Patent ID: 11941789
Assignee: GOPRO, INC.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. An image capture apparatus, comprising:
an image sensor;
a processor; and
a memory including instructions executable by the processor to:
capture an image using the image sensor;
divide the image into a plurality of blocks including a given block;
separate low frequency information of the given block and high frequency information of the given block;
perform multiple tone control against the low frequency information of the given block to produce processed low frequency information;
perform local tone mapping against the high frequency information of the given block using an edge preservation filter to produce processed high frequency information;
produce a processed image based on the processed low frequency information and based on the processed high frequency information, the processed image corresponding to the image captured using the image sensor; and
output the processed image for storage or display
wherein a resolution of the multiple tone control is increased based on a size of the edge preservation filter, and
wherein increasing the resolution of the multiple tone control compensates for an effect on medium frequency information of the image by the local tone mapping.
