FOCUS DETECTING DEVICE AND ELECTRONIC DEVICE

Abstract:

The present technology relates to a focus detecting device and an electronic device that can adjust the maximum value and the minimum value of sensitivity in phase detection pixels. The focus detecting device and an electronic device each include a microlens, a photoreceptor configured to receive light entering through the microlens, a light shield film provided between the microlens and the photoreceptor and configured to limit an amount of light on the photoreceptor, and a light shield wall provided vertical to the light shield film. The light shield wall or the light shield walls having a predetermined height are provided on any one or both of surfaces of the light shield film facing the photoreceptor and the microlens. The present technology can be applied to an imaging device configured to detect a focus by detection of phase difference.
