A shake correction control device includes a processor that selects mechanical correction of mechanically performing shake correction of a subject image or electronic correction of electronically performing the shake correction of the subject image. The processor performs a switching control from either of the mechanical correction or the electronic correction to the other of the mechanical correction or the electronic correction, and synchronizes shake correction operations of the mechanical correction and the electronic correction during the switching control, and changes an operation ratio of the mechanical correction and the electrical correction during the switching control.

A blur correction device includes a processor and a memory that is built into or coupled to the processor. The processor is configured to acquire an amount of blur correction used to correct blurring of an image obtained by imaging of an imaging element during exposure for one frame in the imaging element, and correct the blurring by performing image processing based on a most recently acquired amount of blur correction, on an unfinished image that is the image less than one frame that is being read from the imaging element. In a case in which a first reading period does not overlap with a second reading period, the processor corrects the blurring by performing the image processing based on the amount of blur correction acquired during exposure between the first reading period and the second reading period, on the unfinished image of the subsequent frame.

A shake correction control device includes a processor that acquires imaging information for selecting mechanical correction of mechanically performing shake correction of a subject image or electronic correction of electronically performing the shake correction of the subject image. The processor performs a switching control from either of the mechanical correction or the electronic correction to the other of the mechanical correction or the electronic correction, and synchronizes shake correction operations of the mechanical correction and the electronic correction during the switching control, and changes an operation ratio of the mechanical correction and the electrical correction in accordance with passage of time during the switching control.

A shake correction control device includes an acquisition unit that acquires imaging information for selecting mechanical correction of mechanically performing shake correction of a subject image or electronic correction of electronically performing the shake correction of the subject image, and a shake correction control unit. The shake correction control unit performs a first control for performing a switching control from the mechanical correction to the electronic correction by synchronizing shake correction operations of the mechanical correction and the electronic correction and a second control, different from the first control, for performing a switching control from the electronic correction to the mechanical correction based on the imaging information acquired by the acquisition unit.

A shake correction control device includes an acquisition unit and an operation control unit. The acquisition unit acquires, for each predetermined time, a related amount related to an operation recommendation condition under which an operation of a mechanical correction unit which corrects a shake of a subject image by mechanically moving at least one of a correction optical system or an imaging element is recommended. The operation control unit controls the operation of the mechanical correction unit and an operation of an electronic correction unit which corrects the shake by performing image processing on an image obtained by imaging performed by the imaging element. In a case where a state where the related amount acquired in the acquisition unit satisfies the operation recommendation condition does not continue for a setting period defined by a time series of a plurality of consecutive times, the operation control unit performs a control for operating only the electronic correction unit out of the mechanical correction unit and the electronic correction unit.

A shake correction control device includes an acquisition unit and an operation control unit. The acquisition unit acquires, for each predetermined time, a related amount related to each of a first operation recommendation condition under which an operation of a mechanical correction unit that corrects a shake of a subject image by mechanically moving at least one of a correction optical system or an imaging element is recommended, and a second operation recommendation condition under which an operation of an electronic correction unit that corrects the shake by performing image processing on an image obtained by imaging performed by the imaging element is recommended. The operation control unit performs a control for selectively operating the mechanical correction unit and the electronic correction unit at a subsequent time of a plurality of consecutive times depending on the first operation recommendation condition, the second operation recommendation condition, and a plurality of related amounts that are the related amounts acquired by the acquisition unit and correspond to the plurality of consecutive times.

When images from multiple viewpoints are required, respective imaging locations of the multiple viewpoints are specified and imaging operations themselves may be executed simply. When image data is to be imaged from plural viewpoints that are elements for generating a three-dimensional form of a specific subject, a user is appropriately guided. Messages prompting ranging directly in front of the specific subject, movement from the ranging position to an imaging start point, and movement from the imaging start point to an imaging end point are displayed in a message display region of an LCD monitor or the like. In addition, from analysis of a through-image, positions of a digital camera are automatically identified and automatic imaging is carried out on the basis of movements of feature points.

Multiple viewpoint imaging control device, multiple viewpoint imaging control method and computer readable medium

When the distance to an object is short and a release button is fully-pushed, one photographing unit acquires a left image. Translucence-processing is performed for the left image, and an optimum movement distance of a viewpoint between left and right images is calculated. The left image objected to the translucence-processing and the calculated optimum movement distance are superimposingly displayed on a live view image of a liquid crystal monitor, and the correlation coefficient of an object region and a background region are calculated for the live view image and the acquired left image. It is determined whether or not the correlation coefficient of the object region is equal to or greater than a first threshold value and whether or not the correlation coefficient of the background region is equal to or greater than a second threshold value, and if the threshold value determination is positive, one photographing unit acquires the right image.

There is provided a watermark information detecting method capable of detecting confidential information accurately from a document including confidential information. In this method, a filtering process is performed on the whole surface of an input image (S), and a position of signal is obtained by using a signal position searching template in order for the sum of filter output value to be maximum (S). Then a signal border is determined (S). Even when the image is expanded or contracted due to displacement of paper, etc., the signal position can be correctly detected and confidential information can be correctly detected from a document including confidential information.
