Assignee: TEXAS INSTRUMENTS INCORPORATED
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H | IPC H

Claim 7:
8. A system-on-a-chip (SoC) comprising:
an image signal processor (ISP) configured to generate statistics for automatic exposure (AE) control from an image captured by an image sensor coupled to the ISP;
a memory configured to store software instructions; and
at least one processor configured to execute the software instruction to implement automatic exposure (AE) control,
wherein to implement the AE control, the software instructions comprising software instructions that cause the at least one processor to:
obtain the generated statistics;
obtain values of one or more weights of a cost function, wherein the values of the one or more weights are predetermined using a learning process based on a plurality of images corresponding to different exposure values;
determine an exposure value EV using the cost function based on the generated statistics, wherein the cost function includes the one or more predetermined weights; and
determine AE settings for the image sensor based on the determined exposure value EV.
