirror-up mark off display may be applied.

  FIG. 4 is a mirror-up display control flowchart of the present invention, and this program is executed by a computer.

  The digital camera 2 is connected to the computer 40 via the interface 38. The computer 40 can communicate with the digital camera 2 to obtain information corresponding to Table 1 inside the digital camera 2.

  In step S101, both the digital camera 2 and the computer 40 are powered on and energized to be operable.

  In step S <b> 102, the current setting information of the computer 40 is notified from the computer 40 to the digital camera 2, and the digital camera 2 receives the setting state of the computer 40.

  The setting information received from the digital camera 2 in step S102 is each information of the shooting mode setting state, the mirror-up shooting setting state, the live view state, and the mirror-up display state.

  The camera setting information is notified from the digital camera 2 to the computer 40 when the camera state is changed by the photographer or when the setting from the computer 40 to the digital camera 2 is changed.

  In step S103, it is determined whether the shooting mode of the digital camera 2 is capable of mirror-up shooting. If the answer is negative (NO), the mirror-up mark is turned off on the remote shooting screen (S104). If YES, the process proceeds to step S105.

  In step S105, the live view state in which the digital camera 2 cannot perform mirror-up shooting is determined. If the answer is negative (NO), the mirror-up mark display is turned off on the remote shooting screen, and if the answer is positive (YES). Proceed to step S107.

  In step S107, it is determined from the setting information of the digital camera 2 that mirror-up shooting has not been set. If the answer is negative (NO), a display indicating that no mirror-up mark has been set is displayed on the remote shooting screen. (S108) is performed, and if affirmative (YES), the process proceeds to step S109.

  In step S109, the mirror-up display information is determined from the display information of the digital camera 2, and when the answer is negative (NO), the mirror-up mark is turned on on the remote shooting screen (S110). If (YES), the mirror up mark is turned off (S110). After updating the mirror-up mark display, it is confirmed in step S112 whether or not a setting state update notification has been issued from the digital camera. If there is an update (YES), the process returns to step S103 and the mirror-up mark update process is performed again. If the communication is disconnected in step S113, the power is turned off in step S114 and the process ends.
