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 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 MOS type solid-state image pickup device including pixels each of which comprises a photodiode PD, a detection portion N and a transfer transistor QT for transferring the charges accumulated in the photodiode PD to the detection portion N, wherein the gate voltage of the transfer transistor QT when the charges are accumulated in the photodiode PD is set to a negative.
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: Free setting of the angle or direction of a camera is available while the camera is being inserted into a cradle. A cradle for a digital camera is provided, which is capable of confirming a display screen of the camera, changing the recording medium or battery, or mounting or demounting a communication cable or the like while the camera is being mounted on the cradle without deteriorating the camera holding. The cradle has a structure such that a tripod screw hole is formed on the bottom surface of the cradle, thereby capable of fixing the cradle to a tripod while the digital camera is being inserted into the cradle. By making the height of rubber pads equal or higher than that of a tripod base, the cradle can be stably placed on a desk or the like.
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. The scanning converter then performs an interpolation based on the chrominance signals DGi, DRi, and DBi to generate corresponding chrominance signals DGp (DGp-E, DGp-O), DRp (DRp-E, DRp-O), and DBp (DBp-E, DBp-O) on a progressive scanning basis. 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.

Abstract: A solid-state image sensor and a digital cameral capable of executing accurate image-shooting adjustment even in a low illumination environment. A charge coupled device type of image sensor includes red, green and blue pixel cells provided with color filter segments and control cells not provided with color filter segments. When a controller determines that the illumination of a scene to be picked up is short, a digital signal processor generates estimated luminance and contrast values for automatic exposure and automatic focus controls in accordance with the outputs of the control cells. An exposure value and the focal position of a lens are adjusted in accordance with those estimated values. The scene is shot in the form of a still picture in response to a shutter release signal.
Abstract: Electronic data output from CCD is separated into a brightness component Y and color difference components Cb and Cr and an edge is extracted for each of the components. The edge amounts are calculated from the extracted edges and the component having the maximum edge amount is selected. Edge information (for example, edge gradient direction) is calculated based on the selected component having the maximum edge amount, a filter is selected based on the calculated edge information about the component having the maximum edge amount, and smoothing processing is performed for the electronic data output from the CCD based on the filter. 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.
Abstract: The invention is intended to raise the potential at an amplification transistor without increasing a source voltage, and to operate each pixel unit at a lower voltage. A reset transistor and a transfer transistor are serially connected between a driving power source (driving voltage Vdd) and an output of a PD. A floating diffusion (FD) node is provided between a source of the reset transistor and a drain of the transfer transistor. A selection transistor and an amplification transistor are serially connected between a vertical signal line and the driving power source. A gate of the amplification transistor is connected to the FD node. The amplification transistor and the selection transistor are connected at positions reversal to those in a conventional device; namely the amplification transistor is disposed on the side nearer to the vertical signal line. Then, the selection transistor is turned on after the end of reset operation by the reset transistor.
