Abstract

PROBLEM TO BE SOLVED: To easily switch to 3D imaging during 2D imaging.SOLUTION: An imaging apparatus has: imaging means for outputting three-dimensional image data and two-dimensional image data; storage means for temporarily storing the three-dimensional image data; recording means for recording the three-dimensional image data and the two-dimensional image data to the recording medium; and control means which reads the three-dimensional image data stored by the storage means and records it to the recording medium. The control means stores, while recording the two-dimensional image data, image data of the same dimension to the storage means, and controls the recording means so that when instructions for switching from recording of the two-dimensional image data to recording of the three-dimensional image data are given by a user while recording the two-dimensional moving image data, the three-dimensional image data stored to the storage means a prescribed time earlier from the switch instructions is recorded in place of the two-dimensional image data.

Description

  The present invention relates to an imaging apparatus.

  In recent years, 3D video content platforms such as 3D movies, home AV equipment, broadcasting / IPTV, etc. have been spreading, and development of equipment that handles 3D data is also being promoted in digital cameras and digital video cameras.

  For example, a liquid lens is used, and 2D shooting and 3D shooting can be switched by a single imaging device by electronic control (see Patent Document 1).

Japanese Patent Application No. 2008-527754

  However, in the above conventional example, when switching between 2D shooting and 3D shooting, the shot image cannot be recorded by the shooting method switched only from the moment, so the user wants to record the shot image in 3D. When there was a scene, switching from 2D shooting to 3D shooting was slow, and there was an event that the scene could not be recorded.

  An object of the present invention is to provide an apparatus that can easily switch to shooting of a three-dimensional image even during shooting of a two-dimensional image.

  The configuration of the imaging apparatus according to the present invention includes an imaging unit that outputs three-dimensional image data and two-dimensional image data, a storage unit that temporarily stores the three-dimensional image data, and the three-dimensional image. Recording means for recording data and the two-dimensional image data on a recording medium; and control means for reading out the three-dimensional image data stored in the storage means and recording the data on the recording medium. Storing the two-dimensional image data in the storage means during the recording of the two-dimensional image data, and recording the two-dimensional image data by the user during the recording of the two-dimensional moving image data. When an instruction to switch to image data recording is given, the three-dimensional image data stored in the storage means for a predetermined time before the instruction to switch is replaced with the two-dimensional image data. And controlling the recording device to record Te.

  According to the present invention, even when a two-dimensional image is being captured, it is possible to easily switch to capturing a three-dimensional image.

Selection / switching of shooting from 2D to 3D and 3D to 2D, selection / setting of REC / pre-REC, shutter button and zoom button when performing imaging recording, power ON / OFF, etc. It is composed of a number of switch groups such as menu select or key switch. The display unit 106 is an interface that receives a monitor function of a captured video or a reproduced video, displays various management data to a user, or gives an operation command instruction. Also, the I / F 107 is a predetermined format signal such as IEEE 1394, USB (Universal Serial Bus), HDMI (High-Definition Multimedia Interface), analog video signal (Audio / Video), etc. via an external terminal or a radio. It is an interface system that realizes the transmission / reception function.

  The temporary recording medium 103 is a memory that is time-shared in each process of the CPU 101, and temporarily stores photographing data. The recording medium 104 is controlled to write and read data via the CPU 101 and stores captured image data.

  FIG. 2 is a flowchart showing the operation of the imaging apparatus. In step S <b> 201, the CPU 101 starts shooting via the imaging unit 104. In step S202, the CPU 101 records the 2D captured image data captured in S201 as the REC on the recording medium 102, and at the same time, the CPU 101 acquires 3D captured image data via the imaging unit 104 as the pre-REC, and temporarily stores the data. Recording is performed on the recording medium 103. Here, the pre-REC is to temporarily capture image data and record the image data that was buffered when recording was started.

  In step S203, if the CPU 101 is requested to change the shooting method from 2D to 3D via the operation unit 105 or the I / F 107, the CPU 101 changes the shooting method from 2D to 3D, and the process proceeds to step S204. When there is no request to change the shooting method from 2D to 3D and the operation is continued in 2D, the CPU 101 continues the shooting method in 2D, and the process proceeds to step S207. In step S204, the 3D photographed image data recorded from the time of switching to a predetermined time before the CPU 101 pre-REC in step S202 and recorded in the temporary recording medium 103 is recorded in the recording medium 102. Further, the CPU 101 ends the pre-REC after the recording is completed.

If the pre-REC is not executed through step S308, the process proceeds to step S302. In step S306, it is confirmed whether it is necessary to record the image data of the pre-REC 3D or 2D shooting method not selected as the shooting method. If it is necessary to record image data of an imaging method that is pre-REC and not selected, the process proceeds to step S307. On the other hand, if it is not necessary to record image data of an imaging method that has not been selected, the process proceeds to step S302.
