Image processing apparatus that performs processing concerning display of stereoscopic image, image processing method, and storage medium

An image processing method, comprising:

• receiving, from an image capturing apparatus on which a double optical system lens unit is mounted, image data including a first image area and a second image area, which are formed by being respectively obtained through an optical system for a right eye and an optical system for a left eye of the double optical system lens unit, and metadata associated with the image data;
• causing a display unit to display a stereoscopic image using the image data;
• determining whether or not to upgrade an application based on a file format of an image file indicated by the metadata;
• performing an upgrading process for upgrading the application by obtaining predetermined data from an external apparatus in accordance with a result of the determination;
• analyzing, after the upgrading process is performed on the application, the image data, comparing the first image area and the second image area, and thereby determining whether or not the first image area and the second image area are in a reversed state with respect to right and left in the image data;
• and
• performing, in a case where the result of the determination indicates that the first image area and the second image area are in a reversed state with respect to right and left in the image data, a process for replacing the first image area and the second image area with each other, right and left, in the image data,
• wherein the stereoscopic image is displayed on the display unit using image data which is subjected to the process for replacing the first image area and the second image area with each other, right and left, in the image data.

A non-transitory computer-readable storage medium storing a program for causing a computer to execute an image processing method,

• wherein the image processing method comprises:
• receiving, from an image capturing apparatus on which a double optical system lens unit is mounted, image data including a first image area and a second image area, which are formed by being respectively obtained through an optical system for a right eye and an optical system for a left eye of the double optical system lens unit, and metadata associated with the image data;
• causing a display unit to display a stereoscopic image using the image data;
• determining whether or not to upgrade an application based on a file format of an image file indicated by the metadata;
• performing an upgrading process for upgrading the application by obtaining predetermined data from an external apparatus in accordance with a result of the determination;
• analyzing, after the upgrading process is performed on the application, the image data, comparing the first image area and the second image area, and thereby determining whether or not the first image area and the second image area are in a reversed state with respect to right and left in the image data;
• and
• performing, in a case where the result of the determination indicates that the first image area and the second image area are in a reversed state with respect to right and left in the image data, a process for replacing the first image area and the second image area with each other, right and left, in the image data,
• wherein the stereoscopic image is displayed on the display unit using image data which is subjected to the process for replacing the first image area and the second image area with each other, right and left, in the image data.
