Problems solved by technology

However, sometimes when viewing a display of the entire scene to be captured, it can be difficult to tell when a small area of ​​interest relative to the size of the active display is out of focus
Consequently, users who take photos often only later discover, after having transferred the photos to a desktop or laptop computer with a larger display, that the photos are of too poor quality to share with friends or to print

Embodiment Construction

[0020] figure 1 is a block diagram of an embodiment of an image capture and processing system that includes an image processing system 130 having a region of interest locator 118 and a blur detector 122 . System 100 includes image capture device 101 coupled to image processing system 130 . The image processing system 130 is coupled to an image storage device 140 . Image processing system 130 is configured to receive image data 109 from image capture device 101 and to process received image data 109 by performing operations on the image data 109, including detecting a region of the image and determining the Whether the region is blurred. In general, system 100 may be implemented in an electronic device configured to perform real-time image processing using relatively limited processing resources.

[0021] In a particular embodiment, image capture device 101 is a camera (eg, a video camera or a still camera). In other embodiments, image capture device 101 may be a camera emb...

Abstract

A system and method to respond to detection of blurry regions of interest in an image are disclosed. One embodiment includes a region locator to locate one or more regions of interest in an image captured by a digital image capturing device. The embodiment also includes a blurry region detector for detecting whether a region of interest is blurry. A blurry region indicator indicates to a user when a blurry region has been detected. When a blurry region is detected, a display interface provides an enlarged image of the detected blurry region. Some embodiments provide recommendations on how to capture the scene again with improved results.

Description

technical field [0001] The present invention generally relates to blur detection in images. Background technique [0002] A camera or other image capture device, such as a camera phone, can provide autofocus capabilities and hand shake reduction features to assist users in taking good pictures. However, photos may sometimes be blurry, or areas of the photo that the user intended to be in focus may not be in focus. In some conventional cameras, an active display on the camera shows the image "as seen" by the camera to give the user a clear idea of ​​the quality of the pictures the user will be taking. However, sometimes when viewing a display of the entire scene to be captured, it can be difficult to tell when a small area of ​​interest relative to the size of the active display is out of focus. Therefore, after having transferred the photo to a desktop or laptop computer with a larger display, the user who took the photo often only later discovers that the photo is of too ...
