Abstract
An information processing device and an information processing method capable of reducing an information processing amount of an application processor that recognizes a subject from an input image are provided. An information processing device according to the present disclosure includes an acquisition unit, a generation unit, and an output unit. From an imaging unit that captures an image and generates image data, the acquisition unit acquires the image data. The generation unit generates, from the image data acquired by the acquisition unit, metadata to assist an application processor that executes processing related to the image. The output unit outputs the metadata generated by the generation unit to the application processor.
Claims12
An information processing device, comprising:
- a central processing unit (CPU) configured to:
- acquire image data of an image captured by an imaging unit, wherein the image includes a subject;
- receive a request from an application processor that executes a first process related to the image, wherein the request is based on a type of the first process related to the image;
- generate metadata from the acquired image data based on the received request, wherein the metadata corresponds to the type of the first process related to the image;
- detect an edge of the subject in the image;
- detect, in the edge, a first plurality of pixels having an irregular color density;
- generate a watermark that includes a second plurality of pixels having a regular color density;
- assign the watermark to the image data by replacement of the first plurality of pixels having the irregular color density with the second plurality of pixels having the regular color density;
- and
- output the metadata and the image data having the watermark to the application processor.
An information processing method, comprising:
- acquiring image data of an image captured by an imaging unit, wherein the image includes a subject;
- receiving a request from an application processor that executes a process related to the image, wherein the request is based on a type of the process related to the image;
- generating metadata from the acquired image data based on the received request, wherein the metadata corresponds to the type of the process related to the image;
- detecting an edge of the subject in the image;
- detecting, in the edge, a first plurality of pixels having an irregular color density;
- generating a watermark that includes a second plurality of pixels having a regular color density;
- assigning the watermark to the image data by replacing the first plurality of pixels having the irregular color density with the second plurality of pixels having the regular color density;
- and
- outputting the metadata and the image data having the watermark to the application processor.
A non-transitory computer-readable medium having stored thereon, computer-executable instructions which, when executed by a computer, cause the computer to execute operations, the operations comprising:
- acquiring image data of an image captured by an imaging unit, wherein the image includes a subject;
- receiving a request from an application processor that executes a process related to the image, wherein the request is based on a type of the process related to the image;
- generating metadata from the acquired image data based on the received request, wherein the metadata corresponds to the type of the process related to the image;
- detecting an edge of the subject in the image;
- detecting, in the edge, a first plurality of pixels having an irregular color density;
- generating a watermark that includes a second plurality of pixels having a regular color density;
- assigning the watermark to the image data by replacing the first plurality of pixels having the irregular color density with the second plurality of pixels having the regular color density;
- and
- outputting the metadata and the image data having the watermark to the application processor.
