IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD
First Claim
1. An image processing device comprising:
- a processor; and
a memory which stores a plurality of instructions, which when executed by the processor, cause the processor to execute,acquiring an image including a first region of a user;
extracting a color feature quantity or an intensity gradient feature quantity from the image;
detecting the first region based on the color feature quantity or the intensity gradient feature quantity; and
selecting whether the detecting is detecting the first region using either the color feature quantity or the intensity gradient feature quantity, based on first information related to the speed of movement of the first region calculated from a comparison of the first regions in a plurality of images acquired at different times.
