Image projection apparatus, control method, and computer-readable storage medium

摘要

An image projection apparatus includes a light source in which a light emitting material emits light through an electric discharge between electrodes; an image forming unit that modulates an intensity of the light emitted from the light source to form an image; a cooling fan that cools the light source; an input unit that receives an input of an instruction signal for turning off a power source of the image projection apparatus; a voltage detector that detects a voltage value of the light source in lighting; a voltage value determining unit that determines whether the voltage value detected by the voltage detector is less than a preset threshold value when the input unit receives the instruction signal; and a cooling fan controller that performs an after-cooling operation of driving the cooling fan to cool the light source when the voltage value is less than the threshold value.

1. An image projection apparatus comprising:
a light source in which a light emitting material emits light through an electric discharge between electrodes; an image forming unit to modulate an intensity of the light emitted from the light source to form an image; a cooling fan to cool the light source; an input unit to receive an input of an instruction signal for turning off a power source of the image projection apparatus; a voltage detector to detect a voltage value of the light source in lighting; a voltage value determining unit to determine whether the voltage value detected by the voltage detector is less than a threshold value when the input unit receives the instruction signal; and a cooling fan controller to perform an operation of driving the cooling fan to cool the light source upon the voltage value determining unit determining that the voltage value is less than the threshold value.
