Abstract
An image processing apparatus that handles RAW images favorably performs display when shooting and display when reproducing. The apparatus images a subject and generates RAW images, and reduces the RAW images and generates reduced RAW images, The RAW images and reduced RAW images are recorded in a recording medium. When shooting, the reduced RAW images are subjected to developing processing for display, and when reproducing, the reduced raw images recorded in the recording medium are acquired and subjected to developing processing in accordance with instructions to reproduce, and each is used for display.
Claims14
An image processing apparatus comprising:
- an imaging unit configured to use an imaging sensor to acquire a RAW image representing a pre-development image from imaging signals of a subject image;
- a reduction unit configured to reduce the RAW image to generate a reduced RAW image;
- a first developing unit configured to acquire the reduced RAW image when shooting, and perform developing processing;
- a recording unit configured to record each data of the RAW image and the reduced RAW image in a recording medium;
- an instructing unit configured to instruct reproduction of the RAW image recorded in the recording medium;
- a second developing unit configured to acquire the reduced RAW image recorded in the recording medium and perform developing processing, in accordance with an instruction for reproduction;
- and
- a display processing unit configured to display a reproduction image subjected to developing processing by the second developing unit.

An image processing apparatus comprising:
- an imaging unit configured to use an imaging sensor to acquire a RAW image representing a pre-development image from imaging signals of a subject image;
- a reduction unit configured to reduce the RAW image to generate a reduced RAW image;
- a compression unit configured to compress each of the RAW image and the reduced RAW image;
- a recording unit configured to record each data of the compressed RAW image and the compressed reduced RAW image in a recording medium;
- a developing unit configured to read out the compressed. RAW image recorded in the recording medium in a predetermined state, perform developing processing in the background, and generate a developed image;
- and
- a reproducing unit configured to, at the time of reproducing of a certain RAW image being instructed, perform reproduction output of the developed image in a case where developing processing by the developing unit has ended, and reproduce the reduced RAW image reduced from the recording medium and perform developing processing by the developing unit when reproducing and perform reproduction output in a case where developing processing by the developing unit has not ended.
