Abstract:
PROBLEM TO BE SOLVED: To easily obtain, through imaging or the like, an image similar to various image effects, in particular, to the image effect such as long-time exposure or the first-curtain synchronization/the second-curtain synchronization/multi-flash utilizing the long-time exposure. SOLUTION: An image processing apparatus generates and displays composite image data of a long-time exposure effect or the like obtained by compositing images of frames obtained sequentially for a predetermined frame term in capturing a subject image or playing back a motion image (F105-S107). By continuing this operation, an image of the long-time exposure effect is displayed in a motion image manner as a monitor indication in imaging or playing-back. A user is enabled to aim at a shutter chance while watching this display. In accordance with a recording operation of shutter operation or the like of the user, by recording on a recording medium the composite image data in that timing, an image of a desired special effect in a scene desired by the user is obtained.

PROBLEM TO BE SOLVED: To enable a general user to easily actualize image effects similar to image effects of long-time exposure, leading-curtain synchronization, trailing-curtain synchronization, multiple light emission, etc., and to obtain smooth picture quality. SOLUTION: During imaging for obtaining image data of a plurality of frames, having temporal continuity, to be used for combination processing for obtaining a long-time exposure effect, a frame rate is varied according to variation in subject luminance to adjust luminance of an imaged image. Consequently, a series of image data of a plurality of frames having temporal continuity is obtained to keep subject luminance of each image constant and to minimize absence of information as a subject video. Such a series of image data are combined to easily obtain a special effect image smoothly representing movement of a subject as the effects of long-time exposure, leading-curtain synchronization, trailing-curtain synchronization, multiple light emission, etc. COPYRIGHT: (C)2010,JPO&INPIT
