An unnamed Malaysian official told the Associated Press that the new satellite image was taken on Friday, and that one of the potential objects was estimated to be about the same size as one spotted by a Chinese satellite that appeared to be 22m (72ft) by 13m (43ft).
The possible debris was located about 930km (575 miles) north of where the objects reported by China and Australia over the past week, the official added.
A French foreign ministry statement said the objects were about 2,300km from Perth, but did not give a direction or say when the discovery was made.
It also clarified that the French authorities had passed on data in the form of "satellite-generated radar echoes" rather than images. Radar works by sending out radio waves or microwaves and listening for echoes that bounce back.
"France has decided to mobilise complementary satellite means to continue the search in the identified zone," the ministry statement added.
The Australian Maritime Safety Authority (Amsa) subsequently announced that that the search operation in the southern Indian Ocean had concluded for the day.
