A device for producing a product gas from biomass includes a reactor which is delimited by a base part and reactor walls. Data is input into the screen fields using the data entry screen, and then transferred to a one of the card layouts to create the card. In addition, the dot overlap rate in pixel areas having low-density and pixel areas having high-density is low, so it is possible to reduce graininess in low-density areas and suppress a decrease in density in high-density areas. An image sensor may include an array of pixel cells, some or all of which have two photo-conversion devices, and peripheral circuitry for reading out signals from the pixel cells.
