DEFINITION

Classification: 348/222

Combined image signal generator and general image signal processing:

(under subclass 207) Subject matter including at least one image sensor or pickup device and in combination therewith related circuitry for correcting, adjusting, or otherwise altering the image signal output from the image sensor or pickup device.

(1) Note. The signal processing herein is limited to normal television signals, such as red, green and blue, or luminance and chrominance.

(2) Note. The image signal processing which depends upon structure of a sensor is not classified in this subclass, but is with the sensor, per se. For example, a single solid-state image sensor which converts the dot interlace output representing for example cyan, magenta, and yellow (i.e., not normal television signal) to red, green, and blue is found in subclass 280, solid-state color image sensor with filter based on three colors.

571+, for general image signal processing not with the image generator (i.e., not in the camera).
