[0029]

[0030] In this embodiment, an image processing device for correcting blur from one image will be described. Note that in this embodiment, camera shake is limited to translational shake. First, refer to figure 1 , to describe an example of the functional configuration of the correction unit 100 provided in the image processing apparatus according to the present embodiment. As described above, the correction unit 100 performs processing of correcting camera shake as translational shake from one image.

[0031] The imaging data (data of a captured image) is captured using an imaging device to input the captured imaging data to the input terminal 101 . In a subsequent stage, the image data is input to the deconvolution unit 106 . The dither vector recording unit 102 receives the dither vector information measured by another component of the image processing apparatus according to the embodiment via the input terminal 107 and records the received dither vector informa...

[0108] In this embodiment, an imaging system incorporating the image processing device described in the first embodiment will be explained. The following will refer to Figure 8 , to describe an example of the functional configuration of the imaging unit 1100 equipped in the imaging system according to this embodiment.

[0109] The light reflected by the imaging target enters the image sensor 1104 through the input terminal 1101 , the lens 1102 , and the shutter 1103 . The image sensor 1104 outputs an analog signal corresponding to incident light. The A / D converter 1105 converts an analog signal into a digital signal. The digital signal is input to the correction unit 100 via the output terminal 1109 as imaging data.

[0110] An exposure condition setting unit 1106 sets exposure conditions. Information representing the set exposure conditions is input to the shutter 1103 as exposure condition information, and is also input to the correction unit 100 via the output terminal...

[0114] In the second embodiment, optical anti-vibration is not taken into consideration. However, in the third embodiment, an imaging system combined with optical anti-vibration will be described. Below, will refer to Figure 9 , to describe an example of the functional configuration of the imaging unit 1200 equipped in the imaging system according to this embodiment. exist Figure 9 in, with Figure 8 The same reference numerals in the Figure 8 The description of the same parts will not be repeated here.

[0115] Image sensor movement detection unit 1201 detects movement of image sensor 1104 , and outputs the detection result as image sensor movement information to subtractor 1203 via output terminal 1202 . The subtractor 1203 subtracts the image sensor movement information detected by the image sensor movement detection unit 1201 from the shake vector information detected by the orientation detection unit 1107 . The subtraction result is input to the correction unit 1...

Abstract

The invention provides an image processing apparatus and an image processing method. An exposure condition when obtaining a sensed image is input. Shake information when obtaining the sensed image is input. A filter to be used to correct a blur of the sensed image is generated based on the exposure condition and a weight value including a non-integer obtained from the shake information.

Description

technical field [0001] The present invention relates to an image processing device and an image processing method. Background technique [0002] In recent years, improvements in resolution and zoom ratio of image pickup devices have brought about blurring of captured images caused by camera shake at the time of image capture, and have routinely led to widespread use of image pickup devices with camera shake correction functions. Such an imaging apparatus having a camera shake correction function generally uses an optical camera shake correction scheme using a sensor configured to detect a translation vector generated by camera shake and configured to control the relative positions of the lens and the image sensor to A drive device that counteracts camera shake to optically correct camera shake. [0003] On the other hand, methods of correcting camera shake through image processing have also been studied. In order to correct camera shake for a blurred image, there is known ...
