    Abstract: Mobile phone accessory (1), to be associated with a smartphone, comprising a support and handling casing with an internal space (11a), an inner face (13a), an orifice (16) to be associated with an AOI target, located within a light incident spot (15), and a rear wall portion (14b), a lighting means (22) with an axis (22a), to produce the light illuminating the spot (15), a camera field of view (19) with an axis (19a), to make a reflection photo of the spot (15) and its content, a scattering plate (27), having a scattering opening (30) with a center (19aa) and a center (22aa), comprising a high-opacity portion and a low-opacity portion, which includes N color measurement targets (17), fixed on the face (13a) of the front wall portion (14a), sidely with the measurement orifice (16), through the scattering opening (30) is seen the spot (15), the scattering plate (27) has a varying degree of opacity, with a high-opacity degree in portion (25) or region (32a) on and around the center (22aa), a low-opacity degree in portion (26) or region (26b) at the opposite and near the scattering opening (30), and decreasing degrees of opacity from portion or region with high-opacity degree to portion or region with low-opacity degree, the scattering plate (27) making homogeneous the lighting as well the extension of the AOI target and the extension of the N color measurement targets (17).
