Abstract: An intake air heating apparatus may include an air pump, an intake chamber, an air heater, and a delivery pipe associated with an intake manifold. When intake air is heated, a throttle valve may be closed, the air pump may be started, and electrical power may be supplied to the air heater. The air flowing from the intake chamber may be heated by the air heater. Thereafter, the air may flow from the delivery pipe into branch pipes and circulate to the intake chamber. At that time, since the throttle valve may be closed, and an intake valve or an exhaust valve of an engine may be closed, the heated air may not flow out and the air temperature in the intake manifold and the intake air heating apparatus may increase.

Abstract: The image of a subject is sensed in a photo studio using a digital still camera, and a thumbnail image containing less data than a high-resolution main image representing the image of the subject is generated. Data representing the generated thumbnail image is transmitted to a file apparatus located in another room. The thumbnail-image data requires a shorter transmission time because it contains a smaller amount of data. As a result, the thumbnail image representing the subject is displayed more rapidly.

Abstract: A deviation DGAIR between a first induction air volume GAIRTH that is calculated (S10) based on a detected value (Gair) of an air flow meter and a second induction air volume GAIRPB that is calculated (S12) based on an absolute pressure (PBA) is calculated (S14), and a mean value DGAIRAVE of the deviation DGAIR is calculated (S16, S18), whereby when a difference DDGAIR between the deviation DGAIR and the mean value DGAIRAVE is larger than a predetermined value DGAIL1 (or when a correction mode AFMMODE is 1), secondary air is determined to be supplied to an engine, and the first induction air volume GAIRTH is then corrected (S24, S26).

Abstract: An omnidirectional endoscope device 1 is provided at a distal end part of an insertion section 12 of an endoscope 10 with an omnidirectional light receiving unit 20 for receiving an incident light from all around the periphery in the peripheral direction and reflecting the light toward a relay lens optical system 13. The insertion section 12 slidably pierces through a retaining cylinder 33. A light guide 35 (illumination light transmitting means) is embedded in the retaining cylinder 33, and an outgoing surface at the distal end of this light guide 35 is faced with a distal end face of the retaining cylinder 33. The retaining cylinder 33 can be operated in a sliding manner by a grip 31 disposed at the basal end. By this, the illumination light can strike upon the view field of the omnidirectional light receiving mechanism regardless whether the inside space of an image to be observed is large or small.

Abstract: A digital electric still camera is provided having a CCD image sensor and a memory card for recording digital image data of picture frames photographed by the CCD image sensor. The image data is compressed before being recorded, and the data compression rate is selectable by operating a picture mode button. The selected data compression rate is recorded along with the image data during photographing. When reproducing a picture frame on a monitor TV, the data compression rate is read together with the image data, so that the image data is expanded in correspondence to the data compression rate, and the data compression rate is displayed on a display device, such as a LCD panel provided on the digital electric still camera, in association with the serial number of the picture frame.

Abstract: A picture-taking system includes a film camera for capturing a photographic image of a subject on photosensitive film, and a video camera having a solid-state electronic image sensing device 12, for outputting a video signal representing the photographic image of the subject. Essentially the same photographic image of the subject is photographed by both the film camera and the video camera under a single strobe flash generated by a strobe light-emission device 40. To achieve this synchronized photography and simplify the synchronized photography control system, it is arranged so that the video camera responds to a photographic trigger signal from a shutter switch by generating, and applying to the film camera, a shutter release signal the vertical synchronizing signal of the video camera as a reference. The shutter of the film camera starts opening in response to the shutter release signal.

Abstract: An amount-of-light-emission control data for controlling the amount of light-emission is corrected so that the amount of strobe light-emission becomes proper. In the adjustment process after manufacturing a digital still camera, a subject is placed in a predetermined position, and is photographed by determining a predetermined guide number GN. A guide number GN corresponding to the amount of light-emission of a strobe 45 is calculated from a video signal obtained by the photography. The predetermined actual guide number GN and the guide number GN corresponding to the actual amount of light-emission are compared with each other, to correct the value of control data for determining the amount of light-emission so that there is no difference therebetween. The corrected or updated value of control data in which the predetermined updated corrected guide number GN and the guide number GN corresponding to the actual amount of light-emission are approximately equal to each other is stored in a memory 6.

Abstract: A video signal, which is obtained from a solid-state electronic image sensing device, is used to obtain a photometric value corresponding to the environment in which a subject is present. Photometric areas that differ for every field in one frame are set within a photographic area of a CCD. A luminance-signal component extracted from the video signal by a Y.sub.L synthesizing circuit is integrated by an integrating circuit, under the control of a CPU, with respect to a horizontal scanning interval and vertical scanning interval corresponding to the photometric area. Obtained integrated values are added field by field and a photometric value is calculated field by field from the value resulting from adding the integrated values.

Abstract: A mechanism for moving an object rectilinearly by reducing the speed of motor rotation and converting this rotational motion into rectilinear motion is provided with a first sensor for generating first pulses having a frequency conforming to the rotational speed of the motor, a second sensor for generating second pulses having a frequency conforming to the reduced rotational speed and a pulse interval which is n times that of the first pulses, and third sensor for generating a third output when the object arrives at a predetermined position. A counter is initialized when the first pulse, second pulse and third output satisfy a predetermined condition.

Whenever the second pulses are generated, the count recorded in the counter is forcibly corrected to the value of n.times.m (where m is 0 or an integer) that is closest to the count.
