Image processing and presentation

An image acquisition apparatus comprising:

• a first image sensor configured to capture a first image, the first image sensor being a visible-light image sensor and the first image being a visible-light image;
• a second image sensor configured to capture a second image, the first image and the second image including same contents, the second image sensor being an infrared image sensor and the second image being an infrared image;
• a processor coupled to the first image sensor and the second image sensor;
• and
• a memory coupled to the processor and storing instructions that, when executed by the processor, cause the processor to:
• obtain the first image and the second image;
• size-process the first image according to at least one of a target resolution, an aspect ratio of the first image, or an aspect ratio of the second image to generate a size-processed first image having the target resolution, and the resolution of the second image being less than an initial resolution of the first image before being size-processed;
• generate a presenting image at least by combining the size-processed first image and the second image, the presenting image having a preset resolution that is not less than a sum of the target resolution and a resolution of the second image, the preset resolution being a resolution required by a display device, and the size-processed first image and the second image being arranged in the presenting image without partially blocking each other;
• and
• encode the presenting image in a code stream and transmit the encoded presenting image to the display device.

A terminal device comprising:

• a processor;
• and
• a memory coupled to the processor and storing instructions that, when executed by the processor, cause the processor to:
• obtain a first image captured by a first image sensor and a second image captured by a second image sensor, the first image and the second image including same contents, one of the first image and the second image being a visible-light image, and another one of the first image and the second image being an infrared image;
• size-process the first image according to at least one of a target resolution, an aspect ratio of the first image, or an aspect ratio of the second image to generate a size-processed first image having the target resolution, wherein size-processing the first image includes:
• cropping the first image according to the aspect ratio of the second image to obtain a cropped first image;
• and
• size-processing the cropped first image according to the target resolution;
• generate a presenting image at least by combining the size-processed first image and the second image, the presenting image having a preset resolution that is not less than a sum of the target resolution and a resolution of the second image, the preset resolution being a resolution required by a display device, and the size-processed first image and the second image being arranged in the presenting image without partially blocking each other;
• and
• encode the presenting image in a code stream and transmit the encoded presenting image to the display device.
