Pulsating light is used to penetrate a user's finger placed an input surface (which can be a fiber optic surface) of a video camera to avoid the effects of bloodflow from a normal human pulse on the quality of the image which would otherwise change the contrast of the image. The use of pulsating light of shorter durations than a typical human pulse provides an accurate image of a portion of a finger for identification. A retractable cover blocks the fiber optic input surface during a non-working mode, and allows access for identification during a working mode. A light source having a plurality of light emitting diodes provides light that diaphans a portion of the finger. Several successive frames of image signals allow for biometric detection and verification of a human pulse to ensure the finger is not a counterfeit.

An image pickup apparatus includes a solid-state imaging device, an accumulating section, first and second imaging parameter setting sections, a calculating section, a flicker detecting section, and a switching section. The accumulating section calculates a projection output value of a predetermined line in a frame. The calculating section calculates inter-frame variations of the projection output values, and calculates a flicker index from the variations of a predetermined number of frames. The flicker detecting section detects the flicker from the index, and controls the switching section in response to the detection result of the flicker, so that the switching section selects either the setting signals from the first imaging parameter setting section or the setting signals from the second imaging parameter setting section. Thus, the charge storage time of the solid-state imaging device is set at either an integer multiple of 1/100 second or an integer multiple of 1/120 second in response to the frequency (50 Hz or 60 Hz) of a power supply of the fluorescent lighting. The image pickup apparatus can solve a problem of a conventional apparatus in that it is difficult for the conventional apparatus to suppress the flicker in regions where the frequency of the power supply differ from each other.

Terminal and method for transporting a still picture uses a moving picture terminal after extraction of a frame unit of still pictures, for example, from a moving picture. The extracted still picture frames can be encoded in a fixed quantizing value and stored before transmission, or the stored frame unit still pictures can be encoded in a fixed quantizing value using an overflow control technique or circuit. Further, the extracted still picture frame unit can be repeatedly sent using a varied quantizing value before transmission. Thus, the terminal and method for transporting a still picture permits transmission/reception of the still picture at a higher resolution than a moving picture regardless of time and place to enhance use of the moving picture terminal.

A second coat film is formed on a first coat film containing a conductive substance, the second coat film having an expansion coefficient almost the same as the expansion coefficient of the first coat film under a sintering condition. The first and second coat films are sintered at the same time. Thus, a conductive anti-reflection film with sufficiently low surface resistance, excellent water resistance and chemical resistance, and reduced reflected light can be obtained. When the conductive anti-reflection film is used, a cathode ray tube that is almost free from the AEF (Alternating Electric Field) and that displays a high quality picture for a long time can be obtained.

The current invention is a Photorefractive Flash Device and System. It is a device that can be clipped to any portable computing device to illuminate the pupil in a way, that allows a proper pupillary reflex. On the backside of the device is a photoreceptor, on the frontside—facing the persons eyes are LEDs, centered around an opening where the lens of the camera looks through. A smartphone-app triggers the flashlight of the camera. The photoreceptor of the device senses this flash and triggers the six LEDs to flash sequentially within 200 milliseconds. 200 milliseconds is the time, the pupil needs to react. By staying under this 200 milliseconds, it can achieve high-quality pictures of the pupillary reflection, before the pupil contracts.

When a video signal type detection section detects a video signal of the PAL method or the SECAM method (50Hz), it subjects the input image data to emphasis conversion processing with a smaller emphasis conversion degree than the NTSC method (60Hz), thereby improving the liquid crystal response speed, preventing generation of a video noise by excessive emphasis, and suppressing the image deterioration. As a result, it is possible to perform emphasis conversion for the input image data so as to compensate the optical response characteristic of the liquid crystal display panel and to prevent generation of a video noise by an excessive emphasis conversion for the image data of the PAL method or the SECAM method (50 Hz), thereby displaying a high-quality image.
