There is such a camera........but:

The Sony W1 and P100 fit your description.

But, you should be aware of some idiosyncrasies that keeps me from recommending the camera.

It is supposed to be a point-and-shoot camera with a lot of the features of a camera with manual overrides.

It does not live up to the point-and-shoot part.

To get consistantly good photos you must use some of the manual overrides.

If you want the details, you can visit a thread on a Sony Forum:

There is another camera that looks promising, but it depends upon what you call pocket size.

If 3.9 x 2.7 x 1.6 inches is pocket size in your opioion, take a look at the Kodak DX7440.
