Abstract
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.
Claims10
An electronic camera, comprising:
- an imaging device configured to image a subject to acquire a piece of image data, wherein the imaging device is configured to perform a normal imaging in which the imaging device images the subject in a first dynamic range with a first exposure value, and to perform a wide dynamic range imaging in which the imaging device images the subject in a second dynamic range wider than the first dynamic range with a second exposure value lower than the first exposure value to directly acquire a piece of wide dynamic range image data without an image combining process, wherein the first dynamic range corresponds to a reproducing dynamic range used for displaying;
- and
- a recording device configured to record the acquired image data, wherein the recording device is configured to record information indicating that the piece of wide dynamic range image data is imaged in the second dynamic range along with the piece of wide dynamic range image data.
