Image capturing apparatus, image processing apparatus, and control method therefor

An image processing apparatus comprising:

• one or more processors;
• and
• a memory storing instructions which, when the instructions are executed by the one or more processors, cause the image processing apparatus to function as:
• an acquisition unit configured to acquire an image file including a first signal, an image signal, and defect data, the first signal and the image signal being signals obtained from an image sensing device, the defect data being data indicating a group of pixels for which when signals are read out from a plurality of photoelectric conversion elements in the image sensing device, the first signal is defective although the image signal is not defective;
• and
• a recording unit configured to record a Tiff image file acquired by the acquisition unit in a recording medium,
• wherein the Tiff image file comprises:
• IFD (Image File Directory) parts, each of which corresponds to one piece of image data;
• a thumbnail image part including thumbnail image data corresponding to the image signal;
• and
• an image part including image data corresponding to the image signal and the first signal,
• wherein the defect data is stored in an IFD part corresponding to the first signal.

An image processing apparatus comprising:

• one or more processors;
• and
• a memory storing instructions which, when the instructions are executed by the one or more processors, cause the image processing apparatus to function as:
• an acquisition unit configured to acquire an image file including a first signal, an image signal, and defect data, the first signal and the image signal being signals obtained from an image sensing device including a plurality of groups of pixels, each pixel of each group of pixels including a plurality of photoelectric conversion elements, the first signal being a signal from part of the plurality of photoelectric conversion elements, the image signal being a signal obtained by mixing signals from the plurality of photoelectric conversion elements, the defect data being data indicating a group of pixels for which when signals are read out from the plurality of photoelectric conversion elements, the first signal is defective although the image signal is not defective;
• and
• a recording unit configured to record a Tiff image file acquired by the acquisition unit in a recording medium,
• wherein the Tiff image file comprises:
• IFD (Image File Directory) parts, each of which corresponds to one piece of image data;
• a thumbnail image part including thumbnail image data corresponding to the image signal;
• and
• an image part including image data corresponding to the image signal and the first signal,
• wherein the defect data is stored in an IFD part corresponding to the first signal.

A non-transitory computer-readable medium storing a command that can be executed by a computer, wherein the command, upon being executed by the computer, causes the computer to function as an image processing apparatus comprising:

• an acquisition unit configured to acquire an image file including a first signal, an image signal, and defect data, the first signal and the image signal being signals obtained from an image sensing device, the defect data being data indicating a group of pixels for which when signals are read out from a plurality of photoelectric conversion elements in the image sensing device, the first signal is defective although the image signal is not defective;
• and
• a recording unit configured to record a Tiff image file acquired by the acquisition unit in a recording medium,
• wherein the Tiff image file comprises:
• IFD (Image File Directory) parts, each of which corresponds to one piece of image data;
• a thumbnail image part including thumbnail image data corresponding to the image signal;
• and
• an image part including image data corresponding to the image signal and the first signal,
• wherein the defect data is stored in an IFD part corresponding to the first signal.
