A digital video camera includes a pseudo-saturation calculating circuit by which a pseudo-saturation corresponding to an actual saturation is calculated on the basis of two color difference signals, and a suppression coefficient is calculated by a suppression coefficient calculating circuit on the basis of the pseudo-saturation. Each of the color difference signals are outputted by a selecting circuit in a dot sequential manner, and multiplied by the suppression coefficient in a multiplying circuit. Therefore, a signal in which a low-saturation chrominance signal is outputted from the multiplying circuit, whereby the low-saturation chrominance signal can be suppressed even though a sampling frequency is not increased.

A video signal processing circuit is incorporated in an IC for camcorder in which a camera signal outputted from a CCD image sensor is processed in a digital manner such that luminance and color signals can be outputted. In the IC, a vertical interpolation circuit produces two kinds of vertically interpolated data on the basis of a digital camera signal of one channel within an image area being set by an electronic zoom function. A YC separation circuit receives the two kinds of vertically interpolated data, and an output of the YC separation circuit is applied a horizontal interpolation circuit or an RGB composition circuit. If the YC separation output is applied to the horizontal interpolation circuit, the same outputs two kinds of horizontally interpolated data upon which three primary color signals are composed by the RGB composition circuit. If the YC separation output is applied to the RGB composition circuit, the horizontal interpolation circuit produces two kinds of horizontally interpolated data on the basis of three primary color data outputted by the RGB composition circuit.

A braking/driving control apparatus for a vehicle includes a basic control unit which calculates and outputs a target axle torque based on a target acceleration and a driving resistance of the vehicle and which determines an axle torque for a power train of the vehicle and an axle torque for a braking apparatus of the vehicle based on the calculated target axle torque, a sliding-down prediction determining unit which determines whether there is a possibility that the vehicle slides down rearwards on an uphill road, and a sliding-down preventing process executing unit which performs a process for reducing a possibility that the vehicle slides down, based on a determination result of the sliding-down prediction determining unit. After the sliding-down prediction determining unit determines that there is the possibility, the sliding-down preventing process executing unit controls the basic control unit to calculate and output the target axle torque so as to reach an axle torque which is obtained by reducing a predetermined positive amount form an estimated value of an axle torque necessary for the vehicle to achieve the target acceleration against the driving resistance.

A merged image is generated by merging together a first image obtained by shooting with a reduced exposure time, a second image obtained by shooting with an increased exposure time, and a third image obtained by filtering out a high-frequency component from the first image. Here, a merging ratio at which the second and third images are merged together is determined by use of differential values obtained from the second and third images. Also, a merging ratio at which the first image and the second and third images (a fourth image) are merged together is determined by use of edge intensity values obtained from an image based on the first image.

An easy-to-carry image pickup device is provided to obtain images with multiple view angles in which a target subject is positioned in an appropriate size. When capturing an image of a person as a target subject, the size and position of the person's face in the image are detected as a specified part, and a zoom magnification ratio for a lens unit and a shift amount of the incident light position for a light-axis shifting unit are automatically controlled based on the detected size and position of the person's face, so that the person's face has a predetermined size and is positioned in a predetermined position in the image.

An image-sensing apparatus has: an optical zoom control portion varying the size of the subject image on the source images by optical zooming; a particular subject detection portion detecting the position and size of a particular subject on the source images based on the image data of the source images; a narrow-angle image extraction portion setting a narrow-angle image including the particular subject to set the position and size of the narrow-angle image on image; a wide-angle image extraction portion extracting a wide-angle image that includes the narrow-angle image; a resolution enhancement processing portion cutting out a plurality of narrow-angle images according to a setting in the narrow-angle image extraction portion, to generate a narrow-angle high-resolution image having a number of pixels greater than the number of pixels of the narrow-angle image. The optical zoom control portion controls the factor of the optical zooming such that the ratio of the reference number of pixels to the number of pixels of the narrow-angle image approaches the factor of enlargement by the resolution enhancement processing portion.

摘要:
Based on whether a requisite braking torque is less than a drive torque of the driving wheel, braking force is generated for only driving wheels, or braking force is generated for driven wheels, in addition to that for the driving wheels. Thus, it is possible to maintain the creep speed to the target speed and achieve a suitable front and rear braking force distribution on downward slope roads where a gravity impellent is acting on the vehicle, as well as on flat roads and upward slope roads. The ability to achieve such a suitable front and rear braking force distribution ensures that the driven wheels will not easily lock up on a low μ road surface or the like.
