Abstract
An image signal processor accesses raw images from an image sensor. The image signal processor obtains adaptive acquisition control data for the raw images. The adaptive acquisition control data comprises at least one of a luminance value, a contrast value, a gain value, an exposure value, or a white balance value. The image signal processor obtains, in accordance with the adaptive acquisition control data, an indication of whether to use a star trails scene classification for the raw images. The image signal processor transmits, to buffers for storing data in accordance with the raw images, the indication of whether to use the star trails scene classification.
Claims20
A method, comprising:
- accessing, by an image signal processor, raw images from an image sensor;
- obtaining, by the image signal processor, adaptive acquisition control data for the raw images, the adaptive acquisition control data comprising at least one of a luminance value, a contrast value, a gain value, an exposure value, or a white balance value;
- obtaining, in accordance with the adaptive acquisition control data, an indication of whether to use a star trails scene classification for the raw images;
- and
- transmitting, by the image signal processor to buffers for storing data in accordance with the raw images, the indication of whether to use the star trails scene classification.
An apparatus, comprising:
- a storage unit;
- an image sensor;
- and
- an image signal processor to:
- access an electrical signal representing images from the image sensor;
- obtain adaptive acquisition control data for the images represented by the electrical signal, the adaptive acquisition control data comprising at least one of a luminance value, a contrast value, a gain value, an exposure value, or a white balance value;
- obtain, in accordance with the adaptive acquisition control data, an indication of whether to use a star trails scene classification for the images;
- and
- transmit, to buffers of the image signal processor for storing data in accordance with the images, the indication of whether to use the star trails scene classification.
A non-transitory machine-readable medium storing instructions that, when executed by an image signal processor, cause the image signal processor to:
- access raw images from an image sensor;
- obtain adaptive acquisition control data for the raw images;
- obtain, in accordance with the adaptive acquisition control data, an indication of whether to use a star trails scene classification or a daytime scene classification for the raw images;
- and
- transmit, to buffers for storing data in accordance with the raw images, the indication of whether to use the star trails scene classification or the daytime scene classification, the buffers receiving at least a portion of the data from a sensor readout component.
