Image stabilizing device
View Patent ↗An image stabilizing device has an image restoration processor configured to perform image restoration process for stabilizing hand movement included in an input image by using an image restoration filter created based on hand movement information, and an edge emphasizing processor configured to perform edge emphasizing process for emphasizing an edge of the input image. The image stabilizing device has a stabilization mode determiner configured to determine an image stabilization mode for stabilizing the input image based on a size of the hand movement created by the hand movement information. The image stabilization mode includes a first mode for performing the image restoration process, a second mode for performing the edge emphasizing process, and a third mode for performing none of the image restoration process and the edge emphasizing process.
1. An image stabilizing device provided with an image restoration processor configured to perform an image restoration process for stabilizing hand movement deterioration included in an input image by using an image restoration filter based on hand movement information and provided with an edge emphasizing processor configured to perform an edge emphasizing process for emphasizing an edge of the input image, the image stabilizing device comprising:
a stabilization mode determiner configured to determine an image stabilization mode for stabilizing the input image based on a size of a hand movement created from the hand movement information, wherein the image stabilization mode includes a first mode for performing the image restoration process, a second mode for performing the edge emphasizing process, and a third mode for performing none of the image restoration process and the edge emphasizing process.
2. The image stabilizing device according to claim 1 , wherein the first mode is the image stabilization mode for performing the edge emphasizing process after the image restoration process is performed, and the second mode is the image stabilization mode for performing the edge emphasizing process without performing the image restoration process.
3. The image stabilizing device according to claim 1 , wherein the stabilization mode determiner determines the image stabilization mode based on trajectory information created from the hand movement information in addition to the size of the hand movement created from the hand movement information.
4. The image stabilizing device according to claim 1 , wherein the stabilization mode determiner controls strength for stabilizing the hand movement by using the image restoration filter based on whether or not a speed change of the hand movement created from the hand movement information is uniform speed.
5. The image stabilizing device according to claim 1 , further comprising: a ringing remover configured to perform a ringing removing process for removing ringing included in a stabilized image that is an image on which the hand movement is stabilized by the image restoration processor, wherein the first mode is the image stabilization mode for performing the ringing removing process after the image restoration process is performed, the third mode is the image stabilization mode for performing none of the image restoration process, the edge emphasizing process, and the ringing removing process, and the stabilization mode determiner controls strength for removing the ringing based on whether or not a speed change of the hand movement created from the hand movement information is uniform speed.
6. The image stabilizing device according to claim 1 , wherein the stabilization mode determiner determines the image stabilization mode by comparing the size of the hand movement with a predetermined threshold, and controls the predetermined threshold based on whether or not a speed change of the hand movement created from the hand movement information is uniform speed.
