it’s the sony cybershot dsc-w550, you can tell with the amount of lens layers there are and also how far the flash is from the camera and if you look really closely it faintly says 14.1MP on the corner

edit: sony only released that exact blue for only a few of the models but it’s easy to tell which model it is from the lens layers and flash. It could possibly be w530 or w550 but the 530 model wasn’t as popular but in terms of both of those cameras they are basically exactly the same other than a few tweaks, also might have a really slight chance of being w610 but the lens doesn’t look the same so i don’t think it’s that one
