摘要： A luminance signal Ya and a color-difference signal Ua/Va constituting an input image signal is transferred to a frame memory (first memory) in the unit of line synchronously with its horizontal synchronous signal and written therein. A memory TG211 reads out a read-out request RRQ. The cycle of this request RRQ is a time computed based on a single vertical effective period of an output image signal Sc and the number of lines objective for rate conversion of an input image signal Sa. The luminance signal Ya and color-difference signal Ua/Va are transferred in the unit of line from the frame memory to rate conversion units (second memory) through buffers. There occurs no deflection in this transfer cycle and in each transfer cycle, the stable data transmission band can be secured.

摘要： An image reading device includes a sensor and circuitry. The sensor reads an image on a recording medium. The circuitry inspects the image and outputs an inspection result. The circuitry excludes an area of the recording medium as a first area from an area to be inspected, based on a type of the recording medium or a position of the recording medium with respect to a reading position at which the sensor reads the image, to determine a second area to be inspected. The circuitry outputs the inspection result based on the second area.

摘要： An edge position detecting apparatus includes a light emitting device, a detecting device, and a calculating circuit. The light emitting device includes a plurality of light sources with different emission wavelengths. The light emitting device irradiates a conveyed object with linear light along a width direction of the conveyed object, the width direction being perpendicular to a conveying direction of the conveyed object. The detecting device detects, at a plurality of positions in the width direction of the conveyed object, intensity of reflected light of light emitted by the light emitting device. The calculating circuit calculates, based on a detection result of the detecting device, a position of an edge of the conveyed object in the width direction.

摘要： An induction heating device and an induction heating method are provided. The entire areas to be heated of the workpiece can be uniformly heated to a predetermined high temperature, and uniform heating is possible even when the workpiece deforms in a non-uniform manner during heating. When areas to be heated are established on a workpiece so as to extend in one direction and the areas to be heated are induction-heated, the deformation amount on one edge of the areas to be heated is different from that on the other. This induction heating device includes: heating coils facing a portion of the areas to be heated when the workpiece is induction-heated; and a relative transfer means for transferring the workpiece and the heating coils along one direction in a relative manner, and the heating coils are disposed so as to correspond to the areas to be heated during the heating period.
