Abstract: An object of the present invention is to obtain an image photographed with an image-sensing device using a flash, in which the brightness of the image of the subject of the photograph is proper. An integrated value of brightness of a photographed image is obtained; a weighted evaluation value is calculated; contrast of the photographed image is obtained; a gain of an image signal is obtained by using the evaluation value after which, a suppression gain, by which a value of suppressing the gain fluctuates according to the contrast, is obtained in order to correct the brightness of a photographed subject to the proper brightness; a correction gain for making final corrections to an image by using the gain and the suppression gain is calculated; and the image signal is amplified by a gain adjustment circuit, thereby correcting the photographed image.

Abstract: An image capturing apparatus which records information, indicating a procedure of resolution conversion processing performed on the image, into image data and outputs the image and the information. The image capturing apparatus, which captures a subject, includes an image pick-up unit which captures an image; a resolution conversion unit which performs resolution conversion processing on the image, and a storing unit which stores the image resolution conversion information, which indicates a procedure of the resolution conversion processing by the resolution conversion unit, in association with the image.

Abstract: A digital camera and an image processing method in the digital camera, which make it possible to easily obtain interesting and unexpected images applied with special effects. An imaging system images a subject and converting a subject image into unaltered image data representing an unaltered image of the subject. Then, a special effect selector, which is provided with a random number generator generating a random number, selects one special effect from a plurality of special effects in accordance with the random number. A special effect image processor image-processes the unaltered image data under the special effect selected by the special effect selector so as to obtain special effect image data representing a special effect image. The special effect image data is recorded into an external memory, or sent to an external printer through a communication interface.

Abstract: Moving images can be collectively recorded in one file with ease when the moving images are repeatedly captured in the same place or situation. The digital camera which can capture a moving image and record a captured moving image in a file includes a mode setting dial which sets a single recording mode or a continuous recording mode. The captured moving image is recorded in a newly created file when the single recording mode is set by the mode setting dial, and the captured moving image is additionally recorded in an existing file in which a moving image is recorded when the continuous recording mode is set by the mode setting dial. Therefore, when the moving images are repeatedly captured, the moving images can be collectively recorded in one file with ease, and can be also jointed in captured order.

Abstract: The gradation data is found from image signals for one screen, which are obtained when an image is picked up, and a histogram is made by counting all the gradation data for one screen in every gradation, with a predetermined frequency as an upper limit. Then, a reference minimum value of the image signals is calculated by detecting a point where a cumulative frequency which is counted from a small gradation of the histogram reaches a predetermined rate for total number of the gradation data, and a reference maximum value of the image signals is calculated by detecting a point where a cumulative frequency which is counted from a large gradation of the histogram reaches a predetermined rate. The image processing is carried out in accordance with the calculated reference minimum value and reference maximum value.

Abstract: A film image, which is taken into the developed photographic film, is picked up, and a reference maximum value and a reference minimum value of an image signal are determined by the image signal which is obtained when the image is picked up. The reference maximum value and the reference minimum value are used in the signal processing for adjusting the tone of the image, etc. Moreover, the exposure state of the film image is determined based on at least one of the reference maximum value, the reference minimum value, and the average value. If the exposure state is determined to be underexposured, the gamma in the gamma correction is smaller than the gamma during the standard exposure, so that the middle tone can be prevented from being dark. On the other hand, if the exposure state is determined to be overexposured, the gamma in the gamma correction is larger than the gamma during the standard exposure, so that the middle tone can be prevented from being too bright.

Abstract: The present invention achieves an exposure control for getting an image with the best SN without a mechanical iris and an image processing which is good at the color-reappearance and the gradation property with a simple digital processing circuit. When the film image is read by the line sensor 14 which has an electric shutter function, the electric shutter, the film feeding speed and the analog amplifier 16 are controlled totally so as to obtain images with the best SN from high to low transmittance negatives.

Abstract: A color video thermal printing method for printing a full-color frame image on the basis of a color video signal of a full-color field image by interpolation. Interpolation for at least one of three primary colors is made as follows: sums A1, A2 and A3 of image data D1 and D4; D2 and D5; and D3 and D6 of respectively two pixels P1 and P4; P2 and P5; and P3 and P6 are calculated, assuming the pixels P1, P2 and P3 are aligned in this order in a line of the field image, and the pixels P4, P5 and P6 are aligned in this order in an adjacent line of the field image, wherein the pixels P2 and P5 are aligned in the vertical direction with a pixel Px to be interpolated, and are disposed on opposite sides of the pixel Px. If A1<A2<A3 or A1>A2>A3, differences S1=.vertline.D1-D6.vertline., S2=.vertline.D2-D5.vertline., and S3=.vertline.D3-D4.vertline. are calculated. If S1<S2<S3, an average value (D1+D6)/2 is used as interpolation data.
