Abstract
Cell phones and other portable devices are equipped with a variety of technologies by which existing functionality can be improved, and new functionality can be provided. Some relate to visual search capabilities, and determining appropriate actions responsive to different image inputs. Others relate to processing of image data. Still others concern metadata generation, processing, and representation. Yet others relate to coping with fixed focus limitations of cell phone cameras, e.g., in reading digital watermark data. Still others concern user interface improvements. A great number of other features and arrangements are also detailed.

17. A cell phone including a camera, a memory, a processor, a screen, and software in the memory for causing the processor to present a display indicating data comprising at least one of (1) a rotation from horizontal, (2) a rotation since an earlier time;
- and (3) a scale change since an earlier time, the processor determining said data by reference to information from the camera.
-
18. A cell phone including an image data sensor, a memory, a data processor, and a screen, the data processor defining two parallel processing chains:
-
a first processing chain for producing data to be rendered into perceptual form for use by human viewers, the first processing chain including at least one of a de-mosaic processor and a JPEG image compressor; and a second processing chain for producing data to be analyzed by one or more machine-implemented algorithms, the second processing chain including at least one of a Fourier transform processor, a discrete cosine transform processor, and an eigenface processor.

19. A mobile phone including a microphone and a radio transceiver, and additionally comprising an image sensor coupled to both a human visual system processing portion and a machine vision processing portion, wherein the image sensor is coupled to the machine vision processing portion without passing through the human visual system processing portion, and wherein the human visual system processing portion comprises a module selected from the group consisting of:
- a white balance correction module, a gamma correction module, an edge enhancement module, and a JPEG compression module.
