Embodiment Construction

[0028] Next, an example of application to a digital camera will be described as an embodiment of the present invention. This digital camera has an imaging unit that converts a subject image into image data, and displays the subject image in a live view on a display unit arranged on the back of a main body based on the converted image data. The photographer determines the composition and shutter timing by observing the live view display. When the shutter release operation is performed, image data is recorded in the recording medium. When the reproduction mode is selected, the image data recorded on the recording medium can be reproduced and displayed on the display unit.

[0029] In addition, in general, the digital camera according to the first embodiment can control the FAT used for data recording, and can store in the temporary storage memory (SDRAM) in the camera in which position (such as which cluster) of the recording medium the saving data is recorded. . However, the...

Abstract

An imaging device of the present invention comprises an image data acquisition circuit for acquiring image data, a temporary storage for temporarily storing the image data, an image processing circuit for subjecting the image data that has been temporarily stored to image processing, a storage medium that can store at least some saved data of the image data that has been temporarily stored, a management information storage for storing management information for managing the save data, and a control circuit for, when the saved data is stored in the storage medium, carrying out management of the saved data using the management information.

Description

technical field [0001] The present invention relates to an imaging device, an imaging method, and a data recording device that temporarily store a plurality of image data when image processing is performed, and perform image processing using the temporarily stored image data. Background technique [0002] Some imaging devices such as digital cameras are equipped with an image processing function that captures multiple images to achieve image quality that cannot be expressed in one image. For example, in Japanese Laid-Open Patent Publication No. 2008-271240 (hereinafter referred to as Patent Document 1), an imaging device is proposed that uses a plurality of image data captured by moving the focus position to perform position alignment and image processing of the subject. Combining, thereby, all in-focus images and blur-controlled images can be generated. [0003] In addition, in Japanese Laid-Open Patent No. 2011-004353 (hereinafter referred to as Patent Document 2), the fo...
