Abstract

A digital camera includes: an imaging unit that obtains image data by capturing an image of a subject; a recording control unit that records the image data obtained by capturing the image of the subject into a plurality of recording media; a speed detection unit that detects access speeds at each of the plurality of recording media; and a selection unit that selects the recording media, into which image data are to be recorded by the recording control unit, based upon each of the access speeds having been detected, wherein: at least one of the plurality of recording media is an exchangeable recording medium.

Claims (22)

1. A digital camera, comprising:

a generating unit that generates image data by capturing an image of a subject;

a recording control unit that records the image data obtained by capturing the image of the subject into a first recording media with a first access speed and a second recording media with a second access speed;

a decision-making unit that decides which is faster between the first access speed and the second access speed; and

an estimation unit that estimates a data size of a first image data and a data size of a second image data to be generated by the generating unit in accordance with a single instruction of image capturing based upon image quality set by an user, wherein:

if the decision-making unit decides that the first access speed is faster than the second access speed, the recording control unit records the first image data into the first recording media and the second image data into the second recording media, the first image data and the second image data being generated by the generating unit in accordance with the single instruction of image capturing, and the data size of the second image data being smaller than the data size of the first image data; and

if the decision-making unit decides that the first access peed is faster than the second access speed, the recording unit records the first image data, of which the data size is estimated to be larger than the data size of the second image data, into the first recording media, and records the second image data, of which the data size is estimated to be smaller than the data size of the first image data, into the second recording media.

2. The digital camera according to claim 1 , wherein:

the generating unit further comprises a compression processing unit that generates image data executed under a compression process, wherein:

the first image data is generated without the compression process by the compression processing unit and the second image data is generated by engaging the compression unit in execution of the compression processing on the image data.

3. A digital camera, comprising:

an imaging unit that obtains image data by capturing an image of a subject;

a recording control unit that records the image data obtained by capturing the image of the subject into a plurality of recording media;

a speed detection unit that detects access speeds at each of the plurality of recording media; and

a selection unit that selects the recording media, into which image data are to be recorded by the recording control unit, based upon each of the access speeds having been detected, wherein:

at least one of the plurality of recording media is an exchangeable recording medium,

the digital camera further comprising:

a processing unit that generates a plurality of sets of image data by processing the image data having been obtained via the imaging unit; and

a size detection unit that detects data sizes of each of the plurality of sets of image data, wherein:

the selection unit individually selects the recording media into which the plurality of sets of image data are to be recorded in correspondence to the data sizes having been detected;

the plurality of recording media includes more than or equal to three recording media; and

when the recording control unit is to record image data into more than or equal to three recording media, the selection unit selects the recording media so that image data with a largest data size are recorded into a recording medium with a highest access speed.
