get_images ---- I already set page = first page such as pdf =pdf_file[0]. But it still get all images in whole pdf document.

A PDF creator has the liberty to define one /Resources object in the file, which refers to all the images and fonts and other stuff, which furtheron may be used by pages. Of course, a single page will only use a subset.
To build a page-specific subset, execute page.clean_contents() before doing page.get_images() etc.

page.clean_contents(), it works. Thanks for your kindly help.
