Abstract: PROBLEM TO BE SOLVED: To provide an image processor reduced in the sense of roughness when the number of gray levels is decreased. SOLUTION: A 1st color space value conversion means 10 obtains a 3-stimulus value from a pallet of an image forming device 3 and converts the 3-stimulus value into a 1st color space where the 3-stimulus value is arranged in a uniform color space. An adjusted 3-stimulus value generating means 20 obtains the 3-stimulus value from the input image to generate an adjusted 3-stimulus value obtained by adding errors from adjacent picture elements to the 3-stimulus value. A 2nd color space conversion means 30 converts the adjusted 3-stimulus value into a 2nd color space value where the adjusted 3-stimulus value is arranged in a uniform color space. A norm calculation means 40 obtains a difference between the 1st color space value and the 2nd color space value and calculates a norm. A minimum pallet selection means 50 selects a minimum pallet minimizing the norm. An output means 60 provides an output of a minimum pallet to the image forming device 3. An error spread means 70 obtains the 3-stimulus value between the input image and the minimum pallet uses the difference for an error, which is spread to adjacent picture elements.

Abstract: PURPOSE:To reduce stray light which reaches an image pickup element after being reflected on a lens barrel internal surface regardless of whether the incidence angle is large or small by using a light shield plate in a specific saw-tooth wave shape and setting a proper reflecting surface corresponding to the incidence angle of light incident on the lens barrel. CONSTITUTION:The light shield plate 19 is fitted to the internal surface bottom part of a main lens barrel 5 with an adhesive by engaging a claw piece 20 with a through hole 21, and plural reflecting surfaces 22 which are sectioned in a saw-tooth shape are formed on its top surface. On a subject side X, theta1 theta2 holds. Namely, when the same saw teeth with the subject side X are formed at this position, light B which has a large angle of incidence is reflected by the 1st surface 23 and travels toward the opposite side X' from the subject side and is further reflected by the 1st surface 23 after being reflected by a 2nd surface 24.
