Description

  The present invention relates to a camera having a still image shooting function and a still image and moving image display function.

  In recent years, cameras having a still image recording function for recording a subject image projected on a solid-state imaging device through an optical system such as a lens as electronic data have become widespread. Further, even in an electronic apparatus typified by a mobile phone, a still image recording function is realized by incorporating such a camera.

  Such an electronic device incorporating a camera generally includes display means represented by an LCD (Liquid Crystal Tal Display; liquid crystal display), and this display means is a moving image output from the camera before taking a still image. Can be used as a finder by displaying in real time, or an image recorded after still image shooting can be reproduced and displayed to check the recorded image.

  According to the display means of such a camera or electronic device, the photographed still image is generally displayed for a certain period of time in order for the photographer to check the recorded image immediately after the still image is photographed. However, the display function of another viewfinder, that is, the function of displaying a moving image in real time is stopped during the display time of the recorded image, so the viewfinder is viewed while checking the still image as the recorded image. However, a new image cannot be taken, and there is a problem of lack of convenience.

  As a method for solving such a problem, the technique described in Patent Document 1 includes a switch, and when this switch is not pressed, a recorded image previously captured on the display unit is fixed after capturing a still image. It is disclosed that when the time is displayed and this switch is pressed during still image shooting or during recording image confirmation after the end of still image shooting, the display on the display means immediately becomes a real-time display of a moving image as a viewfinder. With the configuration shown in Patent Document 1, it is possible to switch to real-time display of a moving image as a finder whenever a switch is operated, and the convenience of the camera is improved, such as not missing a photo opportunity. .

As another conventional technique, Patent Document 2 includes an example in which a still image is also displayed in a moving image displayed on a display unit, and still images are captured in a state where moving images are captured by continuous shooting. When shooting of a still image is instructed by pressing the image release switch, a flag is added to the image at the time when still image shooting is instructed in the moving image recorded on the memory card, and the moving image is played back after the shooting is completed. A technique for displaying a still image to which a flag is added in parallel with the display of a moving image as a so-called picture-in-picture in the moving image is disclosed. According to the configuration shown in Patent Document 2, it is possible to simultaneously check a specified still image while displaying a specified still image as a part of a moving image during shooting of a so-called moving image by continuous shooting. Is.

The switch operation for obtaining is also complicated. Further, in the case of a momentary photo opportunity during the confirmation of the recorded image, the real time display of the moving image by the switch operation may not be in time, which is insufficient as a finder function.

  In addition, in the apparatus described in Patent Document 2, it is disclosed that simultaneous display of a moving image and a still image is performed at the time of playback display after the end of shooting, but a part of the moving image being shot is missing. A still image is displayed, and it is only possible to display a still image on a part of a reproduced moving image after shooting, and the convenience as a camera finder when shooting a still image is insufficient.

  The present invention has been made in view of the above points, and includes a display unit having a still image shooting function and a still image and moving image display function, and requires an additional switch as in the prior art. It is an object of the present invention to provide a camera that can display a still image that has been taken at the same time while continuously displaying a moving image as a viewfinder image at the time of still image shooting.

  The camera of the present invention stores an image sensor that outputs a subject image as a video signal, signal processing means for converting the video signal into moving image data, and stores the moving image data or data corresponding thereto as accumulated image data. Storage means; decoding means for reading out the stored image data and performing decoding processing to generate playback still image data; storing the stored image data in the storage means by turning on the first switch; Control means for outputting an instruction for generating still image data, display means for displaying an image in accordance with an input drive signal, first image area for displaying moving image data output from the signal processing means, and the decoding means Display control means for generating a drive signal for displaying on the display means an image including a second image area for displaying reproduced still image data output by And, a configuration with.

  According to the present invention, the camera output moving image is continuously displayed in the first image area as a finder image even when capturing a still image with a simple configuration that does not require an additional changeover switch or the like as in the prior art. It is possible to provide a camera capable of simultaneously displaying captured images in the second image area while continuing.

  The essence of the present invention comprises a display means having a still image shooting function and a still image and moving image display function, and continuously displays a moving image as a finder image as a camera output moving image during still image shooting.

  In the electronic apparatus of FIG. 9, for example, the camera function is turned on by the camera key 91d, and then the first switch 19a is operated, whereby the camera output moving image is continuously displayed as a finder image in the first image area 171. At the same time, the playback still image can be displayed in the second image area 172.

  In addition, by operating the second switch 19b and the third switch 19c, a playback still image to be displayed in the second image area 172 can be arbitrarily selected from the stored image data 102 stored in the storage means 14. Further, the stored image data 102 corresponding to the image displayed in the second image area 172 can be erased from the storage means 14 by operating the fourth switch 19d.

  As described above, in an electronic apparatus equipped with a camera according to an embodiment, real-time display of a moving image output from the camera and a captured playback still image are always obtained without performing any special operation during still image shooting. In addition, since it is possible to easily confirm and erase any shot still image, it contributes to improving the convenience of an electronic device equipped with a camera.

  FIG. 9 describes the electronic device (in this case, a mobile phone device) having a camera as described above, and further includes an information terminal device, a mobile station device, and this mobile station device as well as a telephone device. A mobile communication system can also be equipped with this camera, and the same effect can be obtained.

  The present invention is suitable for use in a camera that displays a still image captured by a moving image display finder.
