no. 1 approach

[0056] The image processing device of the present embodiment is a device that performs shake correction of frame images captured by an imaging device. The image processing device is used, for example, for continuous shooting of a plurality of images and moving image shooting. The image processing device can be mounted on a mobile terminal with limited resources, such as a mobile phone, a smart phone, a digital camera, and a PDA (Personal Digital Assist: Personal Digital Assistant). However, the image processing device does not have to be mounted on these devices, and may be mounted on, for example, a normal computer system.

Abstract

One aspect of the present disclosure is an image processing device that performs shake correction of a frame image captured by a capturing device. This device has an acquisition unit, an image generation unit, and a cropping unit. The acquisition unit acquires a plurality of frame images. The image generation unit connects the first frame image among the plurality of frame images acquired by the acquisition unit with the second frame image which is any one frame image of several frames before and after the first frame image, and generates a ratio of the first frame image and the second frame image. Composite image with large size of two frame images. The cropping unit sets a cropped area in the synthesized image, and outputs the image in the cropped area as an output frame image.

Description

technical field [0001] The present disclosure relates to an image processing device, an image processing method, and a storage medium. Background technique [0002] Patent Document 1 describes an image processing device. This device determines an appropriate cutout area to be cut out from a captured frame image in order to remove the influence of camera shake or the like during moving image capture. This device detects motion data indicating the degree of deviation between a frame image and a reference frame image (for example, a frame image input last time), and moves or deforms a cut-out area according to the detected motion data, thereby performing correction to Makes the cutout area stationary relative to camera motion. However, in the device described in Patent Document 1, if the cropped area includes an area other than the frame area where the frame image and the reference frame image overlap, there may be an area that does not include pixel information in the blur-c...
