Embodiment Construction

[0023] Hereinafter, best modes for carrying out the present invention will be described in detail with reference to the accompanying drawings.

[0024] like figure 1 As shown, a digital camera 100 according to this embodiment includes an image sensor 101, a correction processing unit 102, an image memory 103, a smoothing processing unit 104, an interpolation processing unit 105, a recording medium 106, a display unit 107, and a control unit 108.

[0025] The image sensor 101 picks up an image of a subject, reads image data, performs optical correction such as brightness correction, black level correction, and the like on the image data, and supplies the processed image data to the correction processing unit 102 .

[0026] The correction processing unit 102 performs signal processing such as edge enhancement, gamma correction, and color difference matrix conversion on image data supplied from the image sensor 101 , and supplies the processed image data to the image memory 103 ....

Abstract

Provided is an image processing device for changing resolution of image data in accordance with a distance from a reference point arbitrarily set in a screen of the image data. The image processing device includes: selection means for selecting from the image data, operation object pixels arranged in such a manner that the pixel interval is increased as the distance from the reference point is increased; smoothing process means for smoothing the operation object pixels selected by the selection means, by using the pixel values of the operation object pixels and the pixel values of the pixels positioned around the operation object pixels; and interpolation process means for interpolating the pixel values of the pixels not selected as the operation object pixels by the selection means from the pixel values of the operation object pixels positioned around them and smoothed by the smoothing process means.

Description

technical field [0001] The present invention relates to an image processing device, an image processing method, and a program that change the resolution of image data according to the distance from a reference point arbitrarily set within a screen. [0002] This application claims priority based on Japanese Patent Application No. 2006-244755 filed in Japan on September 8, 2006, and this application is hereby incorporated by reference. Background technique [0003] Hitherto, in personal computers, various image effects have been added to image data picked up by a digital camera by executing image processing software and processing the image data. [0004] For example, when a soft focus effect is added to a picked-up image, a conventional video camera using a silver salt film requires an attachment of a filter such as a soft filter, a low-contrast filter, etc. when capturing an image. In contrast, with image processing software executable in a personal computer, image process...
