how does a camera sensor work?

i see that light goes through lenses, then through a colour filter, then the light sensor senses the light,

but how does it changes light intensity into digital binaries?

i;d like to know,

maybe cuz i don't know the right keywords?

i've searched for " how does light sensors work?"; and they just always skip how does it actually turn light into digital signals....

maybe like a solar panel connected to a transistor?

Light in the form of photons (in this case) strikes a matrix of dots on a camera chip. Depending on the inherent energy, carried by the photon, the sensor on the camera will produce varying voltages. This is because of the Photoelectric Effect.
