Lighting apparatus, control method therefor and backlight apparatus

摘要

A lighting apparatus includes a plurality of light sources of which emissions of light are able to be controlled independently of one another, a control unit configured to control brightness of each light source, and a measurement unit configured to measure the brightness of each light source. In cases where the brightness of each light source is measured, the control unit carries out a first control which causes a measurement target light source to turn on and at the same time light sources other than the measurement target light source to turn off, and a second control which decreases the brightness of each of the light sources in a stepwise manner immediately before a turn-off period of time thereof, and which increases the brightness of each of the light sources in a stepwise manner immediately after the turn-off period of time.

1. A lighting apparatus comprising:
a plurality of light sources of which emissions of light are able to be controlled independently of one another; a control unit configured to control brightness of each of said light sources; and a measurement unit configured to measure the brightness of each of said light sources; wherein in cases where the brightness of each of said light sources is measured by said measurement unit, said control unit carries out a first control which causes a measurement target light source to turn on and at the same time light sources other than said measurement target light source to turn off, and a second control which decreases the brightness of each of the light sources in a stepwise manner immediately before a turn-off period of time thereof, and which increases the brightness of each of the light sources in a stepwise manner immediately after the turn-off period of time.
