no. 2 approach

[0144] In the first embodiment described above, in the fusion determination processing section 36-1, the calculated feature amount is compared with a determination threshold set in advance, and it is determined whether or not degradation of image quality has been caused in the fusion processing. Incidentally, in the case where the determination threshold is set in advance, the determination threshold thus set is not necessarily an optimum value for the imaging situation. Then, compared with the case of the first embodiment, in the second embodiment, by setting the determination threshold according to the imaging situation, determination as to whether or not degradation of image quality has been caused can be accurately performed.

no. 3 approach

[0162] In the first embodiment and the second embodiment described above, fusion determination as to whether or not deterioration in image quality has been caused in the fusion image is performed. In addition, demosaiced image data is selected for fusion image data generated by performing fusion processing based on the fusion determination result with the monochrome imaging image acquired in the imaging section 21-BW as a reference. , or image data associated with the color imaging image acquired in the imaging section 21-CR is generated by performing demosaic processing. Here, the fused image data indicates the imaged image of the viewpoint of the imaging section 21 -BW, and the demosaic image data indicates the imaged image of the viewpoint of the imaging section 21 -CR. Therefore, when the image data is switched according to the determination result when imaging a moving image, since the viewpoint is different before and after switching the image, the switching of the image...

Abstract

A fusion determination processing unit 36-1 determines whether or not image quality has deteriorated as a result of fusion processing, which generates a fusion image by fusing a black-and-white imageand a color image with one another using a fusion processing unit 35-fb with the black-and-white image as a reference, on the basis of characteristics calculated by using a black-and-white image obtained by imaging an imaging subject using an imaging unit 21-BW, and a color image obtained by imaging the imaging subject from a different viewpoint position using an imaging unit 21-CR. In addition, when determined that the image quality has not deteriorated due to the fusion processing, the fusion determination processing unit 36-1 selects fusion image data generated by the fusion processing unit35-fb, and when determined that the image quality has deteriorated due to the fusion processing, the fusion determination processing unit 36-1 generates an image selection signal for selecting demosaiced image data generated by a demosaicing processing unit 34, and outputs the signal to an image selection unit 39. Thus, it is possible to generate a high-quality image by using images obtained by aplurality of imaging units.

Description

technical field [0001] The present technology relates to an image processing device and an image processing method, each of which enables obtaining a high-sensitivity imaging image without deteriorating image quality by using imaging images acquired in a plurality of imaging sections. Background technique [0002] Hitherto, due to miniaturization / thinning, information processing terminals such as portable electronic devices (for example, smartphones) have greatly degraded in image quality of imaging sections compared with single-lens reflex camera devices and the like. To this end, for example, PTL 1 states that an imaged image generated by an imaging device attachable / detachable to / from an information processing terminal is supplied to the information processing terminal in a wireless communication manner. Furthermore, PTL 2 discloses that a plurality of imaging sections are provided, and a plurality of images are simultaneously generated, for example, an image of a first v...
