Abstract
A detection method and apparatus are provided. An energy detector detects energy values of pixels of different color regions of the to-be-detected image, and obtains a first parameter of the to-be-detected image through calculation based on the energy values, wherein the first parameter may indicate definition of the to-be-detected image. Projection quality of the projection device may be determined based on the first parameter.
Claims20
A detection method, comprising:
- obtaining a first energy value of a first region of a to-be-detected image and a second energy value of a second region of the to-be-detected image, wherein the first region is a single-pixel projection region of a first color, and the second region is a single-pixel projection region of a second color adjacent to the first region;
- and
- calculating a first parameter of the to-be-detected image based on the first energy value and the second energy value, wherein the first parameter indicates definition of the to-be-detected image.
A detection apparatus, configured to detect resolving power of a projection device configured to project a to-be-detected image, the detection apparatus comprising a receiving screen and an energy detector, wherein
- the to-be-detected image comprises at least one first region and at least one second region, the first region is a single-pixel projection region of a first color, and the second region is a single-pixel projection region of a second color adjacent to the first region;
- the receiving screen is configured to receive and display the to-be-detected image;
- and
- the energy detector is configured to obtain a first energy value of the first region and a second energy value of the second region of the to-be-detected image.
An electronic device, comprising a processor and a memory, wherein the memory is coupled to the processor, the memory is configured to store computer program code, the computer program code comprises computer instructions that, when executed, cause the processor to:
- obtain a first energy value of a first region of a to-be-detected image and a second energy value of a second region of the to-be-detected image, wherein the first region is a single-pixel projection region of a first color, and the second region is a single-pixel projection region of a second color adjacent to the first region;
- and
- calculate a first parameter of the to-be-detected image based on the first energy value and the second energy value, wherein the first parameter indicates definition of the to-be-detected image.
