Claims (16)

Storage means for storing a plurality of images;
Image designation means for designating a reference image and a comparison image from a plurality of images stored in the storage means;
A comparison unit that acquires shooting date / time information of the specified reference image and the comparison image, and compares shooting date / time information of the reference image with shooting date / time information of the comparison image;
A determination unit that determines an operation when generating a temporal difference image based on a comparison result by the comparison unit;
An image processing apparatus comprising: a difference image generation unit configured to generate the temporal difference image from the reference image and the comparison image using the operation determined by the determination unit. The image processing apparatus according to claim 1, wherein the determination unit determines whether to subtract either the reference image or the comparison image from the other based on a comparison result by the comparison unit.   The difference image generation means deforms the comparison image with reference to the reference image designated by the image designation means, and generates the temporal difference image from the reference image and the comparison image transformed. The image processing apparatus according to claim 1.   The image designating unit is capable of displaying a list of images stored in the storage unit, and selects the reference image and the comparison image from the displayed list of images. The image processing apparatus described.   The image designation means can display a reduced image obtained by reducing the image stored in the storage means, and selects the reference image and the comparison image based on an instruction input for the displayed reduced image. The image processing apparatus according to claim 1.   The image designating unit can display the images stored in the storage unit in a predetermined order based on the shooting date and time information, and selects the reference image and the comparison image based on an instruction input for the displayed image The image processing apparatus according to claim 1, wherein: The determining means includes
When the shooting date and time indicated by the shooting date and time information of the comparison image is earlier than the shooting date and time indicated by the shooting date and time information of the reference image, the reference image is subtracted from the comparison image;
When the shooting date and time indicated by the shooting date and time information of the comparison image is more recent than the shooting date and time indicated by the shooting date and time information of the reference image , the calculation is determined to subtract the comparison image from the reference image. The image processing apparatus according to claim 1, wherein: Designating a reference image and a comparison image from the images stored in the storage means;
Obtaining shooting date / time information of the specified reference image and the comparison image, and comparing shooting date / time information of the reference image with shooting date / time information of the comparison image;
Determining a calculation for generating a temporal difference image based on a result of the comparison;
Generating the temporal difference image from the reference image and the comparative image using the determined calculation. An image processing method comprising: The step of determining an operation when generating the temporal difference image determines whether to subtract either the reference image or the comparison image from the other based on the comparison result. 9. The image processing method according to 8.   The step of generating the difference image includes deforming the comparison image using the designated reference image as a reference, and generating the temporal difference image from the reference image and the modified comparison image. Item 9. The image processing method according to Item 8.   9. The step of designating the reference image and the comparison image includes displaying a list of stored images, and selecting the reference image and the comparison image from the displayed list of images. The image processing method as described.   In the step of designating the reference image and the comparison image, a reduced image obtained by reducing the stored image can be displayed, and the reference image and the comparison image can be displayed based on an instruction input for the displayed reduced image. The image processing method according to claim 8, wherein: is selected.   In the step of designating the reference image and the comparison image, the stored images can be displayed in a predetermined order based on the shooting date and time information, and the reference image and the comparison are based on an instruction input for the displayed image. The image processing method according to claim 8, wherein an image is selected. In the step of determining an operation when generating the temporal difference image, when the shooting date and time indicated by the shooting date and time information of the comparison image is earlier than the shooting date and time indicated by the shooting date and time information of the reference image, Subtract the reference image from the comparison image;
When the shooting date and time indicated by the shooting date and time information of the comparison image is more recent than the shooting date and time indicated by the shooting date and time information of the reference image , the calculation is determined to subtract the comparison image from the reference image. The image processing method according to claim 8, wherein:   The control program for making a computer perform the image processing method of any one of Claims 8 thru | or 14.   A computer-readable storage medium storing a control program for causing a computer to execute the image processing method according to claim 8.
