Time of flight sensor recorded with compensation parameters

A time-of-flight (TOF) sensor, comprising:

• a light source, arranged in the first accommodation space, and configured to illuminate light according to a light source driving signal;
• a light sensor, comprising a first pixel, arranged in the first accommodation space, and a second pixel, arranged in a second accommodation space different from the first accommodation space, and configured to generate output signals according to a sampling signal;
• a memory, configured to previously record a first reference phase-distance relationship associated with the first pixel at a reference temperature;
• and
• a processor, configured to, at an operating temperature,
• calculate an operation phase-distance relationship associated with the first pixel,
• calculate a temperature compensation and a temperature correction according to the first reference phase-distance relationship and the operation phase-distance relationship, and
• calibrate a current phase using the temperature compensation and the temperature correction.

A time-of-flight (TOF) sensor, comprising:

• an encapsulation, comprising a first accommodation space and a second accommodation space, wherein the first accommodation space is connected to a first opening and covered by a top cover surrounding the first opening, and the second accommodation space is connected to a second opening;
• a light source, arranged in the first accommodation space;
• a first pixel, arranged in the first accommodation space, and configured to receive reflected light projected by the light source to the top cover;
• and
• a second pixel, arranged in the second accommodation space, and configured to receive reflected light formed by emission light projected by the light source to penetrate the first opening of the first accommodation space, reflected by an external object, and then penetrating the second opening of the second accommodation space.
