no. 1 Embodiment approach 》

[0033] The first embodiment of the present invention will be described. figure 1 It is a schematic overall block diagram of the imaging device 1 according to the first embodiment of the present invention. The imaging device 1 is a digital video camera capable of photographing and recording still images and moving images. However, the imaging device 1 may be a digital still camera capable of capturing and recording only still images. In addition, the imaging device 1 may be a device mounted on a portable terminal such as a mobile phone.

[0034] The imaging device 1 includes a first processing unit including an imaging unit 11A and a signal processing unit 12A, a second processing unit including an imaging unit 11B and a signal processing unit 12B, and also includes parts referred to by reference numerals 13 to 20 . The first processing unit and the second processing unit can have the same functions as each other.

no. 2 Embodiment approach 》

[0076] A second embodiment of the present invention will be described. The second embodiment is an embodiment based on the first embodiment, and the matters described in the first embodiment can also be applied to the second embodiment as long as there is no contradiction. In the second embodiment, other image processing that can be performed by the imaging device 1 described above will be described.

[0077] Figure 9 It is a block diagram of parts particularly related to the image processing operation of the second embodiment. Figure 9 The focus state adjustment part 19 with figure 1 same.

[0078] The imaging units 11A and 11B form stereo cameras having parallax with each other. The captured images captured by the imaging units 11A and 11B, which are components of the stereo camera, are referred to as left-eye images and right-eye images, respectively. The left-eye image and the right-eye image are captured images of a common subject. exist Figure 10 In , images 31...

Abstract

An image sensing device includes: a first image sensing portion that shoots a first image; a second image sensing portion that successively shoots a plurality of second images with focus positions different from each other; a distance information generation portion that generates, based on the second images, distance information on subjects on the first image; and an image processing portion that performs image processing using the distance information on the first image.

Description

technical field [0001] The present invention relates to imaging devices such as digital still cameras and digital video cameras. Background technique [0002] A method of adjusting the focus state of a captured image by image processing to generate an image focused on an arbitrary subject after image capture has been proposed (for example, refer to Patent Document 1). One method of realizing this method is also proposed. Known as digital focus. [0003] In one of the image processing described above, the distance information indicating the subject distance of each subject is used, and based on the distance information, the part away from the main subject (subject that should be in focus) is faded. deal with. Usually, in the process of generating distance information based on images, multiple images captured from different viewpoints are required. When there is only one imaging unit (imaging system) installed in the imaging device, it is possible to generate distance infor...
