Image processing apparatus that synthesizes acquired images to generate successive images, control method therefor, and image pickup apparatus
First Claim
1. An image processing apparatus comprising:
- a first holding unit configured to hold a first set number of acquired images that are sequentially acquired;
a first synthesis unit configured to sequentially synthesize the first set number of newly held acquired images to generate first composite images;
a second holding unit configured to sequentially hold the first composite images;
a second synthesis unit configured to synthesize images from an image generated last to an image corresponding to a second set number among the first composite images held in said second holding unit to generate a second composite image; and
a generating unit configured to generate moving image data using the second composite images based on a moving image format,wherein said second holding unit is capable of further holding a generating condition for use in generating the first composite image, andwherein when said second holding unit holds the generation condition, said second synthesis unit generates the second composite image based on a synthesis condition determined with consideration given to the generating condition, the generating condition comprising a plurality of ISO sensitivities.

Abstract
An image processing apparatus that can reduce the area where acquired images are held and reduce the load in image synthesis when successive images are to be generated. Acquired images are sequentially acquired and held in an acquired image storage circuit. A first set number of acquired images among the acquired images are synthesized to generate first composite images. The first composite images are held in a grouped image storage circuit. Second composite images from an image generated last to an image corresponding to a second set number among the first composite images are synthesized to generate a second composite image. The acquired images used to generate the first composite images are sequentially deleted.

12. A control method for an image processing apparatus having a first holding unit configured to hold acquired images, a synthesis unit configured to synthesize a plurality of acquired images to generate first composite images, comprising:
-
a first holding step of storing, in the holding unit, a first set number of acquired images there are sequentially acquired; a first synthesis step in which the synthesis unit generates first composite images by sequentially synthesizing the first set number of newly held acquired images; a second holding step of sequentially holding the first composite images in the holding unit; a second synthesis step of synthesizing images from an image generated last to an image corresponding to a second set number among the first composite images held in said second holding step to generate a second composite image; and a generating step of generating moving image data using the second composite images based on a moving image format, wherein said second holding step is capable of further holding a generating condition for use in generating the first composite image, and wherein when said second holding step holds the generation condition, said second synthesis step generates the second composite image based on a synthesis condition determined with consideration given to the generating condition, the generating condition comprising a plurality of ISO sensitivities. - View Dependent Claims (13)
