ABSTRACT:
A mobile terminal includes a lens/filter combination, a single-chip camera module and an integrated mobile terminal processor. The lens/filter combination responds to an image, for providing an optical image signal. The single-chip camera module responds to the optical image signal, and to an integrated mobile terminal processor control signal, for performing analog image processing functions (such as correlated double sampling (CDS) and automatic gain control (AGC)) before an analog-to-digital conversion (ADC), basic sensor driving and adjustment functions (such as pixel access, timing and basic automatic exposure control), and digital input/output (I/O) functions, and providing a sensor data output signal and a single-chip camera module control bus signal. The integrated mobile terminal processor responds to the sensor data output signal, and to the single-chip camera module control bus signal, for performing camera control and data conversion functions, for providing the integrated mobile terminal processor control signal.
