Image processing apparatus and image processing method

Abstract

Object of the invention is to provide the whole picture becomes sharp focus the whole image. An imaging apparatus 1 is provided with a captured image acquisition unit 52, a combination sequence determination unit 53 and an image combination unit 54. The captured image acquisition unit 52 acquires the data of the plurality of captured images that have been imaged at the plurality of focus positions. The combination sequence determination unit 53 determines a sequence of the images imaged by an imaging unit 16, which sequence is different from both a progressive sequence of focus distances and a sequence of imaging, to be a sequence of combination of the data of the plurality of captured images acquired by the captured image acquisition unit 52. The image combination unit 54 combines the plurality of captured images imaged by the imaging unit 16, in the order determined by the combination sequence determination unit 53, creating data of an omnifocal image.

Description

technical field [0001] The present invention relates to an image processing device and an image processing method capable of providing an overall clear omnifocal image. Background technique [0002] Conventionally, an imaging device has used a super-depth lens (commonly referred to as an A special lens like "the bug's-eye lens". [0003] However, the insect eye lens has a very long overall length, so it is inconvenient to carry. [0004] Therefore, the following technology is disclosed in Japanese Patent Application Laid-Open No. 2007-282152: an imaging device equipped with a common lens can shoot a subject of the same composition at a plurality of focus positions almost simultaneously through one shutter operation, and As a result, data of a plurality of captured images obtained is combined to generate data of an all-in-focus image. [0005] However, in the prior art described above, the optical image of an object in the foreground or background that is not in focus is b...

Problems solved by technology

[0005] However, in the prior art described above, the optical image of an object in the foreground or background that is not in focus is blurred due to the in-focus position, so that the optical image diffuses, and the outline of the diffused optical image may sometimes appear blurred. False edge that doesn't exist

Therefore, the edge intensity as a whole will differ depending on the order of synthesis, making it difficult to obtain a sharp all-focus image
