Abstract: A camera system is provided. The system comprises a first camera fixed to a stage; a second camera which is disposed on a panhead fixed to the stage in a state in which a direction of an optical axis of the second camera is adjustable and which has a narrower field angle than the first camera; a storage unit in which a correlation between a positional coordinate in an image captured by the first camera and an angle of the panhead for directing the optical axis in a direction corresponding to a position of the positional coordinate is stored; and a control unit. The control unit controls the angle of the panhead based on the correlation such that the optical axis is directed to a position corresponding to a positional coordinate of a subject detected from an image captured by the first camera.

Abstract: An imaging system comprises a whole image read out unit for reading out a whole image in a first resolution from an imaging device, a partial image region selecting unit for selecting a region of a partial image in a part of the whole image which is read out, a partial image read out unit for reading out the partial image in the selected region in a second resolution from the imaging device, a characteristic region setting unit for setting a characteristic region, in which a characteristic object exists, within the partial image, a characteristic region image read out unit for reading out an image of the characteristic region, which is set, in a third resolution from the imaging device, and a resolution setting unit for setting such that the first resolution<the second resolution<the third resolution.

Abstract: According to the present invention, in the case where the amount of ink remaining in an ink tank is detected using light from a light emitting unit, whether or not the amount of remaining ink is smaller than a predetermined value can be accurately determined with a decrease in the life of the light emitting unit suppressed. Thus, the present invention determines a difference between output signals each output by the light receiving unit according to a corresponding one of at least two of a plurality of levels of light emissions from the light emitting unit. Based on the difference, whether or not the amount of remaining ink is smaller than the predetermined value is determined.

Abstract: A solid-state image pickup apparatus includes rows and columns of pixels, each column or each set of a plurality of columns being provided with an analog-to-digital converter. When an operation for holding analog electric signals performed by the analog-to-digital converters is performed simultaneously with an operation for outputting data from memories holding digital signals that are output from the analog-to-digital converters, “streaky noise” artifacts appear on an image obtained by such operations. To avoid this, the operation for holding the analog electric signals and the operation for outputting data from the memories holding the digital signals are set apart from each other by at least one data clock period of a scanning circuit.

Abstract: To provide an electronic device whose manufacturing cost and weight can be reduced and whose sound quality can be prevented from deteriorating. Speakers 28 are provided on a rear side of a liquid crystal display part 20, inside a casing 12 so as to partly protrude downward from the liquid crystal display part 20, and sound guide ducts 24 linearly extend from a front face side of the speakers 28, and thus the sound guide ducts 24 are not bent. Therefore, even high-frequency sound generated from the speakers 28 can be outputted to an external part of the casing 12 without any sound quality deterioration. Further, the speakers 28 do not have to be disposed on a front face of the casing 12 which is on an outer side of the liquid crystal display part 20, and therefore, an electronic device 10 can be made compact, which can reduce weight and manufacturing cost of the electronic device 10.

Abstract: A navigator receives, through communication with a server, only such map information or locality information as is considered to be necessary, and stores it by overriding with it already used map information and locality information. Thus, the navigator, despite having a small storage capacity, is free from interruption of display. Receiving minimum needed information helps save the communication charge.

Abstract: By causing a rubber product to be immersed into or coated with a treating liquid prepared by adding hydrogen peroxide and other additives such as surfactant, alcohol, thickening agent, other surface tension depressant into an aqueous acetic acid or formic acid solution, it becomes possible to efficiently epoxidize the surface layer of the rubber product to thereby provide the rubber product surface with non-adhesive property, sliding property and other barriering properties, without causing toxic gases and contamination due to powder dust during the manufacturing process and without deteriorating properties inherent in the rubber product such as elasticity, elongation and tensile strength.
