Image processing device, image processing method, recording medium, and imaging device

An image processing device comprising:

• an image acquisition unit that acquires a moving image including plural viewpoint images continuously taken;
• a display unit that displays the moving image acquired by the image acquisition unit;
• a selection unit that selects a specific subject image from the moving image acquired by the image acquisition unit;
• a parallax acquisition unit that continuously acquires a parallax for the specific subject image selected by the selection unit from the plural viewpoint images of the moving image;
• a parallax history information generator that generates continuously parallax history information on the basis of the parallax acquired by the parallax acquisition unit, the parallax history information indicating variation with time of the parallax for the specific subject image and including a current parallax for the specific subject image;
• and
• a controller that displays on the display unit the plural viewpoint images of the moving image acquired by the image acquisition unit together with the parallax history information generated by the parallax history information generator,
• wherein in a case where an operation is performed concerning the parallax in the moving image, the parallax history information generator adds information indicating a timing of the operation concerning the parallax in the moving image to the parallax history information.

An image processing device comprising:

• a display unit that displays the moving image acquired by the image acquisition unit;
• a selection unit that selects a specific subject image from the moving image acquired by the image acquisition unit;
• a parallax acquisition unit that continuously acquires a parallax for the specific subject image selected by the selection unit from the plural viewpoint images of the moving image;
• a parallax history information generator that generates continuously parallax history information on the basis of the parallax acquired by the parallax acquisition unit, the parallax history information indicating variation with time of the parallax for the specific subject image and including a current parallax for the specific subject image;
• a controller that displays on the display unit the plural viewpoint images of the moving image acquired by the image acquisition unit together with the parallax history information generated by the parallax history information generator;
• an image processor that performs marking to give a mark for each specific subject image in the moving image;
• and
• a marking target instruction input unit that accepts an instruction input indicating the subject image of marking target of the subject images in the moving image,
• wherein the parallax history information generator generates the parallax history information indicating the variation of the parallax visually associated with the mark for each specific subject image, and when the subject image of the marking target is changed according to the instruction input from the marking target instruction input unit, the parallax history information generator generates the parallax history information indicating the temporal change of the parallax for the subject image of the marking target before change until a time of the change as well as indicating the temporal change of the parallax for the subject image of the marking target after the change from the time of the change.

An image processing method performed by use of an image acquisition unit that acquires a moving image including plural viewpoint images continuously taken and a display unit that displays the moving image acquired by the image acquisition unit, the method comprising:

• a step of selecting a specific subject image from the moving image acquired by the image acquisition unit;
• a parallax acquisition step of continuously acquiring a parallax for the selected specific subject image from the plural viewpoint images of the moving image;
• a parallax history information generation step of continuously generating parallax history information on the basis of the parallax acquired in the parallax acquisition step, the parallax history information indicating variation with time of the parallax for the specific subject image and including a current parallax for the specific subject image;
• and
• a display step of displaying on the display unit the plural viewpoint images of the moving image acquired by the image acquisition unit together with the parallax history information generated in the parallax history information generation step and making the display cycle of displaying the parallax history longer than the cycle of acquiring the parallax by the parallax acquisition step.

A non-transitory computer-readable recording medium, when an instruction stored in the recording medium is read by a processor, the processor executes:

• a step of selecting a specific subject image from the moving image acquired by an image acquisition unit that acquires a moving image including plural viewpoint images continuously taken;
• a parallax acquisition step of continuously acquiring a parallax for the selected specific subject image from the plural viewpoint images of the moving image;
• a parallax history information generation step of continuously generating parallax history information on the basis of the parallax acquired in the parallax acquisition step, the parallax history information indicating variation with time of the parallax for the specific subject image and including a current parallax for the specific subject image;
• and
• a display step of displaying on a display unit the plural viewpoint images of the moving image acquired by the image acquisition unit together with the parallax history information generated in the parallax history information generation step and making the display cycle of displaying the parallax history longer than the cycle of acquiring the parallax by the parallax acquisition step.
