Provided are an imaging capturing device, an image capturing method, and a program that enable, without use of a costly optical low pass filter, simultaneous acquisition of a captured image having maximized precision and contrast and a captured image in which occurrence of moire and false color is eliminated, thereby flexibly accommodating a user's photography preference. A low pass selector image capturing controller (bracketing means) (110) performs image capture multiple times, including: low pass filter (LPF) ON image capture wherein an image signal from an image sensor (50) is acquired under an optical low pass filter effect by having the image sensor (moving member) (50) be driven for LPF operation by an image shake correction device (drive mechanism) (70); and LPF OFF image capture wherein an image signal from the image sensor (50) not under the optical low pass filter effect is acquired and the image sensor (moving member) (50) is not driven for LPF operation by the image shake correction device (drive mechanism) (70).
A photographing apparatus comprises an imaging sensor, a power supply controller, and a moving-picture generator. The imaging sensor continuously performs imaging operations in a predetermined interval. The power supply control unit controls power supply to the imaging sensor during a waiting period that is defined as a period from the end of one imaging operation of the imaging operations to the beginning of the next imaging operation of the imaging operations. The moving-picture generator generates a moving-picture file by incorporating a plurality of still pictures, obtained by the imaging operations, into a frame composing a moving picture.
The purpose of the present invention is to obtain an image capture device and control method therefor capable of obtaining a high quality captured image by implementing an optical low-pass filter effect that is uniform and even, and by stably removing moiré patterns and false colors, without being affected by the length of time during which the operation of the low-pass filter is unstable, which occurs when a moving member (image stabilization member) begins to be driven. An exposure initiation instruction means instructs the initiation of exposure of an image sensor. When the exposure initiation instruction means has instructed the initiation of exposure of the image sensor while the moving member is not driven by a drive mechanism, an exposure initiation control means causes the drive mechanism to begin driving the moving member, and then causes the exposure of the image sensor to be initiated when a predetermined time period, during which the operation of the low-pass filter is unstable, has elapsed after the initiation of the driving of the moving member.

An image capture mode setting means can set a still image capture mode and a specific image capture mode other than the still image capture mode. When the still image capture mode has been set by the image capture mode setting means, an LPF control means allows an optical low-pass filter effect to be obtained by driving, through a drive mechanism, a moving member in a plane perpendicular to the optical axis, whereas, when the specific image capture mode has been set by the image capture mode setting means, the LPF control means prohibits an optical low-pass filter effect from being obtained by driving, through the drive mechanism, the moving member in a plane perpendicular to the optical axis.

When an image-quality-prioritized continuous shooting mode has been set by a shooting mode setting means, an image-quality-prioritized continuous shooting control means causes a drive mechanism not to drive a moving member when image data is being read from the image sensor, causes the drive mechanism to resume driving the moving member each time the reading of image data from the image sensor has been completed, and causes the exposure of the image sensor to be resumed when a predetermined time period, during which the operation of a low-pass filter is unstable, has elapsed after the resumption of the driving of the moving mechanism.

When a digital camera (100) is operating in an auto-focus mode, a focus determination unit (112) determines on the basis of a photographed image whether or not a focusing lens (131) is focused on a subject, and causes the focusing lens (131) to be focused on the subject. The determination of whether or not the subject is in focus is referred to as focus determination, and a period in which the focus determination unit (112) is making a determination of focus is referred to as a focusing operation period. In the focusing operation period, an image correction unit (111) does not create a correction image. An LCD (122) receives a photographed image from a DSP (110) and displays the received image. At this time, the DSP (110) uses, in image processing, the computing power needed for correcting an aberration. This makes it possible to increase the number of photographed images processable per unit time and the resolution of the photographed images. In other words, a user can see a high-resolution and high-frame-rate image.
