Abstract:
1. An on-screen device for an image of interest in a portable electronic device, comprising: an input device for inputting image-of-interest data representing an image of interest having a prescribed size equivalent to one frame of an image; a reading device for reading on-screen bitmap image data out of a storage medium that stores the on-screen bitmap image data, said on-screen bitmap image data representing an on-screen image, which has an amount of data less than that of reference bitmap image data representing the one frame of the image and which is superimposed on the image of interest represented by the image-of-interest data that has been input from said input device; an adjustment device for adjusting the amount of the on-screen bitmap image data in such a manner that the size of the on-screen image represented by the on-screen bitmap image data that has been read by said reading device will take on said prescribed size equivalent to one frame of an image; and a device for applying on-screen processing to the image-of-interest data and the adjusted on-screen bitmap image data in such a manner that the on-screen image, which is represented by the on-screen bitmap image data that has been adjusted by said adjustment device, will be superimposed on the image of interest represented by the image-of-interest data that has been input from said input device.
