[0112] figure 1 Shows the appearance of the device of the image forming apparatus of the present technology. Note that, in the following description, the image forming apparatus, for example, be applied to the information processing terminal. figure 1 In (a) depicts a front-side information processing terminal 10, the display unit 53 and the operation portion 55 is disposed on the front side. figure 1 In (b) depicts the rear side of the information processing terminal 10, a plurality of image forming portions (e.g., two 21-BW, and the imaging unit 21-CR) is disposed on the rear side.

[0113] figure 2 Shows the configuration of the information processing terminal. The information processing terminal 10 includes a plurality of image forming portions (e.g., two image forming portion 21-H and 21-C), the image pr...

[0315] Now, an eighth embodiment of the image processing unit will be described. In the first to seventh embodiment, the signal generating color difference signal HUV is generated using the signal obtained by the captured image acquired by the imaging unit 21-H, and the color difference signal HUV includes less color pixels than the captured image acquired by the imaging unit 21-C. . That is, for the captured image acquired by the imaging unit 21-H, the low sampling rate is used for color pixels, and thus, for example, false colors (mixed noise) may occur in the chromatic aberration signal HUV. Therefore, in the eighth embodiment, even in the case of selecting a chromatic aberration signal HUV or synthesizing the color difference signal HUV, the deterioration of image quality performance caused by the low sampling rate of the color pixel is still prevented.

[0316] Figure 30 A configuration of an eighth embodiment of the image processing unit is shown. The image proces...

Abstract

The parallax detection unit 36a is based on the first imaging signal PS-H of the first viewpoint and the second imaging of the second viewpoint different from the first viewpoint having fewer white pixels and a larger proportion of color component pixels than the first imaging signal The signal PS‑C detects the parallax at the second viewpoint relative to the first viewpoint including white pixels and color component pixels. The parallax compensation unit 37 performs parallax compensation on the second viewpoint imaging signal based on the parallax detected by the parallax detection unit 36a to generate a parallax-compensated color difference signal for the first viewpoint. The fallback determination unit 38 and the signal selection unit 41 select the parallax-compensated second color difference signal or Color-difference signals from the first viewpoint to capture images with high sensitivity while suppressing image quality degradation.

Description

Technical field [0001] The present techniques relate to image processing apparatuses, image processing methods, and imaging devices, and uses capture images acquired by a plurality of imaging units to obtain high sensitivity capture images while suppressing deterioration of image quality performance. Background technique [0002] In the related art, in the portable electronic device, for example, an information processing terminal such as a smart phone, since the size and thickness of the information processing terminal are reduced, the imaging portion provides deterioration of image quality than a single lens reflective camera. Thus, for example, as described in Patent Document 1, providing a capture image generated by a radio communication to the information processing terminal in the information processing terminal and can be mounted from the information processing terminal and can be removed from the information processing terminal. Further, Patent Document 2 discloses a plur...
