Problems solved by technology

[0007] However, when recording moving images before and after still image shooting, there is a problem that when a subject with little change, such as scenery, is saved as a moving image, although the value of saving it as a moving image is low, but still consumes too much recording media

Embodiment Construction

[0040] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0041] FIG. 1 is a diagram illustrating a basic configuration of an imaging device 100 according to an embodiment of the present invention. As shown in FIG. 1 , the imaging device 100 includes an imaging unit 110 , a driver 120 , a recording start / stop switch 130 , a mode switch 140 , a signal processing circuit 150 , a display device 160 , and an external recording medium 170 .

[0042] In addition, FIG. 2 is a diagram illustrating an appearance of the imaging device 100 by way of example. In the imaging device 100, as shown in FIG. 2, a recording start / stop switch 130 (shutter button), a mode changeover switch 140 (mode dial) and a display device 160 are arranged, and the user can control the recording start / stop switch 130, the mode changeover switch 140 to operate and confirm the display content of the display device 160 . In addition, a key switch 180 for menu op...

Abstract

The invention discloses a signal processing circuit and an image shooting apparatus for determining saving format according to set conditions so as to restrain consumption of recording medium and automatically judge user-expected shooting mode when recording dynamic images before and after the static images. The signal processing circuit includes: a buffer memory(154) for temporarily storing a shot image; and a moving-picture detection device(151) for detecting whether or not the shot image is a moving picture. Whether to store the shot image in the buffer memory(154) as a moving memory, as a still picture, or as both a moving picture and a still picture is determined according to the detection result of the moving-picture detection device(151).

Description

technical field [0001] The present invention relates to a signal processing circuit for processing both still images and moving images. Background technique [0002] In recent years, even digital picture cameras have become capable of recording movies with the same high quality as digital video cameras. In addition, an image processing device capable of capturing still images in moving image photography has also been proposed. For example, an image processing device that changes the compression method of still images and moving images and stores them in different areas of the recording medium and can improve the resolution of still images captured in moving image photography (see, for example, Patent Document 1 ). [0003] Also, an electronic camera has been proposed that automatically captures moving images before and after still image shooting in order to record the surrounding conditions of a subject before and after still image shooting (see, for example, Patent Docume...
