Problems solved by technology

The speckle-type time-of-flight device has a long detection distance, but the speckle-type time-of-flight device can only detect the area illuminated by the speckle, and what is obtained is the local part of the environmental object, that is, the resolution is low
The floodlight time-of-flight device has high resolution, but due to the limited light source power, the floodlight detection light power is small, which leads to the limited detection distance of the floodlight time-of-flight device

Abstract

The invention relates to the technical field of electronic equipment, in particular to an emission module, a time flight device and electronic equipment. The emission module comprises a first light source module, a second light source module and a driving module, and the first light source module comprises a plurality of first light-emitting units; the second light source module comprises a plurality of second light-emitting units, the projections of the second light-emitting units on the first light source module in the first direction do not coincide with those of the first light-emitting units, the light-emitting power of the first light-emitting units is larger than that of the second light-emitting units, and the first direction is perpendicular to the light-emitting surface of the first light source module; the driving module is connected with the first light source module and the second light source module, and the driving module is used for providing a first driving signal forthe first light-emitting units and providing a second driving signal for the second light-emitting units.

Description

technical field [0001] The present disclosure relates to the technical field of electronic equipment, and in particular, to a launch module, a time-of-flight device, and electronic equipment. Background technique [0002] Time-of-flight devices (TOF) are often used for depth detection, and commonly used time-of-flight devices include speckle-type time-of-flight devices and flood-type time-of-flight devices. The speckle-type time-of-flight device has a long detection distance, but the speckle-type time-of-flight device can only detect the area illuminated by the speckle, and what is obtained is the local part of the environmental object, that is, the resolution is low. The floodlight time-of-flight device has high resolution, but due to the limited light source power, the floodlight detection light power is small, which leads to the limited detection distance of the floodlight time-of-flight device. [0003] It should be noted that the information disclosed in the above back...
