An image data invoking system for an application, the system comprising: a capture mode library, set in a kernel layer, wherein the capture mode library is filled with an image with an image resolution size of full size; a preview mode library, set in the kernel layer, wherein the preview mode library is filled with an image with an image resolution size of binning size, and wherein the image resolution size of binning size is smaller than the image resolution size of full size; a first tag, set in a hardware abstraction layer, wherein the first tag is filled with an image with the image resolution size of binning size; a third tag (407, 408, 409), the third tag is set in the hardware abstraction layer, the third tag comprises three subtags (407, 408, 409), and the three subtags obtain the image with the image resolution size of binning size from the preview mode library; a second tag, set in an application framework layer, wherein the second tag obtains the image with the image resolution size of binning size from the first tag; a fourth tag (403, 404, 405), the fourth tag is set in the application framework layer, the fourth tag comprises three subtags (403, 404, 405), the three subtags of the fourth tag correspond to the three subtags of the third tag, and each subtag of the fourth tag obtains an image with the image resolution size of binning size from an corresponding subtag of the third tag to ensure that the image data invoking system passes the Compatibility Test Suite, CTS, test; and an application, set at an application layer, wherein the application obtains the image with the image resolution size of binning size from the second tag. a capture mode library, set in a kernel layer, wherein the capture mode library is filled with an image with an image resolution size of full size; a preview mode library, set in the kernel layer, wherein the preview mode library is filled with an image with an image resolution size of binning size, and wherein the image resolution size of binning size is smaller than the image resolution size of full size; a first tag, set in a hardware abstraction layer, wherein the first tag is filled with an image with the image resolution size of binning size; a third tag (407, 408, 409), the third tag is set in the hardware abstraction layer, the third tag comprises three subtags (407, 408, 409), and the three subtags obtain the image with the image resolution size of binning size from the preview mode library; a second tag, set in an application framework layer, wherein the second tag obtains the image with the image resolution size of binning size from the first tag; a fourth tag (403, 404, 405), the fourth tag is set in the application framework layer, the fourth tag comprises three subtags (403, 404, 405), the three subtags of the fourth tag correspond to the three subtags of the third tag, and each subtag of the fourth tag obtains an image with the image resolution size of binning size from an corresponding subtag of the third tag to ensure that the image data invoking system passes the Compatibility Test Suite, CTS, test; and an application, set at an application layer, wherein the application obtains the image with the image resolution size of binning size from the second tag.
