    摘要: A sensor device includes an irradiation unit that includes a light source and irradiates an object with light, an optical detection unit disposed on an optical path of light emitted from the irradiation unit and reflected at the object, at least one object sensor that detects presence of the object, and a controller that controls the light source based on output from the object sensor.

    摘要: A focus point detecting apparatus comprises a HPF which extracts a high-frequency component from a picked-up image, and an ABS circuit which obtains an absolute value of the outputs of the HPF. A base clipping circuit removes a component equal to or less than a first threshold value from the output of the ABS circuit, and an another base clipping circuit removes a component equal to or less than a second threshold value which is larger than the first threshold value from the output of the ABS circuit. An integrator integrates the output of one of the base clipping circuits and an another integrator integrates the output of the other base clipping circuit. Finally, a computing circuit detects a focus point according to the integrated values in the two integrators. Therefore, focus point can be detected with higher precision.
