Abstract:
1. An image taking apparatus that images a subject on an imaging device to create an image representative of the subject, the image taking apparatus comprising: through image creating means that repeatedly creates images before photography; movement vector computing means that computes a movement vector for each of areas which are obtained by dividing each one of the images repeatedly created by the through image creating means into two or more areas, between the images; subject determining means that determines whether the subject is a still subject or a dynamic subject in accordance with the movement vectors computed by the movement vector computing means; image taking means in which when the subject determined by the subject determining means is a dynamic subject, a photography is performed in accordance with a first shooting mode to create a single photographic image through increasing a photography sensitivity, and when the subject determined by the subject determining means is a still subject, a photography is performed in accordance with a second shooting mode to create a series of two or more photographic images; image piling up means that, when the subject determined by the subject determining means is a still subject, creates a piled up image by adjusting each position of the two or more images obtained through performing the second shooting mode so that relative blurring is corrected between the two or more images, and then piling up the two or more images; subject brightness detection means that detects a brightness of the subject; and proper shutter time computing means that computes a proper shutter time to perform a photography with a proper exposure in accordance with the brightness of the subject detected by the subject brightness detection means, wherein when the proper shutter time computed by the proper shutter time computing means is shorter than a predetermined shutter time, the image taking means performs a photography in accordance with a third shooting mode to create a single photographic image under the proper shutter time without waiting for a determination result of the subject determining means, and when the proper shutter time computed by the proper shutter time computing means is longer than a predetermined shutter time, the image taking means performs, under the predetermined shutter time, a photography in accordance with the first shooting mode or the second shooting mode.
