摘要： PURPOSE: A photodetecting semiconductor apparatus and a mobile device are provided to perform measurement of luminance with high precision. CONSTITUTION: A photodetecting semiconductor apparatus comprises a voltage converting unit(21v), a shutter unit(21s), an amplifying unit(21a), an A/D converter(22), and an operation unit(26). The voltage converting unit accumulates photoreceptive current detected by a light receiving element(12) and changes the accumulated current into photoreceptive voltage. The shutter unit is connected between the light receiving element and the voltage converting unit. The amplifying unit is connected to the voltage converting unit and amplifies the photoreceptive voltage to be outputted. The A/D converter changes the photoreceptive voltage output from the amplifying unit into a digital value. The operation unit calculates the digital value changed by the A/D converter to a photoreceptive signal output from the light receiving element.
