Problems solved by technology

[0006] However, in conventional photographing devices, the number of shots required for shooting is clear. However, the user must be aware of the remaining number of photographable shots displayed on the display device attached to the photographing device. In order to completely capture a panoramic image, the user must Ensure that the number of shots required for photography is less than the remaining number of shots available
There is such a problem in this job, and promptly, for the user, increased burden, simultaneously, if negligence, then can become 0 in the remaining amount of recording medium during panoramic image photographing, and have to stop photographing

Embodiment 1

[0022] In the following embodiment 1, a case where shooting is performed in a stitching mode in which several captured images are connected to form a panoramic image, especially in a 2×2 stitching mode, will be described as an example.

[0023] FIG. 1 shows the system configuration of a digital camera in this embodiment. In this figure, 1 is a digital camera, 2 is a photographic optical system, 3 is a lens, 4 is a CCD, 5 is a CDS / AGC, 6 is an A / D converter, 7 is a signal processing device A, and 8 is a V-driver. , 9 is a timing generator (hereinafter referred to as TG), and 10 is a signal processing device B.

[0024] In addition, 11 is a data bus, 12 is a CPU bus, 13 is a nonvolatile memory such as ROM, 14 is a CPU, 15 is a compact flash memory (hereinafter referred to as CF) for recording image data, 16 is a user interface having an operating member, 17 is a display controller, 18 is VRAM, 19 is a volatile memory such as DRAM, and 20 is a liquid crystal monitor.

Embodiment 2

[0051] In the following embodiment 2, the case of shooting in the auto exposure bracketing mode will be described as an example, wherein the auto bracketing mode refers to shooting the same image multiple times while changing the exposure by several steps. Note that the configuration of the digital camera in this embodiment is the same as that described in Embodiment 1 above, and its detailed description will be omitted.

[0052] Figure 4 Represents a flowchart for explaining the operation of the AEB mode. First, it is assumed that the shooting setting is selected with the menu button 107 and the AEB mode is selected on the liquid crystal display 109 . Assume that the auto bracketing mode in this embodiment is a mode in which exposure is changed in 3 levels and 3 or 5 images are acquired at a time. Hereinafter, a case of three sheets will be described.

[0053] In addition, the reason why 3 or 5 images are acquired here is because it is suitable for changing the exposure c...

Embodiment 3

[0064] In Embodiment 1 and Embodiment 2 above, an example in which the image data size and the recording compression rate are automatically set has been described. But it can also be, when in image 3 Step S204 or Figure 4 When it is determined in step S304 that the remaining capacity of the recording medium is not enough to capture all of the stitched image or the AEB image, a warning is given to the user.

[0065] In this case, by reducing the size of the image data or increasing the recording compression rate, the full image can be captured, and a more convenient shooting environment can be provided by displaying a suggested screen for that content.

Abstract

Image pickup apparatus, image pickup method, program and storage medium. To eliminate the burden that a user himself / herself guarantees in advance that the number of sheets required for photographing is smaller than the number of remaining photographable sheets in a mode for photographing at least two sheets or more. In the case of taking a photograph in a mode for photographing at least two sheets or more, such as in a stitch mode and an auto bracket mode, the number N of sheets required for photographing in the mode is determined, the number R of remaining photographable sheets is calculated, and when the number N of sheets required for photographing is smaller than the number R of remaining photographable sheets, an image data size is reduced and an image data recording compression rate is increased.

Description

technical field [0001] The present invention relates to a photographing device such as a digital camera, and more particularly to a photographing device capable of photographing in a mode of capturing at least two images. Background technique [0002] Digital cameras that record images as digital data, unlike silver halide cameras that record on film, are easy to edit and communicate images, and are used in a wide range of applications. Users can browse, delete, or re-shoot the captured images on the spot without waiting for the film to develop. In particular, when users share images taken by themselves, the images can be relatively easily distributed to other users by sending or receiving files based on electronic data without printing the images. [0003] Furthermore, there is also a panorama image synthesis technique, that is, several images are taken and then synthesized, thereby equivalently generating a high-angle, high-quality image. In the panorama image synthesis ...
