Abstract: A main frame of a camera body has a CMOS image sensor and an eyepiece of an optical finder, and the lens unit popped up from the camera body has a taking lens and an objective lens of the optical finder. Light shielding walls are formed on the main frame, and light shielding walls are formed on the lens unit. When the lens unit is popped up, the light shielding walls and the light shielding walls slightly overlap each other, thus preventing a light from the optical finder from entering the CMOS image sensor. Thus, the digital camera has a lens unit popped up from a camera body and prevents unnecessary lights other than a subject light from entering an image pickup device.

Abstract: A sensor includes control circuitry and a pixel. The pixel includes a photo site, a first storage node and a second storage node. The control circuitry causes the pixel to transfer a first collected signal from the photo site to the first storage node during a first period, to transfer a second collected signal from the photo site to the second storage node during a second period that follows the first period, and to transfer the first and second collected signals out of the pixel during a third period that follows the second period.

Abstract: A system which allows a user to transmit image data to a print laboratory technician and receive photo prints at a shop suffers cumbersome personal identification when the print laboratory technician reliably hands photo prints. To solve this problem, an electronic camera transmits image sensing data, and designation information which designates a print service which should print the image sensing data. An image gateway transmits the received image sensing data and a printing instruction for the image sensing data to the print service designated by the received designation information. Upon confirming that the print service has received the image sensing data and printing instruction, the image gateway transmits, to the electronic camera, receipt information which corresponds to the printing instruction and is used to receive a print.

Abstract: A method of automatically focusing a camera determines a position of a focus lens where an amount of a high frequency in an image signal is a maximum. The amount of a high frequency included in an image signal is measured at intervals of multiple focus motor steps. Three of the measured positions (x1, x2, x3) and their corresponding measured high frequency amounts (y1, y2, y3) are identified, where y2 is the largest of the measured high frequency amounts, and x1 and x3 are the nearest measured positions on either side of x2. A quadratic function f(x) is determined for the high frequency amount with respect to the focus lens position x. A position at which a derivative ? f ? ( x ) ? x of the quadratic function f(x) is zero, is determined to be the position corresponding to maximum high frequency amount. Thus, the driving time of the focus motor can be reduced.

Abstract: An imaging apparatus with a timing generator supplying an imaging device with drive pulses. The timing generator has registers for independently storing information required for generating a pulse pattern for the imaging device. A selector selects one of the registers to connect it to a pulse generator. Based on the information stored in the selected register, the pulse generator generates pulses of a pulse pattern for the imaging device. External control circuitry rewrites the information stored in an unselected register from the outside of the timing generator. By repeating the steps of selecting one of the registers and rewriting the information stored in the unselected register, drive pulses with various pulse patterns can be supplied to the imaging device.

Abstract: An information recording device capable of preventing a deterioration of quality of a display image. Pixel counts in each of a horizontal direction and a vertical direction of an image represented by digital image data generated by a CCD, are greater than in an image for which electronic zoom has been implemented. A zoom rate of the electronic zoom to be applied to the image during execution of dubbing of an image file and/or display by an LCD of an image represented by the image file, is limited to not more than a magnification rate upper limit value, which is determined on the basis of the horizontal and vertical direction pixel counts of the image represented by the digital image data generated by the CCD and pixel counts in the horizontal and vertical directions of the image for which the electron zoom has been implemented.

Abstract: A method for determining a pixel output value of an imager; the imager having a plurality of pixels, a reset switch associated with each pixel and a select switch associated with each pixel; due to incident illumination upon a pixel of the imager after a reset period. The method captures a first pixel output value when the reset switch is OFF during a reset period and the select switch is ON during a reset period and captures a second pixel output value when the select switch is ON near an end of an integration period. If the second pixel output value is captured when the select switch is ON near an end of a first integration period, the first pixel output value may be captured when the reset switch is OFF during a reset period preceding the first integration period and the select switch is ON during a reset period preceding the first integration period.

Abstract: The invention provides a convenient way of generating image signals on a progressive scanning basis. Multiple image pickup devices used for an interlaced scanning drive and generate chrominance signal DGi on the interlaced scanning basis with an interlace field and chrominance signals DRi and DBi on the interlaced scanning basis with opposite interlace field. Scanning converter receives the chrominance signal Dgi, DRi and Dbi.

Signal processor receives the resultant chrominance signals DGp, DRp, and DBp. The scanning converter sums the chrominance signals DGp, DRp, and DBp belonging to a predetermined number of frames to obtain a new set of chrominance signals.

The electronic data subjected to the smoothing processing is written into flash memory.

Abstract: An imaging device reads an output level of a pixel circuit constituting a pixel array by supplying current to the pixel circuit. It reads a signal level and reset level from the pixel circuit by supplying it with the current from a current source circuit, and stores them into a line memory. A pixel level of the pixel circuit is obtained by a differential amplifier that outputs the difference between the signal level and reset level of the same pixel circuit. The gate potential of a current copier transistor that supplies the read current is set at a value that enables the read current to take a constant value from column to column of the pixel array. The image device can suppress variations in the current copier circuit provided for each array column of the pixel circuits, thereby reducing string-like noise in the image picked up.

Then, the selection transistor is turned on after the end of reset operation by the reset transistor.
