Program recording medium, image processing apparatus, imaging apparatus, and image processing method

A non-transitory computer readable program recording medium storing, for a computer having a data reading section which reads data of an image, a calculating section, and an operating section, a program comprising:

• a first step reading, into the calculating section, data of an object image group which includes a plurality of specified images and interpolation images having each been generated by interpolating images of the object image group, respective images in the object image group being still images continued in a time base direction, and reading addition rate data recorded in correspondence with each of the specified images and indicative of an addition rate of images to be added to each of the specified images, in case of generating composite images by adding at least one or more images to be added to the specified images, the images to be added being different in the time base direction;
• a second step generating a plurality of the composite images using data indicative of a specified image at a time of compositing the image and addition rate data at the time of compositing the image;
• a third step reproducing and outputting the plurality of the composite images along time series;
• and
• a fourth step displaying and outputting, as a still image, the specified image, which is an image used for generating the composite images being reproduced, when receiving an instruction to temporarily stop from the operating section during the reproduction and output in the third step.

A non-transitory computer readable program recording medium storing, for a computer having a data reading section which reads data of an image, a calculating section, and an operation section, a program to cause the calculating section to execute:

• a first step reading, into the calculating section, respective data of a plurality of specified images being still images continued in a time base direction, and data of a motion image including a plurality of composite images generated by adding an image to the specified images based on addition rate data recorded in correspondence with the specified images and indicative of an addition rate of the image to the specified images, the image being different in the time base direction;
• a second step selectively executing a first reproduction mode which reproduces and outputs the specified images along time series and a second reproduction mode which reproduces and outputs the motion image in response to an input from the operation section;
• a third step generating first identification data indicative of a specified image being reproduced when receiving a time series reproduction stop instruction to stop reproduction of the specified images along the time series from the operation section in a state where the first reproduction mode is selected in the second step;
• a fourth step generating second identification data indicative of the specified image in correspondence with a composite image being displayed when receiving an instruction to stop reproduction of the motion image from the operation section in a state where the second reproduction mode is selected in the second step;
• and
• a fifth step erasing data of all the specified images except the specified images corresponding to one of the first identification data and the second identification data.

An image processing method using one or more computers, comprising:

• a first step reading, into the one or more computers, data of a plurality of still images generated by continuously imaging still images of a subject using an imaging apparatus;
• a second step, by the one or more computers, generating an interpolation image by interpolating change in position of the subject between two images of the plurality of still images;
• a third step, by the one or more computers, determining a specified image from among an object image group which includes the plurality of still images and the interpolation image, respective images in the object image group being continued in a time base direction;
• a fourth step, by the one or more computers, determining a first image to be added from images among the object image group before the specified image and with different positions of the subject in order to generate a composite image by adding the first image to be added before the specified image in a time base direction to the specified image, and, by the one or more computers, determining an addition rate of the first image to be added to the specified image;
• and
• a fifth step, in the one or more computers, recording data of the first image to be added and the addition rate in correspondence with data of the respective images in the object image group in association with the data of the respective images.
