Control method, control apparatus and control program for photographing apparatus
First Claim
1. A control method provided for a photographing apparatus having a first mode for generating an output image by taking one input image and a second mode for generating an output image by taking a plurality of input images successively without using a binning function, the control method comprising:
- comparing at least one of a first exposure time, which is an exposure time of a photographing operation to take an input image when said photographing operation is to be carried out in said first mode, and a second exposure time, which is an exposure time of a photographing operation to take a plurality of input images without using said binning function when said photographing operation is to be carried out in said second mode, with a first threshold value;
determining whether or not said first exposure time is equal to or shorter than said first threshold value;
making a first decision to take an image in said first mode if said first exposure time is equal to or shorter than said first threshold value;
selecting a second threshold value different from said first threshold value; and
making a second decision to take an image in said second mode if said second threshold value is equal to or shorter than said first threshold value.

Abstract
The present invention relates to a control method of a photographing apparatus, the photographing apparatus and a control program, which are capable of automatically determining a photographing mode capable of generating a sharper image. If a first exposure time is equal to or shorter than a first threshold value, a control circuit 18 makes a decision to take an input image in a first mode. The first exposure time is an exposure time required for taking one input image on the assumption that a photographing operation is carried out in the first mode for generating one output image by taking one input image. If the first exposure time is neither equal to nor shorter than the first threshold value, on the other hand, the control circuit 18 makes a decision to take a plurality of input images in a second mode provided that a second exposure time is equal to or shorter than a second threshold value. The second exposure time is an exposure time required for taking each of the input images successively on the assumption that a photographing operation is carried out in the second mode for generating one output image by taking the input images successively. The present invention can be applied for example to a digital camera.

15. A control apparatus provided for a photographing apparatus having a first mode for generating an output image by taking one input image and a second mode for generating an output image by taking a plurality of input images successively without using a binning function, wherein said control apparatus comprises a control circuit configured to compare at least one of a first exposure time, which is an exposure time of a photographing operation to take an input image when said photographing operation is to be carried out in said first mode, and a second exposure time, which is an exposure time of a photographing operation to take a plurality of input images without using a binning function when said photographing operation is to be carried out in said second mode, with a first threshold value;
-
determine whether or not said first exposure time is equal to or shorter than said first threshold value; make a first decision to take an image in said first mode if said first exposure time is equal to or shorter than said first threshold value; selecting a second threshold value different from said first threshold value; and make a second decision to take an image in said second mode if said second threshold value is equal to or shorter than said first threshold value.

16. A non-transitory computer-readable medium tangibly storing a control program to be executed by a computer for controlling a photographing apparatus having a first mode for generating an output image by taking one input image and a second mode for generating an output image by taking a plurality of input images successively without using a binning function, the control program comprising steps of
comparing at least one of a first exposure time, which is an exposure time of a photographing operation to take an input image when said photographing operation is to be carried out in said first mode, and a second exposure time, which is an exposure time of a photographing operation to take a plurality of input images without using said binning function when said photographing operation is to be carried out in said second mode, with a first threshold value; -
determining whether or not said first exposure time is equal to or shorter than said first threshold value; making a first decision to take an image in said first mode if said first exposure time is equal to or shorter than said first threshold value; selecting a second threshold value different from said first threshold value; and making a second decision to take an image in said second mode if said second threshold value is neither equal to or shorter than said first threshold value.
