  • Patent number: 9715636
    Abstract: By setting a parameter in accordance with features of a unique portion appearing in a print image, the unique portion in the print image is efficiently determined. The image is printed on a sheet along with a relative movement in a main scanning direction of the sheet and a print head on which multiple printing elements are arrayed in a sub-scanning direction. One division area is set such that a size in the main scanning direction is greater than a size in the sub-scanning direction. A shift amount from one division area to another division area is set such that a shift amount in the main scanning direction greater than a shift amount in the sub-scanning direction.

  • Patent number: 9715722
    Abstract: An image pickup apparatus which is capable of setting image quality as desired by a user when performing tone correction according to a luminance histogram of a taken image. A luminance histogram obtaining unit obtains a luminance histogram from image data. A luminance tone correction unit performs tone correction on the image data using a correction curve generated based on the obtained luminance histogram. A user setting unit receives a setting as to a correction intensity of the tone correction from the user and sets parameters for determining coordinate values of control points on the correction curve. A luminance tone control unit generates the correction curve based on the luminance histogram and determines the coordinate value according to the parameters set by the user setting unit.

  • Patent number: 9716840
    Abstract: An image pickup apparatus which is capable of, when performing continuous shooting at high shutter speed under an artificial light source with varying amounts of light, reducing the effects of a change in the amount of light on a picked-up image without decreasing frame speed. A frequency and a characteristic point of a change in the amount of light of flicker are detected based on an image signal read out from an image pickup device. Based on the frequency detected at first timing before continuous shooting is performed and the characteristic point detected at second timing later than the first timing during continuous shooting, a characteristic point of a change in the amount of light of flicker after the second timing is predicted. Timing of light exposure is controlled so as to be coincident with the characteristic point after the second timing.
