Image processing device, image processing method, and image processing system

An image processing system, comprising:

• processing circuitry configured to:
• generate a first image having a first resolution;
• search the first image to determine whether a target object can be identified in the first image;
• specify, when it is determined that the target object can be identified in the first image, a region-of-interest in the first image, wherein the region-of-interest includes the identified target object;
• generate, when it is determined that the target object cannot be identified in the first image, a second image having a second resolution higher than the first resolution, wherein the second resolution is lower than a full resolution of an image sensor used to capture signals from which the first and second image are generated;
• search the second image to determine whether the target object can be identified in the second image;
• specify, when it is determined that the target object can be identified in the second image, a region-of-interest in the second image, wherein the region-of-interest in the second image includes the identified target object;
• and
• perform image processing only on the region-of-interest in the second image.

An image processing method, comprising:

• generating a first image having a first resolution;
• searching the first image to identify a target object in the first image;
• specifying, based on an identification of the target object, a region-of-interest in the first image, wherein the region-of-interest in the first image includes the identified target object;
• and
• activating one or more analog-to-digital converters (ADCs) corresponding to the region-of-interest specified in the first image to generate a second image corresponding to the region-of-interest, wherein the second image has a second resolution higher than the first resolution;
• wherein the second resolution is lower than a full resolution of an image sensor used to capture signals from which the first and second image are generated;
• and
• performing image processing only on the region-of-interest in the second image.
