摘要:
A peel-apart monochromatic instant film unit including two separate diffusion transfer sheets, namely, a negative or photosensitive in which a latent image is created as a result of exposure and a positive or image-receiving sheet where the positive image is formed. The photosensitive sheet has a carbon containing paper base support which is provided on its one side with a white paper layer, a titanium dioxide containing polyethylene layer and a photosensitive emulsion layer, in that order, and on the opposite side is optionally provided with a transparent polyethylene layer and a backing layer.

A backlight of a liquid crystal display device is divided into a plurality of regions. A backlight area dimmer sets a dimming value for each of the regions of the backlight according to a characteristic amount of the input image. A backlight dimming limiter sets an upper limit and lower limit of the dimming value set by the backlight area dimmer. In this case, the backlight dimming limiter may set the upper and lower limits of the dimming value according to a combination of at least two pieces of information among illuminance information on the external light, category information on the input image and image mode information set by the user.

A television device structured to automatically adjust the color temperature on the display screen in accordance with the viewing environment includes an external light detection unit or an optical sensor for detecting the illuminance and the tint of the ambient light, and an image quality control unit or a microcomputer for adjusting quality of the video image to be displayed on the display panel. The image quality control unit adjusts the color temperature of the video image to be displayed in accordance with the illuminance value and the tint value detected by the external light detection unit. The optical sensor includes an illuminance sensor for mainly detecting the visible light, and an infrared sensor for mainly detecting the infrared light. The illuminance value and the tint value are obtained based on the output values of those two sensors.
摘要:
An initial light control value calculation section calculates the backlight's initial light control value K0 according to brightness of an inputted image signal for each area. A black area measurement section measures a black area S by obtaining ratio of the number of pixels satisfying Y≦Y0 (Y: brightness signal level, Y0: black level threshold) in the screen. A minimum light control value output section determines a minimum light control value Kmin based on comparison between the measured black area S and a black area threshold S0 and outputs a maximum value permissible for the light control value as the value Kmin when the black area S is the threshold value S0 or less. An LED control signal calculation section outputs a control signal to LED light sources based on a light control value K1 as the higher one of K0 and Kmin.

摘要:
A peel-apart type instant film unit comprising an image receiving sheet separably adhered in a heat sealing manner to a mask member which is peeled apart from the former after the development thereof. There is provided therebetween a weak sealing layer comprising an adhesive layer of a thermoplastic polymer having hydrophilic groups and a separating layer which is alkali resistant and has a good separation property relative to the adhesive layer. The weak sealing layer can provide an easy separation between the separating and adhesive layers so as perfectly to transfer the adhesive layer to the image receiving sheet to provide a fine appearance and a writeable image frame on the image receiving sheet. The mask member is made of any polyethylene compounded paper sheets and is provided with a processing liquid-resisting layer inside the weak sealing layer for the purpose of preventing the permeation of processing liquid thereto.
摘要:
The invention relates to a photographic roll film such as Brownie film, particularly to a sealing tape, used for the photographic roll film, which can seal a roll of film easily and reliably without the need for licking adhesive on a sealing tape as in a conventional one. The sealing tape includes a bonding portion and a release portion which are made of a single tape base. The bonding portion has a bond layer coated on the tape base for securing the sealing tape to a surface of light-shielding paper, the release portion made of a folded-over portion formed by folding over the tape base includes a tacky layer and a release layer inside the folded-over portion which are coated on the tape base separately and directly face each other and an end of the tape base is secured to the end portion of the bond layer.
