low cost electronic sensor alternatives are there to video cameras?

photosensitive transistors?

essentially i would like to be able recognize the area of an object (hand, paper cutout) placed directly above an array of sensors, and display a low res image (silhouette) of the object on an lcd.

    Well, in a robot-building book they mentioned taking an old 2114 or similar RAM chip with the metallic top, carefully remove the lid and using the chip as a CCD...

    I have no idea how good it is, or where to get hold of the chips...

    You could also look for one of those cheap 'keychain' digital cameras and hack it apart to get the lens and CCD chip.
    (But where to find the data-sheet?)

    Those keychain cameras are nice and me a couple for some future projects....but what then you'd need is a way to convert it from it's digital (file-like) format in to a video signal for an LCD.· Assuming you'd have some sort of component input, you'd have the image to that....

    The CMUcam will track colour blobs for you.· but I don't know how you might output that signal to a display.

    There is this method from seattle robotics:
