An image processing device is capable of suppressing the influence of the direction in which the image is projected on the projection surface to thereby improve the accuracy of the focus adjustment. Those of the resistance layers which are provided in areas existing between the gaps Gy include first resistance layer segments adjacent to the phosphor film segments, and second resistance layer segments adjacent to the first resistance layer segments. When the holder part is moved downward, articles are received in the receiving space of the housing. The pseudo recording signal crosstalk signal generated by the adaptive filter is supplied to the subtraction circuit. A compelling feature of this approach is that it only requires a single digital image depicting a human face as source data.
