[Example 1]
FIG. 1 shows a configuration block diagram of a digital camera having two optical systems of the first imaging optical system (10) and the second imaging optical system (20) in this embodiment.

  The first imaging optical system (10) includes a first lens (or lens group) (11) and a first image sensor (12). The first lens is detachable from the digital camera, and can be replaced with a lens with an arbitrary focal length range. A subject image is formed on the first image sensor (12) by the first lens (11). The imaging control circuit (13) controls the drive of the first image sensor (12), converts the image signal from the first image sensor to analog / digital, and sends it to the system control circuit (30). In the case of a zoom lens, the first lens (11) is driven in the optical axis direction by a zoom mechanism, and the angle of view can be changed by changing the focal length of the first lens. The first image sensor (12) is composed of a CCD or a CMOS, and converts the subject image into an image signal (first image signal) and outputs it.

  The second imaging optical system (20) includes a second wide viewing angle lens (21) and a second image sensor (22). A subject image is formed on the second image sensor (22) by the second wide viewing angle lens (21). The imaging control circuit (23) performs drive control of the second image sensor (22), converts an image signal from the second image sensor into analog / digital, and sends it to the system control circuit (30). The second wide viewing angle lens (21) is constituted by, for example, a wide angle lens called a panoramic lens. The panoramic lens is a lens capable of capturing light from all directions of 360 ° with the central optical axis as an axis at an angle of view shown in FIG. The panoramic image light captured by such a panoramic lens (21) is a circle (annular) image light. The second image sensor (22) is composed of a CCD or a CMOS, and converts the subject image into an image signal (second image signal) and outputs it.

  The system control circuit (30) receives the first image signal from the first imaging optical system (10) and the second image signal from the second imaging optical system (20), separates the luminance signal and the color signal, and performs edge processing. Various image processing such as γ correction, white balance adjustment, and JPEG compression processing are executed, and image data is output to a display circuit (38) such as an LCD, or output to a recording memory (37). The recording memory (37) is a memory detachable from the digital camera. If the memory capacity is insufficient, it can be replaced. The system control circuit (30) outputs either the first image signal or the second image signal or both the first image signal and the second image signal to the display circuit (38) or the recording memory (37) at the same time. .

Select whether to display two screens at the same time. When the second imaging optical system is selected, a field angle range that indicates the zoom position (field angle range) of the first lens (11) is created from the lens ID information and focal length information of the first lens (11). Then, it is combined with the second image data by a bold line, highlight, or blinking display, and output to the display circuit (38) or the recording memory (37). The lens ID information is information including model number information of the lens, and is used when creating a field angle range corresponding to a lens having a special field angle such as a fisheye lens. The user can visually recognize the shooting angle range of the first imaging optical system with respect to the second imaging optical system by visually recognizing the angle of view range frame indicating the zoom position.
