Wide dynamic range electronic image recording and reproducing system

摘要

The electronic camera has an imaging device that images a subject with subject reflectance R (%) with a dynamic range wider than that at displaying or printing to acquire image data and a recording device that converts the image data acquired by the imaging device with a predetermined function and records the converted image data and the information on the function as digital values (digit). Therefore, a printed image with an automatically or manually corrected density can be obtained at the displaying or the printing.

主权项

1. An electronic camera, comprising:
an imaging device configured to image a subject to acquire a piece of image data, the imaging device configured to perform a normal imaging in which the imaging device images the subject in a first dynamic range, and to perform a wide dynamic range imaging without an image combining process in which the imaging device images the subject in a second dynamic range which is wider than the first dynamic range to acquire a piece of wide dynamic range image data by imaging the subject with an exposure value that is lower than an exposure value for normal imaging, wherein the first dynamic range corresponds to a reproducing dynamic range used for at least one of displaying and printing; and a recording device configured to record the acquired image data the recording device configured to record an information indicating that the piece of wide dynamic range image data which is directly acquired in the wide dynamic range imaging is imaged in the second dynamic range along with the piece of wide dynamic range image data.
