摘要： When contents of Ti, V, Zr, Nb, and C (mass %) are represented as [Ti], [V], [Zr], [Nb], and [C] respectively, a value of a parameter Q represented by “Q=([Ti]/48+[V]/51+[Zr]/91+[Nb]/93)/([C]/12)” is not less than 0.9 nor more than 1.1. A matrix of a metal structure is a ferrite phase, and the metal structure does not include a non-recrystallized structure. An average grain size of ferrite grains constituting the ferrite phase is not less than 10 μm nor more than 200 μm. A precipitate containing at least one selected from the group consisting of Ti, V, Zr, and Nb exists with a density of 10 μm−3 or more in the ferrite grain. An average grain size of the precipitate is not less than 0.002 μm nor more than 0.2 μm.

摘要： The minimum Sum of Absolute Differences obtained by a motion vector search roughly judges the magnitude of quantization error by whether or not exceeding a predetermined threshold value. When the quantization error is lower, whether or not visually noticeable noise exists in some of the pixels of the current macroblock is judged based on the amount of flatness and noise detected in each of the 4x4 pixel blocks of the current macroblock partitioned into 16 sub-macroblocks. If there is visually noticeable noise, intra-frame coding is selected. When the quantization error is higher, whether or not visually noticeable noise exists in the current macroblock is judged while considering the magnitude of the motion vector. If there is visually noticeable noise, intra-frame coding is selected.

摘要： An object is shot continuously at such a high shutter speed that blur is not caused due to camera shake, and plural shot images are combined such that object images in the plural shot images coincide with each other, whereby one sharp image of the object is obtained. A correction direction mark is displayed together with a through image during a shooting operation. The correction direction mark indicates a direction and amount to be corrected by its size, when a location of the object image in each shot image shifts from an initial location in an initial shot image out of a predetermined allowable range. Watching the correction direction mark, a user can correct the shooting range so as to meet with the initial shooting range, whereby the shooting range can be prevented from shifting greatly from the initial shooting range during the shooting operation.

摘要： A control unit monitors a state of captured image sequentially outputted by an image capturing unit. The control unit carries out a first determination that determines whether or not the state of a captured image satisfies a prescribed condition. When the result is that the prescribed condition is satisfied, the captured image is recorded in a recording unit. The control unit also carries out a second determination that determines whether or not the state of the captured image is appropriate for being subjected to the first determination. When the result is that the state is not appropriate for being subjected to the first determination, a warning is issued to the user to this effect.

摘要： As shown in FIG. 2B, a photographing area is divided into a plurality of blocks. The block at the center of the photographing area is defined as an observation block 31, and the blocks at the periphery of the photographing area are defined as background blocks 32. When the number of background blocks 32 having the largest number of identical motion vectors is larger than a threshold m, when the scalar quantity of the motion vectors of these background blocks 32 with the largest number is larger than a threshold v, and when the scalar quantity of the motion vector of the observation block 31 is smaller than a threshold vc, the digital camera 1 judges that the user is performing a follow shot and there is no blurring of the observed photographic subject, and performs an automatic shooting.

摘要： An image processing apparatus for detecting feature points in inputted images comprising an optical flow detection section. The optical flow detection section serves as: a full feature point detection section for detecting as a full feature point a point whose pixel value changes significantly when in whatever direction the pixel is moved; and a semi feature point detection section for detecting as a semi feature point a point whose pixel value hardly changes when the pixel is moved in a certain direction of the image but the pixel value changes significantly when the pixel is moved in other directions. This enables extracting feature points evenly from all portions of the image and enhancing accuracy in alignment when images are synthesized.

摘要： Feature points are extracted from an image of a plurality of frames. A blurring direction component of a previous frame image is judged from motion vectors of the next frame image acquired with reference to feature points of the extracted previous frame image. Images of the same blurring direction are selected and grouped from the image of a plurality of frames based on that judgment result. After performing position compensation, an additive composite of a grouped composite image is created for each group so that feature points conform to grouped images. Subsequently, inverse transform filter processing is applied to the grouped composite image data and hand shake compensation by group is accomplished which compensates the blurring direction component matched to a group. Upon position compensation, an additive composite is generated of a hand shake compensated image so that feature points of each grouped composite image conform to hand shake compensation.

摘要： An image pick-up apparatus and image pick-up method are provided, in which plural photographed images obtained by a continuous shooting are composed into one image, whereby an image of high image quality and of high resolution is obtained, which is not degraded due to blur. An object is shot continuously at such a high shutter speed that blur is not caused due to camera shake, and plural shot images are combined such that object images in the plural shot images coincide with each other, whereby one sharp image of the object is obtained. A correction direction mark is displayed together with a through image during a shooting operation. The correction direction mark indicates a direction and amount to be corrected by its size, when a location of the object image in each shot image shifts from an initial location in an initial shot image out of a predetermined allowable range. Watching the correction direction mark, a user can correct the shooting range so as to meet with the initial shooting range, whereby the shooting range can be prevented from shifting greatly from the initial shooting range during the shooting operation.

摘要： A television video signal A/D converter apparatus has an A/D converter which samples a television video signal to A/D convert it in accordance with upper and lower reference potentials, and supplies the digital signals to a liquid crystal display device. The apparatus also has detectors which detect digital values of the digital signals from the A/D converter which exceed a predetermined value and are below another predetermined value, and which respectively correspond to the upper and lower reference potentials for A/D conversion by the A/D converter. The digital values exceeding and below the predetermined values are counted by a counter, and the upper and lower reference potentials are determined in accordance with the respective counts and are supplied to the A/D converter.
