ABSTRACT:
An image pickup device providing favorable images which effectively suppress the interference stripe noise originating in the interference stripes created on an image sensor surface of the image pickup device. The image pickup device includes an image sensor 3 and an overlying lid glass 2. By providing a prescribed inclination angle with respect to the relative position of the image sensor 3 and the lid glass 2 protecting it, the same number of interference stripes are provided with respect to each constitutional image-defining element within the image sensor 3, and prevention of interference stripe noise is achieved by leveling the average light intensity each constitutional image-defining element receives so that sensitizing of interference stripe noise does not occur at the specific elements.
