A color filter array pattern for use in a solid-state imager comprising red sensitive elements located at every other array position, with alternating blue sensitive and green sensitive elements located at the remaining array positions, is disclosed. Since red color is sampled most frenquently, the color filter may be part of an in vivo camera system for imaging internal human body organs and tissues.

Color filter imaging array and method of formation

A digital electronic still camera has an image pickup device to pick up an image to be photographed. The picked-up image data is compressed by a data compressing unit using the two-dimensional discrete cosine transformation (DCT), the optimum quantization table, and the Huffman coding. The optimum quantization table is selected by comparing a characteristic parameter of the image data with preliminarily obtained values for respective image kinds. The two-dimensional DCT provides transformation coefficients of image, which are linearly quantized with reference to the optimum quantization table. The quantized data is coded by the Huffman coding method to have a minimum length. The coded data is sent to a recording device, which records the coded data in a recording medium such as a memory card. Fuzzy control theory may be applied to determine whether the image attributes to a document, a portrait, or a landscape. The image attribute may also manually be set, for example, on an input device.

An image pickup system with an illuminating device capable of sequentially irradiating three kinds of color lights different from each other onto an object, an objective lens system forming images of the object with the color lights, a solid-state image sensor receiving the images of the object, a signal processing device producing individual color images of the object based on electric signals supplied from the solid-state image sensor, and a color dispersion device or a color separation device disposed in an optical path of light incident on the solid-state image sensor from the object. The color dispersion device includes the combination of variously shaped prisms and a diffraction grating, and the color separation device includes a structure compounded of dichroic mirrors, whereby the images with respective color lights are incident at positions shifted each other on the solid-state image sensor. The compound of signals indicative of individual color images makes it possible to bring about the object image with high resolution.

PURPOSE:To protect a conduit, connected to a canister, from heating by arranging an exhaust gas pipe approximately above a crank case at the front and the side of an engine, and installing a canister for suction of vaporized fuel in front of the crank case at the other side of the engine. CONSTITUTION:An engine 8 mounted on a motorcycle has a pair of exhaust ports 11 and 12 formed in front of a cylinder 10. In this case, after exhaust pipe gas pipes 13 and 14 extending from the exhaust ports 11 and 12, respectively, are suspended down to a position in the vicinity of the lower end of the cylinder 10, the directions thereof are changed to the rear along the right side of the cylinder 10. After the exhaust gas pipes are joined together at a collection part, they are extended rearwardly of a motorcycle. A canister 18 sucking vaporized fuel generated in the air intake system of the engine 8 or a fuel tank 17 and discharging it in intake air flowing in the cylinder during running of the engine is mounted in the front of a crank case cover 19 on the left side of a case 9 and in the rear of a guard pipe 7. This constitution interference of a conduit, connected to the canister 18, the exhaust gas pipe.

PURPOSE:To ensure a shutter function without using a mechanical mechanism, by discharging the electric charge stored at a photosensitive part to a transfer part and then transferring the electric charge stored newly at the photosensitive part to the transfer part when a prescribed period of time elapses after the first discharge of the electric charge. CONSTITUTION:When a shutter button 9 is pushed, a pulse 15 delivered from a rise detector 13 in the timing of the front edge of a pulse signal 12 delivered from a monostable-multivibrator 11 is applied to a gate pulse generator 17 in the form of a gate pulse GP. Therefore a transfer gate of a solid state image pickup element 3 is opened, and the electric charge so far stored at a photosensitive part is discharged via a transfer part. From this time point the storage of the electric charge corresponding to an object image 1 is started. Then the rear edge of the signal 12 is detected by a fall detector 14 when the time T corresponding to a shutter speed elapses, and an output pulse 16 is applied to the transfer gate as a pulse GP. Therefore the electric charge corresponding to the image 1 and stored at the photosensitive part for the time T is delivered via the transfer part in the form of a picture signal and recorded to a frame memory 6.
