PROBLEM TO BE SOLVED: To provide a solid-state imaging apparatus which can acquire an illuminance value in short time by using a structure for imaging a subject image and can suppress fluctuation of time required for acquiring the illuminance value.SOLUTION: A solid-state imaging apparatus 5 includes an integration section 14, an illuminance value calculating section 15 and an illuminance value output section 16. The integration section 14 integrates a luminance value detected for each pixel in an imaging section 11. The illuminance value calculating section 15 calculates an illuminance value according to an integration result in the integration section 14. The illuminance value output section 16 outputs the illuminance value calculated in the illuminance value calculating section 15. The imaging section 11 can preform imaging corresponding to two or more illuminance measurement conditions. The illuminance measurement condition is previously set by varying at least one of electronic shutter time and an analog gain. The illuminance value output section 16 outputs the illuminance value calculated in the illuminance value calculating section 15 with the subject image obtained by applying one of the two or more illuminance measurement conditions as an object. |
