A substrate for fingerprint contact includes a plate, and the plate includes a first surface and a second surface. The first surface is an optical diffusing surface. The optical diffusing surface is used for being contacted by a finger, and features hazed particles. The second surface faces an optical imaging system. The optical diffusing surface of the plate helps to enhance light to be evenly emitted to the finger and weakens the unnecessary scattered light to the optical imaging system, so as to enhance the recognition rate of a fingerprint when the optical imaging system is used for intercept the light applied on a finger.

A vehicular lamp unit includes a projection lens disposed on an optical axis extending in a vehicular longitudinal direction; a light source disposed rearward of a rear side focal point of the projection lens; a reflector reflecting direct light from the light source forward towards the optical axis; a shade disposed between the projection lens and the light source such that the shade blocks a part of reflected light from the reflector and a part of the direct light from the light source to form a cut-off line of a light distribution pattern; a first reflective surface formed on a tip portion of the reflector such that the first reflective surface reflects a part of the direct light from the light source downward to the front of the shade; and a second reflective surface formed on the front of the shade and below the rear side focal point of the projection lens such that the second reflective surface reflects reflected light from the first reflective surface towards the projection lens. The first reflective surface is formed in a shape of an ellipsoidal reflective surface having a vertical cross-section that is generally ellipsoidal in shape, and the second reflective surface is formed in a generally flat shape having a linear vertical cross-section.

In one embodiment of the present invention, a display device includes: a display section in which a plurality of data signal lines and a plurality of scan signal lines are provided, the display section including (i) a first region including some of the plurality of scan signal lines to which a first scan signal is sequentially supplied and (ii) a second region including the others of the plurality of scan signal lines to which a second scan signal is sequentially supplied; and waveform adjusting sections for causing the first scan signal to have a waveform, during an active period, which is different from a waveform which the second scan signal has during an active period. This allows a display device, which drives a display section divided into a plurality of regions, to reduce a difference in luminance between the regions.

A combination of a latent-image pattern which forms a latent-image part and a background pattern that forms a background-image part is determined so that the latent-image part and background-image part have equal print densities. The determined latent-image pattern and background pattern, color information used to determine a color of the copy-forgery-inhibited pattern image, input image information as an image to be processed, copy-forgery-inhibited pattern basic information used to designate the latent-image part and background-image part, and camouflage region designation image information used to designate a camouflage region are input. A copy-forgery-inhibited pattern image is generated on the basis of the input information.

A pattern producing unit performs arithmetic on values of pixels corresponding to a pattern and a basic pattern read from a data storing unit with an AND operation unit, and thereby produces a pattern having substantially the same shade level as the pattern. The latent-image-containing image producing unit produces the latent-image-containing image by selectively combining the pattern and the produced pattern according to the values of respective pixels of mask image data read from the data storing unit for producing a latent image.

A notice management apparatus controls a notice instrument that provides a notice to an occupant of a vehicle. The notice instrument is mounted to the vehicle together with a vehicle control apparatus that achieves an assistance function assisting a lane change of the vehicle. The notice management apparatus includes a start time obtainer section and a notice adjuster section. The start time obtainer section obtains the information which indicates a steering start point of time at which the vehicle control apparatus starts a lane change of the vehicle. The notice adjuster section causes the notice instrument to provide continuously a notice indicating a decrease in a residual period of time up to the steering start point of time obtained by the start time obtainer section.

There is provided an active matrix display including pixels arrayed in a matrix form and each including a display element and a thin film transistor. In each of columns which the pixels form, the pixels are divided into a first pixel group in which the thin film transistors are arranged along a first straight line parallel with the column, and a second pixel group in which the thin film transistors are arranged along a second straight line parallel with the column and spaced apart from the first straight line.
