config VIDEO_SW_ISP
bool "Video Software Image Signal Processor (ISP)"
imply PIXEL
help
Enable a software-based image processing pipeline, providing the essential components
of an Image Signal Processsor (ISP) exposing the essential features of the "pixel"
library as a native Video API.

config VIDEO_SW_ISP_STACK_SIZE
int "Stack size for the thread executing the pipelne"
default 1024
help
Stack size for the thread executing the pipeline. All of the processing elements are not
allocated on the stack but use global variables instead. The default value is therefore
planning only for the temporary variables.

config VIDEO_SW_ISP_THREAD_PRIORITY
int "Stack size for the thread executing the pipelne"
default 5
help
Priority for the thread executing the pipeline. The default value is an intermediate
starting point to be tuned arbitrarily to fit the application.

config VIDEO_SW_ISP_INPUT_WIDTH
int "Width of the input of the pipeline in pixels, used for buffer allocation purposees."
default 640
help
The default value is VGA width, a widespread default resolution supported broadly.

config VIDEO_SW_ISP_INPUT_HEIGHT
int "Height of the input of the pipeline in pixels, used for buffer allocation purposees."
default 480
help
The default value is VGA height, a widespread default resolution supported broadly.
