Abstract:
Disclosed in the present application are a dual-core focusing image sensor, a focusing control method thereof, and an imaging device. The dual-core focusing image sensor comprises a photosensitive unit array, a filter unit array provided on the photosensitive unit array, and a microlens array positioned on the filter unit array; the microlens array comprises first microlenses and second microlenses; the first microlenses are oval; one of the first microlenses covers one white filter unit; one white filter unit covers one focusing photosensitive unit; the area of the white filter unit is a half of that of the focusing photosensitive unit; the other half of the focusing photosensitive unit is covered with multiple second microlenses; one second microlens covers one dual-core focusing photosensitive pixel. The present application can increase the amount of light passing through focusing pixels, and provide a hardware basis for improving the focusing speed in a low light environment and ensuring the accuracy of image color reproduction.
