Information processing device and information processing method

An information processing method, comprising:

• in an information processing device that includes a camera and a central processing unit (CPU):
• receiving, by an image sensor, external light, wherein the camera includes the image sensor;
• acquiring, by the camera, a first image based on the received external light;
• emitting, by a light emitting diode (LED), infrared light, wherein the camera includes the LED;
• acquiring, by the camera, a second image based on the emitted infrared light;
• determining, by the CPU, an illuminance of the external light is one of:
• equal to or greater than a threshold, or
• less than the threshold;
• generating, by the CPU, a third image from the second image;
• performing a measurement process, by the CPU, based on the generated third image and the determination that the illuminance of the external light is less than the threshold, to measure a distance to a subject;
• generating, by the CPU, a fourth image from the first image;
• and
• performing, by the CPU, a subject recognition process based on the generated fourth image and the determination that the illuminance of the external light is equal to or greater than the threshold.

A non-transitory computer-readable medium having stored thereon, computer-executable instructions which, when executed by an information processing device, cause the information processing device to execute operations, the operations comprising:

• receiving, by an image sensor, external light, wherein
• the information processing device includes a camera and a central processing unit (CPU), and
• the camera includes the image sensor and a light emitting diode (LED);
• acquiring, by the camera, a first image based on the received external light;
• emitting, by the LED, infrared light;
• acquiring, by the camera, a second image based on the emitted infrared light;
• determining, by the CPU, an illuminance of the external light is one of:
• equal to or greater than a threshold, or
• less than the threshold;
• generating, by the CPU, a third image from the second image;
• performing a measurement process, by the CPU, based on the generated third image and the determination that the illuminance of the external light is less than the threshold, to measure a distance to a subject;
• generating, by the CPU, a fourth image from the first image;
• and
• performing, by the CPU, a subject recognition process based on the generated fourth image and the determination that the illuminance of the external light is equal to or greater than the threshold.
