Problems solved by technology

Except for advanced models, many digital still cameras cannot change the photographic lens and have filters installed
For digital still cameras, which are characterized by small size, light weight, portability and ease of use, it is not appropriate to always equip a dedicated filter regardless of whether it is used or not.
Moreover, the objective lens of a digital still camera generally has a relatively small diameter.
Therefore, it is difficult to obtain a satisfactory soft-focus imaging effect by applying Vaseline or the like to the surface of the objective lens

[0026] figure 1 is a block diagram of the electrical configuration of the digital still camera according to the first embodiment of the present invention. This digital still camera has an AE (Automatic Exposure) function and an AF (Automatic Focus) function of contrast solutions. The digital still camera also has a soft focus mode as an operation mode when taking pictures.

[0027] The digital still camera of this embodiment has a fixed lens 1, a focusing lens 2, a CCD (Charge Coupled Device) 4 serving as an image pickup section that picks up an image of an object formed through an aperture 3, an aperture drive for changing the degree of opening of the aperture 3 Section 5, TG (Timing Generator) 6 and vertical driver (V driver) 7 for driving CCD 4, and unit circuit 8 including CDS (Correctional Double Sampling) circuit for holding an image pickup signal output from CCD 4, with AGC (Automatic Gain Controller) for amplifying image loss signals, and A / D converter (AD) for conve...

[0045] The second embodiment differs from the first embodiment in the program stored in the PROM 17 . In this embodiment, programs for making the MPU 10 function as a control section, an image pickup condition setting section, and an exposure control section are stored in the PROM 17 .

[0046] The following will refer to image 3 The flowchart of is describing the operation in the image pickup waiting state when the capture mode is selected in the digital still camera according to the present embodiment. In the following description it is assumed that the AE function of the digital still camera is active.

[0047] When the shutter button is pressed (YES in step SB1), it is determined in step SB2 whether the user has set the soft focus mode. If the soft focus mode is not set (NO in step SB2), an image (object image) is picked up by the CCD 4 (step SB3). The picked-up image is compressed and stored in the flash memory 13 (step SB9).

[0053] The third embodiment differs from the first embodiment in the program stored in the PROM 17 . In this embodiment, the MPU 10 has an AWB (Automatic White Balance) function of controlling a gain in an automatic gain controller (AGC) in the unit circuit 8 for each color in RGB. In addition, programs for making the MPU 10 function as an image pickup condition setting section and as a white balance control section together with the unit circuit 8 are stored in the PROM 17 .

[0054] The following will refer to Figure 4 The flowchart of is describing the operation in the image pickup waiting state when the capture mode is selected in the digital still camera according to the present embodiment. In the following description it is assumed that the AE function of the digital still camera is active.

[0055] When the shutter button is pressed (YES in step SC1), it is determined in step SC2 whether the user has set the soft focus mode. If the soft focus mode is not set (NO in ...

Abstract

When a shutter key is pressed, the first image (in-focus image) is picked up and temporarily stored. The focus position is changed to a near- or far-focus position. The second image (out-of-focus image) is picked up and synthesized with the first image. The synthesized image is a soft-focus image in which a background around the contour of a main object is blurred.

Description

[0001] Cross references to related patent applications [0002] This application is based on Japanese Patent Application No. 2001-185543 filed on June 19, 2001, and takes this application as a priority application document. The entire content of this application is hereby incorporated by reference. technical field [0003] The present invention relates to an image pickup device, an image pickup method, and a storage medium for recording a program of the pickup method suitable for a digital still camera. Background technique [0004] Traditionally, soft focus photography is one of the photographic techniques. For example, when shooting a portrait, use soft focus photography to make people stand out and things around them blur. For silver iodide photography, special filters and photographic lenses for soft focus photography are prepared. Anyone with a filter or lens can do soft focus photography. If there is no special optical filter or photographic lens, you can also appl...
