Image generating device using lighting control

An image generating device comprising:

• an irradiation unit configured to irradiate an object;
• a light receiving unit configured to receive light returning from the object;
• and
• a control unit configured to generate a light irradiation signal for controlling the irradiation unit and a light-receiving region driving signal for controlling the light receiving unit,
• wherein the irradiation unit includes a first irradiation unit for irradiating a first region of the object with light and a second irradiation unit for irradiating a second region of the object with light,
• wherein the light irradiation signal includes a first light irradiation signal for controlling the first irradiation unit and a second light irradiation signal for controlling the second irradiation unit,
• wherein the control unit is configured to:
• control the first light irradiation signal and the second light irradiation signal so as to prevent a light saturation phenomenon from occurring in the light receiving unit caused by the driving of the irradiation unit,
• sequentially perform a first operation of inputting the first light irradiation signal to the first irradiation unit and a second operation of inputting the second irradiation signal to the second irradiation unit,
• switch from the first operation to the second operation at a predetermined time point,
• control the light-receiving region driving signal so that receiving of the light intensity value begins at a first time point by the light receiving unit and the receiving of the light intensity value stops at a second time point, and
• generate an image based on the light received by the light receiving unit between the first time point and the second time point,
• wherein the first irradiation unit gradually decreases an intensity of the light irradiated to the object;
• and wherein the second irradiation unit gradually increases an intensity of the light irradiated to the object.
