Problems solved by technology

However, in the case of using the second application method, only the original image is displayed at the time of shooting, and the user cannot recognize what kind of image can be made afterwards
Although a display screen for confirming the appearance of the image to be acquired is provided, it is not possible to confirm the appearance of the final target image at the time of shooting, so it is inconvenient and not preferable

no. 1 approach

[0041] The first embodiment of the present invention will be described. figure 1 It is an overall schematic block diagram of the imaging device 1 according to the first embodiment. The imaging device 1 is a digital still camera that can capture and record still images, or a digital video camera that can capture and record still images and moving images. The imaging device 1 may also be mounted on a mobile terminal such as a mobile phone.

[0042] In the imaging device 1, an imaging unit 11, AFE 12, image processing unit 13, microphone unit 14, audio signal processing unit 15, display unit 16, speaker unit 17, operation unit 18, recording medium 19, and main control unit 20 are provided. A shutter button 21 is provided in the operation unit 18.

[0043] Such as figure 2 As shown in (a), imaging units 11A and 11B are provided in the imaging unit 11. The internal structure of the imaging unit 11A is the same as that of the imaging unit 11B. Therefore, refer to figure 2 (b) The in...

[0111] The second embodiment of the present invention will be described below. The second embodiment is an embodiment based on the first embodiment. Regarding matters not specifically described in the second embodiment, the description of the first embodiment can be applied to the second embodiment.

[0112] In the second embodiment, as an example, it is assumed that the subject groups housed in the respective shooting ranges of the imaging units 11A and 11B include subjects 421 to 423. The subjects 421 to 423 are people respectively, such as Picture 20 As shown, the subject distances of subjects 421 to 423 are respectively used as d 421 , D 422 And d 423 To represent. Here, 0421 422 423 , To simplify the description, the subject distance d 421 , D 422 And d 423 Set to unchanged. Figure 21 The image 440 in (a) is an example of a reference original image obtained by photographing the subjects 421 to 423.

[0113] After obtaining the reference original image 440, Image 6 The main...

no. 3 approach

[0133] The third embodiment of the present invention will be described below. In the third embodiment, a modification technique of the above-mentioned technique applicable to the first or second embodiment will be described.

[0134] Although the method of generating the target image using the output signals of the two imaging units 11A and 11B has been described, the imaging unit 11B may be removed from the imaging section 11 and only the output signal of the imaging unit 11A may be used to generate the target image.

[0135] For example, the imaging unit 11A may be formed in advance so that the first RAW data contains information indicating the distance of the subject, and the distance image and the all-in-focus image may be constructed based on the first RAW data. In order to realize this technology, for example, a method called "Light Field Photography" (for example, the method described in International Publication No. 06 / 039486 or JP 2009-224982, hereinafter referred to as L...

Abstract

An image pickup apparatus includes an operating portion that receives an operation to instruct to obtain a target input image based on an output signal of an image pickup portion, an aimed image generating portion that generates an aimed image in which a specific subject is focused by performing a first image processing on the target input image after the target input image is recorded, and a blurred image generating portion that generates a blurred image in which a non-specific subject is blurred by performing a second image processing on the output signal of the image pickup portion before the operation to instruct to obtain is performed. Before the target input image is obtained in accordance with the operation to instruct to obtain, the blurred image is displayed on the display portion.

Description

Technical field [0001] The invention relates to a digital still camera, a digital video camera and other imaging devices. Background technique [0002] The function of adjusting the focus state of the captured image through image processing is proposed, and there is a processing that performs this function is also called digital focus. As an application method of digital focus, consider the following first and second application methods. [0003] In the first application method, after the original image is taken according to the shutter operation, a target image focused on a specific subject is generated from the original image through digital focus immediately, without relying on the user's instruction, and only the target image is recorded in In the recording medium. [0004] In the second application method, the original image captured by the shutter operation is not digitally focused, but the original image is temporarily recorded in the recording medium. After that, in the re...
