Problems solved by technology
When the technology proposed in Patent Document 3 is used to solve this problem, the effect is small when the number of images taken to detect defective pixels is small, and the suddenness of the problem occurs when the number of images taken is large. Detection of pixel defects takes time
Furthermore, when the technology proposed in Patent Document 4 is used, when the light and dark edge portions of the subject are averaged, the level rises to cause false corrections.
Also, since only the same color is detected, small subjects such as stars may also be judged as defects
Therefore, in the prior art, in the case of sudden pixel defects, it is impossible to efficiently detect and remove the influence of pixel defects

Embodiment Construction
[0022] Next, preferred embodiments will be described using a camera to which the present invention is applied. The camera according to the preferred embodiment of the present invention is a digital camera. Roughly speaking, the image data based on the image data read out from the imaging element (image sensor 4) is displayed in a live view on the display unit, and the image data is displayed according to the operation of the release button. Image data subjected to image processing for recording is recorded in an external memory. In addition, when the relatively bright composite mode is set, a plurality of images are continuously captured, and the brightness of corresponding pixels (pixels at the same position) is compared, and if it is brighter, it is replaced with the image data of the pixel of interest , on the other hand, when it is not bright, image synthesis is performed without replacing with the image data of the pixel of interest (this is referred to as relatively brig...

An image composition apparatus according to the present invention comprising: an image acquiring section for acquiring first image data and second image data; a subtraction processing section for obtaining a difference value for each pixel for at least a part of the first image data and at least a part of the second image data; a filter processing section for applying filter processing based on a spatial frequency of an image to the difference value; and an image composition section for compositing at least a part of the first image data with at least a part of the second image data on the basis of an output of the filter processing.
Description
technical field [0001] The present invention relates to an image synthesis device, an image synthesis method, and a program for removing the influence of sudden pixel defects when synthesizing multiple pieces of image data. Background technique [0002] In recent years, an imaging device has been proposed that acquires a plurality of pieces of image data at predetermined time intervals, accumulates the plurality of pieces of image data and performs additive synthesis to monitor the captured image during bulb shooting (for example, refer to Japanese Laid-Open Patent No. 2005-117395 ( The following is Patent Document 1)), an image synthesis device that compares the luminance of each pixel of a plurality of pieces of image data, selects the luminance of a pixel with a higher luminance level, and performs image synthesis (for example, refer to Japanese Patent No. 4148586 (hereinafter Various image synthesizing devices for performing image synthesizing on a plurality of pieces of...
